Installing Fiber

Install Go

Get the latest version of Go from the official Golang website and follow the instructions.

Create Go Project

Initialize App

go mod init demo

Create main.go

Now create a file called main.go in the project directory write the following code in it:

package main
 
import (
    "log"
 
    "github.com/gofiber/fiber/v2"
)
 
func main() {
    app := fiber.New()
 
    app.Get("/", func(c *fiber.Ctx) error {
        return c.SendString("Hello, World 👋!")
    })
 
    log.Fatal(app.Listen(":3000"))
}

The above code is actually the bare-bones to get the server respond with Hello, World 👋!

Create go.mod

Save the file and run the following command to update your go.mod

go mod tidy

This will create a go.sum file that ensures that future downloads of these modules retrieve the same bits as the first download, to ensure the modules your project depends on do not change unexpectedly, whether for malicious, accidental, or other reasons

Your project folder should contain the following file structure:
/ProjectDirectory
  ├── main.go
  ├── go.mod
  └── go.sum

Run App

Let’s launch our app by calling the following command:

go run main.go
