Pull request overview
Adds a dedicated frontend CI pipeline and introduces baseline frontend tooling/scaffolding so frontend changes get automated lint/typecheck/build/test validation in this repo.
Changes:
- Added
.github/workflows/frontend-ci.ymlto run ESLint, TypeScript checks, Vite build, Vitest tests, and coverage uploads (path-filtered tofrontend/**). - Introduced initial Vite + React + Tailwind + Vitest setup with a starter
Appcomponent and tests. - Updated project documentation (README badges/CI sections and CONTRIBUTING) to reflect the new frontend CI workflow and updated CI guidance.

frontend/package.json sets "type": "module", so these config files run as ESM where __dirname is not defined. Using path.resolve(__dirname, './src') will throw at runtime and break vite build / dev server. Use an import.meta.url-based resolution (e.g., fileURLToPath(new URL('./src', import.meta.url))) or equivalent instead of __dirname.

frontend/package.json sets "type": "module", so this config runs as ESM and __dirname is not defined. path.resolve(__dirname, './src') will throw and prevent Vitest from starting (including in CI). Switch the alias to an import.meta.url-based path resolution (e.g., fileURLToPath(new URL('./src', import.meta.url))).

The workflow runs the test suite twice (npm test -- --run and then npm run test:coverage -- --run). This roughly doubles CI time and can undermine the “under 5 minutes” goal. Consider running only the coverage command (which already executes tests) and using its exit code as the test gate, or generate coverage in the primary test run.

This workflow runs TypeScript checking twice: npx tsc --noEmit here, and npm run build (per frontend/package.json) also invokes tsc before vite build. Consider either (a) changing the workflow build step to run vite build directly, or (b) dropping the standalone tsc --noEmit step and relying on the build script, to avoid duplicated work and reduce CI time.

In other workflows (e.g. ci.yml), third-party actions like Codecov and Codacy coverage reporter are pinned to a specific commit SHA. Here they’re referenced by floating tags (codecov/codecov-action@v4, codacy/codacy-coverage-reporter-action@v1), which increases supply-chain risk. Consider pinning these to known-good SHAs (optionally with a comment noting the upstream version).

Frontend CI Workflow - Implementation Complete ✅
Summary
Successfully implemented a comprehensive frontend CI workflow that validates code quality, runs tests, and uploads coverage reports. The workflow is optimized for speed and only runs when frontend files change.
