> Auto save controlled form values as they are updated.

react-autosave is a lightweight solution for auto saving controlled form values.
It handles many edge cases and guarantees a good user experience.

## Examples

```tsx
import React from 'react';
import axios from 'axios';

import { Autosave, useAutosave } from 'react-autosave';

const updateBlog = (data) => axios.post('myapi/blog/123', { text: data });

// Via hook
const EditBlogFormWithHook = () => {
  const [blogText, setBlogText] = React.useState('hello world');
  useAutosave({ data: blogText, onSave: updateBlog });
  return (
    <div>
      <input
        type="text"
        value={blogText}
        onChange={(e) => setBlogText(e.target.value)}
      />
    </div>
  );
};

// Via component
const EditBlogForm = () => {
  const [blogText, setBlogText] = React.useState('hello world');
  return (
    <div>
      <input
        type="text"
        value={blogText}
        onChange={(e) => setBlogText(e.target.value)}
