ReactNetworkStatus

• This is a React Js library that provides network status (online/offline) with polling.

Installation

npm i react-network-status or yarn add react-network-status

Usage

useNetworkStatus Hook for functional Components in React

Hook that updates component with the network status offline/online state.

This gives user a flexibility to programmatically render UI components.

import { useNetworkStatus } from "react-network-status";

const App = () => {
  const [networkStatus, setNetworkStatus] = useState(true);
  const config = {
    timeout: 5000,
    interval: 1000,
  };

  useNetworkStatus((networkStatusUpdate) => {
    setNetworkStatus(networkStatusUpdate);
  }, config);

  return <div>You are: {networkStatus ? "online" : "offline"}</div>;
};

Components

NetworkDetector - Component that can be used in State based Components.

It has no UI but just accepts config and onChange event.

import { NetworkDetector } from "react-network-status";

class App extends Component {
  state = {
    networkStatus: true,
  };

  config = {
    timeout: 5000,
    interval: 1000,
  };

  onNetworkStatusChange = (networkStatus: boolean) => {
    this.setState({ networkStatus });
  };

  render() {
    const { networkStatus } = this.state;

    return (
      <div>
        You are: {networkStatus ? "online" : "offline"}
        <NetworkDetector
          config={this.config}
          onChange={this.onNetworkStatusChange}
        />
      </div>
    );
  }
}

const config = {
  url: // YOUR_POLLING URL,
  interval: // YOUR POLLING INTERVAL,

config.url	String	URL to pool for connection status	"https://ipv4.icanhazip.com"
config.interval	Number	How often (in ms) to poll	5000
