Clone this repo locally with the following command:

bunx degit midday-ai/v1 v1

1. Install dependencies using bun:

bun i

2. Copy .env.example to .env and update the variables.

# Copy .env.example to .env for each app
cp apps/api/.env.example apps/api/.env
cp apps/app/.env.example apps/app/.env
cp apps/web/.env.example apps/web/.env

4. Start the development server from either bun or turbo:

bun dev // starts everything in development mode (web, app, api, email)
bun dev:web // starts the web app in development mode
bun dev:app // starts the app in development mode
bun dev:api // starts the api in development mode
bun dev:email // starts the email app in development mode

// Database
bun db:push // push schema changes to database
bun db:studio // open Drizzle Studio to manage your database
bun db:seed // run seed data

This boilerplate is inspired by our work on Midday, and it's designed to serve as a reference for real-world apps. Feel free to dive into the code and see how we've tackled various features. Whether you're looking to understand authentication flows, database interactions, or UI components, you'll find practical, battle-tested implementations throughout the codebase. It's not just a starting point; it's a learning resource that can help you build your own applications.

With this, you have a great starting point for your own project.
