validate "required"

[keeganstothert]

I see the past issues around validate onSubmit and I would like to give a +1 for that feature. react-select v2 does not support the required prop so ideally we could get around that with a validator like validate: value => !!value

bring on the breaking changes!

I've faced a similar difficulty and wrote about my workaround

I think is might be a great use case for the validate method. I'm not quit sure if there's a need to introduce an additional method to validate the requirement of an input.

Have you considered separating your validators and re-composing? For example, you can have a isRequired function solely for this purpose.

compose = (...fns) => /* compose implementation */;

const isRequired = value => !!value;
const isEmail = value => EMAIL_REGEX.test(value)

<input
  {...text({
    name: 'email',
    validate: compose(isRequired, isEmail),
  })}
/>

That said, I'll keep this in mind for future releases.
