# PMTiles on Cloudflare Workers

Use [rclone](https://rclone.org/downloads/) to upload your PMTiles archives to an R2 bucket. The Web UI is limited to 300 MB.

# Getting started

Bundled single-file worker with all dependencies:

[protomaps.github.io/PMTiles/worker.js](https://protomaps.github.io/PMTiles/worker.js)

To generate `worker.js` from a checkout:

```sh
git clone https://github.com/protomaps/PMTiles
cd serverless/cloudflare
npm run build
```

Copy `dist/worker.js` into the Cloudflare Workers editor. 

* In Settings > Variables, bind your bucket to the environment variable `BUCKET`.

By default, your worker will serve tiles at path `NAME/0/0/0.pbf` using the archive at the root of your bucket `NAME.pmtiles`.

This behavior can be customized with two optional environment variables:

`PMTILES_PATH` - optional. 
`TILE_PATH`- optional.
`CORS` - optional.
