@future-widget-lab/react-context-provider v0.1.4

@future-widget-lab/react-context-provider

A helper for creating React providers with an associated custom hook. It allows defining shared state logic in a structured way while maintaining type safety.

Features

• Simplifies context creation with an intuitive API.
• Encapsulates state logic inside useGetState for clarity.
• Generates both a Context Provider and a hook for easy consumption.
• Supports TypeScript for strong typing.
• Supports render props for greater flexibility.

Installation

npm install @future-widget-lab/react-context-provider

Usage

Basic Example

import { createContextProvider } from '@future-widget-lab/react-context-provider';

const { ContextProvider: CounterProvider, hook: useCounter } = createContextProvider({
  name: 'counter',
  useGetState: () => {
    const [count, setCount] = React.useState(0);

    const increment = () => setCount((prev) => prev + 1);

    const decrement = () => setCount((prev) => prev - 1);

    const reset = () => setCount(0);

    return { count, increment, decrement, reset };
  }
});

Using the Provider

const App: FC = () => {
  return (
    <CounterProvider>
      <CounterComponent />
    </CounterProvider>
  );
};

Using the Hook

const CounterComponent: FC = () => {
  const { count, increment, decrement, reset } = useCounter();

  return (
    <section style={{ textAlign: 'center' }}>
      <h1>Counter: {count}</h1>
      <button onClick={increment}>+</button>
      <button onClick={decrement}>-</button>
      <button onClick={reset}>Reset</button>
    </section>
  );
};

Using Render Props

const App: FC = () => {
  return (
    <CounterProvider>
      {({ count, increment, decrement, reset }) => {
        return (
          <section style={{ textAlign: 'center' }}>
            <h1>Counter: {count}</h1>
            <button onClick={increment}>+</button>
            <button onClick={decrement}>-</button>
            <button onClick={reset}>Reset</button>
          </section>
        );
      }}
    </CounterProvider>
  );
};
