Yet another implementation for Jotai atoms without side effects

## Introduction

This library used to be a former library to [jotai](https://github.com/pmndrs/jotai).
It's now rewritten to follow jotai API and depends on
[use-context-selector](https://github.com/dai-shi/use-context-selector).
The biggest difference is that side effects in `write` is not allowed.

## Install

```bash
npm install use-atom jotai
```

## Usage

```javascript
import React from 'react';
import ReactDOM from 'react-dom';

import { Provider, atom, useAtom } from 'use-atom';

const countAtom = atom(0);
const textAtom = atom('hello');

const App = () => (
  <Provider>
    <h1>Counter</h1>
    <Counter />
    <Counter />
    <h1>TextBox</h1>
    <TextBox />
    <TextBox />
  </Provider>
);
```

## Examples

The [examples](examples) folder contains working examples.
You can run one of them with

```bash
PORT=8080 npm run examples:01_minimal
```

and open <http://localhost:8080> in your web browser.

You can also try them in codesandbox.io:
