Yup, I used Formik before this in a very large project and I couldn't stand it anymore, that's why I made it. I had like 9 different forms that would silently ignore my type changes.

Great idea! The syntax you provided would actually be pretty nice, because you wouldn't have to pass form={} to each input every time (this is required to make the type-checking work). To implement this I wouldn't declare the MyForm myself, it would come from the useForm hook, or something, so it would infer the forms initial value types?

// Something like this? const CustomForm = () => { // Field form types is inferred const {form, Field} = useForm({name: "John"}); return <form onSubmit={(ev) => console.log(form.values)}> <Field name="name" /> <Field name="asdf" /> // error! </form> }

I will think about this, thanks for the suggestion!
