Create an Angular application
The first step in building a PWA with Angular is to create an Angular application using the Angular CLI. The Angular CLI provides developers with a set of tools that streamline the development process and make it easier to create Angular applications. To create this application, run the following command:
ng new my-app
This will create a new Angular application with the name ‘my-app’.
Install and configure the ‘@angular/service-worker’ package
The ‘@angular/service-worker’ package provides developers with the tools necessary to add service worker support to their applications. Service workers are a key component of PWAs and enable offline support, background sync, and push notifications. To install and configure the ‘@angular/service-worker’ package, run the following command:
ng add @angular/pwa
This will install and configure the ‘@angular/service-worker’ package and add the necessary files to your application.
Update the manifest file
The manifest file is a JSON file that provides information about the PWA, such as its name, icon, and theme color. To update the manifest file, open the ‘src/manifest.json’ file and update the values according to your preferences.
Add a service worker to cache assets
The service worker is responsible for caching the assets required for the PWA to work offline. To add a service worker to your application, open the ‘ngsw-config.json’ file and update the ‘dataGroups’ object to include the assets you want to cache.
Add a home screen icon and splash screen
To provide a better user experience, it is important to add a home screen icon and splash screen to the PWA. To add a home screen icon, place a 512×512 PNG file named ‘icon.png’ in the ‘src/assets’ folder. To add a splash screen, place a 1920×1080 PNG file named ‘splash.png’ in the ‘src/assets’ folder.
Test and deploy the PWA
Once the PWA is built, it is important to test it thoroughly on different devices and platforms. To test the PWA, run the following command:
ng serve –prod
This will serve the PWA on a local server. To deploy the PWA, you can use any hosting service that supports HTTPS.
Building Progressive Web Apps with Angular is a straightforward process that requires developers to follow a few simple steps. By leveraging the tools and features provided by Angular, developers can create robust PWAs that work seamlessly on any device and platform. With the growing popularity of PWAs, it is important for developers to master the art of building PWAs with Angular to stay ahead of the curve
