@felte/react

Felte is an extensible form library originally built for Svelte but easily integrated with React using this package. Felte, on its most simple form, only requires you to set a ref to your form element to work. No custom Fieldor Form components are needed, making custom styles really easy to do. You can see it in action in this CodeSandbox demo

Features

• Single action to make your form reactive.
• Use HTML5 native elements to create your form. (Only the name attribute is necessary).
• No re-renders at all unless you need to use a specific field's value within your component.
• Provides stores and helper functions to handle more complex use cases.
• No assumptions on your validation strategy. Use any validation library you want or write your own strategy.
• Handles addition and removal of form controls during runtime.
• Official solutions for error reporting using reporter packages.
• Well tested. Currently at 99% code coverage and constantly working on improving test quality.
• Supports validation with yup, zod and superstruct.
• Easily extend its functionality.

Simple ussage example

import React, { useEffect } from 'react';
import { useForm } from '@felte/react';

function Form() {
  const { form } = useForm({
    onSubmit: (values) => console.log(values),
  });

  return (
    <form ref={form}>
      <input name="email" />
      <input name="password" type="password" />
      <button type="submit">Submit</button>
    </form>
  );
}

If your onSubmit would only require you to send your data to a server (either via POST or GET) you don't even need an onSubmit handler by using the action and method attributes:

import React, { useEffect } from 'react';
import { useForm } from '@felte/react';

function Form() {
  const { form } = useForm();

  return (
    <form ref={form} action="/example-signin" method="post">
      <input name="email" />
      <input name="password" type="password" />
      <button type="submit">Submit</button>
    </form>
  );
}
