Data Binding

Bind JSON, XML, form, query & path params into typed structs, with validation.

Automatic TLS

HTTPS out of the box via Let’s Encrypt, plus HTTP/2 support.

Extensible

Composable middleware and a clean, minimal interface for total control.

Templates

Plug in any Go template engine for fast, flexible HTML rendering.

Get Started

A running server in three steps.

Install

Create a module and add Echo.

go mod init myapp
go get github.com/labstack/echo/v5

Write

Save the Hello World server as server.go.

package main

import (
  "context"
  "net/http"

  "github.com/labstack/echo/v5"
  "github.com/labstack/echo/v5/middleware"
)

func main() {
  // Echo instance
  e := echo.New()

  // Middleware
  e.Use(middleware.RequestLogger())
  e.Use(middleware.Recover())

  // Route => handler
  e.GET("/", func(c *echo.Context) error {
    return c.String(http.StatusOK, "Hello, World!\n")
  })

  // Start server
  sc := echo.StartConfig{Address: ":1323"}
  if err := sc.Start(context.Background(), e); err != nil {
    e.Logger.Error("failed to start server", "error", err)
  }
}
