Day 14 of 14 40 minPlanningBuildingTesting
Build a complete, tested REST API for notes that uses everything from the course. Plan the modules, store notes in a JSON file with safe writes, validate input, route requests, log as JSON, and test it all with node:test.
By the end of today you can
- Plan an API as small modules with clear jobs
- Store data in a JSON file safely, with atomic writes and a write queue
- Build routes with validation and consistent errors
- Inject dependencies so the app is easy to test
- Test the API end to end with node:test and fetch
