Web Components & Stencil.js - Build Custom HTML Elements
Without frameworks like Angular, libraries like React or expert JavaScript knowledge in general. Just with a magic, native-JavaScript feature called "Web Components" (or "custom HTML elements"). Web Components are a combination of various specifications that are baked into the browser. Getting started with these features is a breeze and you'll quickly be able to build your own powerful and re-usable (even across projects!) custom HTML elements.

Such custom elements don't replace Angular, React or Vue though - instead you can easily use them in ANY web project, including projects using such frameworks and libraries.
In this course, you'll learn this from scratch.
But we won't stop there. Whilst getting started is fairly easy, more complex components will be more difficult to create. Stencil.js is a tool that makes the creation of such native web components much easier by using modern features like TypeScript and JSX (don't know that? No worries, you'll learn it in the course!).
In detail, in this course you will learn:
how to build re-usable, lightweight custom HTML elements with native browser features
how to build web components of all complexities - from a simple tooltip to modals or side drawers
how to pass data into your own web components and use it there
how to emit your own custom events which you can listen to in JavaScript
how to use the Shadow DOM to scope your CSS styles to your custom elements
how to use Stencil.js to get a much easier development workflow
how to use the many features Stencil.js provides to build native web components way more efficiently
how to deploy/ re-use your own web components in ANY project using ANY JavaScript framework like Angular, React or Vue (or none at all!)
Prerequisites:
Basic JavaScript knowledge is a must-have
ES6 JavaScript knowledge (const, let, classes, ...) is strongly recommended but not strictly required - a brief refresher is provided as part of the course
NO JavaScript framework knowledge (e.g. Angular, React, Vue) is required
NO TypeScript or JSX knowledge is required
Let's dive into this exciting technology together!
- Everyone who's interested in building custom HTML tags!
- Students who want to dive into a future-proof web technology that can be used in any web app
