This repository contains a sample project for implementing JWT token authentication in a Golang and MongoDB backend. The project uses middlewares for verification and proper validation of login and register data.

• Golang
• MongoDB
• Postman or any similar tool for API testing

1. Clone the repository

2. Navigate to the project directory

3. Run go mod download to download the required dependencies

4. Create a .env file and add the following variables:

   PORT=<port_number>
   MONGO_URI=<mongodb_uri>
   JWT_SECRET=<jwt_secret_key>
   

5. Run the project using go run main.go

• POST Request

• Endpoint - http://localhost:<port_number>/user/register

• Request Body - JSON

  {
  "name": "<user_name>",
  "email": "<user_email>",
  "password": "<user_password>"
  }
  

• Response - JSON

  {
  "message": "User registered successfully!"
  }
  

• POST Request

• Endpoint - http://localhost:<port_number>/user/login

• Request Body - JSON

  {
  "email": "<user_email>",
  "password": "<user_password>"
  }
  

• Response - JSON

  {
  "token": "<jwt_token>"
  }
  

• GET Request
• Endpoint - http://localhost:<port_number>/check/get/:id
• Headers -
  • Authorization: Bearer <jwt_token>
• Response - JSON

  {
  "message": "User authorized successfully!",
  "id": "<user_id>"
  }
  

The project uses the following middlewares for JWT token verification and proper validation of login and register data:

1. validateRegisterData - Validates the user registration data before creating a new user.
2. validateLoginData - Validates the user login data before generating a new JWT token.
3. verifyToken - Verifies the JWT token sent in the request headers before granting access to the protected routes.

This project provides a basic setup for implementing JWT token authentication in a Golang and MongoDB backend. You can customize and extend the project based on your specific requirements.
