GoAuth - An authentication app which handles register & login via RESTful API

I made this project while learning golang.This backend app is my first project, that I made using GoFiber(A backend framework for Go).

Requirement

• Go
• PostgreSQL

Starting the backend server

Setting up files:

    git clone https://github.com/ryszhio/goauth.git
    cd goauth
    mv example.env .env  # Edit your env file to setup database. (Make sure to have postgres and access to database.)

Running Server

    go run main.go

OR

    go build .
    ./goauth

End Points

1. Register

    POST /api/auth/register

2. Login

    POST /api/auth/login

3. Default

    GET /
    POST /

Just returns simple message with goauth working..

How to send request ?

1. Register

    POST /api/auth/register
    
    Body:

    {
        "username": "",
        "display_name": "",
        "password": "",
        "email": "",
        "phone_number": ""
    }

Fill the fields properly & Send Request.

Status Response:

1. 400 - Bad Request

• Invalid JSON request
• Invalid email
• Invalid username
• Email already taken
• Username already taken

2. 500 - Internal Server Error

• Failed to check if email already exists
• Failed to check if username already exists
• If failed to hash the password.
• Failed to write user into the database

3. 201 - Status Created

• If user is successfully registered.

2. Login

    POST /api/auth/register

    Body:

    {
        "identity": "", 
        "password": ""
    }

Identity field should either contain email or username Fill the field properly.

Status Response:

1. 400 - Bad Request

• Invalid JSON request

2. 500 - Internal Server Error

• Failed to retreive info from database
• Failed to generate JWT Token (JWT are not implemented yet. It just generates token for now)

3. 401 - Status Unauthorized

• Entered identity or password doesn't match

4. 200 - OK

• Returns a JWT Token for session based authentication. (JWT are not implemented yet. It just generates token for now)

Packages Used

• GoFiber (The core backend framework)
• GORM (For Object-Relation-Mapping & also postgres driver)
• godotenv (To load environment variables from .env file)

Future Plans

• Implement Middlewares for protecting routes.
• Implement JWT for session based authentication.
