Development

If you use VSCode, install plugin for Prisma: https://marketplace.visualstudio.com/items?itemName=Prisma.prisma

Integration tests

GraphQL queries and mutations are using Postgres for an integration test validation. So make sure you have the db up and running.

yarn postgres:start
yarn test

Authentication & Authorization

The Gateway authenticates the user (TODO) and send proper headers to the service. The service uses graphql-shield to verify permissions.
