JWT Authentication with Go and Chi

A simple Go API that demonstrates JWT authentication using the Chi router and the jwt-go library for secure token handling.

Features

• JWT Authentication: Protects API routes with JWT-based authentication.
• Middleware: Utilizes Chi middleware for easy route handling and token verification.
• Modular Code: Organized for readability and scalability.

Getting Started

Prerequisites

• Go (version 1.16 or higher is recommended)
• Git

Installation

1. Clone the repository

   git clone https://github.com/manimovassagh/jwt-go-chi.git
   cd jwt-go-chi

2. Install dependencies

   go mod download

3. Run the server

   go run main.go

Environment Variables

Define the following environment variables in a .env file or export them in your shell:

• JWT_SECRET: Secret key for signing JWT tokens.

Example .env:

JWT_SECRET=your_secret_key

Usage

• Generate a Token: Access the /login endpoint with user credentials to receive a JWT token.
• Access Protected Routes: Use the JWT token in the Authorization header as Bearer <token> to access protected routes like /protected.

Example Requests

1. Login:

   POST /login
   Content-Type: application/json
   {
       "username": "your_username",
       "password": "your_password"

2. Access Protected Route:

   GET /protected
   Authorization: Bearer <your_jwt_token>
