AI BriefingBuilding a Real-Time Chat App with Supabase on Replit
Key point
This explains how to build a real-time chat app using Replit and Supabase, an open-source Firebase alternative.
Details
Firebase is a powerful BaaS (Backend as a Service), but it is closed-source with data under Google's control. Supabase emerged as an open-source alternative to this, offering a similar development experience while maintaining data sovereignty.
Combining the cloud-based IDE Replit with Supabase allows you to build a real-time chat app very quickly.
The main tech stack is as follows:
- Frontend: Vue 3, Tailwind CSS
- Backend: Supabase (PostgreSQL-based)
The implementation process is as follows:
- Create a VueJS template in Replit and set up the frontend environment by installing Tailwind CSS and the @supabase/supabase-js library.
- Create a project in Supabase and build a
messagestable for storing messages via the SQL Editor. - Implement real-time communication functionality by enabling real-time events on the table through Replication settings.
