Getting Started with Web Components

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.

Figuring out reusable Web Components

The main page of the web app we're aiming to create might look something like this:

This page shows that there is a header on top, an input field and a button that can be used to search a string, and a set of results. When we break this page into a set of components, the component list looks something like this:

  • Header component: A header that can be used on all pages. It needs to be sticky on the top, and clicking on the links should change the URL.
  • GIF cover component: A component that takes a URL as an attribute and shows it. It can also have a height limit. 
  • Search bar component: A component that is responsible for getting input from a user and searching for a string with the help of APIs. And when the search is complete, it returns the results with the help of a custom event.
  • Search container: A component that will have a Search...
