A simple Protobuf gRPC authentication microservice. The service is very simple, and intuitive. The project was started in a weekend, so it has a lot of room for improvement.

The microservice uses Postgresql for storage of the information.

Currently, there are four routes:

• Register - gets a user model and registers to the Database.
• Login - gets email and password and verifies them. Generates JWT token accordingly.
• RefreshToken - gets a token and refreshes it if the token is valid.
• ValidToken - checks whether the JWT token is valid or not.

A simple schema of a user:

• Email: string, unique
• Nickname: string unique,
• HashedPassword: string

The rest is a Gorm model

Refer to the docker-compose.yaml. Simply put docker-compose up in the closest shell to your home and the microservice will be up and running. For autocomplete, I have a script for generating the protobuf, you can change the settings for the db connection so it will take default params for developing outside of Docker.

Now I have a basic auth microservice that will verify in a blazing fast speed the authentication needed. This is built as a module that can be integrated into any Docker-like environment.

Just remember - you can use snippets from here to understand what is going on, but do not use it for production.
