  v0.1.0 Stable

  yt-dlp.wasm v0.1.0 — initial release

  Pure-Rust WebAssembly YouTube extractor. Compiled with wasm-pack
  --target web; runs entirely client-side in a modern browser.

  Highlights

  • YouTube extractor calls InnerTube directly with the ANDROID client
    context (no HTML scraping, no SABR). Returns plain per-format URLs
    all the way up to 4K (2160p) with full videoDetails, captions, and
    thumbnails — no signature cipher and no n-param transform needed.
  • Unified Format / Subtitle / VideoInfo schema matching yt-dlp's
    info_dict subset.
  • CORS proxy plumbing via window.fetch_with_proxy (GET) and
    window.fetch_post_with_proxy (POST). Proxy URL is runtime-
    configurable from the host page.
  • Stub extractors in place for X/Twitter, TikTok, and Instagram.

  Bundle (yt_dlp_wasm-v0.1.0.zip)

  • yt_dlp_wasm.js — wasm-bindgen JS glue (ES module)
  • yt_dlp_wasm_bg.wasm — the compiled module
  • yt_dlp_wasm.d.ts — TypeScript definitions
  • yt_dlp_wasm_bg.wasm.d.ts — wasm-bindgen type stubs
  • package.json — npm-style metadata

  Usage
  import init, { extract, supported_sites } from './yt_dlp_wasm.js';
  await init();
  const info = await extract('https://www.youtube.com/watch?v=...', /* useProxy */ true);

  Host page must define window.fetch_with_proxy and
  window.fetch_post_with_proxy — see index.html in the source tree for
  a reference implementation.

  Note on YouTube version drift
  YouTube enforces a minimum ANDROID clientVersion. v0.1.0 ships with
  20.10.38. When YouTube tightens this again, bump
  ANDROID_CLIENT_VERSION in src/extractor/youtube.rs to whatever
  yt-dlp's _DEFAULT_CLIENTS currently uses.
