Summary by CodeRabbit

• Tests
  • Unit tests now run in CI on every change; deployments are gated on successful test runs. Test scripts updated so coverage commands tolerate absent tests.
• API
  • Trip-stop responses now include a scheduled arrival field.
• Reliability
  • Real-time and static feed handling improved for more robust data ingestion and alert/vehicle parsing.
• Chores
  • Tooling updated (TypeScript/linters/configs) to modernize the build environment.

📝 Walkthrough

Walkthrough

This PR adds a new unit CI job to the GitHub Actions workflow. The job checks out code, configures Node 20, installs dependencies for both the root and frontend packages, and runs npm run test:unit. The deploy job is updated to depend on this new job, ensuring unit tests pass before deployment.

Changes

CI Unit Testing Integration

Layer / File(s)	Summary
Unit test CI job definition .github/workflows/ci.yml	New unit job runs on ubuntu-latest, sets up Node 20 with npm cache, installs root and frontend dependencies, and executes npm run test:unit. The deploy job is updated to wait for unit completion via needs.

Poem

A rabbit hops through workflows bright,
Where tests now run with all their might,
Before the deploy takes flight so high,
Unit checks ensure things fly right by! 🐰✨

❌ Failed checks (1 warning, 1 inconclusive)

Check name	Status	Explanation	Resolution
Docstring Coverage	⚠️ Warning	Docstring coverage is 0.00% which is insufficient. The required threshold is 80.00%.	Write docstrings for the functions missing them to satisfy the coverage threshold.
Title check	❓ Inconclusive	The title 'fixed unit test workflow' is vague and overly broad. While the PR does include CI workflow changes (adding a unit test job), it encompasses far more extensive modifications including TypeScript configuration updates across multiple services, dependency version upgrades, ESLint setup, and refactoring of service implementations.	Consider using a more descriptive title that reflects the broader scope, such as 'Update TypeScript config and add unit test CI workflow' or 'Migrate to node16 modules and add unit testing pipeline'.
