# Act Integration - Complete Optimization

**Status:** ✅ **FULLY OPTIMIZED**

**Date:** December 25, 2025

---

## 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](.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:**
```bash
# Automatically uses catthehacker/ubuntu:act-latest
npm run act
```

### 2. ✅ **Secrets Management Template**
- **File:** [.secrets.example](.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:**
```bash
cp .secrets.example .secrets
# Edit .secrets with your GitHub token
act --secret-file .secrets
```

### 3. ✅ **Expanded NPM Scripts** (8 Total)
- **File:** [package.json](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:**
```bash
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](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](scripts/pre-commit.hook)
- **What:** Optional validation before commits
- **Setup:**
```bash
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](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:**
```bash
# 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](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**

## Quick Start (For New Users)

### First Time Setup (5 minutes)

```bash
# 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

```bash
# 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

```bash
# 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

```bash
# 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

```bash
# 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

```bash
# 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)
   ```bash
   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)
   ```bash
   npm run act:diagnose
   ```

3. **Check Docker image cache**
   ```bash
   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**
   ```bash
   # Logs saved to /tmp/act-logs/ automatically
   ls -lh /tmp/act-logs/
   ```

2. **Use verbose mode when stuck**
   ```bash
   npm run act -- --verbose
   ```

3. **Try dry-run first**
   ```bash
   act -n -j lint  # Preview without executing
   ```
