دانلود کتاب Angular مدرن

When I started my career in the spring of 2016, Angular, as we know it today, did not yet exist; instead, I used to be an Angular.js developer—a long-forgotten framework that has now reached its end of life. While it offered interesting features and an opportunity to build more organized web apps, it did have some glaring flaws. This brings us to September 2016, when Angular 2 or, as it is known now, simply Angular was released. This was huge! Everything changed at a moment’s notice: we now had TypeScript, classes everywhere, strict organizational rules, and, soon enough, even a dedicated CLI tool to manage over applications. Of course, this was overwhelming at first; however, upon further research, it was revealed that the framework is actually very solid and an immediate upgrade upon anything we had prior, and that was the moment when many frontend developers, including myself, fell in love with it. Of course, this new Angular, like any other tool, wasn’t without flaws either: so began the process of continuous improvements upon the framework that we know and love. In the few first versions the framework stabilized, then in versions 8 and 9, we got a new rendering engine, and now we get a new phase of massive improvements that are often referred to (even by the Angular core team itself) as the “Angular renaissance.” I was always very involved with the progress and in-depth characteristics of Angular in the sense of documenting them. I loved going to the Angular source code and trying to figure out how the most interesting features actually work, trying out the most challenging problems, and speaking to industry experts. What I discovered is that, for me, the best way to learn something is to write about it. I started writing articles about Angular, going to podcasts, and in 2019 even began public speaking. All of this in the end culminated in this book. But why have this book at all? Well, when this first began, we as a community didn’t know anything about the “Angular renaissance”—we just knew Angular had scheduled major releases every six months, and with every release, we got some small new interesting things. However, we noticed that the changes incrementally got more and more revolutionary, so to speak; it was useful to write articles about all the features or talk about them at podcasts and events, but it kept growing and growing, with more changes that necessitated a very thorough exploration. Then it became obvious that something more was necessary. And that is how this book came to be: a book that is meant to help Angular developers who are excited about these new changes, or maybe frightened by them, to understand the new features, appreciate them, use them in their new projects, or even migrate older projects toward a more modern approach. The book cannot possibly claim to be a complete guide to everything new in Angular; as I write these words, Angular keeps changing and growing. During the writing of the book, I had to go back and change some things that were no longer current; this is the nature of software development, and the only thing we can do is keep learning. I know I learned a lot while writing this book, and I hope it will help you learn a thing or two about modern Angular too.
