# Sandbox 📦🪄

Sandbox is an open-source cloud-based code editing environment with custom AI code autocompletion and real-time collaboration.

## Running Locally

### Frontend

Install dependencies

```bash
cd frontend
npm install
```

Add the required environment variables in `.env` (example file provided in `.env.example`)

Then, run in development mode

```bash
npm run dev
```

### Backend

The backend consists of a primary Express and Socket.io server, and 3 Cloudflare Workers microservices for the D1 database, R2 storage, and Workers AI. The D1 database also contains a [service binding](https://developers.cloudflare.com/workers/runtime-apis/bindings/service-bindings/) to the R2 storage worker.

#### Socket.io server

Install dependencies

```bash
cd backend/server
npm install
```

Add the required environment variables in `.env` (example file provided in `.env.example`)

Project files will be stored in the `projects/<project-id>` directory. The middleware contains basic authorization logic for connecting to the server.

Run in development mode

```bash
npm run dev
```

### Cloudflare Workers (Database, Storage, AI)

Install dependencies

```bash
cd backend/<database | storage | ai> # do these individually
npm install
```

For each, add the required environment variables in `.env` (example file provided in `.env.example`). For the AI worker, you can define any value you want for the `CF_AI_KEY` -- set this in other `.env` files to authorize access.

Run in development mode

```bash
npm run dev
```
