Postgrest-auth

This project is inspired of postgrest-auth. But it's writting in golang, it's actively maintained, and email are using the hermes library to be prettier.

The goal of this project is to provide the whole authentication features for a postgrest-prowered API. It must be deployed alongside your API and share the same jwt secret with your postgrest instance.

This service automatically creates a schema named "auth" and roles defined used environment variables. It provides you an helper fonction auth.current_user_id() that you can for instance use in your POLICES:

CREATE POLICY questions_update ON questions FOR UPDATE
    USING (user_id = auth.current_user_id())
    WITH CHECK (user_id = auth.current_user_id());
