Fundamentals of Web Components

Web applications are evolving and frameworks like react, vue, angular, svelte and others, are bringing functionalities like reusable components to make it easier to create huge applications. With web components we can create our custom html elements, just like we do in the other popular web frameworks. But the difference is, web components api is web standard, which means it's coming with the modern browsers. So without requiring additional build process or any other tooling, we can run our code as it is in the browser. All we need is just vanilla javascript knowledge.

Web components has three main APIs. Custom Elements, Shadow DOM and HTML Templates. And in this course we will learn and practice all.

We will learn how we can built custom elements, how we can extend built-in elements. Also we will practice the "template" to make the rendering of our custom element more efficiently.

We are going to practice the Shadow Dom to see it's role in web components. We will see how we can compose our custom element with the markup provided externally. And also we will see our styling options of our elements.

And finally, we will practice, how the events are changed in shadow dom. We will see the issues and we will introduce our solutions.

If you want to build re usable web components without relying onto a third party library, if you want to build applications based on the web standards, then web components is the answer.
