react-listener-provider

Create a provider and use HOC (Higher Order Components) to listen for Events in one place.

Usage Example

react-listener-provider exports a ReactListenerProvider component as well as a withListener() wrapper function.

Components wrapped with withListener() will have an added prop listener which exposes add() and remove() methods.

add() and remove() work just like window.addEventListener() and window.removeEventListener(), they take a type <string> argument and a callback <function> argument.

import React, { Component } from 'react';
import ReactListenerProvider, { withListener } from '../../src';

class MouseMove extends Component {
  state = { x: 0, y: 0 };

  componentDidMount() {
    const { add } = this.props.listener;
    add('mousemove', ({ clientX: x, clientY: y }) => this.setState({ x, y }));
  }

  componentWillUnmount() {
    const { remove } = this.props.listener;
    remove('mousemove', ({ clientX: x, clientY: y }) => this.setState({ x, y }));
  }

  render() {
    const { x, y } = this.state;
    return (
      <div>
        <span>x: {x}</span>
        <span> - </span>
        <span>y: {y}</span>
      </div>
    );
  }
}


const WrappedComponent = withListener(MouseMove);


class App extends Component {
  render() {
    return (
      <ReactListenerProvider>
        <WrappedComponent />
      </ReactListenerProvider>
    );
  }
}
