I took the example from the documentation :
import React from "react"; import { useForm } from "react-hook-form"; export default function App() { const { register, handleSubmit, watch, formState: { errors } } = useForm(); const onSubmit = data => console.log(data); console.log(watch("example")); return ( <form onSubmit={handleSubmit(onSubmit)}> <input defaultValue="test" {...register("example")} /> <input type="submit" /> </form> ); }
But on every change or on submit, I got undefined
for each field
I tried to install the library again but nothing change and I got undefined everywhere…seems to be a problem with the register function. Does anybody got the same issue ?

With v7 the usage of register
changed as noted in the comments. If you still need to use v6, you have to write it like this:
function App() { const { register, handleSubmit, watch, formState: { errors } } = useForm(); const onSubmit = data => console.log(data); console.log(watch("example")); return ( <form onSubmit={handleSubmit(onSubmit)}> <input defaultValue="test" name="example" ref={register} /> <input type="submit" /> </form> ); }
