This book does not teach Ionic as a box of unrelated components. It builds one application, BoB Tours, the app of a fictional tour company in Bonn, step by step, and lets each new concept solve a real problem when that problem appears.

What you build along the way

A project from ionic start, pages to move between, and live data from a server with httpResource()
Ionic's UI components, each one moving the app forward, and arranged so the chapter doubles as a catalog
Forms with Signal Forms, theming and dark mode, and layouts that use the space of phone, tablet and desktop
Accessibility: headings and landmarks, keyboard, text size, contrast, and automated checks with axe
Native features with Capacitor 8 on iOS and Android, including a life without a connection
Debugging, tests with Vitest, and the way out: signing, the iOS archive, a PWA and a pipeline on GitHub Actions

Two bonus chapters follow. Ionic with or without frameworks helps you choose between Angular, React, Vue and none at all. Ionic and AI adds a form assistant to the app without handing its key to the phone, and then asks what a coding assistant builds for you, and when that actually pays off.

The modern stack. Standalone components, Signals, zoneless change detection, OnPush and Vitest, used where they earn their place. The examples are not based on remembered behavior: starters, builds, navigation, network requests and tests were checked against the real toolchain while the book was written.

What you need. HTML, CSS and JavaScript. Not Angular, TypeScript or experience building apps; those are what the book is for. The chapter on Angular is written to be returned to, so if you already know it, start with the first app.

The code. The app's state along the way lives in a public GitHub repository under the MIT license, so you can compare your code or join at any point.

This edition is an accessible PDF (PDF/UA-2): navigable headings, and a text alternative for every figure.

Earlier editions of this series were called \"practically unrivaled\" by c't and \"one of the best Ionic books of all time\" by BookAuthority, and they are used in university courses from Arizona to Brunei.
