It coordinates the lifecycle, state synchronisation, and error handling of multiple `Application` instances within a single process. It primarily serves "multi-tenant" or "sub-application" scenarios, enabling a Gateway to route requests to different application instances. + +## Core Responsibilities + +1. **Application Registration & Lookup** + - `addApp(app)`: Registers an Application instance with the Supervisor. + - `getApp(appName)`: Retrieves an application by name, supporting lazy bootstrapping (via `appBootstrapper`). + - `hasApp(appName)`: Checks if an application is registered. + - `removeApp(appName)`: Destroys and removes an application. + +2. **State Management** + - Maintains state for each application: `initializing | initialized | running | commanding | stopped | error | not_found`. + - Listens to application events (`maintaining`, `__started`, `afterStop`, `afterDestroy`) and syncs state to the Supervisor. + - Provides `setAppStatus()` / `getAppStatus()` for external queries. + +3. **Error Tracking** + - `setAppError()` / `hasAppError()` / `clearAppError()`: Records application-level errors and emits `appError` events. + +4. **Running Mode Control** + - Supports `single` mode (via `STARTUP_SUBAPP` env var for a specific sub-app) and `multiple` mode. + - `blockApps`: Prevents specific applications from being auto-bootstrapped. + +5. **Bootstrapping & Mutual Exclusion** + - `setAppBootstrapper()`: Registers an application factory function for lazy instantiation. + - `bootStrapApp()`: Uses a Mutex to ensure each application is bootstrapped only once. + +6. **Heartbeat & Activity** + - `touchApp()` / `lastSeenAt`: Records the last access time of an application to determine activity. + +7. **Event Broadcasting** + - Emits `afterAppAdded`, `appStatusChanged`, `appMaintainingMessageChanged`, `appMaintainingStatusChanged`, `appError` for external subscribers. + +## Use Cases + +### 1. Gateway Routing to Multiple Apps +- `Gateway.requestHandler()` parses the target application name from request headers or query params (`x-app`, `__appName`). +- Calls `AppSupervisor.getInstance().getApp(appName)` to retrieve or bootstrap the application instance. +- Decides whether to forward the request, return an error, or trigger startup based on application state. + +### 2. Multi-Tenant Architecture +- Each tenant corresponds to an independent `Application` instance (with shared or isolated databases). +- Supervisor manages tenant application lifecycles, avoiding duplicate creation. + +### 3. Sub-Application Isolation +- In test or development environments, use `STARTUP_SUBAPP` to start only a specific sub-app, speeding up startup. + +### 4. State Monitoring & Admin UI +- Admin dashboards can subscribe to Supervisor events to display real-time application status, errors, and maintenance messages. + +## Dependencies + +- **Depended Upon By**: + - `Application` automatically calls `AppSupervisor.getInstance().addApp(this)` during construction. + - `Gateway` frequently calls Supervisor methods in request handling and startup flows. + - `WSServer` and `IPCSocketServer` retrieve application instances via Supervisor. + - Test code (`__tests__/multiple-application.test.ts`, `__tests__/gateway.test.ts`) validates multi-app scenarios. + +- **Dependencies**: + - `async-mutex`: Ensures mutual exclusion during application bootstrapping. + - `Application` events: Listens to lifecycle hooks to sync state. + +## Removal Feasibility Analysis + +### Scenario 1: Single-App Deployment (No Multi-Tenant Needs) +- **Feasibility**: ✅ **Highly Feasible** +- **Conditions**: + - Application always has only one `main` instance. + - Gateway does not need to route to multiple applications. +- **Refactor Plan**: + - Remove `AppSupervisor` singleton. + - `Application` no longer registers with Supervisor during construction. + - `Gateway` directly holds a `mainApp` reference instead of looking up via Supervisor. + - State management simplified to internal `Application` properties. +- **Benefits**: + - Reduces global singleton dependencies, lowering coupling. + - Simplifies code paths, improving testability. + - Reduces memory overhead (no application registry or state maps). + +### Scenario 2: Multi-App Deployment (Multi-Tenant or Sub-Apps) +- **Feasibility**: ⚠️ **Requires Alternative Solution** +- **Conditions**: + - Need to manage multiple application instances within the same process. + - Gateway needs to dynamically route requests to different applications. +- **Refactor Plan**: + - Transform `AppSupervisor` into a container-registered service (not a global singleton). + - Inject via DI container into `Gateway` and plugins requiring multi-app management. + - State management can optionally persist to Redis (for cluster mode) or remain in-process. +- **Benefits**: + - Eliminates global singleton dependency, supporting multi-instance testing. + - More flexible lifecycle management (multi-app capability can be enabled/disabled as needed). + - Provides extension points for application state sharing in cluster mode. + +### Scenario 3: Cluster Mode +- **Feasibility**: ⚠️ **Requires Redesign** +- **Issues**: + - Current `AppSupervisor` is a process-local singleton, unable to share state across processes. + - Multiple worker processes each maintain independent application registries, potentially causing state inconsistencies. +- **Refactor Plan**: + - Store application state in Redis or a shared database. + - Transform Supervisor into a "state proxy" that reads application state from shared storage. + - Coordinate application bootstrapping and state changes via distributed locks or a leader process. +- **Benefits**: + - Supports true multi-process deployment. + - Application state remains consistent across all workers. + +## Potential Benefits of Removal + +1. **Reduced Complexity** + - Eliminates global singleton, reducing implicit dependencies. + - Simplifies `Application` construction logic (no automatic registration). + +2. **Improved Testability** + - No longer relies on global state; test isolation is more thorough. + - Different application manager implementations can be injected for different test scenarios. + +3. **Better DI Integration** + - Registers application management capability in the container, aligning with 2.0 architecture direction. + - Plugins can depend on application management services as needed, rather than being forced to use a global singleton. + +4. **Flexible Deployment Modes** + - Single-app scenarios avoid multi-app management overhead. + - Multi-app scenarios can choose in-process or distributed implementations. + +## Potential Risks of Removal + +1. **Breaks Existing Multi-Tenant Architecture** + - If the product relies on multi-app routing, removing Supervisor requires an alternative solution. + +2. **Gateway Refactor Cost** + - `Gateway.requestHandler()` heavily depends on Supervisor; routing logic needs rewriting. + +3. **State Sync Complexity** + - Currently, state changes are uniformly managed via Supervisor events; removal requires a new mechanism. + +4. **Test Case Invalidation** + - Tests like `__tests__/multiple-application.test.ts` need rewriting. + +## Recommended Approach + +### Short-Term (TachyBase 2.0 Alpha) +1. **Keep AppSupervisor, but as a Container Service** + - No longer use global singleton; register and resolve via container. + - `Application` retrieves Supervisor from container and registers itself during construction. + - `Gateway` resolves Supervisor via container. + +2. **Abstract Application Management Interface** + - Define `IApplicationRegistry` interface with `register/get/remove/getStatus` methods. + - `AppSupervisor` as default implementation; support lightweight implementation for single-app scenarios (e.g., `SingleAppRegistry`). + +3. **Configurable Multi-App Support** + - Use config option `multiApp: boolean` to decide whether to enable multi-app management. + - Single-app mode automatically uses simplified implementation. + +### Mid-Term (TachyBase 2.0 Beta) +1. **Implement Distributed Application Management** + - Provide `RedisApplicationRegistry` implementation for cluster mode. + - Store application state in Redis, using distributed locks to coordinate bootstrapping. + +2. **Pluginise Gateway Routing** + - Extract multi-app routing logic into a plugin (e.g., `@tego/plugin-multi-app-router`). + - Core Gateway only handles basic HTTP serving; routing strategy provided by plugins. + +### Long-Term (TachyBase 2.x Stable) +1. **Fully Remove AppSupervisor** + - Single-app scenarios no longer need an application manager. + - Multi-app scenarios provided by dedicated plugins; core no longer includes it. + +2. **Standardise Application Lifecycle Protocol** + - Define cross-process application state sync protocol (based on Pub/Sub or gRPC). + - Support application instances running in different processes or even different machines. + +## Conclusion + +- **AppSupervisor is a built-in multi-app management capability**, supporting multi-tenant and sub-application scenarios. +- **Can be removed in single-app scenarios**, with benefits including reduced complexity, improved testability, and better DI integration. +- **Multi-app scenarios require an alternative solution**;

+ + // Reload + await this.reload(options); + await this.start(options); + } +} +``` + +## Comparison with Existing Code + +### Issues with Current Implementation + +1. **EventEmitter Inheritance Pollution** + - `Application` extends `EventEmitter`, adding many unnecessary methods to instances. + - Difficult to control event lifecycle and cleanup. + +2. **AsyncEmitter Mixin Complexity** + - Using `applyMixins` increases code complexity. + - Type inference not friendly, requires `declare emitAsync`. + +3. **Difficult Event Cleanup** + - `reInitEvents()` method relies on `_reinitializable` flag, not generic enough. + - Event listeners may leak on restart. + +4. **Lack of Type Safety** + - Event names and parameter types cannot be checked at compile time. + - Easy to have event name typos or parameter mismatches. + +### Advantages of New Implementation + +1. **Clear Responsibilities** + - `Tego` no longer extends `EventEmitter`, only holds `EventBus` reference. + - Event capabilities injected via container, easy to test and replace. + +2. **Controllable Lifecycle** + - Auto-cleanup of all services (including event listeners) on container disposal. + - Auto-unsubscribe on plugin unload. + +3. **Type Safety** + - Define event types via `TegoEvents` interface. + - Compile-time checking of event names and parameters. + +4. **Better Extensibility** + - Easy to replace `EventBus` implementation (e.g., using Redis Pub/Sub). + - Support event priority, one-time subscription, and other advanced features. + +## Migration Steps + +### Phase 1: Define Interfaces (2.0 Alpha) +1. Define `IContainer` interface and implementation. +2. Define `IEventBus` interface and implementation. +3. Define `TegoEvents` type mapping. + +### Phase 2: Core Refactoring (2.0 Alpha) +1. Create `Tego` class (renamed from `Application`). +2. Remove `EventEmitter` inheritance and `AsyncEmitter` mixin. +3. Create container and event bus in constructor. +4. Change all `this.emitAsync()` to `this.eventBus.emitAsync()`. +5. Change all `this.on()` to `this.eventBus.on()`. + +### Phase 3: Plugin Adaptation (2.0 Beta) +1. Update `Plugin` base class to provide `subscribeEvent()` helper method. +2. Update all built-in plugins to resolve `EventBus` via container. +3. Provide migration guide and sample code. + +### Phase 4: Cleanup & Optimization (2.0 GA) +1. Remove old event cleanup logic like `reInitEvents()`. +2. Remove `applyMixins` related code. +3. Optimize event bus performance (batch publishing, deferred execution, etc.). +4. Complete documentation and tests. + +## Configuration Examples + +### Tego Configuration +```typescript +const tego = new Tego({ + name: 'main', + + // Container configuration + container: { + enableValidation: true, // Enable dependency validation + enableAutoDispose: true // Enable auto-cleanup + }, + + // Event bus configuration + eventBus: { + maxListeners: 100, // Max listener count + errorHandler: (error, event) => { + console.error(`Event error in "${event}":`, error); + } + }, + + // Plugin configuration + plugins: [ + '@tego/module-standard-core', + '@tego/plugin-http-server', + '@tego/plugin-websocket' + ] +}); +``` + +### Plugin Configuration +```typescript +class MyPlugin extends Plugin { + async beforeLoad() { + const container = this.app.container; + + // Register service + container.register('myService', { + useFactory: (container) => { + const logger = container.resolve('logger'); + const eventBus = container.resolve('eventBus'); + return new MyService(logger, eventBus); + } + }, { + scope: 'singleton', + tags: ['plugin:my-plugin'], + dispose: async (service) => await service.close() + }); + } + + async load() { + // Subscribe to events + this.subscribeEvent('beforeStart', async (tego, options) => { + const myService = this.app.container.resolve('myService'); + await myService.initialize(); + }); + } +} +``` + +## Benefits Summary + +1. **Clearer Architecture** + - Container and event bus have clear responsibilities, easy to understand and maintain. + - Remove mixin and inheritance, reduce code complexity. + +2. **Better Testability** + - Container and event bus can be easily mocked. + - Plugin tests no longer depend on global state. + +3. **Stronger Type Safety** + - Event names and parameter types checked at compile time. + - Reduce runtime errors. + +4. **More Flexible Extension** + - Can replace container and event bus implementations. + - Support distributed events (via Redis Pub/Sub, etc.). + +5. **Better Lifecycle Management** + - Auto-cleanup of all services on container disposal. + - Auto-unsubscribe events on plugin unload. + +## Migration Checklist + +- [ ] Define `IContainer` interface and implementation. +- [ ] Define `IEventBus` interface and implementation. +- [ ] Define `TegoEvents` type mapping. +- [ ] Create `Tego` class and remove `EventEmitter` inheritance. +- [ ] Refactor all `emitAsync()` calls. +- [ ] Refactor all `on()` / `once()` calls. +- [ ] Update `Plugin` base class to provide event subscription helper methods. +- [ ] Update all built-in plugins to use container and event bus. +- [ ] Write migration guide and sample code. +- [ ] Write unit tests and integration tests. +- [ ] Update documentation and API reference. +- [ ] Release 2.0 Alpha version and collect feedback. +- [ ] Optimize container and event bus API based on feedback. +- [ ] Complete all cleanup work before 2.0 GA. + diff --git a/packages/core/docs/di-container-eventbus-plan.zh.md b/packages/core/docs/di-container-eventbus-plan.zh.md new file mode 100644 index 0000000000..9283296e28 --- /dev/null +++ b/packages/core/docs/di-container-eventbus-plan.zh.md @@ -0,0 +1,897 @@ +# DI 容器与事件总线设计方案 + +## 概述 + +TachyBase 2.0 将采用显式注册的 DI 容器模式,取消类似 NestJS 的自动扫描机制,改为在 Tego 启动时手动注册服务。同时,将当前基于 `AsyncEmitter` mixin 的事件系统重构为统一的事件总线服务,通过容器注入到需要的组件中。 + +## DI 容器设计 + +### 核心原则 + +1. **显式注册,无自动扫描** + - 不使用装饰器扫描或反射机制自动发现服务。 + - 所有服务在 Tego 启动时通过代码显式注册到容器。 + - 插件在 `beforeLoad` / `load` 阶段注册自己的服务。 + +2. **生命周期绑定** + - 容器随 Tego 实例创建而创建。 + - Tego 重启(`restart()`)时,容器销毁并重新创建。 + - 插件卸载时,相关服务从容器中注销。 + +3. **作用域支持** + - **Singleton(单例)**:整个 Tego 实例共享一个实例(如 Logger、EventBus、ConfigProvider)。 + - **Transient(瞬态)**:每次解析创建新实例(如请求处理器、临时计算服务)。 + - **Scoped(作用域)**:在特定作用域内共享(如请求上下文、插件上下文)。 + +4. **依赖解析** + - 支持构造函数注入、属性注入、方法注入。 + - 支持延迟解析(Lazy Resolution)。 + - 支持可选依赖(Optional Dependencies)。 + +### 容器接口设计 + +```typescript +interface IContainer { + // 注册服务 + register(token: Token, provider: Provider, options?: RegistrationOptions): void;

This document records Gateway's current responsibilities, use cases, and migration considerations. + +## Gateway Current Responsibilities + +### 1. HTTP Server Management +- **Start/Stop HTTP Server**: `start()` / `stop()` methods manage `http.Server` instance. +- **Port & Host Configuration**: Configured via environment variables `APP_PORT` / `APP_HOST` or startup parameters. +- **Request Routing**: `requestHandler()` serves as the core entry point, dispatching requests based on URL paths. + +### 2. Multi-Application Routing +- **Application Selector Middleware**: `addAppSelectorMiddleware()` supports resolving target application via request headers (`x-app`) or query parameters (`__appName`). +- **AppSupervisor Integration**: Retrieves application instances via `AppSupervisor.getInstance().getApp(appName)` and forwards requests. +- **Application State Check**: Checks application state (`initializing`, `running`, `error`, etc.) before forwarding, returning appropriate error responses. + +### 3. Static Asset Serving +- **Client Files**: Serves frontend static assets from `APP_CLIENT_ROOT/dist` directory, supports SPA route rewriting. +- **Upload Files**: Handles file access at `/storage/uploads/` path with compression enabled. +- **Plugin Static Assets**: Exposes static files within plugin packages (via `PLUGIN_STATICS_PATH`), prevents access to `/server/` directory. + +### 4. WebSocket Support +- **WSServer Integration**: Built-in `WSServer` instance handles WebSocket connection upgrades. +- **Connection Management**: Maintains WebSocket client mapping, supports grouped message pushing by tags. +- **Application-Level Event Handling**: + - `Application.registerWSEventHandler()` / `removeWSEventHandler()` allow applications to register custom WebSocket event handlers. + - Supports four event types: `connection`, `message`, `close`, `error`. +- **State Synchronization**: Listens to `AppSupervisor` events (`appError`, `appMaintainingMessageChanged`, `appStatusChanged`), pushes to frontend via WebSocket. + +### 5. IPC Socket Service +- **Inter-Process Communication**: `IPCSocketServer` listens on Unix Socket (`gateway.sock`), receives CLI commands from other processes. +- **Command Forwarding**: Forwards `passCliArgv` type messages to main application for execution. + +### 6. Log Management +- **Application-Grouped**: Creates independent Logger instances for each application (via `Registry`). +- **Request Tracing**: Generates `X-Request-Id` for each request and injects into log context. + +### 7. Error Response +- **Standardized Error Format**: `responseErrorWithCode()` returns unified JSON error responses based on error codes (e.g., `APP_NOT_FOUND`, `APP_INITIALIZING`). +- **Error Definitions**: `errors.ts` defines HTTP status codes and error messages for various application states. + +### 8. Custom Handlers +- **Handler Registration**: `addHandler()` allows registering custom request handlers (matched by URL prefix). + +## Use Case Analysis + +### Case 1: Single-App HTTP Service +- **Current Implementation**: Gateway as sole entry point, forwards requests to `main` application. +- **Dependencies**: `AppSupervisor`, static asset serving, WebSocket. +- **Migration Plan**: Use standard HTTP plugin (e.g., `@tego/plugin-http-server`), directly bind application's Koa callback. + +### Case 2: Multi-Tenant/Sub-App Routing +- **Current Implementation**: Resolves target application via `appSelectorMiddlewares`, Gateway coordinates multiple Application instances. +- **Dependencies**: `AppSupervisor`, application state management, WebSocket state sync. +- **Migration Plan**: Use multi-app routing plugin (e.g., `@tego/plugin-multi-app-gateway`), encapsulate AppSupervisor logic. + +### Case 3: WebSocket Real-Time Communication +- **Current Implementation**: + - `WSServer` handles connection upgrades, message dispatch, tag management. + - `Application.registerWSEventHandler()` provides application-level event hooks. + - Listens to `AppSupervisor` events to push state changes. +- **Dependencies**: `AppSupervisor`, event system. +- **Migration Plan**: Use WebSocket plugin (e.g., `@tego/plugin-websocket`), inject event bus and application registry via container. + +### Case 4: IPC Command Forwarding +- **Current Implementation**: `IPCSocketServer` listens on Unix Socket, receives CLI commands and forwards to main application. +- **Dependencies**: `Application.runAsCLI()`. +- **Migration Plan**: Use IPC plugin (e.g., `@tego/plugin-ipc-server`), resolve CLI executor via container. + +### Case 5: Development Mode Hot Reload +- **Current Implementation**: `watch()` method monitors `storage/app.watch.ts` file changes, triggers restart. +- **Dependencies**: File system, process management. +- **Migration Plan**: Use dev tools plugin (e.g., `@tego/plugin-dev-server`), integrate hot reload logic. + +## Core Dependencies + +### Gateway Dependencies +1. **AppSupervisor**: Retrieve application instances, listen to state changes. +2. **Application**: Forward requests to `app.callback()`, register WebSocket events. +3. **Logger**: Create application-grouped log instances. +4. **Environment Variables**: Read port, paths, socket path configurations. + +### Components Depending on Gateway +1. **Application**: + - `registerWSEventHandler()` / `removeWSEventHandler()` call `Gateway.getInstance()`. +2. **NoticeManager**: + - Push notifications via `Gateway.getInstance()['wsServer']`. +3. **WSServer**: + - Listen to `Gateway.getInstance().on('appSelectorChanged')` to update connection tags. + - Listen to `AppSupervisor` events to push state. +4. **Test Code**: + - `__tests__/gateway.test.ts` validates multi-app routing and WebSocket functionality. + +## Removal Plan + +### Phase 1: Interface Abstraction (2.0 Alpha) +1. **Define HTTP Server Interface** + ```typescript + interface IHttpServer { + start(options: { port: number; host: string }): Promise; + stop(): Promise; + addHandler(handler: Handler): void; + getCallback(): (req: IncomingMessage, res: ServerResponse) => void; + } + ``` + +2. **Define WebSocket Interface** + ```typescript + interface IWebSocketServer { + registerEventHandler(appName: string, eventType: string, handler: Function): void; + removeEventHandler(appName: string, eventType: string, handler: Function): void; + sendToTag(tagType: string, tagValue: string, message: any): void; + } + ``` + +3. **Define Application Router Interface** + ```typescript + interface IAppRouter { + resolveApp(req: IncomingRequest): Promise; + addSelectorMiddleware(middleware: AppSelectorMiddleware): void; + } + ``` + +### Phase 2: Plugin Implementation (2.0 Beta) +1. **Create `@tego/plugin-http-server`** + - Implement `IHttpServer` interface. + - Support single-app mode (directly bind Application callback). + - Provide static asset serving capability (optional). + +2. **Create `@tego/plugin-websocket`** + - Implement `IWebSocketServer` interface. + - Inject event bus and application registry via container. + - Support application-level event hooks. + +3. **Create `@tego/plugin-multi-app-gateway`** + - Implement `IAppRouter` interface. + - Encapsulate `AppSupervisor` logic (or use container-registered application management service). + - Support custom application selector middleware. + +4. **Create `@tego/plugin-ipc-server`** + - Provide IPC Socket service. + - Resolve CLI executor via container. + +### Phase 3: Core Cleanup (2.0 GA) +1. **Remove Gateway-Related Code** + - Delete `src/gateway/` directory. + - Remove `Application.registerWSEventHandler()` / `removeWSEventHandler()`. + - Remove `NoticeManager`'s direct dependency on Gateway. + +2. **Update Application** + - Remove `Gateway.getInstance()` calls. + - Change WebSocket event registration to resolve `IWebSocketServer` via container. + +3. **Update Tests** + - Migrate `__tests__/gateway.test.ts` to corresponding plugin test suites. + +## Migration Considerations + +### 1. Configuration Changes +- **Environment Variables**: + - `APP_PORT`, `APP_HOST` become plugin configuration options. + - `SOCKET_PATH` becomes IPC plugin configuration. + - `PLUGIN_STATICS_PATH`, `APP_PUBLIC_PATH` become static asset plugin configuration. +- **Startup Parameters**: + - `start` command's `--port`, `--host` parameters become plugin parameters. + +### 2. API Changes +- **Application API**: + - `app.registerWSEventHandler()` becomes `container.resolve('websocket').registerEventHandler(app.name, ...)`. + - `app.removeWSEventHandler()` likewise. +- **NoticeManager**: + - Inject `IWebSocketServer` during construction instead of directly accessing Gateway. +- **Plugin Development**: + - Plugins requiring WebSocket functionality declare dependency on `@tego/plugin-websocket`. + +### 3. Deployment Changes +- **Single-App Deployment**: + - Only install `@tego/plugin-http-server`. + - Configure port and static asset paths. +- **Multi-App Deployment**: + - Install `@tego/plugin-multi-app-gateway`. + - Configure application selection strategy (request header, query parameter, domain, etc.). +- **Cluster Mode**: + - Use application management plugin supporting distributed state. + - WebSocket connections need sticky sessions or shared state configuration. + +### 4. Compatibility Handling +- **Provide Adapter Layer** (optional, transition period only): + - Create `@tego/plugin-legacy-gateway` providing API compatible with old interface. + - Mark as deprecated in early 2.x versions, remove in later versions. + +### 5. Testing Strategy +- **Unit Tests**: + - Each plugin independently tests HTTP, WebSocket, routing logic. +- **Integration Tests**: + - Validate complete functionality after plugin combination (HTTP + WebSocket + multi-app routing). +- **Performance Tests**: + - Compare request throughput and WebSocket message latency before/after pluginisation. + +## Plugin Design Recommendations + +### 1. `@tego/plugin-http-server` +- **Responsibility**: Provide basic HTTP service. +- **Configuration**: + ```typescript + { + port: 3000, + host: '0.0.0.0', + staticPaths: [ + { prefix: '/public', directory: './public' }, + { prefix: '/uploads', directory: './storage/uploads' } + ], + compression: true + } + ``` +- **Container Registration**: + - `IHttpServer` interface implementation. + - Provide `addHandler()` method for other plugins to register routes. + +### 2. `@tego/plugin-websocket` +- **Responsibility**: Provide WebSocket service. +- **Configuration**: + ```typescript + { + path: '/ws', + heartbeat: 30000, + maxPayload: 1024 * 1024 + } + ``` +- **Container Registration**: + - `IWebSocketServer` interface implementation. + - Listen to event bus in container, push state changes. + +### 3. `@tego/plugin-multi-app-gateway` +- **Responsibility**: Multi-app routing and state management. +- **Configuration**: + ```typescript + { + defaultApp: 'main', + selectorMiddlewares: [ + { type: 'header', key: 'x-app' }, + { type: 'query', key: '__appName' }, + { type: 'domain', mapping: { 'tenant1.example.com': 'tenant1' } } + ], + bootstrapper: async (appName) => { /* create app instance */ } + } + ``` +- **Container Registration**: + - `IAppRouter` interface implementation. + - `IApplicationRegistry` interface implementation (encapsulate AppSupervisor logic). + +### 4. `@tego/plugin-ipc-server` +- **Responsibility**: Inter-process communication. +- **Configuration**: + ```typescript + { + socketPath: './storage/gateway.sock', + commandTimeout: 60000 + } + ``` +- **Container Registration**: + - Listen on Unix Socket, parse commands and invoke CLI executor via container. + +## Benefits Assessment + +### 1. Architectural Benefits +- **Lighter Core**: Remove HTTP/WebSocket dependencies, core focuses on plugin loading and lifecycle. +- **More Flexible Deployment**: Choose different HTTP server implementations (e.g., Fastify, Express-based). +- **Better Test Isolation**: Core logic can be tested without starting HTTP server. + +### 2. Functional Benefits +- **Pluggable Network Layer**: Support custom protocols (gRPC, MQTT, etc.). +- **Distributed-Friendly**: WebSocket and application state can independently scale to distributed implementations. +- **Finer-Grained Access Control**: Plugins can independently configure access policies. + +### 3. Developer Experience +- **Clearer Responsibility Separation**: HTTP, WebSocket, routing logic separated into different plugins. +- **Easier Extension**: Adding new protocol support only requires developing new plugin, no core modification. +- **Better Documentation**: Each plugin has independent documentation, lowering learning curve. + +## Risks & Challenges + +### 1. Migration Cost +- **Existing Project Refactoring**: All code depending on Gateway needs updates. +- **Documentation Updates**: Need to rewrite deployment, configuration, development guides. +- **Ecosystem Adaptation**: Third-party plugins need to update dependency declarations. + +### 2. Performance Impact +- **Plugin Loading Overhead**: Initialization of multiple plugins may increase startup time. +- **Indirect Call Overhead**: Resolving services via container may be slightly slower than direct calls. + +### 3. Debugging Complexity +- **Issue Localization**: Network layer issues require cross-plugin troubleshooting. +- **Log Aggregation**: Need to unify plugin log format and tracing mechanism. + +## Migration Checklist + +- [ ] Define HTTP, WebSocket, routing-related interfaces. +- [ ] Implement `@tego/plugin-http-server` and pass unit tests. +- [ ] Implement `@tego/plugin-websocket` and validate event pushing. +- [ ] Implement `@tego/plugin-multi-app-gateway` and test multi-app routing. +- [ ] Implement `@tego/plugin-ipc-server` and validate command forwarding. +- [ ] Update `Application` to remove Gateway dependency. +- [ ] Update `NoticeManager` to inject WebSocket service via container. +- [ ] Migrate `__tests__/gateway.test.ts` to plugin test suites. +- [ ] Write migration guide and sample code. +- [ ] Update deployment documentation and configuration templates. +- [ ] Release 2.0 Alpha version and collect feedback. +- [ ] Optimize plugin API and configuration format based on feedback. +- [ ] Complete core cleanup and documentation updates before 2.0 GA. + +## Conclusion + +Gateway removal is a key step in TachyBase 2.0 architecture refactoring, separating network layer capabilities from core to plugins, making the core more focused on plugin loading, event system, and dependency injection. Through proper interface abstraction and plugin design, functionality integrity can be maintained while improving architecture flexibility and extensibility. The migration process requires careful planning to ensure smooth transition of existing functionality and lay the foundation for future distributed deployment and protocol extension. + diff --git a/packages/core/docs/gateway-removal-plan.zh.md b/packages/core/docs/gateway-removal-plan.zh.md new file mode 100644 index 0000000000..32e52d361a --- /dev/null +++ b/packages/core/docs/gateway-removal-plan.zh.md @@ -0,0 +1,317 @@ +# Gateway 移除计划与迁移指南 + +## 概述 + +在 TachyBase 2.0 架构中,核心将不再默认提供 Web Server 能力,`Gateway` 及其相关组件(`WSServer`、`IPCSocketServer`)将从核心移除,改为通过插件形式提供。本文档记录 Gateway 的当前职责、使用场景及迁移注意事项。 + +## Gateway 当前职责 + +### 1.

Dependency Injection Container +- Provide a uniform `Container` API with token registration, scopes, lazy resolution. +- Core registers only essentials: config provider, event bus, lifecycle coordinator, default logger. +- Plugins extend the container in `beforeLoad` / `load` hooks and clean up during `beforeDisable` / `afterDisable`. +- Support container snapshots / rollback to aid hot reload & plugin removal. + +### 2. Plugin System +- Plugin manifest gains container metadata so “bootstrap” plugins can register critical services first. +- Lifecycle works hand-in-hand with the container: register services → consume services → dispose services. +- Plugin state stored via a `PluginRegistry` abstraction that supports in-memory or persistent drivers. + +### 3. Events & Lifecycle +- Keep `emit` / `emitAsync` in the core and document standard event names for cross-plugin interoperability. +- Introduce container-aware lifecycle hooks (e.g. `beforeContainerInit`) if needed. +- In cluster mode, rely on container-provided pub/sub or IPC adapters for broadcasting events. + +### 4. CLI & Configuration +- CLI commands resolve dependencies from the container (logger, registry, lifecycle manager). +- Normalise configuration sources via a `ConfigurationProvider` (files, env vars, remote stores, etc.). +- Core ingests configuration, stores it in the container, plugins enrich or consume the config at load time. + +### 5. Environment & Instance Management +- Expose environment info (runtime mode, cluster role, instance ID) via container tokens. +- Keep `AppSupervisor` as a container-registered singleton to manage multiple app instances. +- Provide cluster coordination services (locks, leader election, broadcast) through container adapters. + +## Migration Playbook + +1. **Define interfaces**: extract DI-friendly contracts (`Logger`, `CacheProvider`, `Scheduler`, …) for existing services. +2. **Pluginise implementations**: move database, gateway, ACL, etc. into plugins that register these contracts. +3. **Rewrite bootstrap**: + - Application init → container creation → core registrations → plugin registration/load → CLI & events binding. + - Strip `Application.init()` of direct `new` calls. +4. **State management**: follow `refactor-shared-state.*.md` for single-writer / Redis / in-process strategies; implement adapters in container. +5. **Breaking change checklist**: mark public APIs, config formats, plugin hooks that change; provide migration hints. +6. **Testing**: create minimal core + plugin combinations, add cluster-mode regression tests. + +## Cluster Compatibility + +- Container services can declare deployment modes (singleton / per-process / distributed). Resolution honours the current topology. +- Plugins choose between shared stores (Redis, DB, message bus) or local state depending on strategy. +- CLI writes run on the leader process; changes propagate via container-managed event bus. +- For schedulers and plugin registry, default to “single writer / multi reader” with the option to swap in fully shared backends. + +## Naming & Module Split Plan + +- **Rename the core class**: + - Rename `Application` (and `application.ts`) to `Tego`, updating all imports, event names, log prefixes, context fields, and configuration keys. + - Align CLI output and error messages with the new name to avoid legacy references. +- **Slim down the implementation**: + - Before renaming, move auxiliary helpers out of the current class into container-owned services or plugins. + - Drop deprecated CLI handlers and legacy APIs so `Tego` exposes only the minimal contract. +- **Package the legacy behaviour as a plugin**: + - Create a `module-standard-core` plugin that re-bundles database, ACL, cache, gateway, cron, i18n, pub/sub, etc. + - The plugin registers services during `beforeLoad`, provides default configuration, and makes the legacy experience opt-in. + - Allow teams to replace or pare down individual capabilities inside the plugin without touching the core runtime. + +## Expected Benefits + +- A lighter core enables faster customisation: different SKUs can compose features via plugins. +- Cloud-native friendliness: container adapters can target managed services without touching the core. +- Easier cluster scaling: flip adapters to distributed implementations to scale horizontally. +- Better testability: each interface is mockable; plugins can be tested in isolation. + +## Breaking Change Highlights + +- Direct property access (`app.db`, `app.logger`, `app.cache`, …) must be replaced with container resolution. +- Plugin manifest & config schemas will change—migration scripts or scaffolds are required. +- CLI commands and flags may shift; automation scripts must be updated. +- Third-party plugins need a v2-compatible release or a shim layer. + +> **Next steps**: maintain migration guides, sample plugins, and container registration recipes under `docs/`.
