Building chat apps with react native

Creating a real-time chat application using React Native and Firebase is an excellent way to build a cross-platform mobile app with robust backend services. React Native allows developers to write a single codebase for both iOS and Android, while Firebase, Google’s Backend-as-a-Service (BaaS), provides real-time database capabilities, authentication, and cloud storage without managing servers.

This step-by-step guide will walk you through building a simple chat app in 2025, where users can sign in with email/password, send messages, and see real-time updates, using the latest tools and packages.
