AI-Generated Review

What is svelte-adapter-uws?

This JavaScript SvelteKit adapter swaps out slow defaults like adapter-node or adapter-vercel for uWebSockets.js, the fastest Node.js HTTP/WebSocket server. It delivers native HTTPS/WSS, in-memory static caching with brotli/gzip, and zero-config pub/sub WebSockets via a reactive Svelte client store that auto-connects and handles CRUD updates. Run `npm run build && node build` for production, with env vars like `SSL_CERT` enabling TLS without proxies.

Why is it gaining traction?

Unlike adapter-static, adapter-aws, or adapter-bun, it crushes benchmarks—6x faster static files, 2x SSR over adapter-node—while bundling WebSocket pub/sub that rivals Socket.io without the bloat. Dev mode mirrors prod via a Vite plugin, supporting `event.platform.publish` in hooks and actions for real-time pushes. Built-in health checks at `/healthz` and clustering via `CLUSTER_WORKERS=auto` scale effortlessly.

Who should use this?

SvelteKit backend devs building live dashboards, chat apps, or collaborative tools who hate Socket.io setup. Full-stack teams self-hosting instead of Vercel/Azure, or forking GitHub repos like sveltekit github examples needing real-time without superforms boilerplate. Pairs well with paraglide-sveltekit for i18n-heavy sites.

Verdict

Grab it for perf-critical SvelteKit apps—docs, examples, and TypeScript support are pro-level despite 11 stars and 1.0% credibility signaling early days. Test with Docker on node:22-trixie-slim; maturity lags big adapters but benchmarks don't lie.
