一个多层次的可扩展Go HTTP框架
BREAKING CHANGE: EventStreamChan signature changed from (chan<- Event, <-chan error) to (eventChan <-chan Event) The caller now creates and passes the channel instead of receiving it. The errChan return value is removed. The old non-blocking design allowed the handler to return before the SSE stream ended, causing ServeHTTP to return the Context to the pool while the internal goroutine was still writing to the pooled writer — a data race across requests. The new blocking design keeps the handler inside EventStreamChan until the event channel is closed or the client disconnects, ensuring the Context remains bound throughout the stream. - Caller creates channel, producer goroutine sends events - EventStreamChan blocks handler until stream ends - Internal goroutine captures stable references (Flusher, context.Context) instead of holding *Context pointer - Nil guard on Flusher type assertion - Add sse_test.go covering blocking, disconnect, and event format - Update docs/sse.md for new API |

Touka(灯花)框架
Touka(灯花) 是一个基于 Go 语言构建的多层次、高性能 Web 框架。其设计目标是为开发者提供更直接的控制、有效的扩展能力,以及针对特定场景的行为优化。
文档
我们提供了详尽的文档来帮助您快速上手并深入了解 Touka:
- 灯花框架简介 (introduction.md)
- 快速开始 (quickstart.md)
- 路由系统 (routing.md)
- 上下文 Context (context.md)
- 中间件 (middleware.md)
- 统一错误处理 (error-handling.md)
- 静态文件与资源 (static-files.md)
- 反向代理 (reverse-proxy.md)
- Server-Sent Events (sse.md)
- 高级特性与优化 (advanced.md)

// 注册路由

// 启动服务器 (支持优雅关闭)
log.Println("Touka Server starting on :8080...")
if err := r.RunShutdown(":8080", 10*time.Second); err != nil {
log.Fatalf("Touka server failed to start: %v", err)
}
}
中间件支持
内置
- Recovery:
r.Use(touka.Recovery())(已包含在touka.Default()中)
