CORS Helpers

[sergiodxa]

Setting CORS headers to allow using a Remix app as an API for another website is tedious and error prone.

Remix Utils could provide a simple helper to setup that.

cors(response)

Should set all the required headers on the Response object. It can work in two ways:

1. Change the Response object directly so you can keep using it later.
2. Return the Response so you can do return cors(json<LoaderData>(data)) to compose them.

Additionally, cors could receive a second object with options to configure it easily.

This helper, could also be used inside entry.server's handleDataRequest function to apply CORS to every data request or manually to each loader and action you want to enable CORS for.
