Golang Authentication Template

This repository provides a simple example of how to implement authentication in a Golang application. It uses a PostgreSQL database to store user information, and JWT authentication to authenticate users.

Getting started

To get started, clone this repository and install the dependencies:

git clone https://github.com/fahmisalman/Go-auth
cd go-auth
go mod init
go mod tidy

Once the dependencies are installed, you can start the application:

go run main.go

The application will listen on port 8080 by default. You can access the application in your web browser at http://localhost:8080/

Authentication

To authenticate, you can send a POST request to the /auth/login endpoint with the following JSON body:

{
  "username": "user@example.com",
  "password": "password"
}

Use code with caution. Learn more If the authentication is successful, the server will return a JSON Web Token (JWT) in the Authorization header of the response. You can then include this JWT in the Authorization header of subsequent requests to authenticate yourself to the server.

Registering a new user

To register a new user, you can send a POST request to the /auth/register endpoint with the following JSON body:

{
  "name": "John Doe",
  "email": "john.doe@example.com",
  "username": "john.doe",
  "password": "password"
}

Use code with caution. Learn more If the registration is successful, the server will return a JSON response with the following fields:

id: The ID of the new user name: The name of the new user email: The email address of the new user Example usage

# Login
curl -X POST \
  -H "Content-Type: application/json" \
  -d '{
    "username": "user@example.com",
    "password": "password"
  }' \
  http://localhost:8080/auth/login

# Register a new user
curl -X POST \
  -H "Content-Type: application/json" \
  -d '{
    "name": "John Doe",
    "email": "john.doe@example.com",
    "username": "john.doe",
    "password": "password"
  }' \
  http://localhost:8080/auth/register

Deployment

To deploy this application, you can use a variety of different tools and services. For example, you could deploy the application to a cloud platform such as Heroku or AWS Elastic Beanstalk. You could also deploy the application to a self-managed server using a tool such as Docker or Kubernetes.

Conclusion

This repository provides a simple example of how to implement authentication in a Golang application. It is a good starting point for developers who are new to authentication, or who are looking to implement a specific authentication method in their application.
