RSS Digest Lab

Fetch an RSS/Atom feed URL, take the top-N items, and generateObject short digests with a regenerate endpoint.

Run this experiment yourself

Demos are not embedded on this site. Deploy a standalone copy on Vercel or run the experiment app locally.

Local development

cd apps/experiments/rss-digest-lab
pnpm install
pnpm dev

Then open http://localhost:3010.

This is an experimental demo. Use it as a starting point for your own projects.

RSS Digest Lab fetches an RSS/Atom feed (capped), parses top-N items locally, and returns one-sentence digests via generateObject. Pass regenerate: true to refresh wording with cache: no-store.

Features

  • Feed parse in logic.ts – RSS item/entry + CDATA heuristics
  • Top-N digests – clamped 1–10
  • Regenerate – same endpoint with fresh prompt angle

Server Reference

POST /api/digest

{ "feedUrl": "https://nextjs.org/feed.xml", "topN": 5, "regenerate": false }

Implementation Details

Pure helpers in logic.ts

Caps, parsers, and clamps live in the experiment folder and are covered by logic.test.ts.

Route Handler

POST /api/digest validates input, applies fetch/parse limits where relevant, then returns JSON from generateObject.

Use Cases

  • Learn composition patterns for this lab’s stack.
  • Prototype before wiring production auth and quotas.
  • Deploy the standalone app as a reference implementation.

Limitations

  • Demo-scale caps on input size and output counts.
  • No auth / rate limits on public deploys.
  • Model quality depends on input clarity.
  • Treat outputs as drafts, not production truth.

Use in your project

Copy the Route Handler and logic.ts helpers from apps/experiments/rss-digest-lab/. Wire your own persistence and auth as needed.
