What is a fetch event in Magento PWA?

After a service worker is installed and the user navigates to a different page or refreshes, the service worker will begin to receive.

 A event fires every time any resource controlled by a service worker is fetched, which includes the documents inside the specified scope, and any resources referenced in those documents (for example if index.html makes a cross origin request to embed an image, that still goes through its service worker.)

import React, { useEffect, useState } from ‘react’;

import { fetchEventCode } from ‘path-to-your-api’; // Replace with the actual path

const YourComponent = () => {

 const [eventCode, setEventCode] = useState(null);

 useEffect(() => {

  // Function to fetch event code

  const fetchData = async () => {

   try {

    const response = await fetchEventCode(); // Replace with the actual fetch function

    const data = await response.json();

    setEventCode(data.eventCode);

   } catch (error) {

    console.error(‘Error fetching event code:’, error);

   }

  };

  // Call the function to fetch data

  fetchData();

 }, []); // The empty dependency array ensures that this effect runs once when the component mounts

 return (

  <div>

   <h1>Event Code: {eventCode}</h1>

   {/* Render the rest of your component */}

  </div>

 );

};

export default YourComponent;

Make sure to replace ‘path-to-your-api’ with the actual path to the API endpoint that fetches the event code. Also, replace fetchEventCode with the actual function responsible for fetching the event code.
