This repository contains a full-stack application that integrates Discord OAuth2 for authentication with Firebase to manage authenticated sessions. The system is divided into two main parts:

• Backend (discord-auth-backend): Implemented with NestJS, it handles Discord OAuth2 authentication, user data retrieval, and Firebase custom token generation.
• Frontend (discord-auth-frontend): Built with React, it utilizes Firebase to authenticate users based on the tokens generated by the backend and manage user sessions.

1. Clone the repository

   git clone https://github.com/nawodyaishan/discord-firebase-auth.git
   cd discord-firebase-auth

2. Set up the backend

   cd discord-auth-backend
   yarn install
   # Configure environment variables in .env file
   yarn start
