Optimize GitHub Actions frontend-ci workflow for 2-minute target

Summary

This PR optimizes the frontend-ci GitHub Actions workflow to reduce execution time from 5m 3s to under 2 minutes by addressing the main performance bottlenecks.

Key Optimizations

1. Job Parallelization 🚀

  • Split frontend-ci into separate frontend-test-unit and frontend-test-integration jobs
  • Unit tests run without Supabase dependency: --filter='!@liam-hq/app'
  • Integration tests run with PostgreSQL service container: --filter='@liam-hq/app'

2. Supabase Startup Optimization ⚡

  • Before: Full Supabase startup (~3 minutes)
  • After: PostgreSQL service container with health checks (~30 seconds)
  • Uses supabase/postgres:15.1.1.78 image with proper health monitoring

3. Turbo Cache Implementation 📦

  • Added Turbo cache configuration to all jobs
  • Cache key: ${{ runner.os }}-turbo-${{ hashFiles('**/pnpm-lock.yaml') }}
  • Enabled test caching in turbo.json with "cache": true

4. pnpm Installation Optimization 🔧

  • Added --ignore-scripts flag to skip unnecessary post-install scripts
  • Maintains --frozen-lockfile and --prefer-offline for reliability

5. Reduced Timeouts ⏱️

  • Reduced job timeouts from 15 minutes to 5 minutes
  • Lint job timeout reduced to 5 minutes

Expected Performance Improvements

Optimization Time Saved Details
Supabase → PostgreSQL service 2-3 minutes Eliminates full Supabase startup
Turbo cache 30-60 seconds Caches build artifacts and test results
pnpm --ignore-scripts 10-15 seconds Skips unnecessary post-install scripts
Job parallelization 30-45 seconds Unit and integration tests run in parallel
Total Expected 3-4.5 minutes Target: Under 2 minutes

Files Changed

  • .github/workflows/frontend-ci.yml - Main workflow optimization
  • .github/actions/pnpm-setup/action.yml - pnpm installation optimization
  • turbo.json - Enable test caching

Testing Strategy

  • All existing tests continue to run with the same coverage
  • PostgreSQL service container provides the same database functionality
  • Turbo cache ensures consistent build behavior
  • Job parallelization maintains test isolation
