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 recently released PWA Builder 2.0 also extends its official support to the Mac desktop platform driven by WebKit. The framework aims to create cross-platform PWAs, including availability in places that shouldn’t be possible such as Microsoft Store and Mac. Yes, macOS, as the recently released 2.0 version of PWA Builder has extended its official support to WebKit-powered browsers. Angular progressive web apps can be made very easily if you already have an existing Angular web app.
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 #
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.

With the dependency injection, various elements could change automatically according to the trigger. YouTubeTV, Google Cloud, and Blispay are some popular apps that are built with Angular. React has a marginal edge over Angular in terms of performance. React is able to render complex UI components without any issues as it operates on a virtual DOM. Instead of updating all the viewable components, a React-based app only needs to render those affected by data changes.
Create a service worker with a default caching configuration. All attendees, speakers, sponsors and volunteers at our conference are required to agree with the following code of conduct.

This background script facilitates deep platform integration. It means that users can get all of the features they love about apps, such as offline support, rich caching, push notifications, and background sync. Let’s get an understanding of what progressive web apps are, how they can be made using the Angular framework, and the benefits of creating a PWA using Angular. Progressive web applications are mobile applications that do not require installation and depict behaviour similar to websites.
- YouTubeTV, Google Cloud, and Blispay are some popular apps that are built with Angular.
- What makes them different is that they are deployed on web servers through URLs.

We made use of Angular CLI and the Lighthouse to check if the PWA features are executed correctly. There are certain other things that you need to check manually rather than doing it using the Lighthouse. However, what is more important for you is to check that the PWA components are shareable and show high-performance. This command will add a non-transparent apple icon of 192 px square size. You can check the PWA feature test by running it again. It is an open-source analyzing tool developed by Google.
