Progressive Web Apps Development And Analysis With Angular Framework And Service Worker For E

Now, we’ll make the app capable of adding its icon to the desktop or start screen of the device. Now we are ready to use the client in the app component. Of course, you could reuse the so-called “business logic”, meaning, you can take the existing data to reduce the development time. But in fact, you’ll have to start the Progressive Web Apps in 2025 development from scratch if you stick with these PWA frameworks. You would need to write a new code to develop a proper mobile iOS/Android native app from the existing code for PWA. For instance, Vue provides developers with one the easiest learning curves, whereas Angular is a huge framework with a lot of constraints.

Let us navigate to the angular-pwa folder and open VSCode. Put simply, a Progressive Web App is a web app that uses modern web capabilities to deliver an app-like experience to users. These apps are deployed to traditional web servers, are accessible through URLs, and can be indexed by search engines. The last thing is to configure the caching strategies for the app shell and the data. First we need to create ngsw-config.json configuration file under the /src folder.

Adding PWA support also created application icons of various sizes (in the src/assets/icons/ directory). Naturally, you will want to replace them with your own icons. Use any regular image manipulation software to create some cool logos. Finally, a web app manifest was added to the file src/manifest.json. The manifest provides the browser with information that it needs to install the application locally on the user’s device.


They’re installable on mobile devices, meaning you can have a link on your home screen to launch the app right away making it easier to access. In modern browsers, we’ll leverage the amazing APIs we’ll talk about later, but in older browsers, our app should still work perfectly fine, without the amazing modern stuff of course.

The two main requirements of a PWA are a Service Worker and a Web Manifest. While it’s possible to add both of these to an app manually, the Angular team has an @angular/pwa package that can be used to automate this. This file is mainly responsible for the generation of serviceworker.js. Under the hood, ngsw-worker.js uses the service worker API to save cache. The cache can be saved page by route links or manually adding file path. Every Single web request happens, whether it’s an image file in your HTML, CSS file, JS file, AJAX, or anything that happens.

Currently, Angular is at version 14 and Google is the main maintainer of the project. It requires us to create a JSON file containing metadata about the app and link it from the head tag. The manifest file should point to multiple URLs of icons in various sizes. Create a new file in the /src/app folder and name it delivery-client.provider.ts. This provider module needs to export an object defining the factory used to create our client.

Hence it is advisable to take a developer’s input in choosing the framework required for building a progressive web app. As you can see in the image, the application failed to process service workers, Progressive Enhancement, HTTPS, and Web App Manifest. Manifest contains all the JSON configuration that enables web applications to be saved on the user’s home screen. Manifest file should be in the src folder of the project.

Create An Installable Pwa #

It is a javascript file that gets registered with the browser. The advantage of using PWA is that you don’t have to download a huge amount of data to install on your mobile device. Just open the PWA site with your phone or mobile and install it. Our app could also sense when the device transitions from online to offline, and vice versa. We could also use the automatically generated, strongly-typed models of content items from the CMS.

Both are great web development tools for building single-page applications. However, they are different characteristics that either one a better fit in some circumstances. However, the difference lies in how developers build and implement the components on Angular and React. This means that you’ll have all the necessary tools like Angular CLI, RxJS, and Angular Universal within the framework. The manifest file of your app lets you specify your app’s name, short name, icons, theme color, and other details.
