Developing Progressive Web Applications with Angular (and Ionic)

Ready to put your Angular app on users' home screens, without app store fees, review queues, or rejection letters?

Developing Progressive Web Applications with Angular (Second Edition, 2026) is the hands-on path from deployed web app to installable PWA. You follow the open-source Ends Well sample on GitHub, from ends-well-no-pwa through ends-well-pwa to ends-well-updates, or apply the same steps to your own Angular project.

Author Michael D. Callaghan has shipped software since 1995. He walks experienced web developers through Angular 22, ng add @angular/pwa, offline caching with ngsw-config.json, Lighthouse audits, home-screen install, custom splash screens, and the modern SwUpdate.versionUpdates flow, not slide-deck theory.

Your app is built. The store is the bottleneck. This book removes it.

In this book you'll discover how to

• Host on HTTPS and prove PWA readiness with Lighthouse, so you know you're ship-ready before users arrive
• Add @angular/pwa and configure offline mode, so your app keeps working when the network drops
• Cache APIs and images with dataGroups, so repeat visits feel instant, not sluggish
• Ship install prompts, icons, and splash screens, so users get a real app on their home screen
• Push updates with VERSION_READY, so you ship on your schedule, not Apple's or Google's

This Second Edition includes honest iOS PWA guidance, expanded hosting and performance notes, and pointers to push notifications, Trusted Web Activities, and Capacitor when a PWA is not enough.

Developing Progressive Web Applications with Angular is the practical guide for TypeScript developers who already have an Angular app and want mobile and desktop reach from one codebase, without maintaining separate native projects.

If you want commands, file names, and working sample code, not another "PWAs are great!" keynote, follow Ends Well and ship.
