Web Components in Action

Summary

Web Components are a standardized way to build reusable custom elements for web pages and applications using HTML, CSS, and JavaScript. A Web Component is well-encapsulated, keeping its internal structure separate from other page elements so they don’t collide with the rest of your code. In Web Components in Action you’ll learn to design, build, and deploy reusable Web Components from scratch.

About the Technology

The right UI can set your sites and web applications apart from the ordinary. Using the Web Components API, you can build Custom Elements and then add them to your pages with just a simple HTML tag. This standards-based design approach gives you complete control over the style and behavior of your components and makes them radically easier to build, share, and reuse between projects.

About the Book

Web Components in Action teaches you to build and use Web Components from the ground up. You’ll start with simple components and component-based applications, using JavaScript, HTML, and CSS. Then, you’ll customize them and apply best design practices to maximize reusability. Through hands-on projects, you’ll learn to build production-ready Web Components for any project, including color pickers, advanced applications using 3D models, mixed reality, and machine learning.
