React PowerPlug is a versatile library that provides a set of pluggable renderless components and utilities for React applications. It offers various types of state and logic helpers that can significantly simplify your React development process. By leveraging React PowerPlug, developers can create more modular and reusable code, reducing boilerplate and improving overall application structure.

Features

React PowerPlug comes with a rich set of features designed to enhance your React development experience:

  • Renderless Components: Provides logic-only components that manage state and behavior without rendering UI elements.
  • Flexible State Management: Offers various state management solutions for different use cases.
  • Composable Utilities: Allows easy composition of multiple state and logic utilities.
  • TypeScript Support: Includes TypeScript definitions for improved type safety and developer experience.
  • Small Footprint: Lightweight library with minimal impact on bundle size.

Installation

You can easily add React PowerPlug to your project using npm or yarn:

npm install react-powerplug

Or if you prefer yarn:

yarn add react-powerplug

Basic Usage

Let’s dive into some basic examples of how to use React PowerPlug in your React applications.

State Management

One of the core features of React PowerPlug is its ability to manage state easily. Here’s a simple example using the State component:

import React from 'react';
import { State } from 'react-powerplug';

const Counter = () => (
  <State initial={{ count: 0 }}>
    {({ state, setState }) => (
      <div>
        <p>Count: {state.count}</p>
        <button onClick={() => setState(prev => ({ count: prev.count + 1 }))}>
          Increment
        </button>
      </div>
    )}
  </State>
);

In this example, the State component manages the count state, and provides methods to update it. The child function receives the current state and a setState function, allowing for easy state manipulation.

Toggle Component

React PowerPlug provides specialized components for common use cases. The Toggle component is perfect for managing boolean states:

import React from 'react';
import { Toggle } from 'react-powerplug';

const LightSwitch = () => (
  <Toggle initial={false}>
    {({ on, toggle }) => (
      <div>
        <p>The light is {on ? 'on' : 'off'}</p>
        <button onClick={toggle}>Toggle light</button>
      </div>
    )}
  </Toggle>
);

The Toggle component simplifies the management of a boolean state, providing an on value and a toggle function to switch the state.

Advanced Usage

React PowerPlug’s power truly shines in more complex scenarios. Let’s explore some advanced use cases.

Composing Multiple States

React PowerPlug allows easy composition of multiple state management components:

import React from 'react';
import { State, Toggle } from 'react-powerplug';

const AdvancedCounter = () => (
  <State initial={{ count: 0 }}>
    {({ state, setState }) => (
      <Toggle initial={false}>
        {({ on, toggle }) => (
          <div>
            <p>Count: {state.count}</p>
            <p>Counter is {on ? 'active' : 'inactive'}</p>
            <button onClick={() => setState(prev => ({ count: prev.count + 1 }))}>
              Increment
            </button>
            <button onClick={toggle}>
              {on ? 'Deactivate' : 'Activate'} counter
            </button>
          </div>
        )}
      </Toggle>
    )}
  </State>
);

This example combines the State and Toggle components to create a more complex counter with an active/inactive state.

Using the Value Component

The Value component is a versatile tool for managing any type of value:

import React from 'react';
import { Value } from 'react-powerplug';

const ColorPicker = () => (
  <Value initial="#000000">
    {({ value, set }) => (
      <div>
        <input
          type="color"
          value={value}
          onChange={e => set(e.target.value)}
        />
        <p>Selected color: {value}</p>
      </div>
    )}
  </Value>
);

The Value component provides a simple way to manage and update a single value, in this case, a color code.

List Management

For managing lists of items, React PowerPlug offers the List component:

import React from 'react';
import { List } from 'react-powerplug';

const TodoList = () => (
  <List initial={['Buy groceries', 'Clean the house']}>
    {({ list, push, remove }) => (
      <div>
        <ul>
          {list.map((item, index) => (
            <li key={index}>
              {item}
              <button onClick={() => remove(index)}>Remove</button>
            </li>
          ))}
        </ul>
        <input
          type="text"
          placeholder="New todo"
          onKeyPress={e => {
            if (e.key === 'Enter') {
              push(e.target.value);
              e.target.value = '';
            }
          }}
        />
      </div>
    )}
  </List>
);

The List component provides methods like push and remove to easily manipulate the list of items.
