This books shows all the steps necessary for the development of SPA (Single Page Application) applications with the brand new Angular 2 (still in beta). This book is in very preliminary stage, but if you are beginner in angular it will still serve the Understanding Angular 2 Component and module architecture. Download ebooks (pdf, epub, mobi) and read online. The Angular 2+ Notes for Professionals book is compiled from Stack Overflow Practical AngularJS.
The in-depth, complete, and up-to-date book on Angular 7. One tutorial says one thing and another says something completely different. Some teach the basics, but why is there nothing that shows how to fit all the pieces together? There are not many good screencasts or tutorials out there that teach how to maximize the framework. The vocabulary is foreign, how is a directive component different from a bare component?

Eric Elliott. This tutorial focuses on the new 3. The author has done a great job explaining what Single Page Apps are, how they work, and how to route them in a robust and secure way.
A more beginner-oriented lesson looking at different techniques for adding CSS styles to components. It shows you how to use component inline styles, style urls, and template inline styles, and explains the advantages behind each one. Here you can learn how to run Angular apps or components as web workers, allowing them to function in the background, independent from the main app thread.
Angular apps tend to get really big, and at some point the source files become too large to be loaded at once. Lazy loading allows us to speed up application load time by splitting it into multiple bundles, and loading them on demand. A deep dive into the greatly improved Angular2 dependency injection system and the different approaches behind the old and new DI. This article also has a second part , that further explains the host-child relationship and the visibility of dependencies.
The Angular2 change detection mechanism is much more transparent and easier to reason about than its equivalent in Angular 1.
However, there are still situations where you need to know exactly whats going on under hood. Angular is a very powerful and complex framework, and it's not surprising that it's footprint is also quite large. In this blog post you can learn various techniques, such as Tree-shaking and minification, that will drastically reduce the size of your final app. Observables in Angular 2 can be used for handling asynch code as an alternative to Promises.
They are a vast and complex topic, but this two-part tutorial does a great job of introducing them and showcasing their many use cases. An interesting take on design patterns for building Angular components.
The article goes through the components of a YouTube music player app and the relationships between them, with lots of code examples and explanations. NgUpgrade is meant to bridge the gap between Angular 1 and 2 by allowing code from both frameworks to co-exist in the same app.
This can greatly increase the size as both versions need to be included. You can learn how to reduce that extra footprint in this quick tip. In this article you will learn three different techniques that you can use to thoroughly test Angular 2 components. They are isolated testing, shallow testing, and integration testing. All three have their strengths and weaknesses and are best applied in certain scenarios. This guide gives a comprehensive overview of the various ways you can debug an Angular 2 applications using tools such as the Chrome DevTools, Angular Augury , simple JSON pipe filters, and the console itself.
Since we know many developers prefer interactive lessons, here are a couple of places where you can find excellent code walkthroughs and general Angular talks.
Although many of the lessons are for pro members only, there are still lots and lots of awesome free lessons you can watch. Adventures in Angular is a weekly podcast dedicated to the Angular framework. The panel cover a wide array of topics and it's probably the best place to get Angular news.
The archive contains over episodes, each at least 30 minutes long. Awesome one-hour-long course covering most of the basics. Although its beginner-oriented there are lots of things everyone can learn from this video in therms of project management and workflow.
A YouTube channel with lots of screencasts on web development and programming, with a focus on Angular 2 and its ecosystem of related technologies, tools, and languages. Another YouTube channel with a large collection of Angular tutorials, courses, code examples, and quick-tips. Last but not least, here are some resources that didn't fit any of the above categories, but can still be essential learning tools for any Angular developer.
The only completely free book on Angular 2 that we could find. To get the total number of items we can use the length property of the todos array. The first information which is printed out by the template is the total number of todo items available. Please be aware: We are using the new EcmaScript template string feature to assign a multiline string containing the template code. All todo items will be stored in an array of strings named todos. Writing your First Angular 2 Application 13 Template code of main component 1 template: For each iteration the current todo item is available through the variable todo.
For every element found in todos array the output of the element and its content is repeated. This is the syntax which is used in Angular 2 to create a variable todotext which is accessible in the component class and gives us access to the HTML element.
So the view implementation for our component is ready now. The class constructor is used to initialize the todos array with three items. Another thing to notice here is that the class keyword is preceded by export. The addTodo method is implemented in class AppComponent.
This notation is used in Angular 2 to describe events. By using the method System. The value which is assigend to the click event is a string containing an event handler method named addTodo. After the list of todos the template contains an input element and a button so that the user is able to add new todo elements. First we need to have an todos array in place containing all our todo items: Writing your First Angular 2 Application 14 listed in the declarations property of the NgModule decorator.
If you try to assign anything other as a string to the array the TypeScript compiler will run into an error because the type check fails.
Loading Components and Bootstrapping the Application Now we have nearly all pieces together to get our Angular 2 application up and running except one.
This method is not yet available and will be implemented in the next step. The method takes this string and calls the push method to extend the todos array with this new item.
The addTodo method gets one parameter: The last thing we have to do is to adapt the MyApp component class a little bit to meet the expectations the template code has set.
Herewith we make the AppComponent available as a module. Create the file and insert the following lines of code: Here we are using the previously assigned variable todotext and access the user input value by using the property value.
Writing your First Angular 2 Application 15 Importing modules and bootstrapping application in file main. To determine what needs to be displayed to the user. By executing platformBrowserDynamic.
Most of the NPM scripts are executed by using the npm command in the following way: Here you can see that the scripts section of package. This scripts installs the TypeScript definition files defined in typings..
Runs the TypeScript compiler one time. Runs the TypeScript compiler with option -w which enables the watch mode. After the initial compilation the compiler process stays active and listens for file changes.
Start the sample project by entering the project root folder on the command line and execute the NPM start script: In order to start our project with one single command TypeScript compiler and lite-server at the same time we simply need to execute: Writing your First Angular 2 Application Runs the static file web server lite-server. Uses concurrently to run the tsc: Everything which starts with  is outputted from the TypeScript server which is executed in watch mode.
Every line which is printed on the console is prefixed with either  or . Writing your First Angular 2 Application 17 Sample application of chapter 2 The output shows that both. Everything which starts with  is generated by lite-server.
The application is now up and running and can be opened by accessing URL http: With this information available you can see from which process the outputted line is generated. If you change HTML or TypeScript code in your project changes are processed by the running TypeScript compiler in the background and pushed to the browser automatically without the need of doing a manual refresh of the webpage.
