Show HN: Get your coding agent off ~2019 JavaScript, onto modern web primitives

What HN thinks

Google offers to modernize your agent; half the thread checks its wallet for Chrome-only APIs.

Worried about Chrome-only bias
Critics note many recommended features are Chrome-only and fear agents will entrench the Chrome monoculture; maintainers reply that support tables, fallbacks, and Mozilla/Edge participation keep it cross-browser.
Default to widely available only
Several want the guidance filtered mechanically to Baseline widely-available features for their target browsers, rather than spending tokens letting the agent reason about each feature.
Useful against legacy slop
Supporters welcome replacing verbose old patterns with one-line modern features and see maintainability as the next frontier for AI-written code.

Consensus: No firm consensus; most agree the documentation of compatibility and fallbacks is solid but disagree on whether bleeding-edge features should be suggested by default.

Recommended in the comments

Baseline ↗ (other): Cited as the standard for deciding which features are safe to use everywhere.
Alpine.js (library): Pairs well with SSR-first sites, keeping small bits of JS next to the HTML.
Tailwind CSS (library): Keeps styling close to the markup it styles.
kotlinx.html (library): Lets templates be plain typed code instead of string interpolation.
HtmlFlow (library): Same code-as-templates approach as kotlinx.html.
