Migration from Go Gin to Go Fiber

[rabilrbl]

As part of our ongoing efforts to improve the performance and scalability of our Go web application, we have decided to migrate from Go Gin to Go Fiber. Go Fiber is a lightweight and fast web framework that is compatible with the Go standard library, offers similar features to Go Gin, and provides additional optimizations.

Proposed Solution

To complete this migration, we need to update our codebase and replace Go Gin-specific functionality with equivalent or similar features in Go Fiber. This will involve making changes to our routing, middleware, request handling, and response handling code.

Tasks

• Research the differences between Go Gin and Go Fiber and identify the corresponding changes required in our codebase.
• Update the routing logic to use Go Fiber's routing syntax and ensure that all existing routes are correctly migrated.
• Review the middleware stack and update it to use Go Fiber's middleware functionality, ensuring that all middleware functions are properly integrated.
• Modify the request and response handling code to reflect the changes in the Go Fiber API.
• Update any dependencies or third-party libraries that rely on Go Gin-specific functionality to ensure compatibility with Go Fiber.

Additional Information

• Our codebase is written in Go and is currently using Go Gin version v1.9.1
• Go Fiber version v2

Example Code Snippet:

package main

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

func main() {
	router := gin.Default()
	router.GET("/hello", func(c *gin.Context) {
		c.JSON(200, gin.H{
			"message": "Hello, World!",
		})
	})
	router.Run(":8080")
}

Example Code Snippet (Updated with Go Fiber):

package main

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

func main() {
	app := fiber.New()
	app.Get("/hello", func(c *fiber.Ctx) error {
		return c.JSON(fiber.Map{
			"message": "Hello, World!",
		})
	})
	log.Fatal(app.Listen(":8080"))
}
