dprint-plugins-proxy

What it do?

This is a stupidly simple proxy for the dprint.dev website, which adds an Access-Control-Allow-Origin header (and some conditional cache controls) to allow CORS requests to the WebAssembly plugins hosted on the site.

It forwards all requests from https://dprint.deno.dev/* -> https://plugins.dprint.dev/*, and if it encounters a 404 then it attempts to forward to https://dprint.dev/* instead.

When it detects HTML content, it rewrites any dprint.dev URLs in the content to use the Deno Deploy origin of the proxy server instead. Requests that appear to be for WASM files are cached as immutable assets with a max age of 1 year.

But why?

I was getting CORS errors trying to fetch dprint plugins. Half a coffee later and here we are.
