Workers Database Management System for Durable Objects

This project aims to provide a standard interface for "traditional" frameworks that are currently not supported by
cloudflare workers to be able to use Durable Objects with SQLite as the backend database!

The main differences from Cloudflare D1 are:
- Websocket support (this really makes a difference when executing dozens of queries sequentially)
- Experimental transactions support

## Features
- On demand SQLite databases (like neon.tech)
- https endpoints to manage and query databases
- Websocket endpoint to query databases
- **Transactions support** in websocket mode!

## Supported frameworks
- Django using [django-cf](https://github.com/G4brym/django-cf)

## Get started

```bash
npm install --save workers-dbms
npm install --save wrangler
```

Create a `index.ts` file with this:
```ts
import { generateApp } from "workers-dbms";
export { DBMSDO } from "workers-dbms";

export default generateApp()
```

Create a `wrangler.toml` file with this:
```toml
#:schema node_modules/wrangler/config-schema.json
name = "workers-dbms"
main = "index.ts"
compatibility_date = "2024-09-28"
# workers_dev = false  # uncomment this for enhanced security !

[[durable_objects.bindings]]
name = "DBSM_DO"
class_name = "DBMSDO"

[[migrations]]
tag = "v1"
new_sqlite_classes = ["DBMSDO"]
```

Deploy your dbms with wrangler:
```bash
wrangler deploy
```

You can now access your dbms on the worker deployed url

There is also a swagger interface with all the endpoints documented at `/api` path.

## FAQ

### Handshake status 426 Upgrade Required

When using a custom domain for your worker, make sure to enable WebSockets on the domain Network configuration,
otherwise you will not be able to use the websocket endpoint!

### Anyone can access my databases

1. For secure databases, you should uncomment the `workers_dev = false` line in your `wrangler.toml`
2. Create a custom domain for your worker [docs here](https://developers.cloudflare.com/workers/configuration/routing/custom-domains/#add-a-custom-domain)
3. Setup zero trust for this worker [docs here](https://developers.cloudflare.com/cloudflare-one/applications/configure-apps/self-hosted-apps/)
