I made the first ever stateless no-backend Farcaster miniapp! It's a spoiler hider which encodes the state in the URL (which is allowed as of... today).

Farcaster Devs

We’ve just relaxed the `launch_frame` action schema:

`button.action.url` is now optional. If you omit it, we fall back to the full URL of the page that loaded the frame (including any query‑string params).

Let us know if anything feels off, or open an issue. Happy shipping! 🙂

This works thanks to this change: https://warpcast.com/pirosb3/0x1b422b49

Oops the fc:frame metadata wasn't quite right when the original cast was published, here's what it should actually look like when embedded... this URL won't show:

I ran into a bug in the Warpcast posting API where I get 500 errors if an embed URL is long, stay tuned! 🫠

Okay figured out the problem, embed URLs are limited to 256 bytes which is quite small. @v @dwr.eth Can we lift this limit?

I get the point of putting an upper bound on protocol messages, but perhaps it should be a total message size limit instead? (So that I can trade off smaller body text for allowing larger embed URLs?)

pls don't make me build an onchain link shortener 🥺🥺🥺

Hehe mostly congrats to @deodad for the idea 😂 he was the one who originally understood the need for this

That's awesome! congrats on being the first 🏆
