Web Components Demystified
- Scott Jehl released a course called Web Components Demystified, focusing on teaching about web components to clear up any confusion surrounding them.
- Web components are a set of technologies where HTML, CSS, and JavaScript work together to create custom elements that behave as desired.
- They include custom elements, HTML templates, and Shadow DOM; HTML Imports, a fourth ingredient, have been removed.
- Web components, unlike React components, are literal HTML elements that must adhere to HTML rules.
- Custom elements in web components allow developers to define an element's behavior using various lifecycle methods like constructor and connectedCallback.
- HTML templates in web components are for developers, allowing the creation of reusable markup that generates more markup.
- Shadow DOM in web components encapsulates markup, scripts, and styles to prevent them from affecting other DOM elements.
- Scott Jehl's course and notes focus on key concepts like custom elements, HTML templates, Shadow DOM, and the lifecycle methods of web components.
- Other topics covered include Custom Elements API, adopting elements, element styling, and using external stylesheets in web components.
- The article also discusses popular web components frameworks and libraries like Lit, webc, Spectrum, FAST, and Shoelace.
