Automation & data

Built in January 2026

The WhatsApp connection drops on every restart

QR pairing, credentials kept on disk, and messages relayed to the agents.

An animated diagram, demo data: an agent sends a message through the gateway, with QR pairing once, the session kept on disk, the proxy and bounded reconnection.

The problem

The agents needed a WhatsApp connection that survives restarts and does not get the server’s IP banned.

What I built

A small TypeScript service on WhatsApp Web (Baileys, unofficial): QR pairing, credentials persisted per session, one SOCKS or HTTPS proxy for the service, and reconnection that stops on a real logout.

Technical details

SOCKS or HTTPS proxy, set by one variable
No infinite reconnect loop on a logged-out account
848 lines, single purpose

Stack

TypeScript strict
Node.js
Express
Baileys
Supabase

The result

One service serves two products with different databases, without duplicated code.
