The domStreams component property enables you to access Events from your Vue.js templates as Streams insides your subscriptions function. You can then map the Events to other values and stream them back into your Vue.js templates.

<template>
  <section class="section">
    <button 
 
class="button" v-stream:click="click$">Click</button>
    <h1 class="title">{{random$}}</h1>
  </section>
</template>

<script>
import { Observable } from "rxjs"

export default {
  domStreams: ["click$"],
  subscriptions() {
    const random$ = this.click$.map(() 
 
=>
      Math.random()
    )

    return {
      random$
    }
  }
}
</script>
