Supabase with Cloudflare Workers

Cloudflare Workers does not support XMLHttpRequest object and only support native fetch. This means this supabase-js client does not work on Cloudflare Workers. Supabase JS Client internally uses cross-fetch package to polyfill fetch which relies on XMLHttpRequest.

To resolve this, we can use patch-package to patch cross-fetch package as minimal as possible.

This repo contains minimal Cloudflare Workers project with the patch automatically applied.
