# Bolt

Bolt is an AI assistant developed by StackBlitz. This package contains the UI interface for Bolt as well as the server components, built using [Remix Run](https://remix.run/).

## Prerequisites

Before you begin, ensure you have the following installed:

- Node.js (v20.15.1)
- pnpm (v9.4.0)

## Setup

1. Clone the repository (if you haven't already):

```bash
git clone https://github.com/stackblitz/bolt.git
cd bolt
```

2. Install dependencies:

```bash
pnpm install
```

3. Create a `.env.local` file in the root of the bolt package directory and add your Anthropic API key:

```
ANTHROPIC_API_KEY=XXX
```

Optionally, you an set the debug level:

```
VITE_LOG_LEVEL=debug
```

If you want to run authentication against a local StackBlitz instance, add:

```
VITE_CLIENT_ORIGIN=https://local.stackblitz.com:3000
```

**Important**: Never commit your `.env.local` file to version control. It's already included in .gitignore.

## Available Scripts

- `pnpm run dev`: Starts the development server.
- `pnpm run build`: Builds the project.
- `pnpm run start`: Runs the built application locally using Wrangler Pages. This script uses `bindings.sh` to set up necessary bindings so you don't have to duplicate environment variables.
- `pnpm run preview`: Builds the project and then starts it locally, useful for testing the production build. Note, HTTP streaming currently doesn't work as expected with `wrangler pages dev`.
- `pnpm test:` Runs the test suite using Vitest.
- `pnpm run typecheck`: Runs TypeScript type checking.
- `pnpm run typegen`: Generates TypeScript types using Wrangler.
- `pnpm run deploy`: Builds the project and deploys it to Cloudflare Pages.

## Development

To start the development server:

```bash
pnpm run dev
```

This will start the Remix Vite development server.

## Testing

Run the test suite with:

```bash
pnpm test
```

## Deployment

To deploy the application to Cloudflare Pages:

```bash
pnpm run deploy
```

Make sure you have the necessary permissions and Wrangler is correctly configured for your Cloudflare account.
