Health checks

System for running simple HTTP health checks.

This knocks out a fairly specific set of criteria though leaves the door open for extensibility and refactoring. New checks can be added in src/health.ts.

There is an approach with a fully evented runner system available in the commit history which totally decouples job run time from the runner. Though it was abandoned in favor of simpler.

How to 💻

1. Verify Node.js >= 18 is installed: node --version
   • If something >= 18.x.x is printed, continue
   • If not, install Node.js
     • I recommend using fnm but do whatever works for you
2. Clone project
3. Run npm clean-install
4. Run npm start
   • You can also run it directly with npm run build && node dist/cli.js
   • Set DEBUG=health-check:runner environment variable for more context, if you'd like
5. Run the tests: npm test
