Single file val.town demo of creating a Farcaster frame in a single file
Demo
About
This is a minimal example of a Farcaster frame hosted on val.town. Val Town is a social website to write and deploy TypeScript. This minimal self-contained example demonstrates using the Farcaster frame API, generating images using satori and resvg, and handling POST responses from Farcaster frame. It can serve as a great simple starting point for building frames, and many more things can be added such as a SQLite DB which is offered for free by val.town.
How it's made
This example uses Hono, Satori, ReSVG and business logic to return the appropriate meta tags for the Farcaster frame API. I tested it using the https://warpcast.com/~/developers/frames site. It's all hosted in val.town, and you can look through all the versions of the code that I wrote before getting to the final version on the val.town link.
