## ReplayWeb.page CORS Helper
This is an optional, tiny utility script that runs as a [Cloudflare Worker](https://workers.cloudflare.com/), and is designed to improve experience for
https://replayweb.page/ by performing checks that are not possible directly due to CORS restrictions.
It's main function is to determine if a Google Drive file is publicly available, and if so, resolve the public
URL and pass back to [ReplayWeb.page](https://replayweb.page/) so that the file can be loaded directly.
It does not actually proxy any content.
Running this script is not required to use [ReplayWeb.page](https://replayweb.page/), without it,
ReplayWeb.page will assume all Google Drive URLs are not public.
### Google Drive Access CORS Check
API: -> `/g/<google drive fileId>`
Returns:
- `{auth: true}` - if file is not public
- `{url, name, size}` - if file is public and can be downloaded directly.
### CORS size check
Another API is to simply check the `Content-Length`, which occasionally is not available due to CORS (if `Access-Control-Expose-Headers` is not set)
API: -> `<script endpoint>/c/<url>`
Returns:
- `{size, cors}` - size of file and if CORS access from origin domain is available
- `{error}` - if an error occurs
### Usage
Copy the `wrangler.toml.sample` -> `wrangler.toml` and fill in credentials.
Publish with `wrangler publish`.
See [Cloudflare Worker API Docs](https://developers.cloudflare.com/workers/tooling/wrangler) for more details.
