Farcaster Devs

If Warpcast was open source, what are 1-2 things you would want to learn how we do?

So… I may or may not have stumped @horsefacts.eth and nerd-sniped @cassie into discovering a race condition in Warpcast’s OpenGraph scraper with my *wildly innovative* approach to rendering a SvelteKit website inside of a frame 🙈

Resolution and caching of frame and image URLs.

(Warpcast still can’t seem to consistently decide if skiffle.dev is a frame or an image 😕)

Two things I think would help:

1) If Warpcast knows a URL is meant to be a frame image based on the meta tags, it should send an `Accept` header equivalent to the HTML `<img>` tag in browsers e.g. `image/*`

2) Cache should be indexed by both URL and embed type, not just URL (assuming that’s how it currently works)

SKIFFLE overloads URLs to return either frame HTML or an image based on HTTP content-type negotiation. Hasn’t worked as expected and it's hard to debug without knowing how the resolver works. Specifically:

1) the order it checks URLs for images or frame data

2) what Accept headers are sent when

3) caching behavior
