Angular Cookbook

Chapter 2: Understanding and Using Angular Directives

In this chapter, you'll learn about Angular directives in depth. You'll learn about attribute directives, with a really good real-world example of using a highlight directive. You'll also write your first structural directive and see how ViewContainer and TemplateRef services work together to add/remove elements from the Document Object Model (DOM), just as in the case of *ngIf, and you'll create some really cool attribute directives that do different tasks. Finally, you'll learn how to use multiple structural directives on the same HyperText Markup Language (HTML) element and how to enhance template type checking for your custom directives.

Here are the recipes we're going to cover in this chapter:

  • Using attribute directives to handle the appearance of elements
  • Creating a directive to calculate the read time for articles
  • Creating a basic directive that allows you to vertically scroll to an element
  • Writing your first custom structural directive
  • How to use *ngIf and *ngSwitch together
  • Enhancing template type checking for your custom directives

Technical requirements

For the recipes in this chapter, make sure you have Git and Node.js installed on your machine. You also need to have the @angular/cli package installed, which you can do with npm install -g @angular/cli from your terminal. The code for this chapter can be found at https://github.com/PacktPublishing/Angular-Cookbook/tree/master/chapter02.

Description

The Angular framework, powered by Google, is the framework of choice for many web development projects built across varying scales. It’s known to provide much-needed stability and a rich tooling ecosystem for building production-ready web and mobile apps. This recipe-based guide enables you to learn Angular concepts in depth using a step-by-step approach. You’ll explore a wide range of recipes across key tasks in web development that will help you build high-performance apps. The book starts by taking you through core Angular concepts such as Angular components, directives, and services to get you ready for building frontend web apps. You’ll develop web components with Angular and go on to cover advanced concepts such as dynamic components loading and state management with NgRx for achieving real-time performance. Later chapters will focus on recipes for effectively testing your Angular apps to make them fail-safe, before progressing to techniques for optimizing your app’s performance. Finally, you’ll create Progressive Web Apps (PWA) with Angular to provide an intuitive experience for users. By the end of this Angular book, you’ll be able to create full-fledged, professional-looking Angular apps and have the skills you need for frontend development, which are crucial for an enterprise Angular developer.

Who is this book for?

Angular Cookbook comes up with a lot of updates and new feature's. For example, Angular Materials, State Change, etc, etc. All these core concepts explained really well. The interesting feature about this book is - It has given enough examples and elaborates each topic with it's usage. One must read this book to get hands on real world usage of core concepts of Angular.Author has core knowledge on Angular concepts and he's also a Google Developer Expert.I recommend this book to all the Angular freaks over there.

Angular Cookbook is a great resource for new and experienced Angular Developers alike. What the book excels at is showing common patterns and boilerplate for intermediate and complex topics. This is the sort of book that I would turn to if I need to implement something complex that I have not implemented before, or if I need to look at a code sample for something that I do infrequently.My favorite section in the Angular Cookbook is its section on animations. Animations are a great way to provide reactivity and fluidity to a web app, but they can be somewhat daunting to write for newer Angular developers. The Angular Cookbook provides code samples for animating components, but takes it one step further by explaining how a given code sample works and what the sample is doing. Providing extra context like this is critical for newer developers to learn and fully understand what they're doing.The only thing I could see that might be improved in this book is that there are unnecessary references to VS Code in several of the Getting Started sections. This isn't a major issue: using any IDE is fine. However, since the book doesn't use any plugins, snippets, or VS Code-specific features, I don't see much of a reason why VS Code would be mentioned explicitly. A newer developer may get a bit confused by this and go out of their way to install additional software that may not be necessary if they already have an editor of choice.Overall, this is a stellar book that all Angular developers would benefit from having on their bookshelves.

What is custom duty/charge? Chevron down icon Chevron up icon

Customs duty are charges levied on goods when they cross international borders. It is a tax that is imposed on imported goods. These duties are charged by special authorities and bodies created by local governments and are meant to protect local industries, economies, and businesses.

Do I have to pay customs charges for the print book order? Chevron down icon Chevron up icon

The orders shipped to the countries that are listed under EU27 will not bear custom charges. They are paid by Packt as part of the order.

List of EU27 countries: www.gov.uk/eu-eea:

A custom duty or localized taxes may be applicable on the shipment and would be charged by the recipient country outside of the EU27 which should be paid by the customer and these duties are not included in the shipping charges been charged on the order.

How do I know my custom duty charges? Chevron down icon Chevron up icon

The amount of duty payable varies greatly depending on the imported goods, the country of origin and several other factors like the total invoice amount or dimensions like weight, and other such criteria applicable in your country.

For example:

  • If you live in Mexico, and the declared value of your ordered items is over $ 50, for you to receive a package, you will have to pay additional import tax of 19% which will be $ 9.50 to the courier service.
  • Whereas if you live in Turkey, and the declared value of your ordered items is over € 22, for you to receive a package, you will have to pay additional import tax of 18% which will be € 3.96 to the courier service.
