How can I group routes in Gin to create a cleaner and more structured codebase?

Grouping Routes in Gin

Gin makes it easy to organize and manage routes in your application. By grouping routes into different files, you can maintain a clean and structured codebase.

Implementation

1. Create a routes.go file: This file will act as the central hub for registering and managing routes.

<code class="go">package app

import "github.com/gin-gonic/gin"

type routes struct {
    router *gin.Engine
}

func NewRoutes() routes {
    r := routes{
        router: gin.Default(),
    }

    // Add routes here...

    return r
}</code>

2. Group routes: In other files, you can create route groups and add handlers to them based on the base path.

ping.go:

<code class="go">package app

func (r routes) addPing(rg *gin.RouterGroup) {
    ping := rg.Group("/ping")

    ping.GET("/", pongFunction)
}

func pongFunction(c *gin.Context) {
    // Handle ping GET request...
}</code>

3. Start the application: In a file like main.go, instantiate the routes struct and start the server.

<code class="go">package main

import "app"

func main() {
    r := app.NewRoutes()
    r.Run()
}</code>

By following this approach, you can easily organize your routes without cluttering up your main file. Each route group can be managed separately, making code maintenance and readability much easier.
