Project Setup

Create a new project folder and initialize a Go module:

cd my-fiber-app
go mod init github.com/yourusername/my-fiber-app

Install Fiber

Use Go modules to install Fiber:

go get github.com/gofiber/fiber/v2

Folder Structure

Organize your project like this:

my-fiber-app/
├── main.go
├── go.mod
├── go.sum
├── routes/
│   └── routes.go
├── controllers/
│   └── example_controller.go
├── models/
│   └── example_model.go
├── utils/
│   └── helpers.go
└── config/
    └── config.go

Example main.go

package main
 
import (
    "github.com/gofiber/fiber/v2"
    "my-fiber-app/routes"
)
 
func main() {
    app := fiber.New()
 
    // Setup routes
    routes.Setup(app)
 
    // Start server
    app.Listen(":3000")
}

Example Routes

package routes
 
import (
    "github.com/gofiber/fiber/v2"
    "my-fiber-app/controllers"
)
 
func Setup(app *fiber.App) {
    app.Get("/", controllers.Home)
    app.Get("/ping", controllers.Ping)
}

Example Controller

package controllers
 
import "github.com/gofiber/fiber/v2"
 
func Home(c *fiber.Ctx) error {
    return c.SendString("Welcome to Fiber!")
}
 
func Ping(c *fiber.Ctx) error {
    return c.JSON(fiber.Map{"message": "pong"})
}
