Textbook in PDF format This ebook helps you get the philosophy of Angular (currently 21.1.5), the new tools (like ES2015, TypeScript, Webpack, Angular CLI...), and each part of the framework in a pragmatic way. You will be able to kickstart your project by the end of the reading, and build your amazing apps! AngularJS is incredibly productive once you have mastered it. Despite all of this, it doesn’t prevent us from seeing its weaknesses. AngularJS is not perfect, with some very difficult concepts to grasp, and traps hard to avoid. Most of all, the Web has changed since AngularJS was conceived. JavaScript has changed. New frameworks have emerged, with great ideas, or better implementation. We are not the kind of developers to tell you that you should use this tool instead of that one. We just happen to know some tools very well, and know what fits the project. AngularJS was one of those tools, allowing us to build well-tested web applications, and to build them fast. Current versions: Angular: 21.1.5 Angular CLI: 21.1.4 A.1.
