This microservice provides features related to books in a library. This service is written in Typescript and uses the NestJs application framework. Package management is done with Node.js. Data storage is in MySQL, with Prisma providing ORM features. The unit tests use Jest.

This service can be run locally with a standalone MySQL installation. A script is provided to handle creating the database schema, before starting the service. Create '.env' to configure your local installation.

• npm run startup

After the initial startup and schema deployment, the service can be started with

• npm run start

Alternately, the service can be run in a Docker container alongside a containerized MySQL instance. With Docker installed and the engine started, use:

• docker compose up

This will pull images with Node, install dependencies, build and copy relevant files, deploy the DB schema and start the service.

Service will be available on localhost, port 3000 via either method.

• http://localhost:3000/health

The Library controller and service are covered by unit tests. The tests use mocking to isolate the code under test as appropriate. Tests can be executed with:
