Web Components: The Ultimate Guide from Zero to Hero

Master and build modern, framework-agnostic UI Kits using Shadow DOM, Custom Elements, Slots, Templates and beyond!

What you'll learn

• Master the Web Components API from scratch and understand why it’s the future of framework-independent frontend development.
• Build production-ready & reusable UI Kits using Shadow DOM, Custom Elements, HTML Templates, and Slots with zero framework dependencies.
• Integrate Web Components into Micro-Frontend architectures to make multiple frameworks work together on a single page.
• Apply advanced tools like TypeScript, Storybook, SASS, CSS Modules, Monorepos, and Unit Testing in real Web Components projects.
• Build accessible, form-associated custom inputs with full support for validation, styling, and native form behavior.
• Encapsulate styles and behavior to avoid global CSS conflicts and JavaScript collisions in complex frontend applications.
• Create framework-agnostic UI libraries you can reuse in React, Angular, Vue, Svelte, or plain JavaScript apps.
• Gain architectural confidence to design scalable, maintainable component systems for any frontend project.

Requirements

• No prior coding experience needed. I will guide you to Web Components API from level 0 to Pro
• All you need is a modern browser, a Code Editor like VS Code, and a desire to level up your frontend skills
• A basic understanding of HTML, CSS, and JavaScript will help, but it’s not mandatory
• You don’t need to know any UI frameworks or libraries like React, Angular, or Vue

Description

Ready to build modern, reusable, and framework-agnostic UI components that work everywhere?

This course is your ultimate hands-on guide to mastering the Web Components API — the native browser technology that lets you create high-performance, scalable frontend components with zero dependency on frameworks like React, Angular, or Vue.

Whether you’re working on a startup product, building a design system, contributing to open source, or preparing for a technical interview — Web Components are the secret weapon you need to build consistent, future-proof UIs.

What you’ll learn:

• How to confidently build Shadow DOM structures to fully encapsulate your HTML, CSS, and JS
• How to create, register, and manage Custom Elements with lifecycle callbacks and clean APIs
• How to use HTML Templates & Slots for dynamic, flexible, and reusable component structures
• How to master content projection and create multi-level slotting systems
• How to develop Form-Associated Custom Elements that integrate with native forms and validation
• How to connect Web Components with real-world apps across React, Angular, Vue, and Vanilla JS
• How to design and architect your own UI Kits, Design Systems, and Component Libraries
• How to use TypeScript with Custom Elements for type safety and IDE superpowers
• How to write Unit Tests for Web Components using modern tools and test strategies
• How to use Storybook to build isolated component environments and visual documentation
• How to manage complex projects using Monorepos (Yarn Workspaces) and share UI components across multiple teams and projects
• How to apply Accessibility (A11y) principles and make your components keyboard- and screen-reader-friendly
• How to implement Localization (i18n) inside Shadow DOM and manage language-specific content
• How to apply advanced styling options with CSS Modules, SASS, and CSS-in-JS (JSS)
• How to architect and deploy a Micro-Frontend platform where multiple frameworks live in harmony
• How to structure your components for performance, maintainability, and reusability in production
• And other countless tips, best practices, and real-world patterns you won’t find anywhere else

Whether you’re a complete beginner or a senior engineer, this course takes you from Zero to Hero, step by step.

You’ll build real-world projects, master native browser APIs, and gain practical skills used by tech leaders at Google, Meta, Amazon, and beyond.
