The Postgres DB runs in a docker container. To Start the DB, run sh start-database.sh. You need to have docker installed on your machine. You may find a GUI application like tableplus useful to connect to the DB and be able to easily interact with it, but this should not be essential.
Once you have created the DB, you need to duplicate the .env.example fil, rename to .env and fill in your values.
Establish connection with the Postres server. Create "yamaha" database.
Run bun db:push
There is a script located at src/server/db/seed.ts that you can run by using the command bun run ./src/server/db/seed.ts from the root of the project. This should connect to the DB and insert some data. The script is not complete yet, so not all entities have sample data. But there is enough in there to get started.
Run bun db:studio to see a really intuitive and helpful UI to allow you to quickly interact with the DB.
Run bun dev to start the app. There should be a URL outputted in the terminal that you can visit to see the app running.
To run the unit tests, run bun test from the root of the project. Ensure you have run bun i before running the tests.
