WPPConnect Hugging Face Deployment Status

Status: SUCCESSFUL

The codebase has been successfully adapted for deployment on Hugging Face Spaces with a dual-service architecture.

Architecture Overview

1. Node.js Backend: Runs WPPConnect (WhatsApp Web automation) and exposes a local REST API on port 3000.
2. Python Frontend: A Gradio application running on port 7860 (mandatory HF port) that provides a user-friendly interface.

Key Features Implemented

• Gradio Control Panel:
  • Live status monitoring.
  • Interactive QR code display for easy authentication.
  • Tabs for sending text messages and polls.
  • Log streaming for debugging within the UI.
  • Browser screenshot tab for visual debugging of Puppeteer.
• Resilient Backend:
  • Background initialization to satisfy HF health checks.
  • DNS bypass strategy (manual IP resolution for web.whatsapp.com) to handle restricted network environments.
  • Automatic token cleanup to prevent browser lock issues.
• Containerized Environment:
  • Multi-runtime Dockerfile (Node.js + Python + Chrome).
  • Optimized Puppeteer flags for stable container operation.

Access and Usage

• URL: https://huggingface.co/spaces/AUXteam/wppconnect-api
• Frontend: Accessible via the main URL.
• API Endpoints:
  • /health: Check system status.
  • /api-docs: View available endpoints.
  • /send-poll: POST endpoint for automation.

Notes for Future Deployment

• If the space is stuck on "Preparing", check the run logs. DNS resolution for WhatsApp can sometimes be delayed in new containers.
• Persistence is currently ephemeral; the QR code must be scanned on each new deployment/restart.
