Show HN: LARC – Web Components with 500 tests and PAN messaging

First Comment (Post within 2 minutes)

Hi HN! Creator here.

LARC solves the Web Component coordination problem with PAN (Page Area Network) -
a lightweight message bus for the browser.

Technical highlights:
• 500 tests passing (335 core + 165 UI) across Chromium, Firefox, WebKit
• 5KB core (gzipped), zero dependencies
• Works with React, Vue, Svelte—mix and match
• Zero-build dev, optional build prod
• TypeScript support
• Published on npm (@larcjs/core@3.0.1)

Live playground: https://larcjs.com/playground/

The killer demo: React + Vue + LARC components on the same page,
coordinating via PAN messages. No framework knows about the others.

Philosophy: Complement frameworks, don't replace them. Use LARC for
cards, modals, tables and keep React/Vue for complex app logic.

Happy to answer questions!

Monitoring Strategy

First 2 hours: Check HN every 5 minutes
Hours 2-6: Check every 15-30 minutes
Evening: Final check before EOD
Day 2-7: Daily monitoring and responses

🎯 Key Talking Points (Be Ready)

What is LARC?

Web Component framework with zero-build development and PAN messaging for component coordination.

Why another framework?

Not replacing React/Vue—complementing them. Reduce bundle size 60%+ by using LARC for shared UI components (cards, modals, tables) and keep frameworks for complex app logic.

What's PAN?

Publish-Apply-Notify: A pub/sub message bus like MQTT for the browser. Components coordinate without coupling. Theme toggle publishes "theme.changed", all components subscribe and react automatically.

Production ready?

Yes: 500 tests (100% passing), 0 vulnerabilities, 4 CodeQL security issues fixed, v2.0.0 on npm. Young ecosystem but stable core. Perfect for early adopters.

Bundle size comparison?

- LARC Core: 5KB (gzipped)

- React: 140KB (React + ReactDOM)

- Vue: 90KB

- Per-component: 2-5KB each

Browser support?

Chrome 90+, Firefox 88+, Safari 14+, Edge 90+. Modern browsers only (Web Components API required).

TypeScript support?

Full support with @larcjs/core-types and @larcjs/ui-types packages.

Learning curve?

If you know HTML + vanilla JavaScript, you're ready. No JSX, no new syntax, no build tools required in dev.

🎉 Unique Selling Points

Emphasize these:

✅ 500 tests - Comprehensive test coverage (just achieved!)

✅ Zero-build dev - Write .mjs, refresh browser

✅ PAN messaging - Solves Web Component coordination

✅ Framework complement - Not a replacement

✅ 5KB core - 96% smaller than React

✅ True interop - React + Vue + LARC on same page

✅ No vendor lock-in - Standard Web Components + messaging

✅ Complete ecosystem - CLI, registry, VS Code extension

✅ Security-audited - 0 vulnerabilities, all CodeQL alerts fixed

✅ CI/CD automated - Every commit tested on 3 browsers

🚨 Potential Objections (Prep Answers)

"Another JavaScript framework? Really?"

Fair pushback! But LARC isn't replacing React/Vue—it complements them. Use LARC for shared UI (cards, modals, tables) and keep your framework for app logic. You get 60%+ bundle reduction without rewriting your app.

"Web Components are dead"

Web Components are a W3C standard, implemented in all modern browsers, and used by major companies (GitHub, Microsoft, ING Bank). They're not dead—just undersold because coordination is hard. PAN fixes that.

"What about X feature?"

Great question! We focused on core messaging and UI components first. [Feature] is on the roadmap. Would love your input on GitHub Discussions!

"Bundle size doesn't matter with HTTP/2"

True for downloads, but parse/eval time matters for mobile devices. A 5KB framework evaluates 28x faster than a 140KB one. Mobile users feel the difference.

"Is anyone using this in production?"

Yes, but it's a young project (Nov 2024 launch). We'd love more production feedback! The core is stable (500 tests) but the ecosystem is growing. Perfect for early adopters willing to shape the roadmap.
