Build a Chat Messenger App like WhatsApp
Design a full-featured real-time chat app that supports private messages, group chats, media sharing, presence tracking, and instant push notifications.Real-time messaging apps are complex but highly rewarding projects. You’ll learn about sockets, backend message queues, user presence, media uploads, chat UI/UX, and more—making this an ideal challenge for intermediate to advanced app development.
Let users send direct messages, create groups, share media, and get real-time updates. Use WebSockets or Socket.io for real-time communication and push notifications for alerts.
1-on-1 Messaging
Enable users to send and receive messages instantly with delivery/read indicators.
Group Chats
Allow users to create and manage group conversations with multiple participants.
Media Sharing (Images, Files)
Support file, image, and video sharing with previews and cloud storage.
User Presence & Notifications
Show online/offline status and send push notifications for new messages.
Messages are sent and received over WebSockets in real time. All chat data is stored in a backend database, and media is hosted using a secure cloud platform. User presence is tracked and reflected in the UI with notifications.
- Users sign up, create a profile, and connect with contacts.
- Start 1-on-1 or group chats with real-time messaging.
- Send emojis, images, files, and voice notes.
- Messages sync in real time across devices using sockets.
- Users receive push notifications for new messages and mentions.
Frontend
React Native for mobile; use GiftedChat or custom chat UI components for conversation threads.
Backend
Node.js with Express and Socket.io for real-time message handling, storage, and broadcasting.
Database
MongoDB with Mongoose for message logs, user info, and group metadata.
Other Tools
Firebase Cloud Messaging for push notifications, Cloudinary for file uploads, JWT for authentication.
1. Set Up User Auth and Contacts
Build a secure registration/login system and allow users to add/search contacts.

4. Media Upload and Storage
Enable sending files/images and host them on Cloudinary or Firebase.
5. Push Notifications & Presence Updates
Use FCM to push alerts and implement online/offline presence indicators.
