It supports most computer devices and is built primarily for Chrome OS machines. We can manually create the Progressive web apps and then install them on the computer as a stand-alone app within the Chrome OS or Chromium browsers.

The Progressive Web Apps, or more popularly known as the Chrome Apps, are small-sized web apps that are majorly built-in JavaScripts and are compatible across all the major browsers.

Although they are lightweight, they still manage to pack in most of the required feature sets. It only takes a couple of seconds for their installation, and the reason for PWA’s popularity is that it has everything one can think of.

These apps offer such a plethora of benefits that many publishers have started integrating PWA counterparts into their websites.

So if you are a publisher or developer who wants to jump into this bandwagon, then this guide is here to help you out.

Here are detailed instructions that shall help you create, test, submit, and subsequently install Progressive Web Apps on your computer.

Create PWA AppCreate a blank folder on your desktop, giving the PWA app the same as the folder name.

After that, you need to code and create a manifest file within that folder. For that, use a text editor such as Notepad++ and create a new JSON or JavaScript Object Notation file.

Input the desired information within the manifest file for your PWA App. It should have the following values:

name — The name that will appear in the Chrome Web Storeversion — The version of the metadataicons — An array specifying the icons that your item usesdescription — A string of 132 characters (maximum) describing your extensionFor example, here’s a JSON file for a bookmark app that you could refer to:

Moving on, once the coding is complete, you need to verify that the codes are formatted correctly. For that, you may use a JSON validator tool such as JSONLint.

If the validation is successful, save this file as manifest.json.

Next up, you will have to design a logo for your app. Make sure that the size is 128p by 128p. Once the logo is created, save it as 128.png inside the same folder where your JSON file is present.

That’s it. You have successfully created the desired miniature version of a PWA App. Let’s now put it to the test.

Test PWA AppLaunch the Chrome browser on your PC and then head to the location below: chrome://extensions/ to open the Chrome extensions page. Enable the Developer Mode toggle from the top right of the page, and click on the Load unpacked button.

Now browse and select the PWA App folder in the explorer window, and hit the Select Folder button.

Once the app is loaded, open a new tab and click the Apps icon within the Chrome browser. Alternatively, you can also visit chrome://apps/ in the address bar.

Select your created PWA and check if it is working correctly or not. If you find any issues, then make the required changes to the manifest.json file and reload the package to Chrome via the Load Unpacked option, as mentioned above.

Now perform the check again and if you have ironed out all the bugs, publish it to the Chrome Web Store!

Publish your App to Chrome Web StoreBefore you proceed ahead with publishing the app, you will first have to verify your target audiences. They are categorized under four segments:

Public: Your app will be available for everyone.Unlisted: Available only to those to whom you share the direct link of your PWA. It wouldn’t appear in the Chrome Web Store.Private: Available only to the testers and debuggers whose names you have listed in the developer dashboard.Group Publishers: Available to the publishers who have paid a one-time developer fee.Once you have made up your mind, let’s get started with the steps to publish your app. First, create a ZIP file of your app package that has the 128.png and the manifest.json file.

Next up, you will have to register yourself as the Chrome Web Store Developer. Head over to this site and proceed with the on-screen instructions to register yourself as a Chrome Web Store developer.

Once your account is created, go to the Chrome Developer Dashboard and sign in with your credentials. Click on Add New Item > Choose File and navigate to your app’s ZIP file; select and hit the Upload button.

Once the file is uploaded, you will have to fill in a few additional details. Fill in the details and click on the Submit for Review button situated at the top right.

After that, enable the checkbox if you want to make the PWA app public using Publish automatically after it has passed review, and click on Submit for Review in the confirmation dialog box.

Your app will undergo review and be published to the Chrome Web Store and if everything’s good (if you had set the target audience to Public).

You shall also receive the status of the review and publish it automatically if everything looks okay.

Install PWA App on ComputerNow that your app is published, let’s install it onto your PC.

Head over to the Chrome Web Store and open the App details page. Click on the Add to Chrome button (Sample below).

Click on the Add Extension button in the confirmation dialog box that appears.

That’s it; the app has been successfully installed onto your PC and is available under chrome://apps/.

In case if you have added your PWA app to the website, then the process will be slightly different.

Head over to your website and then click on the Install icon situated at the extreme right of the Omnibox (for reference, let’s take Google’s Image Compression website Squoosh)

Click Install in the confirmation box, and it shall then install the PWA.
