v1.1.0
✨ Highlights
Self-closing tags in rich text (@nano_kit/intl)
rich (and mapTags) now understand self-closing tags like <br/> and <br /> — handy for line breaks and other void elements in translations. Handlers for such tags are called with empty chunks. Unknown self-closing tags are still stripped as markup.
const [$t] = messages('pages', {
sticker: rich({
br: () => '\n'
})
})
// 'First line<br/>second line' → ['First line', '\n', 'second line']Rich tag handlers receive an unique index (@nano_kit/intl)
Every tag handler now gets an unique index as the second argument — use it as a key for framework nodes:
const [$t] = messages('pages', {
sticker: rich({
title: (chunks, i) => <strong key={i}>{chunks}</strong>,
br: (_, i) => <br key={i} />
})
})No more key warnings and Children.toArray(t.sticker) workarounds in React.
Bonus: mapTags is now reentrant — nested calls from tag handlers no longer clobber the outer call's parsing state.

Nano Kit 1.0 🎉
After a year of alphas and betas, Nano Kit is stable. It is a lightweight, modular state management ecosystem: a signals-based store, data fetching, routing, i18n, and SSR — separate packages, take only what you need. Works with React, Preact, and Svelte, with ready-made integrations for Next.js and SvelteKit.
Why Nano Kit
- Fast. Reactivity is powered by Agera, our fork of alien-signals — one of the fastest reactivity algorithms around. In benchmarks it runs within ~3% of alien-signals itself — ~3.4M subscription updates per second, roughly 1.4× faster than svelte/store and rxjs, 4.5× faster than nanostores, and an order of magnitude ahead of mobx, valtio, and jotai.
- Small. The whole store is ~5 kB min+brotli, a single signal — ~1.6 kB. A real React app with Nano Kit + DI bundles smaller than the same app with TanStack Query or Reatom, and our SSR stack ships 237 kB of frontend JS where TanStack Start ships 375 kB — see bundle size comparisons.
- Dependency injection out of the box. Swap services for tests, SSR, or different platforms without context plumbing — it costs about 1 kB.
- SSR without a meta-framework. Streaming-friendly renderer, hydration, cookies and locale injection — a full SSR app fits in one small hono server.
- TypeScript-first. Strictly typed stores and typed route params, TypeScript 7 ready.
Where to start
- 📚 Documentation — guides for every package
- 🎓 Tutorial — build your first app step by step
- 🌤️ Examples — the same weather and Rick and Morty apps implemented across React, Preact, Svelte, Next.js, SvelteKit, and TanStack stacks, so you can compare like for like
