Middlewares

Fuego supports net/http middlewares.

It means that all existing middlewares for net/http, including the ones from chi and gorilla can be used with Fuego! 🔥

You can use them to add functionalities to your routes, such as logging, authentication, etc.

App-level middlewares

You can add middlewares to the whole server using the Use method:

package main

import (
	"net/http"

	"github.com/go-fuego/fuego"
)

func main() {
	s := fuego.NewServer()

	// Add a middleware to the whole server
	fuego.Use(s, func(next http.Handler) http.Handler {
		return http.HandlerFunc(func(w http.ResponseWriter, r *http.Request) {
			// Do something before the request
			next.ServeHTTP(w, r)
			// Do something after the request
		})
	})

	fuego.Use(s, myMiddleware)

	fuego.Get(s, "/", myController)

	s.Run()
}

Group middlewares

You can also add middlewares to a group of routes using the Group method:

package main

import (
	"net/http"

	"github.com/go-fuego/fuego"
)

func main() {
	s := fuego.NewServer()

	// Add a middleware to a group of routes
	api := fuego.Group(s, "/api")

	fuego.Use(api, func(next http.Handler) http.Handler {
		return http.HandlerFunc(func(w http.ResponseWriter, r *http.Request) {
			// Do something before the request
			// Only affects routes in the group
			next.ServeHTTP(w, r)
			// Do something after the request
		})
	})

	// Requests to /api will go through the middleware
	fuego.Get(api, "/", myController)

	// Requests to / will NOT! go through the middleware
	fuego.Get(s, "/", myController)

	s.Run()
}

Route middlewares

You can also add middlewares to a single route. Simply add the middlewares as the last arguments of the route handler:

package main

import (
	"github.com/go-fuego/fuego"
)

func main() {
	s := fuego.NewServer()

	// Declare the middlewares after the route handler
	fuego.Get(s, "/", myController, middleware1, middleware2, middleware3)

	s.Run()
}
