Fiber Simple REST API

package main

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

type Todo struct {
    ID        int    `json:"id"`
    Title     string `json:"title"`
    Completed bool   `json:"completed"`
}

var todos []Todo

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

    app.Get("/todos", func(c *fiber.Ctx) error {
        return c.JSON(todos)
    })

    app.Post("/todos", func(c *fiber.Ctx) error {
        var todo Todo
        if err := c.BodyParser(&todo); err != nil {
        return err
        }
        todos = append(todos, todo)
        return c.Status(201).JSON(todo)
    })

    app.Listen(":3000")
}

Demonstrates a simple Fiber application with routes for listing and creating Todo items.

Frequently Asked Questions about Fiber

What is Fiber?

What are the primary use cases for Fiber?

High-performance REST APIs. Microservices and cloud-native applications. Real-time web applications. Backend services for mobile and web clients. IoT and messaging platforms

What are the strengths of Fiber?

Blazing fast due to Go runtime. Simple and intuitive API. Lightweight and minimal dependencies. Built-in support for common middleware. Scales efficiently in concurrent environments

What are the limitations of Fiber?

Smaller ecosystem compared to frameworks like ASP.NET Core or Laravel. Fewer tutorials and enterprise resources. Not ideal for extremely complex server-side rendering projects. Limited built-in ORM (requires third-party libraries). Less opinionated structure may lead to inconsistent project organization

How can I practice Fiber typing speed?

CodeSpeedTest offers 1+ real Fiber code examples for typing practice. You can measure your WPM, track accuracy, and improve your coding speed with guided exercises.
