The gin-cors package can be used in every Gin project and configure the cors behaviour of your application.

After installing and setting up Go you can create yor first project with gin.

In your main go file create a basic gin http server with the gin-cors middleware package

package main

import (
  "net/http"

  "github.com/gin-gonic/gin"
  cors "github.com/OnlyNico43/gin-cors/v2"
)

func main() {
  r := gin.Default()

  r.Use(cors.Middleware(cors.DefaultConfig()))

  r.GET("/ping", func(c *gin.Context) {
    c.String(http.StatusOK, "pong")
  })

  r.Run(":8080")
}

Done, now your application is equipped with a basic cors configuration

You can either use the default configuration or decide to use your own values in the Config object.
