This project was created with Better-T-Stack, a modern TypeScript stack that combines Next.js, Express, and more.

• TypeScript - For type safety and improved developer experience
• Next.js - Full-stack React framework
• TailwindCSS - Utility-first CSS for rapid UI development
• Shared UI package - shadcn/ui primitives live in packages/ui
• Express - Fast, unopinionated web framework
• Bun - Runtime environment
• Mongoose - TypeScript-first ORM
• MongoDB - Database engine
• Authentication - Better-Auth

First, install the dependencies:

bun install

This project uses MongoDB with Mongoose.

1. Make sure you have MongoDB set up.
2. Update your apps/server/.env file with your MongoDB connection URI.

Then, run the development server:

bun run dev

Open http://localhost:3001 in your browser to see the web application. The API is running at http://localhost:3000.

React web apps in this stack share shadcn/ui primitives through packages/ui.

• Change design tokens and global styles in packages/ui/src/styles/globals.css
• Update shared primitives in packages/ui/src/components/*
• Adjust shadcn aliases or style config in packages/ui/components.json and apps/web/components.json

Run this from the project root to add more primitives to the shared UI package:

npx shadcn@latest add accordion dialog popover sheet table -c packages/ui

Import shared components like this:

import { Button } from "@chatapp/ui/components/button";

If you want to add app-specific blocks instead of shared primitives, run the shadcn CLI from apps/web.
