JD-107 Hello PR

[IstiN]

Issues/Notes

All acceptance criteria implemented successfully. No blocking issues encountered.

Assumption: The ticket request "create Hello changes in web index" was interpreted as enhancing the web landing page with a dynamic "Hello" greeting driven by a testable JavaScript module, replacing the static h1 with a greeting sourced from a dedicated module.

Approach

1. Greeting module: Created web/js/greeting.js as the single source of truth for the "Hello" greeting and page title. Exports getGreeting(), getPageTitle(), and attachToGlobal().

2. Browser script: Added web/scripts/build-greeting-browser.js to generate web/js/greeting-browser.js from the greeting module. The browser script is an IIFE that attaches getGreeting and getPageTitle to window.

3. index.html: Updated to load greeting-browser.js and use getPageTitle() to set the h1 and document title dynamically. The greeting is now driven by the module instead of hardcoded HTML.

4. Test setup: Introduced Jest in web/ with package.json, jest.config.js, and 100% coverage thresholds. The pretest script runs the build so greeting-browser.js is regenerated before tests.

5. CI workflow: Added .github/workflows/unit-tests.yml to run unit tests on pull requests that touch web/ or the workflow file. Updated deploy-pages.yml to run the build step before deploying so the browser script is always up to date.

Test Coverage

100% coverage on all new and modified code:

• greeting.js: getGreeting, getPageTitle, attachToGlobal – happy path and integration
• build-greeting-browser.js: Output generation and file write
• index.html integration: Script reference, getPageTitle usage, greeting-title element
• greeting-browser.js sync: Values match greeting module

10 tests total, all passing.

CI/CD

• Unit test workflow: Created .github/workflows/unit-tests.yml. Triggers on pull_request to main when web/** or the workflow file changes. Runs npm ci and npm test in web/.
• Deploy workflow: Updated to run npm run build before deploying so greeting-browser.js is regenerated from the greeting module.
