Echo is a fast HTTP router (zero memory allocation) + micro web framework in Go.
- Zippy router.
- Extensible middleware/handler, supports:
- Middleware
func(*echo.Context)func(echo.HandlerFunc) echo.HandlerFuncfunc(http.Handler) http.Handlerhttp.Handlerhttp.HandlerFuncfunc(http.ResponseWriter, *http.Request)
- Handler
func(*echo.Context)http.Handlerhttp.HandlerFuncfunc(http.ResponseWriter, *http.Request)
- Middleware
- Handy encoding/decoding functions.
- Serve static files, including index.
