Jetfuel

Jetfuel is Twitter's new server-driven UI framework which is used for the Creator hub, the new signup/login onboarding flow, the sports and live-events hub, Stories, and more.

emusks talks to the Jetfuel API and decodes the binary into plain JSON for you:

import Emusks from "emusks";

const client = new Emusks();
await client.login("your_auth_token");

// example: global top-posts leaderboard, as real tweets
const { tweets } = await client.jetfuel.topPosts({
  engagement: "Likes",
  period: "Daily",
  country: "USA",
});

for (const t of tweets) console.log(t.text);

WARNING

Jetfuel is freshly reverse-engineered and X changes it without notice. The decoder is best-effort and structural: it recovers framing, strings, the node tree, atom references and reference lists, but it does not resolve the interned style atoms (their dictionary lives in a lazy client chunk). Treat decoded pages as inspectable structure, not a stable schema.
