Plugins run in a secure sandbox and can provide metadata agents, scrobblers, and other integrations through host services like scheduling, caching, WebSockets, and Subsonic API access. -Navidrome's plugin system is a WebAssembly (WASM) based extension mechanism that enables developers to expand Navidrome's functionality without modifying the core codebase. The plugin system supports several capabilities that can be implemented by plugins: +The plugin system is built on **[Extism](https://extism.org/)**, a cross-language framework for building WebAssembly plugins. This means you can write plugins in any language that Extism supports (Go, Rust, Python, TypeScript, and more) using their Plugin Development Kits (PDKs). -1. **MetadataAgent** - For fetching artist and album information, images, etc. -2. **Scrobbler** - For implementing scrobbling functionality with external services -3. **SchedulerCallback** - For executing code after a specified delay or on a recurring schedule -4. **WebSocketCallback** - For interacting with WebSocket endpoints and handling WebSocket events -5. **LifecycleManagement** - For plugin initialization and configuration (one-time `OnInit` only; not invoked per-request) +**Essential Extism Resources:** +- [Extism Documentation](https://extism.org/docs/overview) – Core concepts and architecture +- [Plugin Development Kits (PDKs)](https://extism.org/docs/concepts/pdk) – Language-specific libraries for writing plugins +- [Go PDK](https://github.com/extism/go-pdk) – Recommended for Go plugins with TinyGo +- [Rust PDK](https://github.com/extism/rust-pdk) – For Rust plugins +- [Python PDK](https://github.com/extism/python-pdk) – Experimental Python support +- [JavaScript PDK](https://github.com/extism/js-pdk) – For TypeScript/JavaScript plugins -## Plugin Architecture +## Table of Contents -The plugin system is built on the following key components: +- [Quick Start](#quick-start) +- [Plugin Basics](#plugin-basics) +- [Capabilities](#capabilities) + - [MetadataAgent](#metadataagent) + - [Scrobbler](#scrobbler) + - [Lifecycle](#lifecycle) +- [Host Services](#host-services) + - [HTTP Requests](#http-requests) + - [Scheduler](#scheduler) + - [Cache](#cache) + - [KVStore](#kvstore) + - [WebSocket](#websocket) + - [Library](#library) + - [Artwork](#artwork) + - [SubsonicAPI](#subsonicapi) + - [Config](#config) + - [Users](#users) +- [Configuration](#configuration) +- [Building Plugins](#building-plugins) +- [Examples](#examples) +- [Security](#security) -### 1.

Create a minimal plugin -### 2. Plugin Protocol - -Plugins communicate with Navidrome using Protocol Buffers (protobuf) over a WASM runtime. The protocol is defined in `plugins/api/api.proto` which specifies the capabilities and messages that plugins can implement. - -### 3. Plugin Adapters - -Adapters bridge between the plugin API and Navidrome's internal interfaces: - -- `wasmMediaAgent` adapts `MetadataAgent` to the internal `agents.Interface` -- `wasmScrobblerPlugin` adapts `Scrobbler` to the internal `scrobbler.Scrobbler` -- `wasmSchedulerCallback` adapts `SchedulerCallback` to the internal `SchedulerCallback` - -* **Plugin Instance Pooling**: Instances are managed in an internal pool (default 8 max, 1m TTL). -* **WASM Compilation & Caching**: Modules are pre-compiled concurrently (max 2) and cached in `[CacheFolder]/plugins`, reducing startup time. The compilation timeout can be configured via `DevPluginCompilationTimeout` in development. - -### 4. Host Services - -Navidrome provides host services that plugins can call to access functionality like HTTP requests and scheduling. -These services are defined in `plugins/host/` and implemented in corresponding host files: - -- HTTP service (in `plugins/host_http.go`) for making external requests -- Scheduler service (in `plugins/host_scheduler.go`) for scheduling timed events -- Config service (in `plugins/host_config.go`) for accessing plugin-specific configuration -- WebSocket service (in `plugins/host_websocket.go`) for WebSocket communication -- Cache service (in `plugins/host_cache.go`) for TTL-based plugin caching -- Artwork service (in `plugins/host_artwork.go`) for generating public artwork URLs -- SubsonicAPI service (in `plugins/host_subsonicapi.go`) for accessing Navidrome's Subsonic API - -### Available Host Services - -The following host services are available to plugins: - -#### HttpService - -```protobuf -// HTTP methods available to plugins -service HttpService { - rpc Get(HttpRequest) returns (HttpResponse); - rpc Post(HttpRequest) returns (HttpResponse); - rpc Put(HttpRequest) returns (HttpResponse); - rpc Delete(HttpRequest) returns (HttpResponse); - rpc Patch(HttpRequest) returns (HttpResponse); - rpc Head(HttpRequest) returns (HttpResponse); - rpc Options(HttpRequest) returns (HttpResponse); -} -``` - -#### ConfigService - -```protobuf -service ConfigService { - rpc GetPluginConfig(GetPluginConfigRequest) returns (GetPluginConfigResponse); -} -``` - -The ConfigService allows plugins to access plugin-specific configuration. See the [config.proto](host/config/config.proto) file for the full API. - -#### ArtworkService - -```protobuf -service ArtworkService { - rpc GetArtistUrl(GetArtworkUrlRequest) returns (GetArtworkUrlResponse); - rpc GetAlbumUrl(GetArtworkUrlRequest) returns (GetArtworkUrlResponse); - rpc GetTrackUrl(GetArtworkUrlRequest) returns (GetArtworkUrlResponse); -} -``` - -Provides methods to get public URLs for artwork images: - -- `GetArtistUrl(id string, size int) string`: Returns a public URL for an artist's artwork -- `GetAlbumUrl(id string, size int) string`: Returns a public URL for an album's artwork -- `GetTrackUrl(id string, size int) string`: Returns a public URL for a track's artwork - -The `size` parameter is optional (use 0 for original size). The URLs returned are based on the server's ShareURL configuration. - -Example: +Create `main.go`: ```go -url := artwork.GetArtistUrl("123", 300) // Get artist artwork URL with size 300px -url := artwork.GetAlbumUrl("456", 0) // Get album artwork URL in original size +package main + +import "github.com/extism/go-pdk" + +func main() {} + +// Implement your capability functions here ``` -#### CacheService - -```protobuf -service CacheService { - // Set a string value in the cache - rpc SetString(SetStringRequest) returns (SetResponse); - - // Get a string value from the cache - rpc GetString(GetRequest) returns (GetStringResponse); - - // Set an integer value in the cache - rpc SetInt(SetIntRequest) returns (SetResponse); - - // Get an integer value from the cache - rpc GetInt(GetRequest) returns (GetIntResponse); - - // Set a float value in the cache - rpc SetFloat(SetFloatRequest) returns (SetResponse); - - // Get a float value from the cache - rpc GetFloat(GetRequest) returns (GetFloatResponse); - - // Set a byte slice value in the cache - rpc SetBytes(SetBytesRequest) returns (SetResponse); - - // Get a byte slice value from the cache - rpc GetBytes(GetRequest) returns (GetBytesResponse); - - // Remove a value from the cache - rpc Remove(RemoveRequest) returns (RemoveResponse); - - // Check if a key exists in the cache - rpc Has(HasRequest) returns (HasResponse); -} -``` - -The CacheService provides a TTL-based cache for plugins. Each plugin gets its own isolated cache instance. By default, cached items expire after 24 hours unless a custom TTL is specified. - -Key features: - -- **Isolated Caches**: Each plugin has its own cache namespace, so different plugins can use the same key names without conflicts -- **Typed Values**: Store and retrieve values with their proper types (string, int64, float64, or byte slice) -- **Configurable TTL**: Set custom expiration times per item, or use the default 24-hour TTL -- **Type Safety**: The system handles type checking, returning "not exists" if there's a type mismatch - -Example usage: - -```go -// Store a string value with default TTL (24 hours) -cacheService.SetString(ctx, &cache.SetStringRequest{ - Key: "user_preference", - Value: "dark_mode", -}) - -// Store an integer with custom TTL (5 minutes) -cacheService.SetInt(ctx, &cache.SetIntRequest{ - Key: "api_call_count", - Value: 42, - TtlSeconds: 300, // 5 minutes -}) - -// Retrieve a value -resp, err := cacheService.GetString(ctx, &cache.GetRequest{ - Key: "user_preference", -}) -if err != nil { - // Handle error -} -if resp.Exists { - // Use resp.Value -} else { - // Key doesn't exist or has expired -} - -// Check if a key exists -hasResp, err := cacheService.Has(ctx, &cache.HasRequest{ - Key: "api_call_count", -}) -if hasResp.Exists { - // Key exists and hasn't expired -} - -// Remove a value -cacheService.Remove(ctx, &cache.RemoveRequest{ - Key: "user_preference", -}) -``` - -See the [cache.proto](host/cache/cache.proto) file for the full API definition. - -#### SchedulerService - -The SchedulerService provides a unified interface for scheduling both one-time and recurring tasks, as well as accessing current time information. See the [scheduler.proto](host/scheduler/scheduler.proto) file for the full API. - -```protobuf -service SchedulerService { - // One-time event scheduling - rpc ScheduleOneTime(ScheduleOneTimeRequest) returns (ScheduleResponse); - - // Recurring event scheduling - rpc ScheduleRecurring(ScheduleRecurringRequest) returns (ScheduleResponse); - - // Cancel any scheduled job - rpc CancelSchedule(CancelRequest) returns (CancelResponse); - - // Get current time in multiple formats - rpc TimeNow(TimeNowRequest) returns (TimeNowResponse); -} -``` - -**Key Features:** - -- **One-time scheduling**: Schedule a callback to be executed once after a specified delay. -- **Recurring scheduling**: Schedule a callback to be executed repeatedly according to a cron expression. -- **Current time access**: Get the current time in standardized formats for time-based operations. - -**TimeNow Function:** - -The `TimeNow` function returns the current time in three formats: - -```protobuf -message TimeNowResponse { - string rfc3339_nano = 1; // RFC3339 format with nanosecond precision - int64 unix_milli = 2; // Unix timestamp in milliseconds - string local_time_zone = 3; // Local timezone name (e.g., "UTC", "America/New_York") -} -``` - -This allows plugins to: - -- Get high-precision timestamps for logging and event correlation -- Perform time-based calculations using Unix timestamps -- Handle timezone-aware operations by knowing the server's local timezone - -Example usage: - -```go -// Get current time information -timeResp, err := scheduler.TimeNow(ctx, &scheduler.TimeNowRequest{}) -if err != nil { - return err -} - -// Use the different time formats -timestamp := timeResp.Rfc3339Nano // "2024-01-15T10:30:45.123456789Z" -unixMs := timeResp.UnixMilli // 1705312245123 -timezone := timeResp.LocalTimeZone // "UTC" -``` - -Plugins using this service must implement the `SchedulerCallback` interface: - -```protobuf -service SchedulerCallback { - rpc OnSchedulerCallback(SchedulerCallbackRequest) returns (SchedulerCallbackResponse); -} -``` - -The `IsRecurring` field in the request allows plugins to differentiate between one-time and recurring callbacks. - -#### WebSocketService - -The WebSocketService enables plugins to connect to and interact with WebSocket endpoints. See the [websocket.proto](host/websocket/websocket.proto) file for the full API. - -```protobuf -service WebSocketService { - // Connect to a WebSocket endpoint - rpc Connect(ConnectRequest) returns (ConnectResponse); - - // Send a text message - rpc SendText(SendTextRequest) returns (SendTextResponse); - - // Send binary data - rpc SendBinary(SendBinaryRequest) returns (SendBinaryResponse); - - // Close a connection - rpc Close(CloseRequest) returns (CloseResponse); -} -``` - -- **Connect**: Establish a WebSocket connection to a specified URL with optional headers -- **SendText**: Send text messages over an established connection -- **SendBinary**: Send binary data over an established connection -- **Close**: Close a WebSocket connection with optional close code and reason - -Plugins using this service must implement the `WebSocketCallback` interface to handle incoming messages and connection events: - -```protobuf -service WebSocketCallback { - rpc OnTextMessage(OnTextMessageRequest) returns (OnTextMessageResponse); - rpc OnBinaryMessage(OnBinaryMessageRequest) returns (OnBinaryMessageResponse); - rpc OnError(OnErrorRequest) returns (OnErrorResponse); - rpc OnClose(OnCloseRequest) returns (OnCloseResponse); -} -``` - -Example usage: - -```go -// Connect to a WebSocket server -connectResp, err := websocket.Connect(ctx, &websocket.ConnectRequest{ - Url: "wss://example.com/ws", - Headers: map[string]string{"Authorization": "Bearer token"}, - ConnectionId: "my-connection-id", -}) -if err != nil { - return err -} - -// Send a text message -_, err = websocket.SendText(ctx, &websocket.SendTextRequest{ - ConnectionId: "my-connection-id", - Message: "Hello WebSocket", -}) - -// Send binary data -_, err = websocket.SendBinary(ctx, &websocket.SendBinaryRequest{ - ConnectionId: "my-connection-id", - Data: []byte{0x01, 0x02, 0x03}, -}) - -// Close the connection when done -_, err = websocket.Close(ctx, &websocket.CloseRequest{ - ConnectionId: "my-connection-id", - Code: 1000, // Normal closure - Reason: "Done", -}) -``` - -#### SubsonicAPIService - -```protobuf -service SubsonicAPIService { - rpc Call(CallRequest) returns (CallResponse); -} -``` - -The SubsonicAPIService provides plugins with access to Navidrome's Subsonic API endpoints. This allows plugins to query and interact with Navidrome's music library data using the same API that external Subsonic clients use. - -Key features: - -- **Library Access**: Query artists, albums, tracks, playlists, and other music library data -- **Search Functionality**: Search across the music library using various criteria -- **Metadata Retrieval**: Get detailed information about music items including ratings, play counts, etc. -- **Authentication Handled**: The service automatically handles authentication using internal auth context -- **JSON Responses**: All responses are returned as JSON strings for easy parsing - -**Important Security Notes:** - -- Plugins must specify a username via the `u` parameter in the URL - this determines which user's library view and permissions apply -- The service uses internal authentication, so plugins don't need to provide passwords or API keys -- All Subsonic API security and access controls apply based on the specified user - -Example usage: - -```go -// Get ping response to test connectivity -resp, err := subsonicAPI.Call(ctx, &subsonicapi.CallRequest{ - Url: "/rest/ping?u=admin", -}) -if err != nil { - return err -} -// resp.Json contains the JSON response - -// Search for artists -resp, err = subsonicAPI.Call(ctx, &subsonicapi.CallRequest{ - Url: "/rest/search3?u=admin&query=Beatles&artistCount=10", -}) - -// Get album details -resp, err = subsonicAPI.Call(ctx, &subsonicapi.CallRequest{ - Url: "/rest/getAlbum?u=admin&id=123", -}) - -// Check for errors -if resp.Error != "" { - // Handle error - could be missing parameters, invalid user, etc. - log.Printf("SubsonicAPI error: %s", resp.Error) -} -``` - -**Common URL Patterns:** - -- `/rest/ping?u=USERNAME` - Test API connectivity -- `/rest/search3?u=USERNAME&query=TERM` - Search library -- `/rest/getArtists?u=USERNAME` - Get all artists -- `/rest/getAlbum?u=USERNAME&id=ID` - Get album details -- `/rest/getPlaylists?u=USERNAME` - Get user playlists - -**Required Parameters:** - -- `u` (username): Required for all requests - determines user context and permissions -- `f=json`: Recommended to get JSON responses (easier to parse than XML) - -The service accepts standard Subsonic API endpoints and parameters. Refer to the [Subsonic API documentation](http://www.subsonic.org/pages/api.jsp) for complete endpoint details, but note that authentication parameters (`p`, `t`, `s`, `c`, `v`) are handled automatically. - -See the [subsonicapi.proto](host/subsonicapi/subsonicapi.proto) file for the full API definition. - -## Plugin Permission System - -Navidrome implements a permission-based security system that controls which host services plugins can access. This system enforces security at load-time by only making authorized services available to plugins in their WebAssembly runtime environment. - -### How Permissions Work - -The permission system follows a **secure-by-default** approach: - -1. **Default Behavior**: Plugins have access to **no host services** unless explicitly declared -2. **Load-time Enforcement**: Only services listed in a plugin's permissions are loaded into its WASM runtime -3. **Runtime Security**: Unauthorized services are completely unavailable - attempts to call them result in "function not exported" errors - -This design ensures that even if malicious code tries to access unauthorized services, the calls will fail because the functions simply don't exist in the plugin's runtime environment. - -### Permission Syntax - -Permissions are declared in the plugin's `manifest.json` file using the `permissions` field as an object: +Create `manifest.json`: ```json { - "name": "my-plugin", - "author": "Plugin Developer", - "version": "1.0.0", - "description": "A plugin that fetches data and caches results", - "website": "https://github.com/plugindeveloper/my-plugin", - "capabilities": ["MetadataAgent"], - "permissions": { - "http": { - "reason": "To fetch metadata from external APIs", - "allowedUrls": { - "https://api.musicbrainz.org": ["GET"], - "https://coverartarchive.org": ["GET"] - }, - "allowLocalNetwork": false - }, - "cache": { - "reason": "To cache API responses and reduce rate limiting" - }, - "subsonicapi": { - "reason": "To query music library for artist and album information", - "allowedUsernames": ["metadata-user"], - "allowAdmins": false - } - } + "name": "My Plugin", + "author": "Your Name", + "version": "1.0.0" } ``` -Each permission is represented as a key in the permissions object. The value must be an object containing a `reason` field that explains why the permission is needed. +### 2. Build with TinyGo and package as .ndp -**Important**: Some permissions require additional configuration fields: +```bash +# Compile to WebAssembly +tinygo build -o plugin.wasm -target wasip1 -buildmode=c-shared . -- **`http`**: Requires `allowedUrls` object mapping URL patterns to allowed HTTP methods, and optional `allowLocalNetwork` boolean -- **`websocket`**: Requires `allowedUrls` array of WebSocket URL patterns, and optional `allowLocalNetwork` boolean -- **`subsonicapi`**: Requires `reason` field, with optional `allowedUsernames` array and `allowAdmins` boolean for fine-grained access control -- **`config`**, **`cache`**, **`scheduler`**, **`artwork`**: Only require the `reason` field - -**Security Benefits of Required Reasons:** - -- **Transparency**: Users can see exactly what each plugin will do with its permissions -- **Security Auditing**: Makes it easier to identify suspicious or overly broad permission requests -- **Developer Accountability**: Forces plugin authors to justify each permission they request -- **Trust Building**: Clear explanations help users make informed decisions about plugin installation - -If no permissions are needed, use an empty permissions object: `"permissions": {}`. - -### Available Permissions - -The following permission keys correspond to host services: - -| Permission | Host Service | Description | Required Fields | -| ------------- | ------------------ | -------------------------------------------------- | ----------------------------------------------------- | -| `http` | HttpService | Make HTTP requests (GET, POST, PUT, DELETE, etc..) | `reason`, `allowedUrls` | -| `websocket` | WebSocketService | Connect to and communicate via WebSockets | `reason`, `allowedUrls` | -| `cache` | CacheService | Store and retrieve cached data with TTL | `reason` | -| `config` | ConfigService | Access Navidrome configuration values | `reason` | -| `scheduler` | SchedulerService | Schedule one-time and recurring tasks | `reason` | -| `artwork` | ArtworkService | Generate public URLs for artwork images | `reason` | -| `subsonicapi` | SubsonicAPIService | Access Navidrome's Subsonic API endpoints | `reason`, optional: `allowedUsernames`, `allowAdmins` | - -#### HTTP Permission Structure - -HTTP permissions require explicit URL whitelisting for security: - -```json -{ - "http": { - "reason": "To fetch artist data from MusicBrainz and album covers from Cover Art Archive", - "allowedUrls": { - "https://musicbrainz.org/ws/2/*": ["GET"], - "https://coverartarchive.org/*": ["GET"], - "https://api.example.com/submit": ["POST"] - }, - "allowLocalNetwork": false - } -} +# Package as .ndp (zip archive) +zip -j my-plugin.ndp manifest.json plugin.wasm ``` -**Fields:** +### 3.

Principle of Least Privilege - -- Plugins start with zero permissions -- Only explicitly requested services are available -- No way to escalate privileges at runtime - -#### 2. Load-time Enforcement - -- Unauthorized services are not loaded into the WASM runtime -- No performance overhead for permission checks during execution -- Impossible to bypass restrictions through code manipulation - -#### 3. Service Isolation - -- Each plugin gets its own isolated service instances -- Plugins cannot interfere with each other's service usage -- Host services are sandboxed within the WASM environment - -### Best Practices for Plugin Developers - -#### Request Minimal Permissions - -```jsonc -// Good: No permissions if none needed -{ - "permissions": {} -} - -// Good: Only request what you need with clear reasoning -{ - "permissions": { - "http": { - "reason": "To fetch artist biography from MusicBrainz database", - "allowedUrls": { - "https://musicbrainz.org/ws/2/artist/*": ["GET"] - }, - "allowLocalNetwork": false - } - } -} - -// Avoid: Requesting unnecessary permissions -{ - "permissions": { - "http": { - "reason": "To fetch data", - "allowedUrls": { - "https://*": ["*"] - }, - "allowLocalNetwork": true - }, - "cache": { - "reason": "For caching" - }, - "scheduler": { - "reason": "For scheduling" - }, - "websocket": { - "reason": "For real-time updates", - "allowedUrls": ["wss://*"], - "allowLocalNetwork": true - } - } -} -``` - -#### Write Clear Permission Reasons - -Provide specific, descriptive reasons for each permission that explain exactly what the plugin does. Good reasons should: - -- Specify **what data** will be accessed/fetched -- Mention **which external services** will be contacted (if applicable) -- Explain **why** the permission is necessary for the plugin's functionality -- Use clear, non-technical language that users can understand - -```jsonc -// Good: Specific and informative -{ - "http": { - "reason": "To fetch album reviews from AllMusic API and artist biographies from MusicBrainz", - "allowedUrls": { - "https://www.allmusic.com/api/*": ["GET"], - "https://musicbrainz.org/ws/2/*": ["GET"] - }, - "allowLocalNetwork": false - }, - "cache": { - "reason": "To cache API responses for 24 hours to respect rate limits and improve performance" - } -} - -// Bad: Vague and unhelpful -{ - "http": { - "reason": "To make requests", - "allowedUrls": { - "https://*": ["*"] - }, - "allowLocalNetwork": true - }, - "cache": { - "reason": "For caching" - } -} -``` - -#### Handle Missing Permissions Gracefully - -Your plugin should provide clear error messages when permissions are missing: - -```go -func (p *Plugin) GetArtistInfo(ctx context.Context, req *api.ArtistInfoRequest) (*api.ArtistInfoResponse, error) { - // This will fail with "function not exported" if http permission is missing - resp, err := p.httpClient.Get(ctx, &http.HttpRequest{Url: apiURL}) - if err != nil { - // Check if it's a permission error - if strings.Contains(err.Error(), "not exported") { - return &api.ArtistInfoResponse{ - Error: "Plugin requires 'http' permission (reason: 'To fetch artist metadata from external APIs') - please add to manifest.json", - }, nil - } - return &api.ArtistInfoResponse{Error: err.Error()}, nil - } - // ... process response -} -``` - -### Troubleshooting Permissions - -#### Common Error Messages - -**"function not exported in module env"** - -- Cause: Plugin trying to call a service without proper permission -- Solution: Add the required permission to your manifest.json - -**"manifest validation failed" or "missing required field"** - -- Cause: Plugin manifest is missing required fields (e.g., `allowedUrls` for HTTP/WebSocket permissions) -- Solution: Ensure your manifest includes all required fields for each permission type - -**Permission silently ignored** - -- Cause: Using a permission key not recognized by current Navidrome version -- Effect: The unknown permission is silently ignored (no error or warning) -- Solution: This is actually normal behavior for forward compatibility - -#### Debugging Permission Issues - -1. **Check the manifest**: Ensure required permissions are spelled correctly and present -2. **Verify required fields**: Check that HTTP and WebSocket permissions include `allowedUrls` and other required fields -3. **Review logs**: Check for plugin loading errors, manifest validation errors, and WASM runtime errors -4. **Test incrementally**: Add permissions one at a time to identify which services your plugin needs -5. **Verify service names**: Ensure permission keys match exactly: `http`, `cache`, `config`, `scheduler`, `websocket`, `artwork`, `subsonicapi` -6. **Validate manifest**: Use a JSON schema validator to check your manifest against the schema - -### Future Considerations - -The permission system is designed for extensibility: - -- **Unknown permissions** are allowed in manifests for forward compatibility -- **New services** can be added with corresponding permission keys -- **Permission scoping** could be added in the future (e.g., read-only vs. read-write access) - -This ensures that plugins developed today will continue to work as the system evolves, while maintaining strong security boundaries. - -## Plugin System Implementation - -Navidrome's plugin system is built using the following key libraries: - -### 1. WebAssembly Runtime (Wazero) - -The plugin system uses [Wazero](https://github.com/tetratelabs/wazero), a WebAssembly runtime written in pure Go. Wazero was chosen for several reasons: - -- **No CGO dependency**: Unlike other WebAssembly runtimes, Wazero is implemented in pure Go, which simplifies cross-compilation and deployment. -- **Performance**: It provides efficient compilation and caching of WebAssembly modules. -- **Security**: Wazero enforces strict sandboxing, which is important for running third-party plugin code safely. - -The plugin manager uses Wazero to: - -- Compile and cache WebAssembly modules -- Create isolated runtime environments for each plugin -- Instantiate plugin modules when they're called -- Provide host functions that plugins can call - -### 2. Go-plugin Framework - -Navidrome builds on [go-plugin](https://github.com/knqyf263/go-plugin), a Go plugin system over WebAssembly that provides: - -- **Code generation**: Custom Protocol Buffer compiler plugin (`protoc-gen-go-plugin`) that generates Go code for both the host and WebAssembly plugins -- **Host function system**: Framework for exposing host functionality to plugins safely -- **Interface versioning**: Built-in mechanism for handling API compatibility between the host and plugins -- **Type conversion**: Utilities for marshaling and unmarshaling data between Go and WebAssembly - -This framework significantly simplifies plugin development by handling the low-level details of WebAssembly communication, allowing plugin developers to focus on implementing capabilities interfaces. - -### 3. Protocol Buffers (Protobuf) - -[Protocol Buffers](https://developers.google.com/protocol-buffers) serve as the interface definition language for the plugin system. Navidrome uses: - -- **protoc-gen-go-plugin**: A custom protobuf compiler plugin that generates Go code for both the Navidrome host and WebAssembly plugins -- Protobuf messages for structured data exchange between the host and plugins - -The protobuf definitions are located in: - -- `plugins/api/api.proto`: Core plugin capability interfaces -- `plugins/host/http/http.proto`: HTTP service interface -- `plugins/host/scheduler/scheduler.proto`: Scheduler service interface -- `plugins/host/config/config.proto`: Config service interface -- `plugins/host/websocket/websocket.proto`: WebSocket service interface -- `plugins/host/cache/cache.proto`: Cache service interface -- `plugins/host/artwork/artwork.proto`: Artwork service interface -- `plugins/host/subsonicapi/subsonicapi.proto`: SubsonicAPI service interface - -### 4. Integration Architecture - -The plugin system integrates these libraries through several key components: - -- **Plugin Manager**: Manages the lifecycle of plugins, from discovery to loading -- **Compilation Cache**: Improves performance by caching compiled WebAssembly modules -- **Host Function Bridge**: Exposes Navidrome functionality to plugins through WebAssembly imports -- **Capability Adapters**: Convert between the plugin API and Navidrome's internal interfaces - -Each plugin method call: - -1. Creates a new isolated plugin instance using Wazero -2. Executes the method in the sandboxed environment -3. Converts data between Go and WebAssembly formats using the protobuf-generated code -4. Cleans up the instance after the call completes - -This stateless design ensures that plugins remain isolated and can't interfere with Navidrome's core functionality or each other. - -## Configuration - -Plugins are configured in Navidrome's main configuration via the `Plugins` section: +Copy `my-plugin.ndp` to your Navidrome plugins folder and enable plugins in your config: ```toml [Plugins] -# Enable or disable plugin support Enabled = true - -# Directory where plugins are stored (defaults to [DataFolder]/plugins) Folder = "/path/to/plugins" ``` -By default, the plugins folder is created under `[DataFolder]/plugins` with restrictive permissions (`0700`) to limit access to the Navidrome user. +--- -### Plugin-specific Configuration +## Plugin Basics -You can also provide plugin-specific configuration using the `PluginConfig` section. Each plugin can have its own configuration map using the **folder name** as the key: +### What is a Plugin? -```toml -[PluginConfig.my-plugin-folder] -api_key = "your-api-key" -user_id = "your-user-id" -enable_feature = "true" +A Navidrome plugin is an `.ndp` package file (zip archive) containing: -[PluginConfig.another-plugin-folder] -server_url = "https://example.com/api" -timeout = "30" -``` +1. **`manifest.json`** – Plugin metadata (name, author, version, permissions) +2. **`plugin.wasm`** – Compiled WebAssembly module with capability functions -These configuration values are passed to plugins during initialization through the `OnInit` method in the `LifecycleManagement` capability. -Plugins that implement the `LifecycleManagement` capability will receive their configuration as a map of string keys and values. - -## Plugin Directory Structure - -Each plugin must be located in its own directory under the plugins folder: +### Plugin Package Structure ``` -plugins/ -├── my-plugin/ -│ ├── plugin.wasm # Compiled WebAssembly module -│ └── manifest.json # Plugin manifest defining metadata and capabilities -├── another-plugin/ -│ ├── plugin.wasm -│ └── manifest.json +my-plugin.ndp (zip archive) +├── manifest.json # Required: Plugin metadata +└── plugin.wasm # Required: Compiled WebAssembly module ``` -**Note**: Plugin identification has changed! Navidrome now uses the **folder name** as the unique identifier for plugins, not the `name` field in `manifest.json`. This means: +### Plugin Naming -- **Multiple plugins can have the same `name` in their manifest**, as long as they are in different folders -- **Plugin loading and commands use the folder name**, not the manifest name -- **Folder names must be unique** across all plugins in your plugins directory +Plugins are identified by their **filename** (without `.ndp` extension), not the manifest `name` field: -This change allows you to have multiple versions or variants of the same plugin (e.g., `lastfm-official`, `lastfm-custom`, `lastfm-dev`) that all have the same manifest name but coexist peacefully. +- `my-plugin.ndp` → plugin ID is `my-plugin` +- The manifest `name` is the display name shown in the UI -### Example: Multiple Plugin Variants +This allows users to have multiple instances of the same plugin with different configs by renaming the files. -``` -plugins/ -├── lastfm-official/ -│ ├── plugin.wasm -│ └── manifest.json # {"name": "LastFM Agent", ...} -├── lastfm-custom/ -│ ├── plugin.wasm -│ └── manifest.json # {"name": "LastFM Agent", ...} -└── lastfm-dev/ - ├── plugin.wasm - └── manifest.json # {"name": "LastFM Agent", ...} -``` +### The Manifest -All three plugins can have the same `"name": "LastFM Agent"` in their manifest, but they are identified and loaded by their folder names: - -```bash -# Load specific variants -navidrome plugin refresh lastfm-official -navidrome plugin refresh lastfm-custom -navidrome plugin refresh lastfm-dev - -# Configure each variant separately -[PluginConfig.lastfm-official] -api_key = "production-key" - -[PluginConfig.lastfm-dev] -api_key = "development-key" -``` - -### Using Symlinks for Plugin Variants - -Symlinks provide a powerful way to create multiple configurations for the same plugin without duplicating files. When you create a symlink to a plugin directory, Navidrome treats the symlink as a separate plugin with its own configuration. - -**Example: Discord Rich Presence with Multiple Configurations** - -```bash -# Create symlinks for different environments -cd /path/to/navidrome/plugins -ln -s /path/to/discord-rich-presence-plugin drp-prod -ln -s /path/to/discord-rich-presence-plugin drp-dev -ln -s /path/to/discord-rich-presence-plugin drp-test -``` - -Directory structure: - -``` -plugins/ -├── drp-prod -> /path/to/discord-rich-presence-plugin/ -├── drp-dev -> /path/to/discord-rich-presence-plugin/ -├── drp-test -> /path/to/discord-rich-presence-plugin/ -``` - -Each symlink can have its own configuration: - -```toml -[PluginConfig.drp-prod] -clientid = "production-client-id" -users = "admin:prod-token" - -[PluginConfig.drp-dev] -clientid = "development-client-id" -users = "admin:dev-token,testuser:test-token" - -[PluginConfig.drp-test] -clientid = "test-client-id" -users = "testuser:test-token" -``` - -**Key Benefits:** - -- **Single Source**: One plugin implementation serves multiple use cases -- **Independent Configuration**: Each symlink has its own configuration namespace -- **Development Workflow**: Easy to test different configurations without code changes -- **Resource Sharing**: All symlinks share the same compiled WASM binary - -**Important Notes:** - -- The **symlink name** (not the target folder name) is used as the plugin ID -- Configuration keys use the symlink name: `PluginConfig.` -- Each symlink appears as a separate plugin in `navidrome plugin list` -- CLI commands use the symlink name: `navidrome plugin refresh drp-dev` - -## Plugin Package Format (.ndp) - -Navidrome Plugin Packages (.ndp) are ZIP archives that bundle all files needed for a plugin. They can be installed using the `navidrome plugin install` command. - -### Package Structure - -A valid .ndp file must contain: - -``` -plugin-name.ndp (ZIP file) -├── plugin.wasm # Required: The compiled WebAssembly module -├── manifest.json # Required: Plugin manifest with metadata -├── README.md # Optional: Documentation -└── LICENSE # Optional: License information -``` - -### Creating a Plugin Package - -To create a plugin package: - -1. Compile your plugin to WebAssembly (plugin.wasm) -2. Create a manifest.json file with required fields -3. Include any documentation files you want to bundle -4. Create a ZIP archive of all files -5. Rename the ZIP file to have a .ndp extension - -### Installing a Plugin Package - -Use the Navidrome CLI to install plugins: - -```bash -navidrome plugin install /path/to/plugin-name.ndp -``` - -This will extract the plugin to a directory in your configured plugins folder. - -## Plugin Management - -Navidrome provides a command-line interface for managing plugins. To use these commands, the plugin system must be enabled in your configuration. - -### Available Commands - -```bash -# List all installed plugins -navidrome plugin list - -# Show detailed information about a plugin package or installed plugin -navidrome plugin info plugin-name-or-package.ndp - -# Install a plugin from a .ndp file -navidrome plugin install /path/to/plugin.ndp - -# Remove an installed plugin (use folder name) -navidrome plugin remove plugin-folder-name - -# Update an existing plugin -navidrome plugin update /path/to/updated-plugin.ndp - -# Reload a plugin without restarting Navidrome (use folder name) -navidrome plugin refresh plugin-folder-name - -# Create a symlink to a plugin development folder -navidrome plugin dev /path/to/dev/folder -``` - -### Plugin Development - -The `dev` and `refresh` commands are particularly useful for plugin development: - -#### Development Workflow - -1. Create a plugin development folder with required files (`manifest.json` and `plugin.wasm`) -2. Run `navidrome plugin dev /path/to/your/plugin` to create a symlink in the plugins directory -3. Make changes to your plugin code -4. Recompile the WebAssembly module -5. Run `navidrome plugin refresh your-plugin-folder-name` to reload the plugin without restarting Navidrome - -The `dev` command creates a symlink from your development folder to the plugins directory, allowing you to edit the plugin files directly in your development environment without copying them to the plugins directory after each change. - -The refresh process: - -- Reloads the plugin manifest -- Recompiles the WebAssembly module -- Updates the plugin registration -- Makes the updated plugin immediately available to Navidrome - -### Plugin Security - -Navidrome provides multiple layers of security for plugin execution: - -1. **WebAssembly Sandbox**: Plugins run in isolated WebAssembly environments with no direct system access -2. **Permission System**: Plugins can only access host services they explicitly request in their manifest (see [Plugin Permission System](#plugin-permission-system)) -3. **File System Security**: The plugins folder is configured with restricted permissions (0700) accessible only by the user running Navidrome -4. **Resource Isolation**: Each plugin instance is isolated and cannot interfere with other plugins or core Navidrome functionality - -The permission system ensures that plugins follow the principle of least privilege - they start with no access to host services and must explicitly declare what they need. This prevents malicious or poorly written plugins from accessing unauthorized functionality. - -Always ensure you trust the source of any plugins you install, and review their requested permissions before installation. - -## Plugin Manifest - -**Capability Names Are Case-Sensitive**: Entries in the `capabilities` array must exactly match one of the supported capabilities: `MetadataAgent`, `Scrobbler`, `SchedulerCallback`, `WebSocketCallback`, or `LifecycleManagement`. -**Manifest Validation**: The `manifest.json` is validated against the embedded JSON schema (`plugins/schema/manifest.schema.json`). Invalid manifests will be rejected during plugin discovery. - -Every plugin must provide a `manifest.json` file that declares metadata, capabilities, and permissions: +Every plugin must include a `manifest.json` file. Example: ```json { - "name": "my-awesome-plugin", - "author": "Your Name", + "name": "My Plugin", + "author": "Author Name", "version": "1.0.0", - "description": "A plugin that does awesome things", - "website": "https://github.com/yourname/my-awesome-plugin", - "capabilities": [ - "MetadataAgent", - "Scrobbler", - "SchedulerCallback", - "WebSocketCallback", - "LifecycleManagement" - ], + "description": "What this plugin does", + "website": "https://example.com", "permissions": { "http": { - "reason": "To fetch metadata from external music APIs" - }, - "cache": { - "reason": "To cache API responses and reduce rate limiting" - }, - "config": { - "reason": "To read API keys and service configuration" - }, - "scheduler": { - "reason": "To schedule periodic data refresh tasks" + "reason": "Fetch metadata from external API", + "requiredHosts": ["api.example.com", "*.musicbrainz.org"] } } } ``` -Required fields: +**Required fields:** `name`, `author`, `version` -- `name`: Display name of the plugin (used for documentation/display purposes; folder name is used for identification) -- `author`: The creator or organization behind the plugin -- `version`: Version identifier (recommended to follow semantic versioning) -- `description`: A brief description of what the plugin does -- `website`: Website URL for the plugin documentation, source code, or homepage (must be a valid URI) -- `capabilities`: Array of capability types the plugin implements -- `permissions`: Object mapping host service names to their configurations (use empty object `{}` for no permissions) +#### Experimental Features -Currently supported capabilities: +Plugins can opt-in to experimental WebAssembly features that may change or be removed in future versions. Currently supported: -- `MetadataAgent` - For implementing media metadata providers -- `Scrobbler` - For implementing scrobbling plugins -- `SchedulerCallback` - For implementing timed callbacks -- `WebSocketCallback` - For interacting with WebSocket endpoints and handling WebSocket events -- `LifecycleManagement` - For handling plugin initialization and configuration +- **`threads`** – Enables WebAssembly threads support (for plugins compiled with multi-threading) -## Plugin Loading Process +```json +{ + "name": "Threaded Plugin", + "author": "Author Name", + "version": "1.0.0", + "experimental": { + "threads": { + "reason": "Required for concurrent audio processing" + } + } +} +``` -1. The Plugin Manager scans the plugins directory and all subdirectories -2. For each subdirectory containing a `plugin.wasm` file and valid `manifest.json`, the manager: - - Validates the manifest and checks for supported capabilities - - Pre-compiles the WASM module in the background - - Registers the plugin using the **folder name** as the unique identifier in the plugin registry -3. Plugins can be loaded on-demand by folder name or all at once, depending on the manager's method calls +> **Note:** Experimental features may have compatibility or performance implications. Use only when necessary. -## Writing a Plugin +--- -### Requirements +## Capabilities -1. Your plugin must be compiled to WebAssembly (WASM) -2. Your plugin must implement at least one of the capability interfaces defined in `api.proto` -3. Your plugin must be placed in its own directory with a proper `manifest.json` +Capabilities define what your plugin can do. They're automatically detected based on which functions you export. -### Plugin Registration Functions +### MetadataAgent -The plugin API provides several registration functions that plugins can call during initialization to register capabilities and obtain host services. These functions should typically be called in your plugin's `init()` function. +Provides artist and album metadata. Export one or more of these functions: -#### Standard Registration Functions +| Function | Input | Output | Description | +|---------------------------|----------------------------|----------------------------------|----------------------| +| `nd_get_artist_mbid` | `{id, name}` | `{mbid}` | Get MusicBrainz ID | +| `nd_get_artist_url` | `{id, name, mbid?}` | `{url}` | Get artist URL | +| `nd_get_artist_biography` | `{id, name, mbid?}` | `{biography}` | Get artist biography | +| `nd_get_similar_artists` | `{id, name, mbid?, limit}` | `{artists: [{name, mbid?}]}` | Get similar artists | +| `nd_get_artist_images` | `{id, name, mbid?}` | `{images: [{url, size}]}` | Get artist images | +| `nd_get_artist_top_songs` | `{id, name, mbid?, count}` | `{songs: [{name, mbid?}]}` | Get top songs | +| `nd_get_album_info` | `{name, artist, mbid?}` | `{name, mbid, description, url}` | Get album info | +| `nd_get_album_images` | `{name, artist, mbid?}` | `{images: [{url, size}]}` | Get album images | + +**Example:** ```go -func RegisterMetadataAgent(agent MetadataAgent) -func RegisterScrobbler(scrobbler Scrobbler) -func RegisterSchedulerCallback(callback SchedulerCallback) -func RegisterLifecycleManagement(lifecycle LifecycleManagement) -func RegisterWebSocketCallback(callback WebSocketCallback) +type ArtistInput struct { + ID string `json:"id"` + Name string `json:"name"` + MBID string `json:"mbid,omitempty"` +} + +type BiographyOutput struct { + Biography string `json:"biography"` +} + +//go:wasmexport nd_get_artist_biography +func ndGetArtistBiography() int32 { + var input ArtistInput + if err := pdk.InputJSON(&input); err != nil { + pdk.SetError(err) + return 1 + } + + // Fetch biography from your data source... + output := BiographyOutput{Biography: "Artist biography..."} + pdk.OutputJSON(output) + return 0 +} ``` -These functions register plugins for the standard capability interfaces: +To use the plugin as a metadata agent, add it to your config: -- **RegisterMetadataAgent**: Register a plugin that provides artist/album metadata and images -- **RegisterScrobbler**: Register a plugin that handles scrobbling to external services -- **RegisterSchedulerCallback**: Register a plugin that handles scheduled callbacks (single callback per plugin) -- **RegisterLifecycleManagement**: Register a plugin that handles initialization and configuration -- **RegisterWebSocketCallback**: Register a plugin that handles WebSocket events +```toml +Agents = "lastfm,spotify,my-plugin" +``` -**Basic Usage Example:** +### Scrobbler + +Integrates with external scrobbling services.

Scrobble events are only sent for users assigned to the plugin through Navidrome's configuration. The `nd_scrobbler_is_authorized` function is called after the server-side user check passes. + +**Manifest permission:** + +```json +{ + "permissions": { + "users": { + "reason": "Receive scrobble events for users assigned to this plugin" + } + } +} +``` + +**NowPlaying/Scrobble Input:** + +```json +{ + "username": "john", + "track": { + "id": "track-id", + "title": "Song Title", + "album": "Album Name", + "artist": "Artist Name", + "albumArtist": "Album Artist", + "duration": 180.5, + "trackNumber": 1, + "discNumber": 1, + "mbzRecordingId": "...", + "mbzAlbumId": "...", + "mbzArtistId": "..." + }, + "timestamp": 1703270400 +} +``` + +**Error Handling:** + +On success, return `0`.

Export this function to run code when your plugin loads: -This function registers a named scheduler callback and returns a scheduler service instance. Named callbacks allow a single plugin to register multiple scheduler callbacks for different purposes, each with its own identifier. +| Function | Input | Output | Description | +|--------------|-------|------------|--------------------------------| +| `nd_on_init` | `{}` | `{error?}` | Called once after plugin loads | -**Parameters:** +Useful for initializing connections, scheduling recurring tasks, etc. -- `name` (string): A unique identifier for this scheduler callback within the plugin. This name is used to route scheduled events to the correct callback handler. -- `cb` (SchedulerCallback): An object that implements the `SchedulerCallback` interface - -**Returns:** - -- `scheduler.SchedulerService`: A scheduler service instance that can be used to schedule one-time or recurring tasks for this specific callback - -**Usage Example** (from Discord Rich Presence plugin): - -```go -func init() { - // Register multiple named scheduler callbacks for different purposes - plugin.sched = api.RegisterNamedSchedulerCallback("close-activity", plugin) - plugin.rpc.sched = api.RegisterNamedSchedulerCallback("heartbeat", plugin.rpc) -} - -// The plugin implements SchedulerCallback to handle "close-activity" events -func (d *DiscordRPPlugin) OnSchedulerCallback(ctx context.Context, req *api.SchedulerCallbackRequest) (*api.SchedulerCallbackResponse, error) { - log.Printf("Removing presence for user %s", req.ScheduleId) - // Handle close-activity scheduling events - return nil, d.rpc.clearActivity(ctx, req.ScheduleId) -} - -// The rpc component implements SchedulerCallback to handle "heartbeat" events -func (r *discordRPC) OnSchedulerCallback(ctx context.Context, req *api.SchedulerCallbackRequest) (*api.SchedulerCallbackResponse, error) { - // Handle heartbeat scheduling events - return nil, r.sendHeartbeat(ctx, req.ScheduleId) -} - -// Use the returned scheduler service to schedule tasks -func (d *DiscordRPPlugin) NowPlaying(ctx context.Context, request *api.ScrobblerNowPlayingRequest) (*api.ScrobblerNowPlayingResponse, error) { - // Schedule a one-time callback to clear activity when track ends - _, err = d.sched.ScheduleOneTime(ctx, &scheduler.ScheduleOneTimeRequest{ - ScheduleId: request.Username, - DelaySeconds: request.Track.Length - request.Track.Position + 5, - }) - return nil, err -} - -func (r *discordRPC) connect(ctx context.Context, username string, token string) error { - // Schedule recurring heartbeats for Discord connection - _, err := r.sched.ScheduleRecurring(ctx, &scheduler.ScheduleRecurringRequest{ - CronExpression: "@every 41s", - ScheduleId: username, - }) - return err -} -``` - -**Key Benefits:** - -- **Multiple Schedulers**: A single plugin can have multiple named scheduler callbacks for different purposes (e.g., "heartbeat", "cleanup", "refresh") -- **Isolated Scheduling**: Each named callback gets its own scheduler service, allowing independent scheduling management -- **Clear Separation**: Different callback handlers can be implemented on different objects within your plugin -- **Flexible Routing**: The scheduler automatically routes callbacks to the correct handler based on the registration name - -**Important Notes:** - -- The `name` parameter must be unique within your plugin, but can be the same across different plugins -- The returned scheduler service is specifically tied to the named callback you registered -- Scheduled events will call the `OnSchedulerCallback` method on the object you provided during registration -- You must implement the `SchedulerCallback` interface on the object you register - -#### RegisterSchedulerCallback vs RegisterNamedSchedulerCallback - -- **Use `RegisterSchedulerCallback`** when your plugin only needs a single scheduler callback -- **Use `RegisterNamedSchedulerCallback`** when your plugin needs multiple scheduler callbacks for different purposes (like the Discord plugin's "heartbeat" and "close-activity" callbacks) - -The named version allows better organization and separation of concerns when you have complex scheduling requirements. - -### Capability Interfaces - -#### Metadata Agent - -A capability fetches metadata about artists and albums. Implement this interface to add support for fetching data from external sources. - -```protobuf -service MetadataAgent { - // Artist metadata methods - rpc GetArtistMBID(ArtistMBIDRequest) returns (ArtistMBIDResponse); - rpc GetArtistURL(ArtistURLRequest) returns (ArtistURLResponse); - rpc GetArtistBiography(ArtistBiographyRequest) returns (ArtistBiographyResponse); - rpc GetSimilarArtists(ArtistSimilarRequest) returns (ArtistSimilarResponse); - rpc GetArtistImages(ArtistImageRequest) returns (ArtistImageResponse); - rpc GetArtistTopSongs(ArtistTopSongsRequest) returns (ArtistTopSongsResponse); - - // Album metadata methods - rpc GetAlbumInfo(AlbumInfoRequest) returns (AlbumInfoResponse); - rpc GetAlbumImages(AlbumImagesRequest) returns (AlbumImagesResponse); -} -``` - -#### Scrobbler - -This capability enables scrobbling to external services. Implement this interface to add support for custom scrobblers. - -```protobuf -service Scrobbler { - rpc IsAuthorized(ScrobblerIsAuthorizedRequest) returns (ScrobblerIsAuthorizedResponse); - rpc NowPlaying(ScrobblerNowPlayingRequest) returns (ScrobblerNowPlayingResponse); - rpc Scrobble(ScrobblerScrobbleRequest) returns (ScrobblerScrobbleResponse); -} -``` - -#### Scheduler Callback - -This capability allows plugins to receive one-time or recurring scheduled callbacks. Implement this interface to add -support for scheduled tasks. See the [SchedulerService](#scheduler-service) for more information. - -```protobuf -service SchedulerCallback { - rpc OnSchedulerCallback(SchedulerCallbackRequest) returns (SchedulerCallbackResponse); -} -``` - -#### WebSocket Callback - -This capability allows plugins to interact with WebSocket endpoints and handle WebSocket events. Implement this interface to add support for WebSocket-based communication. - -```protobuf -service WebSocketCallback { - // Called when a text message is received - rpc OnTextMessage(OnTextMessageRequest) returns (OnTextMessageResponse); - - // Called when a binary message is received - rpc OnBinaryMessage(OnBinaryMessageRequest) returns (OnBinaryMessageResponse); - - // Called when an error occurs - rpc OnError(OnErrorRequest) returns (OnErrorResponse); - - // Called when the connection is closed - rpc OnClose(OnCloseRequest) returns (OnCloseResponse); -} -``` - -Plugins can use the WebSocket host service to connect to WebSocket endpoints, send messages, and handle responses: - -```go -// Define a connection ID first -connectionID := "my-connection-id" - -// Connect to a WebSocket server -connectResp, err := websocket.Connect(ctx, &websocket.ConnectRequest{ - Url: "wss://example.com/ws", - Headers: map[string]string{"Authorization": "Bearer token"}, - ConnectionId: connectionID, -}) -if err != nil { - return err -} - -// Send a text message -_, err = websocket.SendText(ctx, &websocket.SendTextRequest{ - ConnectionId: connectionID, - Message: "Hello WebSocket", -}) - -// Close the connection when done -_, err = websocket.Close(ctx, &websocket.CloseRequest{ - ConnectionId: connectionID, - Code: 1000, // Normal closure - Reason: "Done", -}) -``` +--- ## Host Services -Navidrome provides several host services that plugins can use to interact with external systems and access functionality. Plugins must declare permissions for each service they want to use in their `manifest.json`. +Host services let your plugin call back into Navidrome for advanced functionality. Each service requires declaring the permission in your manifest. -### HTTP Service +### HTTP Requests -The HTTP service allows plugins to make HTTP requests to external APIs and services. To use this service, declare the `http` permission in your manifest. +Make HTTP requests using the Extism PDK's built-in HTTP support. See your [Extism PDK documentation](https://extism.org/docs/concepts/pdk) for more details on making requests. -#### Basic Usage +**Manifest permission:** ```json { "permissions": { "http": { - "reason": "To fetch artist metadata from external music APIs" + "reason": "Fetch metadata from external API", + "requiredHosts": ["api.example.com", "*.musicbrainz.org"] } } } ``` -#### Granular Permissions - -For enhanced security, you can specify granular HTTP permissions that restrict which URLs and HTTP methods your plugin can access: - -```json -{ - "permissions": { - "http": { - "reason": "To fetch album reviews from AllMusic and artist data from MusicBrainz", - "allowedUrls": { - "https://api.allmusic.com": ["GET", "POST"], - "https://*.musicbrainz.org": ["GET"], - "https://coverartarchive.org": ["GET"], - "*": ["GET"] - }, - "allowLocalNetwork": false - } - } -} -``` - -**Permission Fields:** - -- `reason` (required): Clear explanation of why HTTP access is needed -- `allowedUrls` (required): Map of URL patterns to allowed HTTP methods - - - Must contain at least one URL pattern - - For unrestricted access, use: `{"*": ["*"]}` - - Keys can be exact URLs, wildcard patterns, or `*` for any URL - - Values are arrays of HTTP methods: `GET`, `POST`, `PUT`, `DELETE`, `PATCH`, `HEAD`, `OPTIONS`, or `*` for any method - - **Important**: Redirect destinations must also be included in this list. If a URL redirects to another URL not in `allowedUrls`, the redirect will be blocked. - -- `allowLocalNetwork` (optional, default: `false`): Whether to allow requests to localhost/private IPs - -**URL Pattern Matching:** - -- Exact URLs: `https://api.example.com` -- Wildcard subdomains: `https://*.example.com` (matches any subdomain) -- Wildcard paths: `https://example.com/api/*` (matches any path under /api/) -- Global wildcard: `*` (matches any URL - use with caution) - -**Examples:** - -```json -// Allow only GET requests to specific APIs -{ - "allowedUrls": { - "https://api.last.fm": ["GET"], - "https://ws.audioscrobbler.com": ["GET"] - } -} - -// Allow any method to a trusted domain, GET everywhere else -{ - "allowedUrls": { - "https://my-trusted-api.com": ["*"], - "*": ["GET"] - } -} - -// Handle redirects by including redirect destinations -{ - "allowedUrls": { - "https://short.ly/api123": ["GET"], // Original URL - "https://api.actual-service.com": ["GET"] // Redirect destination - } -} - -// Strict permissions for a secure plugin (blocks redirects by not including redirect destinations) -{ - "allowedUrls": { - "https://api.musicbrainz.org/ws/2": ["GET"] - }, - "allowLocalNetwork": false -} -``` - -#### Security Considerations - -The HTTP service implements several security features: - -1. **Local Network Protection**: By default, requests to localhost and private IP ranges are blocked -2. **URL Filtering**: Only URLs matching `allowedUrls` patterns are allowed -3. **Method Restrictions**: HTTP methods are validated against the allowed list for each URL pattern -4. **Redirect Security**: - - Redirect destinations must also match `allowedUrls` patterns and methods - - Maximum of 5 redirects per request to prevent redirect loops - - To block all redirects, simply don't include any redirect destinations in `allowedUrls` - -**Private IP Ranges Blocked (when `allowLocalNetwork: false`):** - -- IPv4: `10.0.0.0/8`, `172.16.0.0/12`, `192.168.0.0/16`, `127.0.0.0/8`, `169.254.0.0/16` -- IPv6: `::1`, `fe80::/10`, `fc00::/7` -- Hostnames: `localhost` - -#### Making HTTP Requests +**Usage:** ```go -import "github.com/navidrome/navidrome/plugins/host/http" +req := pdk.NewHTTPRequest(pdk.MethodGet, "https://api.example.com/data") +req.SetHeader("Authorization", "Bearer " + apiKey) +resp := req.Send() -// GET request -resp, err := httpClient.Get(ctx, &http.HttpRequest{ - Url: "https://api.example.com/data", - Headers: map[string]string{ - "Authorization": "Bearer " + token, - "User-Agent": "MyPlugin/1.0", - }, - TimeoutMs: 5000, -}) - -// POST request with body -resp, err := httpClient.Post(ctx, &http.HttpRequest{ - Url: "https://api.example.com/submit", - Headers: map[string]string{ - "Content-Type": "application/json", - }, - Body: []byte(`{"key": "value"}`), - TimeoutMs: 10000, -}) - -// Handle response -if err != nil { - return &api.Response{Error: "HTTP request failed: " + err.Error()}, nil -} - -if resp.Error != "" { - return &api.Response{Error: "HTTP error: " + resp.Error}, nil -} - -if resp.Status != 200 { - return &api.Response{Error: fmt.Sprintf("HTTP %d: %s", resp.Status, string(resp.Body))}, nil -} - -// Use response data -data := resp.Body -headers := resp.Headers -``` - -### Other Host Services - -#### Config Service - -Access plugin-specific configuration: - -```json -{ - "permissions": { - "config": { - "reason": "To read API keys and service endpoints from plugin configuration" - } - } +if resp.Status() == 200 { + data := resp.Body() + // Process response... } ``` -#### Cache Service +### Scheduler -Store and retrieve data to improve performance: +Schedule one-time or recurring tasks.

Each method call creates a new plugin instance which is destroyed afterward. This has several important implications: +Call Navidrome's Subsonic API internally (no network round-trip). -1. **No in-memory persistence**: Plugins cannot store state between method calls in memory -2. **Each call is isolated**: Variables, configurations, and runtime state don't persist between calls -3. **No shared resources**: Each plugin instance has its own memory space +**Manifest permission:** -This stateless design is crucial for security and stability: - -- Memory leaks in one call won't affect subsequent operations -- A crashed plugin instance won't bring down the entire system -- Resource usage is more predictable and contained - -When developing plugins, keep these guidelines in mind: - -- Don't try to cache data in memory between calls -- Don't store authentication tokens or session data in variables -- If persistence is needed, use external storage or the host's HTTP interface -- Performance optimizations should focus on efficient per-call execution - -### Using Plugin Configuration - -Since plugins are stateless, you can use the `LifecycleManagement` interface to read configuration when your plugin is loaded and perform any necessary setup: - -```go -func (p *myPlugin) OnInit(ctx context.Context, req *api.InitRequest) (*api.InitResponse, error) { - // Access plugin configuration - apiKey := req.Config["api_key"] - if apiKey == "" { - return &api.InitResponse{Error: "Missing API key in configuration"}, nil +```json +{ + "permissions": { + "subsonicapi": { + "reason": "Access library data" + }, + "users": { + "reason": "Access user information for SubsonicAPI authorization" } - - // Validate configuration - serverURL := req.Config["server_url"] - if serverURL == "" { - serverURL = "https://default-api.example.com" // Use default if not specified - } - - // Perform initialization tasks (e.g., validate API key) - httpClient := &http.HttpServiceClient{} - resp, err := httpClient.Get(ctx, &http.HttpRequest{ - Url: serverURL + "/validate?key=" + apiKey, - }) - if err != nil { - return &api.InitResponse{Error: "Failed to validate API key: " + err.Error()}, nil - } - - if resp.StatusCode != 200 { - return &api.InitResponse{Error: "Invalid API key"}, nil - } - - return &api.InitResponse{}, nil + } } ``` -Remember, the `OnInit` method is called only once when the plugin is loaded.

Unlike `pdk.GetConfig()` which only retrieves individual values, this service can list all available configuration keys—useful for discovering dynamic configuration (e.g., user-to-token mappings). -1. **Precompilation**: During plugin discovery, WASM files are read and compiled in the background, with both the MD5 hash of the file bytes and compiled modules cached in memory. +> **Note:** This service is always available and does not require a manifest permission. -2. **Optimized Runtime**: After precompilation completes, plugins use an `optimizedRuntime` wrapper that overrides `CompileModule` to detect when the same WASM bytes are being compiled by comparing MD5 hashes. +**Host functions:** -3. **Cache Hit**: When the generated plugin code calls `os.ReadFile()` and `CompileModule()`, the optimization calculates the MD5 hash of the incoming bytes and compares it with the cached hash. If they match, it returns the pre-compiled module directly. +| Function | Parameters | Returns | +|-----------------|------------|-----------------------------| +| `config_get` | `key` | `value, exists` | +| `config_getint` | `key` | `value, exists` | +| `config_keys` | `prefix` | Array of matching key names | -4. **Performance Benefit**: This eliminates repeated compilation while using minimal memory (16 bytes per plugin for the MD5 hash vs potentially MB of WASM bytes), significantly improving plugin instance creation speed while maintaining full compatibility with the generated API code. +**Usage (with generated SDK):** -5. **Memory Efficiency**: By storing only MD5 hashes instead of full WASM bytes, the optimization scales efficiently regardless of plugin size or count. +```go +import "github.com/navidrome/navidrome/plugins/pdk/go/host" -The optimization is transparent to plugin developers and automatically activates when plugins are successfully precompiled. +// Get a string configuration value +value, exists := host.ConfigGet("api_key") +if exists { + // Use the value +} -## Best Practices +// Get an integer configuration value +count, exists := host.ConfigGetInt("max_retries") -1. **Resource Management**: +// List all keys with a prefix (useful for user-specific config) +keys := host.ConfigKeys("user:") +for _, key := range keys { + // key might be "user:john", "user:jane", etc. +} - - The host handles HTTP response cleanup, so no need to close response objects - - Keep plugin instances lightweight as they are created and destroyed frequently +// List all configuration keys +allKeys := host.ConfigKeys("") +``` -2. **Error Handling**: +### Users - - Use the standard error types when appropriate - - Return descriptive error messages for debugging - - Custom errors are supported and will be propagated to the caller +Access user information for the users that the plugin has been granted access to. This is useful for plugins that need to associate data with specific users or display user information. -3. **Performance**: +**Manifest permission:** - - Remember plugins are stateless, so don't rely on local variables for caching. Use the CacheService for caching data. - - Use efficient algorithms that work well in single-call scenarios +```json +{ + "permissions": { + "users": { + "reason": "Display user information in status updates" + } + } +} +``` -4. **Security**: - - Only request permissions you actually need (see [Plugin Permission System](#plugin-permission-system)) - - Validate inputs to prevent injection attacks - - Don't store sensitive credentials in the plugin code - - Use configuration for API keys and sensitive data +**Important:** Before enabling a plugin that requires the `users` permission, an administrator must configure which users the plugin can access. This can be done in two ways: -## Limitations +1. **Allow all users** – Enable the "Allow all users" toggle in the plugin settings +2. **Select specific users** – Choose individual users from the user list -1. WASM plugins have limited access to system resources -2. Plugin compilation has an initial overhead on first load, as it needs to be compiled to WebAssembly - - Subsequent calls are faster due to caching -3.
