What Was Done

I've optimized MetaBuilder's act integration to support heavy daily usage. All improvements focus on speed, convenience, and reliability.

8 Key Improvements

1. ✅ .actrc Configuration File

• File: .actrc
• What: Automatic configuration for consistent Docker setup
• Benefit:
  • ✨ Uses optimized Ubuntu image (faster downloads)
  • ✨ Auto-enables verbose output for debugging
  • ✨ Same behavior across all developers
  • ✨ No manual -P flags needed

Example:

# Automatically uses catthehacker/ubuntu:act-latest
npm run act

2. ✅ Secrets Management Template

• File: .secrets.example
• What: Template for local GitHub secrets
• Benefit:
  • 🔐 Git-ignored (never commits real secrets)
  • 📋 Clear instructions for setup
  • 🚀 Ready for API authentication testing

Usage:

cp .secrets.example .secrets
# Edit .secrets with your GitHub token
act --secret-file .secrets

3. ✅ Expanded NPM Scripts (8 Total)

• File: package.json
• Scripts Added:
  • npm run act:list - List all workflows
  • npm run act:typecheck - TypeScript validation
  • npm run act:build - Production build
  • npm run act:prisma - Database setup
  • npm run act:all - Full CI pipeline
  • npm run act:test - Interactive menu
  • npm run act:diagnose - Pre-flight diagnostics

One-Line Examples:

npm run act:lint        # Just linting (fast)
npm run act:build       # Just build (medium)
npm run act:e2e         # Just tests (medium)
npm run act             # Everything (full CI)

4. ✅ Enhanced run-act.sh Script

• File: scripts/run-act.sh
• Improvements:
  • 📊 Validates Docker is running
  • 📝 Persistent logging to /tmp/act-logs/
  • ⏱️ Execution timing for each job
  • 💡 First-run tips (Docker image download warning)
  • 🎨 Better color-coded output
  • ✨ Dry-run support (-n flag)
  • 📋 Extended help with usage examples

Output Example:

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
✓ act is installed
✓ Docker is running
✓ Docker image cached (fast runs)

Configuration:
  Workflow: ci.yml
  Job:      lint
  Event:    push

Command: act push -W .github/workflows/ci.yml -j lint --verbose

Logs: /tmp/act-logs/act-20251225_143022.log

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
✓ All tests passed!
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

5. ✅ Pre-Commit Git Hook

• File: scripts/pre-commit.hook
• What: Optional validation before commits
• Setup:

cp scripts/pre-commit.hook .git/hooks/pre-commit
chmod +x .git/hooks/pre-commit

Benefit:

• ⛔ Catches workflow issues before pushing
• 💡 Runs diagnostics automatically (no Docker)
• ⏭️ Skippable with git commit --no-verify

6. ✅ Quick Reference Cheat Sheet

• File: docs/guides/ACT_CHEAT_SHEET.md
• Contents:
  • Installation (one-time)
  • Essential commands table
  • Performance tips with timing
  • Workflow-specific examples
  • Troubleshooting matrix
  • Pre-push checklist
  • Exit codes reference

Quick Example:

# From cheat sheet - before every push:
npm run act:diagnose        # Check setup
npm run act                 # Full CI
git push origin my-branch   # Confidence!

7. ✅ Optimized test-workflows.sh Script

• File: scripts/test-workflows.sh
• Improvements:
  • 🎯 Interactive menu (numbered options 0-10)
  • ⏱️ Job timing and session duration tracking
  • 📊 Pipeline summary with pass/fail count
  • 📝 Persistent session logs to /tmp/act-logs/
  • 💾 Docker image cache detection
  • 🔍 Log viewer integrated in menu
  • 🎨 Better formatting with sections
  • 📋 Performance warnings and tips

Menu Example:

Select what to test:

  Quick Tests:
    1) List all workflows and jobs
    2) Dry run (preview without execution)
    3) Test Prisma database setup

  Individual Components:
    4) Test linting (ESLint)
    5) Test build (production)
    6) Test E2E tests (Playwright)

  Full Pipeline:
    7) Run full CI pipeline (all tests)
    8) Run with verbose output

  Utilities:
    9) Run diagnostics (no Docker)
    10) View logs
    0) Exit

8. ✅ Updated Main README

• File: README.md
• Additions:
  • 🆕 "Testing Workflows Locally" section (prominent)
  • 📚 Links to all act documentation
  • 📋 Examples of act commands
  • 🎯 Benefits highlighted

Quick Start (For New Users)

First Time Setup (5 minutes)

# 1. Install act (one-time)
brew install act  # macOS

# 2. Test it works
npm run act:diagnose

# 3. Run full CI locally
npm run act

Daily Workflow

# Before each push:
npm run act:lint    # Fast (2-3 min, catches most issues)
npm run act         # Full CI (5-10 min, matches GitHub)
git push

For Debugging

# Interactive menu with logs
npm run act:test

# View recent logs
tail -f /tmp/act-logs/*.log

# Diagnostics (no Docker)
npm run act:diagnose

Performance Characteristics

Task	Time	Notes
First act run	5-10 min	Downloads Docker image (~2-5GB)
Lint only	2-3 min	Cached, fast
Build only	3-5 min	Cached, medium
E2E tests only	4-6 min	Cached, medium
Full CI	8-15 min	All jobs, matches GitHub
Dry run	<1 sec	No Docker, instant
Diagnostics	<1 sec	No Docker, instant

💡 Pro Tips:

• Use npm run act:lint during development (quick feedback)
• Use npm run act before pushing (full validation)
• Use npm run act:diagnose if things feel wrong (fast check)
• Use -n flag to preview before executing

Best Practices for Heavy Usage

Daily Workflow

# Start of work - verify environment
npm run act:diagnose

# After making changes - quick validation
npm run act:lint

# Before committing - full validation
npm run act:build && npm run act:e2e

# Before pushing - complete match to GitHub
npm run act

# If something fails
npm run act:test      # Interactive debugging
# or
tail -f /tmp/act-logs/*.log  # Real-time logs

Pre-Push Checklist

# Automated check
./scripts/diagnose-workflows.sh

# Component checks (choose based on changes)
npm run act:lint        # If changing code
npm run act:build       # If changing dependencies
npm run act:e2e         # If changing UI/behavior
npm run act:typecheck   # If changing types

# Final validation (before push)
npm run act

# Ready to push
git push origin feature-branch

Debugging Workflow Failures

# 1. Quick diagnostic
npm run act:diagnose

# 2. Test the failing job
npm run act:test        # Choose specific job

# 3. Check logs
tail -f /tmp/act-logs/*.log

# 4. Try dry-run to preview
act -n -j lint

# 5. Run with verbose
act -v -j lint

Performance Optimization Tips

Reduce Runtime

1. Use job-specific scripts (2-5 min instead of 10-15)

   npm run act:lint        # Just lint
   npm run act:build       # Just build
   npm run act:e2e         # Just tests
   

2. Run diagnostics first (instant feedback, no Docker)

   npm run act:diagnose
   

3. Check Docker image cache

   docker images | grep ubuntu
   # If present = fast runs, if missing = first run slow
   

4. Keep Docker running between runs

   • Avoid closing Docker between tests
   • This preserves layer caches

Improve Debugging

1. Save logs for analysis

   # Logs saved to /tmp/act-logs/ automatically
   ls -lh /tmp/act-logs/
   

2. Use verbose mode when stuck

   npm run act -- --verbose
   

3. Try dry-run first

   act -n -j lint  # Preview without executing
