A Progressive Web App (PWA) is a web application that uses modern web technologies to deliver an app-like experience to users. PWAs are responsive and fast, and can be installed on the user's home screen.
PWAs offer many benefits over traditional web apps, including improved performance, offline capability, and app-like features.
Angular is a popular framework for building PWAs. In this article, we'll show you how to create a PWA with Angular.
First, you'll need to create a new Angular project. You can do this using the Angular CLI.
Run the following command to create a new Angular project:
ng new my-pwa
This will create a new folder called my-pwa
with your Angular project.
Next, you'll need to add PWA features to your Angular project. You can do this using the @angular/pwa package.
First, install the @angular/pwa package:
npm install @angular/pwa --save
Next, add the PWA manifest to your index.html
file:
<link rel="manifest" href="/manifest.json">
Finally, generate a service worker file:
ng generate service-worker
This will create a file called ngsw-worker.js
in your src/
folder.
Now that you've added PWA features to your Angular project, you can test your PWA.
To test your PWA, you'll need to run a local server. The Angular CLI includes a development server, so you can use that.
Run the following command to start the development server:
ng serve
Now, open your browser and go to http://localhost:4200/. You should see your Angular app running.
To test the PWA features, you'll need to install the Lighthouse extension for Chrome.
Once you've installed Lighthouse, open the extension and click the "Generate report" button.
Lighthouse will analyze your app and provide a report. The report will tell you whether your app passes the PWA checklist.
If your app doesn't pass the checklist, try adding more PWA features. For example, you can add push notifications or background sync.
