### Patch Changes

- [#404](https://github.com/esengine/esengine/pull/404) [`902c0a1`](https://github.com/esengine/esengine/commit/902c0a10749f80bd8f499b44154646379d359704) Thanks [@esengine](https://github.com/esengine)! - feat(server): add HTTP file-based routing support / 添加 HTTP 文件路由支持

    New feature that allows organizing HTTP routes in separate files, similar to API and message handlers.
    新功能：支持将 HTTP 路由组织在独立文件中，类似于 API 和消息处理器的文件路由方式。

    ```typescript
    // src/http/login.ts
    import { defineHttp } from '@esengine/server';

    export default defineHttp<{ username: string; password: string }>({
        method: 'POST',
        handler(req, res) {
            const { username, password } = req.body;
            res.json({ token: '...', userId: '...' });
        }
    });
    ```

    Server configuration / 服务器配置:

    ```typescript
    const server = await createServer({
        port: 8080,
        httpDir: 'src/http', // HTTP routes directory / HTTP 路由目录
        httpPrefix: '/api', // Route prefix / 路由前缀
        cors: true
    });
    ```

    File naming convention / 文件命名规则:
    - `login.ts` → POST /api/login
    - `users/profile.ts` → POST /api/users/profile
    - `users/[id].ts` → POST /api/users/:id (dynamic routes / 动态路由)
    - Set `method: 'GET'` in defineHttp for GET requests / 在 defineHttp 中设置 `method: 'GET'` 以处理 GET 请求

    Also includes / 还包括:
    - `defineHttp<TBody>()` helper for type-safe route definitions / 类型安全的路由定义辅助函数
    - Support for merging file routes with inline `http` config / 支持文件路由与内联 `http` 配置合并
    - RPC server supports attaching to existing HTTP server via `server` option / RPC 服务器支持通过 `server` 选项附加到现有 HTTP 服务器

### Patch Changes

- feat(server): add HTTP file-based routing support

    New feature that allows organizing HTTP routes in separate files, similar to API and message handlers:

    ```typescript
    // src/http/login.ts
    import { defineHttp } from '@esengine/server';

    export default defineHttp<{ username: string; password: string }>({
        method: 'POST',
        handler(req, res) {
            const { username, password } = req.body;
            // ... authentication logic
            res.json({ token: '...', userId: '...' });
        }
    });
    ```

    Server configuration:

    ```typescript
    const server = await createServer({
        port: 8080,
        httpDir: 'src/http', // HTTP routes directory
        httpPrefix: '/api', // Route prefix
        cors: true
    });
    ```

    File naming convention:
    - `login.ts` → POST /api/login
    - `users/profile.ts` → POST /api/users/profile
    - `users/[id].ts` → POST /api/users/:id (dynamic routes)
    - Set `method: 'GET'` in defineHttp for GET requests

    Also includes:
    - `defineHttp<TBody>()` helper function for type-safe route definitions
    - Support for merging file routes with inline `http` config
    - RPC server now supports attaching to existing HTTP server via `server` option

## 1.1.1

### Patch Changes

- [#374](https://github.com/esengine/esengine/pull/374) [`a000cc0`](https://github.com/esengine/esengine/commit/a000cc07d7cebe8ccbfa983fde610296bfba2f1b) Thanks [@esengine](https://github.com/esengine)! - feat: export RpcClient and connect from main entry point

    Re-export `RpcClient`, `connect`, and related types from the main entry point for better compatibility with bundlers (Cocos Creator, Vite, etc.) that may have issues with subpath exports.

    ```typescript
    // Now works in all environments:
    import { rpc, RpcClient, connect } from '@esengine/rpc';

    // Subpath import still supported:
    import { RpcClient } from '@esengine/rpc/client';
    ```
