- Fast 🚀 HTTP router which smartly resolves conflicting routes.
- Fast router which smartly resolves conflicting routes.
- Extensible middleware/handler, supports:
- Middleware
func(*echo.Context)
func(*echo.Context) error
func(echo.HandlerFunc) echo.HandlerFunc
func(http.Handler) http.Handler
http.Handler
http.HandlerFunc
func(http.ResponseWriter, *http.Request)
func(http.ResponseWriter, *http.Request) error
- Handler
func(*echo.Context)
func(*echo.Context) error
http.Handler
http.HandlerFunc
func(http.ResponseWriter, *http.Request)
func(http.ResponseWriter, *http.Request) error
- Middleware
- Sub routing with groups.
- Handy encoding/decoding functions.
- Serve static files, including index.
- Centralized HTTP error handling.
- Use a customized function to bind request body to a Go type.
- Register a view render so you can use any HTML templating engine.
