Version 7.40.0-next.1

👍 Improved async defaultValues inference

const fetchData = async () => {
  await sleep(1000)
  return {
    data: 'test'
  }
}

- useForm<Awaited<ReturnTypeof<typeof fetchData>>>({
+ useForm({
  defaultValues: fetchData, // will infer the promise return type
})

👍 Improved useForm resetOptions to keep track of dirty input

- const { formState: { dirtyFields } } = useForm({
+ useForm({ // dirtyFields subscription is no longer required
  values,
  resetOptions: {
    keepDirtyValues; true, // only non dirty input will receive data from the values update
  }
})

🪶 improve useFormContext perf by avoiding reference re-create with omit

Version 7.40.0-next.0

👉 NEW values props

The following syntax will react to values prop update/changes.

• values will be reactive to update/change and reset accordingly
• provide a reset option to keep dirty/touched values potentially

const values = await fetch('API')

useForm({
  values, // will reset the form when values updates
  // resetOptions: {
  //   keepDirtyValues: true
  // }
})

---

👉 NEW async defaultValues props

The following syntax will support async defaultValues, so we will manage the reset form internally and update formState accordingly.

• promise will only be resolved once during useForm() call
• It's possible to supply resetOptions as well

useForm({
  defaultValues: fetch('API')
  // resetOptions: {
  //   keepDirtyValues: true
  // }
})

React use API

useForm({
  defaultValues: use(fetch('API'))
  // resetOptions: {
  //   keepDirtyValues: true
  // }
})

🙋 What's the difference between values and defaultValues

values will react to changes and reflect on the form values, and defaultValues is cached for once and will never re-run the promise or react to defaultValues changes.
