react-websocket

react-websocket is a simple to use component for ReactJS applications to setup websocket communication.

The component renders an empty element in the DOM. When mounting the component, a websocket connection is opened. The connection will be closed when the component will be unmounted.

Installing

npm install --save react-websocket

Usage

  import React from 'react';
  import Websocket from 'react-websocket';

  class ProductDetail extends React.Component {

    constructor(props) {
      super(props);
      this.state = {
        count: 90
      };
    }

    handleData(data) {
      let result = JSON.parse(data);
      this.setState({count: this.state.count + result.movement});
    }

    render() {
      return (
        <div>
          Count: <strong>{this.state.count}</strong>

          <Websocket url='ws://localhost:8888/live/product/12345/'
              onMessage={this.handleData.bind(this)}/>
        </div>
