Reactivity adapter for usignal

Adapter

• 🚧 Experimental
• ❌ Automatic Cleanup
• ❌ Scope check

The API of usignal doesn't allow automatic cleanup nor reactive scope checking. Adapters without automatic cleanup are considered as experimental, as a manual cleanup isn't really convenient and a not properly cleanup can lead to memory leaks.

  $ npm install signaldb-plugin-usignal

Usage

import { Collection } from 'signaldb'
import reactivityAdapter from 'signaldb-plugin-usignal'
import { effect } from 'usignal'

const posts = new Collection({
  reactivity: reactivityAdapter,
})

effect(() => {
  const cursor = posts.find({ author: 'John' })
  console.log(cursor.count())
  return () => {
    // usignal doesn't allow to do automatic cleanup, so we have to do it ourself
    cursor.cleanup()
  }
})
