Web Components: The Ultimate Guide from Zero to Hero
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.
- Publish projects of any complexity to NPM & Github
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
How to publish projects of any complexity to NPM & GitHub
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.

Hi, my dear student! My name is Andrew.
I’m a Certified International IT Jury, Engineering Manager, Architect, Lead Full-stack Developer, and Passionate IT Mentor with 10+ years of versatile professional experience. Embarked on my programming journey from early school days. Obtained Bachelor's and Master's Degrees in Computer Science and Software Engineering.
I have profound expertise in Javascript, Node.js, Databases, System Design, and AWS. I do have the heart for Web Development and Engineering Management. But I've also worked extensively on creating hybrid Mobile & Smart TV apps, DevOps, Delivery & Resource Management, Software Architecture, and Interviewing. I also used to code apps in Java (Spring & Vertx), ASP Net C#, PHP, C/C++, and more. So I've got a lot to share.
Throughout my career, I have conducted more than 2,000 individual mentorship sessions with people of all technical levels worldwide, not to mention thousands of my beloved students on Udemy and other platforms.
I'm a multiple-time finalist and winner of the international and annual programs, including but not limited to:
* Stevie Awards for Great Employers
* Stevie Awards for Technology Excellence
* Globee Awards for Leadership
* Globee Awards for Information Technology
* Globee Awards for Business
* Mentor of the Month in the Spotlight at WomenGoTech
On top of that, I’m a member of various international IT associations and guilds and a certified IT judge. Occasionally I'm invited to take part in worldwide IT-events (awards, conferences, hackathons), where I evaluate and nominate innovative solutions, breakthroughs, and achievements of individuals, start-ups and giant tech companies around the world (US, EU, UK, Canada, India, China, etc):
* Duke University
* Globee Awards
* DevPost / MLH
* Orpetron
* WomenGoTech
* TurtleHacks
* HackClub
* and many more
I’m a technical publications writer. I have expert pubs in science journals on Web & Smart TV development and coding articles on HackerNoon, DevMedia, and other platforms.
These endeavors have laid the foundation for co-founding the prosperous IT Start Up, where in my role as CTO, I have nurtured an effective technical team of over 30+ professionals.
I'm the founder of CodeLikeAndrew-io Tech Community which connects talented people from the whole world in one place.
I'm full of drive, motivation, aspire, and crave to learn and teach new. I reckon that it’s not school education that is paramount in building a person, but a life attitude and the ability to constantly work on oneself and make mistakes.
Throughout my career, I elaborated my own methods for software development, self-growth, time and task management both at work and personal life, refining company processes, code reviewing, hiring, and mentoring.
I’ll be glad to convey my fighting spirit, passion, and energy, bring new fresh ideas on various challenges, and share my invaluable life and professional experience.
