Authentication with gin-gonic && gah for golang

I have developed a nice rest api at the weekend with Golang.

What is important here is to log in and register using golang in a simple way.

Gin Auth Handlers - github

I'm very excited and let's get started.

First let's create a golang project:

$ mkdir project
$ cd project
$ touch main.go

Let's install the gin and gah(Gin Auth Handlers) packages.

$ go get -u github.com/gin-gonic/gin
$ go get -u github.com/yasaricli/gah

Open our main.go file as follows

package main

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

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

  api := router.Group("/api")
  {
    api.POST("/login", gah.LoginHandler)
    api.POST("/register", gah.RegisterHandler)
  }

  router.Run(":3000")
}

Let's set environment variables.

export MONGO_URL=mongodb://127.0.0.1:27017 # MongoDB server URL.
export MONGO_DATABASE=project_db # MongoDB Project db name
export MONGO_COLLECTION=users # Collection to register all users

Let's start api with run command.

go run main.go
