Auth JWT Example

This example demonstrates a boilerplate setup for a Go Fiber application that uses JWT for authentication.

Description

This project provides a starting point for building a web application with user authentication using JWT. It leverages Fiber for the web framework and GORM for ORM.

Requirements

• Go 1.18 or higher
• Git

Setup

1. Clone the repository:

   git clone https://github.com/gofiber/recipes.git
   cd recipes/auth-jwt

2. Set the environment variables in a .env file:

   DB_PORT=5432
   DB_USER=example_user
   DB_PASSWORD=example_password
   DB_NAME=example_db
   SECRET=example_secret

3. Install the dependencies:

   go mod download

4. Run the application:

   go run main.go

The API should now be running on http://localhost:3000.

Database Management

You can manage the database via psql with the following command:

psql -U <DB_USER> -d <DB_NAME> -h localhost -p <DB_PORT>

Replace <DB_USER>, <DB_NAME>, and <DB_PORT> with the values from your .env file.

API Endpoints

The following endpoints are available in the API:

• POST /api/auth/register: Register a new user.
• POST /api/auth/login: Authenticate a user and return a JWT.
• GET /api/user/:id: Get a user (requires a valid JWT).
• POST /api/user: Create a new user.
• PATCH /api/user/:id: Update a user (requires a valid JWT).
• DELETE /api/user/:id: Delete a user (requires a valid JWT).
• GET /api/product: Get all products.
• GET /api/product/:id: Get a product.
• POST /api/product: Create a new product (requires a valid JWT).
• DELETE /api/product/:id: Delete a product (requires a valid JWT).

Example Usage

1. Register a new user:

   curl -X POST http://localhost:3000/api/auth/register -d '{"username":"testuser", "password":"testpassword", "email":"[email protected]"}' -H "Content-Type: application/json"

2. Login to get a JWT:

   curl -X POST http://localhost:3000/api/auth/login -d '{"username":"testuser", "password":"testpassword"}' -H "Content-Type: application/json"

3. Access a protected route:

   curl -H "Authorization: Bearer <JWT>" http://localhost:3000/api/user/1

Replace <JWT> with the token received from the login endpoint.

Conclusion

This example provides a basic setup for a Go Fiber application with JWT authentication. It can be extended and customized further to fit the needs of more complex applications.
