Getting Started

First, install the dependencies:

Convex Setup

This project uses Convex as a backend. You'll need to set up Convex before running the app:

bun run dev:setup

Follow the prompts to create a new Convex project and connect it to your application.

Copy environment variables from packages/backend/.env.local to apps/*/.env.

Then, run the development server:

bun run dev

Open http://localhost:3001 in your browser to see the web application. Your app will connect to the Convex cloud backend automatically.

Formatting

• Format and lint fix: bun run check
