React Use Polling

react-use-polling is a custom React hook that simplifies periodic polling with error handling in your React applications. It allows you to easily fetch and update data at regular intervals while handling errors gracefully.

Installation

You can install the react-use-polling package from npm using the following command:

npm install @eballoi/react-use-polling

Usage

To use the usePolling hook in your React components, follow these steps:

1. Import the hook:

import usePolling from '@eballoi/react-use-polling';

2. Create a polling callback function that fetches your data. For example:

const pollingCallback = async () => {
  // Your data fetching logic here
  const response = await fetchDataFromApi();
  return response.data;
};

3. Set up polling options:

const pollingOptions = {
  interval: 5000, // Polling interval in milliseconds (e.g., every 5 seconds)
  onError: (error) => {
    // Handle errors here (optional)
    console.error('Polling error:', error);
  },
};

4. Use the usePolling hook within your component:

const YourComponent = () => {
  const { data, loading, error } = usePolling(pollingCallback, pollingOptions);

  return (
    <div>
      {loading && <p>Loading...</p>}
      {error && <p>Error: {error.message}</p>}
      {data && <p>Data: {data}</p>}
    </div>
  );
};

API

usePolling(callback: () => Promise<any>, options: PollingOptions): PollingResult

• callback: A function that returns a promise, which should fetch the data for polling.

• options (optional): An object containing polling configuration options:

  • interval (number, required): The polling interval in milliseconds.
  • onError (function, optional): A callback function to handle errors when they occur during polling.

PollingResult

The usePolling hook returns an object with the following properties:

• data: The latest data fetched during polling.
• loading: A boolean indicating whether polling is in progress.
• error: An error object if an error occurred during polling; otherwise, it's null.
