A simple authentication API.

What you can do:

  • add new users
  • sign in with your user when is already registered
  • get a JWT if authentication is successful

Running Locally

git clone https://github.com/Edmartt/go-authentication-api

or ssh instead:

cd go-authentication-api
go mod tidy
go run main.go



This is actually set for using with SQLite for simplicity, but you can switch this database manager for postgres if needed. Just go to internal/users/data/repository.go and change the line 10 typing Postgres. If you use postgres, remember to set the .env.example values according to your setup. Note that I left the : as part of HTTP_PORT env var value, so if you need to change this port just delete the numbers.

You can use any client you want. I’m using curl:

curl -i -X POST -H "Content-Type: application/json" -d '{"username":"shinigami", "password":"12345678"}' http://localhost:8081/api/v1/users/signup

This is my response:

HTTP/1.1 201 Created
Content-Type: application/json

Once the user is created you can sign in:

curl -i -X POST -H "Content-Type: application/json" -d '{"username":"shinigami", "password":"12345678"}' http://localhost:8081/api/v1/users/login

This is my response:

HTTP/1.1 200 OK
Content-Type: application/json
