Service worker error: event already responded to

Service worker error: event already responded to

seems to work fine The problem is that your call to event.respondWith() is inside your top-level promise's .then() clause, meaning that it will be asynchronously executed after the top-level promise resolves. In order to get the behavior you're expecting, event.respondWith() needs to execute synchronously as part of the fetch event handler's execution.
The logic inside of your promise is a bit hard to follow, so I'm not exactly sure what you're trying to accomplish, but in general you can follow this pattern:
code :
self.addEventListerner('fetch', event => {
  // Perform any synchronous checks to see whether you want to respond.
  // E.g., check the value of event.request.url.
  if (event.request.url.includes('something')) {
    const promiseChain = doSomethingAsync()
      .then(() => doSomethingAsyncThatReturnsAURL())
      .then(someUrl => fetch(someUrl));
      // Instead of fetch(), you could have called caches.match(),
      // or anything else that returns a promise for a Response.

    // Synchronously call event.respondWith(), passing in the
    // async promise chain.

service worker install event is called before register event is completed

I wish this helpful for you navigator.serviceWorker.register() is not an event. It's a function that returns a promise, and then promise will resolve with a ServiceWorkerRegistration object that corresponds to the registration.
The actual service worker logic is executed in a different thread/process, and the lifecycle events that the service worker handles, like the install event, happen independently of the web page that registered the service worker. What you're seeing in your console.log() output is expected.

around this issue I have a scenario where i need to send postMessage of latest version files array from client to service worker on the update event of service worker. , I believe you can do something like this:
code :
// sw.js

self.addEventListener('install', function(e) {
    const installPromise = new Promise(function(resolve, reject) {
        // do install stuff, like caching resources, etc.

        self.addEventListener('message', function(e) {
            // 1. do something with the received data
            // 2. remove this event listener

this one helps. Two possibilities that I've faced:
The client ID type you created wasn't for "Chrome App" In the Credentials section of the developers console, click on the name of your client ID, and make sure that the "Applicaiton ID" section is correctly filled out. This should contain the ID shown under chrome://extensions/ as a a 32 character ID just below the description of your extension.

I wish this help you Now, after I solved my error, I will share my solution. It was not a bug in the TF code but one of two things that I tried solved my problem stated above. Because I am working on EC2 instances, the firewall prevents the connection between nodes. So, I made the rule to accept all the traffics to the instances. Second, I was using only IP-address:port-No in the command line. Instead, I wrote it like this, ec2-IP.compute-1.amazonaws.com:2222.
Service worker / Safari / fetch event fires before the message event

Service worker / Safari / fetch event fires before the message event

I think the issue was by ths following , I've tested this example both in Chrome and Safari but I am not relying on the postMessage method to send the form_data parameters. Instead, I am relying on the ServiceWorker's ability to listen for fetch events and grab request parameters inside of the handler.
code :
self.addEventListener(`fetch`, event => {
  const requestClone = event.request.clone()

    (async function() {
      const params = await request.text().catch(err => err)

      if (params instanceof Error) {
        // this is a simple check, but handle error appropriately

      if (event.request.method === `POST`) {
        console.log(`POST request with params: ${params}`)
        // do work here
      return fetch(event.request)
fetch("https://jsonplaceholder.typicode.com/posts", {
  method: "POST",
  body: JSON.stringify({ title: "foo", body: "bar", userId: 1 }),
  headers: { "Content-Type": `application/json` }
  .then(response => response.json())
  .then(json => console.log(`fetch response`, json))
  .catch(error => console.error(`fetch error`, error));

// console logs
//  >> POST request with {"title":"foo","body":"bar","userId":1} (worker.js)
//  >> fetch response {title: "foo", body: "bar", userId: 1, id: 101} (index.js)
