Getting Started with Golang and Fiber

Are you interested in learning how to build web applications using Golang and the Fiber web framework? Look no further! In this tutorial, we will guide you through the process of setting up a basic web server using Golang and Fiber.

Prerequisites

Before we get started, make sure you have Golang installed on your machine. You can download and install Golang from the official Golang website.

Setting up Fiber

To get started with Fiber, we first need to install the Fiber package. Open your terminal and run the following command:

go get -u github.com/gofiber/fiber/v2

This command will download and install the Fiber package in your GOPATH.

Creating a Basic Web Server

Now let’s create a basic web server using Golang and Fiber. Create a new Go file (e.g., main.go) and add the following code:

package main

import (
    "github.com/gofiber/fiber/v2"
)

func main() {
    app := fiber.New()

    app.Get("/", func(c *fiber.Ctx) error {
        return c.SendString("Hello, World!")
    })

    app.Listen(":3000")
}

In this code snippet, we are creating a new Fiber app, defining a route that responds with “Hello, World!” when the root URL is accessed, and then starting the server on port 3000.

Running the Server

To run the server, navigate to the directory where your main.go file is located and run the following command:

go run main.go

You should see a message indicating that the server is up and running. You can now access your web server by visiting http://localhost:3000 in your web browser.

Conclusion

Congratulations! You have successfully set up a basic web server using Golang and Fiber. From here, you can explore more of Fiber’s features and start building more complex web applications. Happy coding!
