A Farcaster Frames tutorial with a demo and architecture overview

This tutorial walks through building a Farcaster Frame, the interactive embed format that extends Open Graph metadata, using a trivia game called "MVP or Not MVP" as the demo. The author describes four components: a Frame front-end that renders URLs with Frame meta tags, a Frame Server that handles button taps and advances the game, persistent storage for game state, and a Farcaster Hub for validating FIDs and message data, which the demo uses Neynar for. The core loop is render, interact, call the Frame Server, and repeat, with the game split into /start, /next (levels 1 through 5) and /over stages. The stack includes Next.js 14, React, Vercel, Satori and Sharp for image generation, and TypeScript.
