How do I set up a web framework in Go?

To set up a web framework in Go, you can start by choosing a framework like Gin or Echo. Do you have a preference?

I think I want to use Gin. What are the steps?

Great choice! First, install Gin using go get -u github.com/gin-gonic/gin. Then, create a simple server with the following code:

package main

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

func main() {
    r := gin.Default()
    r.GET("/", func(c *gin.Context) {
        c.JSON(200, gin.H{"message": "Hello, World!"})
    })
    r.Run() // listen and serve on 0.0.0.0:8080
}

What do I do after I run the server?

After running the server, you can open your browser and go to http://localhost:8080 to see the "Hello, World!" message.
