Pros of Unform

• More mature and established project with a larger community
• Supports both React and React Native out of the box
• Offers a more flexible API for complex form scenarios

Cons of Unform

• Steeper learning curve due to its more complex API
• Less TypeScript-focused, which may result in fewer type safety benefits
• Requires more boilerplate code for basic form setups

Code Comparison

Unform:

import React from 'react';
import { Form } from '@unform/web';
import Input from './components/Input';

function MyForm() {
  function handleSubmit(data) {
    console.log(data);
  }

  return (
    <Form onSubmit={handleSubmit}>
      <Input name="email" />
      <Input name="password" type="password" />
      <button type="submit">Submit</button>
    </Form>
  );
}

React-ts-form:

import { createTsForm } from 'react-ts-form';
import { z } from 'zod';

const schema = z.object({
  email: z.string().email(),
  password: z.string().min(8),
});

const MyForm = createTsForm(schema);

function FormComponent() {
  return (
    <MyForm onSubmit={(values) => console.log(values)}>
      {({ email, password }) => (
        <>
          <email.Field />
          <password.Field type="password" />
          <button type="submit">Submit</button>
        </>
      )}
    </MyForm>
  );
}

Pros of react-hook-form

• More mature and widely adopted, with a larger community and ecosystem
• Offers more advanced features like form validation and error handling out of the box
• Provides better performance optimization for large forms

Cons of react-hook-form

• Steeper learning curve, especially for beginners
• Less TypeScript-focused, which may lead to type-related issues in complex scenarios
• Requires more boilerplate code for basic form setups

Code Comparison

react-hook-form:

import { useForm } from 'react-hook-form';

const { register, handleSubmit } = useForm();
const onSubmit = data => console.log(data);

<form onSubmit={handleSubmit(onSubmit)}>
  <input {...register("firstName")} />
  <input {...register("lastName")} />
  <input type="submit" />
</form>

react-ts-form:

import { createForm } from 'react-ts-form';

const { Form, Field } = createForm<{ firstName: string; lastName: string }>();

<Form onSubmit={data => console.log(data)}>
  <Field name="firstName" />
  <Field name="lastName" />
  <button type="submit">Submit</button>
</Form>

react-ts-form provides a more TypeScript-centric approach with less boilerplate, while react-hook-form offers more flexibility and advanced features at the cost of additional setup.

Pros of Formik

• More mature and widely adopted, with a larger community and ecosystem
• Extensive documentation and examples available
• Flexible and works well with both JavaScript and TypeScript projects

Cons of Formik

• Steeper learning curve for beginners
• Can be overkill for simple form implementations
• Less TypeScript-focused compared to react-ts-form

Code Comparison

react-ts-form:

const { Form } = createForm({
  schema: z.object({
    name: z.string().min(2),
    email: z.string().email(),
  }),
});

Formik:

<Formik
  initialValues={{ name: '', email: '' }}
  validationSchema={Yup.object({
    name: Yup.string().min(2, 'Too Short!').required('Required'),
    email: Yup.string().email('Invalid email').required('Required'),
  })}
  onSubmit={values => {
    // Handle form submission
  }}
>
  {/* Form fields */}
</Formik>

react-ts-form focuses on TypeScript integration and type safety, using Zod for schema validation. Formik uses Yup for validation and provides a more verbose but flexible API. react-ts-form offers a more concise syntax for form creation, while Formik requires more boilerplate but offers greater customization options.

Pros of react-final-form

• More mature and widely adopted in the React community
• Extensive documentation and examples available
• Supports both synchronous and asynchronous validation out of the box

Cons of react-final-form

• Steeper learning curve due to its flexibility and advanced features
• Requires more boilerplate code for basic form setups
• Less TypeScript-friendly compared to react-ts-form

Code Comparison

react-final-form:

import { Form, Field } from 'react-final-form'

<Form
  onSubmit={onSubmit}
  render={({ handleSubmit }) => (
    <form onSubmit={handleSubmit}>
      <Field name="firstName" component="input" placeholder="First Name" />
      <button type="submit">Submit</button>
    </form>
  )}
/>

react-ts-form:

import { createForm } from 'react-ts-form'

const { Form, Field } = createForm<FormSchema>()

<Form onSubmit={onSubmit}>
  <Field name="firstName" component="input" placeholder="First Name" />
  <button type="submit">Submit</button>
</Form>

The code comparison shows that react-ts-form offers a more concise and TypeScript-friendly syntax, while react-final-form provides a more flexible render prop approach. react-ts-form's type inference capabilities make it easier to work with complex form structures in TypeScript projects, whereas react-final-form requires additional type annotations for full TypeScript support.

Pros of TanStack Form

• More comprehensive and feature-rich, offering advanced form management capabilities
• Better performance optimization, especially for large and complex forms
• Extensive documentation and community support

Cons of TanStack Form

• Steeper learning curve due to its complexity and advanced features
• Potentially overkill for simple form implementations
• Requires more setup and configuration compared to react-ts-form

Code Comparison

react-ts-form:

import { createForm } from 'react-ts-form';

const MyForm = createForm({
  firstName: z.string(),
  lastName: z.string(),
});

TanStack Form:

import { useForm } from '@tanstack/react-form';

const form = useForm({
  defaultValues: {
    firstName: '',
    lastName: '',
  },
  onSubmit: async (values) => {
    // Handle form submission
  },
});

Both libraries aim to simplify form management in React applications, but they differ in their approach and feature set. react-ts-form focuses on type-safe form creation with minimal setup, while TanStack Form offers a more robust and flexible solution for complex form scenarios. The choice between the two depends on the specific requirements of your project and the level of control you need over form behavior.
