Getting Started with Web Components

Book description

Explore modern Web Component design and integrate them with a variety of web frameworks to build encapsulated reusable UI components for your web apps

Key Features

  • 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

Book 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.
