Video: How the Shadow DOM has Got You Covered?

Web Components are a piece of reusable UI enabled by web standards and built into the web platform. They offer the potential for faster component initialization and less library overhead. Web Components can be created from scratch and utilized with existing component libraries. Shadow DOM and Declarative Shadow DOM provide benefits such as scoped CSS and server-rendered components. The tradeoff between not repeating oneself and achieving full server-side rendering support is discussed. User experience is deemed more important than developer experience.

Today's Talk introduces Mitosis, an open source project that solves the problem of building framework agnostic components. It supports JSX and Svelte syntax and outputs human-readable code for various web frameworks. Mitosis is already being used by enterprise customers and can be easily integrated with React, Svelte, and other frameworks. It saves time, allows for easy handling of framework version migrations, and enables efficient unit and integration testing.

Web Components and the Lit library are introduced, highlighting their ability to create custom elements and replicate built-in components with different functionality. The use of semantic HTML and the benefits of web components in development are emphasized. The features of Lit, such as data binding and rendering, are discussed. The Santa Tracker is showcased as an example of web components being used in educational games. The compatibility of web components with other frameworks and their versatility in creating small widgets or large applications are highlighted.

This Talk by Tony Alicia focuses on authoring HTML in a JavaScript world. The speaker challenges developers to change their approach to building React components by starting with HTML first. By authoring HTML in a semantic way, readability and maintainability can be improved. Well-authored HTML provides better understanding of content and improves accessibility. It also has performance benefits by reducing DOM size. Investing time in HTML can save time and make applications more future-proof.

Today's Talk discusses immutable web apps and their benefits, such as faster loading times and easy version tracking. The use of Universal Module Definition (UMD) style bundling allows for flexible dependency management and gradual upgrades. Tools like Webpack and Rollup provide ways to reference UMDs in bundles and automate dependency configuration. Arborist and YAML files help resolve dependency trees and handle conflicts, while the Orchard CLI tool automates dependency ordering. Internal and external dependencies can be initialized and managed effectively for optimal performance.

Web components allow you to create your own HTML elements that can do anything you want, and they are supported by all modern browsers. Many companies, including YouTube and GitHub, use web components to enhance their websites. There are extensive tooling and libraries available for web component development. The Model Viewer Web Component enables the display of 3D models in Virtual and Augmented Reality without needing to know underlying technologies. Web components can be used with various frameworks and libraries, and there are resources available to help with compatibility.
