How to get data React UseForm - reactjs

Question

I'm new to React and still am trying to make sense of a few things. I'm using the react-form-dom library and after looking into the documentation I can't figure out what's going on with my project.
I have created a custom input component that takes in a few parameters. The problem is that when I try to log the value of the inputs I get undefined.
Input.jsx
import React, { useState } from 'react';
import './Input.scss';
export default function Input(props, {register, errors}) {
const [inputVal, setInputVal] = useState('');
const nameChange = (e) => {
setInputVal(e.target.value);
props.nameChange(e.target.value);
}
const legend = <span className='legend'>{props?.legend}</span>;
const showLength = <span className='legend'>{props.maxLength - inputVal.length}</span>;
return (
<div className="input-holder">
<input
ref={register}
type={props.type || 'text'}
id={props.id}
placeholder={props.placeholder}
value={inputVal}
onInput={nameChange}
maxLength={props.maxLength || ""}
/>
{ props.legend ? legend : null}
{ props.showLength && props.maxLength ? showLength : null }
</div>
)
}
Form.jsx
import React from 'react';
import { useForm } from "react-hook-form";
import Button from './Button';
import Input from './Input';
export default function UserForm(props) {
const { register, handleSubmit } = useForm();
function submitForm(data) {
console.log(data)
}
return (
<div className="user-form">
<form onSubmit={handleSubmit(submitForm)}>
<Input
placeholder="Name"
nameChange={(name) => props.userName(name)}
showLength="true"
maxLength="35"
legend="Remaining Char: "
id="name"
register={register}
/>
<Input
placeholder="E-mail"
type="email"
id="email"
register={register}
/>
<Button label="Buy" />
</form>
</div>
)
}

It seems that you are using react-hook-form
Checkout the example here
The onChange you are passing to the input tags are no longer needed with react-hook-form beacuse of register functionality of react-hook-form
also validations will be done react-hook-form
import React from 'react';
import { useForm } from "react-hook-form";
export default function UserForm(props) {
const { register, handleSubmit } = useForm();
const submitForm = (data) => {
console.log(data);
}
const onError = (err) => {
console.error(err);
}
return (
<div className="user-form">
<form onSubmit={handleSubmit(submitForm, onError)}>
<input
{...register("name", { //handles onChange, value, name, ref
maxLength: 35 // Your validations
})}
/>
<button>Buy</button>
</form>
</div>
)
}
