This succinct, advanced-level guide to Angular Signals is built around a real-life shopping cart application designed for experienced Angular developers who want to level up their skills and see how to implement Signals in complex, production-grade applications. Through the creation of a shopping cart app, you will explore how to model application state with Signals, manage side effects, and integrate Signals into key Angular features such as HTTP APIs, routing, guards, directives, and more. The book begins with establishing the application structure for scalability and then moves on to modelling product and cart state with Signals. This is followed by a chapter on Effects, APIs, and Async Data with Signals. The book then moves on to discussing component communication and Routing, Guards and Auth. The penultimate chapter deals with performance, testing and debugging of the shopping cart application that you will have learnt how to create. The final chapter involves patterns for migrating from RxJS or NGRX to Signals. The book is a must-have if you are seeking to move beyond tutorials and into real-life implementation of Signals in scalable commercial applications.
What You Will Learn Architect a Signals-first Angular application - Apply Signals in routing, guards, directives, and UI communication patterns
- Migrate existing services or RxJS patterns to Signals
- Test and debug Signals-heavy applications confidently
Who This Book Is For Experienced Angular developers, tech leads, and architects who want to learn how to integrate Signals into their applications for both new and existing projects.
這本簡潔的高級指南《Angular Signals》圍繞一個現實生活中的購物車應用程式，專為希望提升技能並了解如何在複雜的生產級應用程式中實現 Signals 的經驗豐富的 Angular 開發者而設計。通過創建購物車應用程式，您將探索如何使用 Signals 建模應用程式狀態、管理副作用，並將 Signals 整合到 Angular 的關鍵功能中，例如 HTTP API、路由、守衛、指令等。本書首先建立可擴展性的應用程式結構，然後進入使用 Signals 建模產品和購物車狀態。接下來的一章將討論使用 Signals 的效果、API 和異步數據。然後本書將討論組件通信、路由、守衛和身份驗證。倒數第二章處理您將學會創建的購物車應用程式的性能、測試和除錯。最後一章涉及從 RxJS 或 NGRX 遷移到 Signals 的模式。如果您希望超越教程，進入可擴展商業應用程式中實際實現 Signals，這本書是必備之選。
您將學到什麼
- 設計以 Signals 為主的 Angular 應用程式
- 在路由、守衛、指令和 UI 通信模式中應用 Signals
- 將現有服務或 RxJS 模式遷移到 Signals
- 自信地測試和除錯以 Signals 為重的應用程式
本書適合誰
本書適合希望學習如何將 Signals 整合到新舊項目中的經驗豐富的 Angular 開發者、技術負責人和架構師。
