By: Prateek Jadhwani

Overview of this book

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.

Web Components Essentials and Specifications

Welcome to the world of Web Components.

Web Components, as the name indicates, are components that can be reused across different sections of a website by keeping encapsulation in check. They can even be published on the web, and be used by another site with the help of a simple import. This book covers all there is to know about Web Components. What they are made up of, how they can be used and in what scenarios. The book also covers wide variety of moderate and advanced level concepts such as good practices and integrating Web Components with other technologies.

In this chapter, we will talk about what Web Components are and how we can identify them while browsing various sites. We will also be talking about the specifications that make up Web Components along with detailed examples. You will be able to understand what custom elements are and how you can create one on your own. You will be able to encapsulate your Web Components with the help of a shadow DOM, and you will be able to use templates to achieve reusability.

While this chapter talks only about the basics of Web Components, by the end of this chapter you will be able to create your own Web Components from scratch, and understand the specifications associated with them.

In this chapter, we will cover the following topics:

  • Web Components
  • Web Component specifications
