Getting Started with Web Components

Types of life cycle callback methods

There are four life cycle callbacks available to Web Components as of now. These are as follows:

  • connectedCallback()
  • disconnectedCallback()
  • adoptedCallback()
  • attributeChangedCallback()

Let's discuss them in detail. 

connectedCallback()

This interface/callback gets invoked every time a copy of a Web Component gets added to the DOM. This is very useful when it comes to initializing events associated with the DOM inside the component, or state management (see Chapter 5, Managing States and Props), or anything that needs any sort of initialization or pre-checks.

Let's take a look at an example. In Chapter 1, Web Components Essentials and Specifications, we talked about a ...

Summary

In this chapter, we talked about what life cycle callback methods are and what purpose they serve. We talked about connectedCallback(), disconnectedCallback(), adoptedCallback(), and attributeChangedCallback(). We looked into various examples of how to use these callbacks and their practical uses.

In the next chapter, we will look into styling our Web Components with the help of CSS, and then we will talk about the gold standard checklist and its purpose.

Key benefits

  • Learn Web Components with more than 50 web component examples for both beginners and advanced users
  • Create responsive and highly customizable web pages using HTML, CSS, and JavaScript
  • Extend the potential of Web Components by integrating them with standard web frameworks

Description

Web Components are a set of APIs that help you build reusable UI modules that can operate in any modern browser using just Vanilla JavaScript. The power of Web Components lies in their ability to build frontend web applications with or without web frameworks. With this practical guide, you will understand how Web Components can help you build reusable UI components for your modern web apps. The book starts by explaining the fundamentals of Web Components' design and strategies for using them in your existing frontend web projects. You will also learn how to use JavaScript libraries such as Polymer.js and Stencil.js for building practical components. As you progress, you will build a single-page application using only Web Components to fully realize their potential. This practical guide demonstrates how to work with Shadow DOM and custom elements to build the standard components of a web application. Toward the end of the book, you will learn how to integrate Web Components with standard web frameworks to help you manage large-scale web applications. By the end of this book, you will have learned about the capabilities of Web Components in building custom elements and have the necessary skills for building a reusable UI for your web applications.

I’m no stranger to Packt’s typo laden and barely edited technical “books” — I knew that I’d encounter poor writing and worse editing when I placed my order.But wow. I didn’t realize it would be this bad.This book isn’t authoritative, complete, or intelligible. The quality is comparable to what you’d find on the fifth page of search results for “web components tutorial.” The only difference is that you’re paying $20 to read this one.I understand the challenges of writing a book, and I empathize with the author who is clearly passionate about the subject. The blame, in my opinion, falls entirely on Packt who failed to edit this book or coach the author.Stay away from this publisher.

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.
