BeerJS Cba – Edition #109

BeerJS Córdoba returns with more JavaScript, more beer, and more community learning. The event will take place on Thursday, February 26 at 7:00 PM (ARG), with the online stream starting at 7:30 PM. It will be held at Darwoft’s office (Jujuy 1412, 2nd Floor, Cofico neighborhood) and streamed live.

This edition features two technical talks:

The first session, led by Ron Bachmann, will explore the inner workings of the Virtual DOM. Attendees will build a basic Virtual DOM from scratch to better understand how reconciliation works, why this abstraction exists, its advantages, and when it may not be necessary.

The second talk, presented by Esteban Villalba, focuses on deploying Evolution API for WhatsApp integrations using Node.js. The session will cover real-world lessons, including infrastructure decisions (like choosing a VPS), key configuration steps, and critical connection and session errors that are often missing from official documentation.

The event will also be streamed live online.
