Lighthouse Action Plan

Paste Lighthouse JSON - prioritized P0/P1/P2 Next.js fix list grounded in weak audits.

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/lighthouse-action-plan
pnpm install
pnpm dev

Then open http://localhost:3010.

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

Lighthouse Action Plan parses pasted Lighthouse JSON for category scores and weak audits, then returns a prioritized Next.js-oriented fix list via generateObject.

Features

  • Local audit extraction – categories + weak audits before the model call
  • P0/P1/P2 plan – Next.js-specific fix suggestions
  • Sample JSON – performance/SEO-shaped fixture in logic.ts

Server Reference

POST /api/plan

{ "lighthouseJson": "{ ... }" }

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/plan 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/lighthouse-action-plan/. Wire your own persistence and auth as needed.
