Migration

Migrate from Gin, Echo, or http.ServeMux to Rivaas Router.

  2 minute read  

This guide helps you migrate from other popular Go routers.

Route Registration

gin := gin.Default()
gin.GET("/users/:id", getUserHandler)
gin.POST("/users", createUserHandler)

e := echo.New()
e.GET("/users/:id", getUserHandler)
e.POST("/users", createUserHandler)

mux := http.NewServeMux()
mux.HandleFunc("/users/", usersHandler)
mux.HandleFunc("/posts/", postsHandler)

r := router.MustNew()
r.GET("/users/:id", getUserHandler)
r.POST("/users", createUserHandler)

Context Usage

func ginHandler(c *gin.Context) {
    id := c.Param("id")
    c.JSON(200, gin.H{"user_id": id})
}

func echoHandler(c echo.Context) error {
    id := c.Param("id")
    return c.JSON(200, map[string]string{"user_id": id})
}

func usersHandler(w http.ResponseWriter, r *http.Request) {
    path := strings.TrimPrefix(r.URL.Path, "/users/")
    userID := strings.Split(path, "/")[0]
    // Manual parameter extraction
}

func rivaasHandler(c *router.Context) {
    id := c.Param("id")
    c.JSON(200, map[string]string{"user_id": id})
}

Middleware

gin.Use(gin.Logger(), gin.Recovery())

e.Use(middleware.Logger())
e.Use(middleware.Recover())

// Manual middleware chaining
handler := Logger(Recovery(mux))
http.ListenAndServe(":8080", handler)

r.Use(Logger(), Recovery())
