● I have access to the MCP Puppeteer tool, which gives me browser automation capabilities. Here's what I can do with it:
Navigation & Viewing:
- puppeteer_navigate: Navigate to any URL
- puppeteer_screenshot: Take screenshots of pages or specific elements
Interaction:
- puppeteer_click: Click buttons, links, or elements
- puppeteer_fill: Fill in text input fields
- puppeteer_select: Select options from dropdown menus
- puppeteer_hover: Hover over elements
Advanced:
- puppeteer_evaluate: Execute JavaScript in the browser console
For GitLab, I could use Puppeteer to:
- Navigate to your GitLab repository (gitlab.com or self-hosted)
- View issues, merge requests, branches, etc.
- Create merge requests automatically
- Click buttons to merge PRs, approve reviews, etc.
- Fill in forms for creating issues or PRs
- Take screenshots to verify status
- Execute JS to interact with GitLab's web interface
Use cases for your project:
- Create and merge MRs directly from the web interface
- View repository status, branches, or pipeline results
- Automate repetitive GitLab web tasks
- Verify changes were applied correctly (by taking screenshots)
Would you like me to use Puppeteer to help with something specific on your GitLab repository?

● Implementation Complete ✓
I've successfully implemented the Node.js backend for Circuits.CC. Here's what was created:
Files Created
1. nodejs/pcbdb-server.js - Main Express server with:
- Automatic database and table initialization on startup
- Two main API modes:
- GET /api/pcb?id=0 - Returns current board state (all latest cell values)
- GET /api/pcb?id=N&col=C&row=R&sym=S - Inserts action and returns updates since id=N
- Health check endpoint: GET /api/health
- Manual setup endpoint: GET /api/setup
- Proper error handling and graceful shutdown
2. nodejs/package.json - Dependencies configured:
- express (HTTP framework)
- mysql2 (with promises for async/await)
- dotenv (configuration management)
- nodemon (development auto-reload)
3. nodejs/.env.example - Configuration template for easy setup
4. nodejs/.env - Pre-configured with your MySQL root credentials
5. nodejs/README-pcbdb.md - Comprehensive documentation including:
- Installation steps
- API endpoint reference
- Testing examples
- Frontend integration options
- Troubleshooting guide
API Testing Results
All endpoints tested and working:
Test 1: Empty board (id=0)
→ Returns: (empty)
Test 2: Insert component (id=1, col=5, row=10, sym=65)
→ Returns: 5,10,65,2 (the new record)
Test 3: Insert component (id=1, col=6, row=11, sym=66)
→ Returns: 5,10,65,2 \n 6,11,66,3 (all records since id=1)
Test 4: Get current board state (id=0)
→ Returns: 5,10,65,2 \n 6,11,66,3 (all current cells)
Test 5: Poll for updates since id=2
→ Returns: 6,11,66,3 \n 7,12,67,4 (updates since id=2)
Key Features
- ✅ Automatic initialization - Creates database and tables on first run
- ✅ Security - Uses parameterized queries (prevents SQL injection)
- ✅ Connection pooling - 10 concurrent connections for efficiency
- ✅ IP tracking - Records client IP for each action
- ✅ Exact API compatibility - Matches PHP output format (CSV)
- ✅ Production-ready - Proper error handling and graceful shutdown
To Use
cd nodejs
npm start
The server will run on http://localhost:3000 with the API at /api/pcb
Next Steps
To integrate with the frontend, update www/sandbox.html line 48:
var db = 'http://localhost:3000/api/pcb?';
Or use a reverse proxy to maintain the existing URL structure.
