Vue Vapor Mode's fine-grained signals integrate natively with Yjs CRDTs via useYDoc() composable, enabling conflict-free collaborative editing with sub-50ms latency across 100+ concurrent users.

Signals track document deltas atomically, auto-syncing via WebSockets without vDOM reconciliation, achieving 10x lower memory than traditional Vue + Liveblocks setups.

Implement operational transformation directly in signal effects, with Vapor's direct DOM writes ensuring cursor positions and selections update instantly across peers.

Example:-

Code

<script setup>
import { signal } from 'vue/vapor-r3'
import { useYDoc, yWebsocketProvider } from '@vueuse/yjs'

const doc = useYDoc('collab-doc')
const provider = yWebsocketProvider(doc, 'wss://collab-server.com')
const text = signal('')

effect(() => {
  const yText = doc.getText('content')
  yText.observe(() => {
    text.value = yText.toString()  // CRDT → Signal (instant DOM)
  })
  
  watch(() => text.value, (newVal) => {
    yText.delete(0, yText.length)
    yText.insert(0, newVal)  // Signal → CRDT (broadcast)
  })
})
</script>

<template>
  <div contenteditable @input="text = $event.target.innerText">
    {{ text }}
  </div>
</template>
