Go JWT Authentication Project

Overview

This project demonstrates how to implement JWT (JSON Web Token) authentication in a Go (Golang) application. It provides basic APIs for user registration, login, and protected routes accessible only with a valid JWT.

Features

• User Registration: Allows users to register with a username and password.
• User Login: Validates user credentials and returns a signed JWT.
• Protected Routes: Routes that can only be accessed with a valid JWT.
• JWT Middleware: Middleware to verify JWT tokens on protected routes.

Tech Stack

• Go: Main programming language.
• JWT (JSON Web Tokens): For stateless authentication.
• GIN: HTTP request router for handling routes.
• github.com/dgrijalva/jwt-go: JWT library for creating and verifying tokens.
• MongoDB: For persistent user storage.

Setup

Prerequisites

Ensure you have the following installed:

• Go (v1.16 or higher)
• A database (e.g., PostgreSQL/MySQL/SQLite,MongoDB) for storing user data.

Installation

1. Clone the repository:

   git clone https://github.com/ABHI2598/Jwt-Authentication-Go.git
   cd Jwt-Authentication-Go
   

2. Install dependencies:

   go mod init main.go
   go mod tidy
   

3. Set up environment variables: Create a .env file in the project root to store sensitive information like JWT secrets and MongoDB connection details.

4. Run the application:

   go run main.go

5. The API will now be accessible at respective port defined in .env file.
