Progressive Web Apps (PWAs) unite the best of web and native app functionality: speed, offline capability, home-screen installability, and push notifications without distributing it through the app store. Angular provides native support for PWAs, streamlining and speeding up the process of building a reliable user experience like that of an app.
1. Service Workers & Offline Capability
Angular comes with built-in service worker capability that enables offline access via resource and API response caching. Developers control caching with the ngsw-config.json file. This file lets you set rules so key assets stay available offline. Background sync ensures updates happen automatically when the network is restored—no user action required.
2. Installable experience
The command ng add @angular/pwa creates a Web App Manifest file for the developer automatically, which defines things like the app name, icons, theme colors, start URL, and display mode. Once the user installs the app, it opens in standalone mode—minus the browser UI—deliver a true-app experience quickly and easily from the home screen.
3. Push Notifications
Your application can allow users to subscribe to push notifications throughAngular’s SwPush service. When users subscribe, they will receive interactive notifications via their browser’s push service, enabling engagement with users in real-time even if your application is not open. This is ideal for sending updates, alerts, or reminders.
4. Native-like UX
Using Angular’s modular architecture, lazy-loading, and routing mechanism, you can present transitions that are indistinguishable from native app experiences. Coupled with service workers, background sync, and transitions where the user waits for something to happen (and animations), it is possible to provide a UX that is frictionless, flicker-free and has a responsive feel.
5. Background Updates
Angular service worker provides a system to fetch updates in the background, and when a user next visits your application, they automatically have the latest version of the app—no need to refresh. This means your PWA can be recent, contemporary, and secure.
Business Advantages
- Greater User Engagement
Faster load times and the ability to work offline has reduced bounce rates and enhanced the likelihood of users returning. - One Codebase For Everyone
A single Angular project can provide a seamless experience for users on desktop, mobile web and installed app experiences. This has reduced development time and ongoing maintenance costs. - Dodge App Stores
You can avoid the lengthy review processes of app stores, extensive travel time to stores, and any fees caused by app stores when you deploy directly via the web. - SEO Friendly
Unlike native apps, pwAs are crawlable by search engines
