What is svelte-realtime?

svelte-realtime brings native WebSocket RPC and reactive subscriptions to SvelteKit apps via uWebSockets.js, a high-perf native websocket api. Drop server functions into a live directory, import them client-side with $live/module, and get instant async RPC calls plus Svelte stores that load initial data and auto-merge live updates—no manual pub/sub wiring or protocol design. It beats native websocket vs socket io with zero-boilerplate streams for chats, presence, or feeds, akin to supabase realtime svelte but fully native.

Why is it gaining traction?

Its Vite plugin auto-generates typed client stubs, supports merge strategies (CRUD lists, presence, cursors), optimistic updates, batching, offline queues, and SSR hydration—features devs notice in smoother UIs without extra libs. Native websocket nodejs perf shines in benchmarks, outpacing Socket.io while handling delta sync, replay, and schema evolution. Early github native alpha buzz comes from SvelteKit-first simplicity over fragmented alternatives.

Who should use this?

SvelteKit fullstack devs building realtime chats, collaborative editors, or live dashboards who hate boilerplate. Teams ditching Supabase Realtime or Firebase Realtime Database for self-hosted native websocket client control, especially with dynamic per-user/room streams.

Verdict

Promising github native alpha for SvelteKit realtime (40 stars, 1.0% credibility score)—thorough docs, tests, DevTools, but github native automerge not enabled in repo settings signals early days. Prototype with it now if perf matters; watch for production hardening.
