derive

derive util

You can subscribe to some proxies and create a derived proxy.

import { derive } from 'valtio/utils'

// create a base proxy
const state = proxy({
  count: 1,
})

// create a derived proxy
const derived = derive({
  doubled: (get) => get(state).count * 2,
})

// alternatively, attach derived properties to an existing proxy
derive(
  {
    tripled: (get) => get(state).count * 3,
  },
  {
    proxy: state,
  }
)
