Send messages with Whatsapp using Node & Express free in less than 5 minutes

If you need WhatsApp node implementation for MERN or MEAN stack or just for creating a bot. WhatsApp-node-api is a wrapper for whatsapp-web.js it allows sending messages with very little setup and the process is straightforward.

I broke down the process into three steps;

1. Install & Setup — setting up whatsapp-node-api api.js server
2. Authenticate — authentication of WhatsApp desktop
3. Send ‘Hello World’ message
