Feature request: support synchronous validation about resolvers HOT 9 CLOSED

Hi @Smona 👋🏻

FIY Yup sync validation added in the v2.0.0-beta.5
You can try it by installing yarn add @hookform/[email protected]

from resolvers.

@jorisre hey, awesome! Thanks for taking this on

from resolvers.

@GollyJer v6 will not return defaultValue from watch, unless supplied as default values

watch(undefined, defualtValues)

we are fixing this behaviour for V7, so defaultValue will be returned before render.

resolver: async (data) => schema.validateSync(data)

have you tried to build your own?

from resolvers.

No, not yet. I could, but then I would have to copy-paste the source code for the error parser and other imports of the resolver. Which kind of defeats the purpose of the repo 😅

I'd be happy to submit a PR here if you approve of the idea!

I suppose I'm assuming that useForm would support a synchronous validation resolver. If that's not the case, I can see why this would be harder to implement.

HI @jorisre 👋

Stumbled on this today looking for a synchronous solution.
I have

"@hookform/resolvers": "2.0.0-beta.5",
"react-hook-form": "^6.14.2",

And the following code.

const { control, errors, watch, formState } = useForm<FormInputs>({
    mode: 'onChange',
    reValidateMode: 'onChange',
    defaultValues,
    resolver: yupResolver(
      Yup.object().shape({
        syringeUnits: Yup.number().required().moreThan(0),
        syringeTickMarks: Yup.number().required().moreThan(0),
        powderMilligrams: Yup.number().required().moreThan(0),
        waterMilliliters: Yup.number().required().moreThan(0),
        desiredDoseAmount: Yup.number().required().moreThan(0),
      }),
      undefined,
      { mode: 'sync' }
    ),
  });

  const formValues = watch();
  console.log(formValues);

I'm still seeing formValues print the old and new value when typing in a field.
Am I doing something wrong?

Thanks for the work on this! It's going to be super helpful.
