This free course focuses specifically on building Chrome extensions with a modern web stack — TypeScript, React, and Webpack alongside standard JavaScript and HTML/CSS — rather than the older, purely vanilla approach most extension tutorials still use.

How it's structured

It starts simply enough that you can have your first working extension built within the first hour, then layers in more advanced tools and techniques from there. Along the way you'll cover the fundamentals of how Chrome extensions work, set up a Webpack build system to bring React and TypeScript into an extension project, use basic Git and NPM from the command line, and pull in component libraries like Material UI to build interfaces quickly.

What you'll build

Three complete extension projects built step by step, including data fetching from third-party APIs — and because the stack is standard modern web tooling, the skills carry over directly into general web development, not just extension work.

The course is designed flexibly for students of all levels, covering everything from the very basics of extensions to more exciting new technologies! The first part of the course is designed to help you hit the ground running so that you can develop your very first extension within the first hour of the course. Then, we begin introducing more advanced concepts, technologies and projects to supercharge your extension development skills.

Throughout the course we cover a ton of concepts and technologies:

  • Comprehensive overview of the fundamentals behind Chrome Extensions

  • Building extensions using the standard approach with JavaScript, HTML and CSS

  • Designing a Webpack build system to enable the use of React and TypeScript in your extension

  • Basic usage of Git and NPM on the command line

  • Using design system component libraries like Material UI to build beautiful UIs quickly

  • Building three large extension projects step-by-step from scratch

  • Data fetching using HTTP requests to third party APIs

  • Deploying your completed extension to the Chrome Web Store for real users

Who teaches React & TypeScript Chrome Extension Development [2021]? Udemy

Udemy thumbnail

Udemy is the largest open marketplace for online courses on the internet. Founded in 2010 by Eren Bali, Oktay Caglar, and Gagan Biyani and headquartered in San Francisco, the company went public on the Nasdaq in 2021 under the ticker UDMY. The platform hosts well over two hundred thousand courses across software development, IT and cloud, data science, design, business, marketing, and creative skills, taught by tens of thousands of independent instructors. Roughly seventy million learners use it worldwide, and the corporate arm — Udemy Business — supplies a curated subset of that catalog to enterprise customers.

Because Udemy is a marketplace rather than a single editorial publisher, the catalog is uneven by design. The strongest material lives in the long-form, project-based courses authored by working engineers — full-stack JavaScript, React, Node.js, Python data science, AWS, Docker and Kubernetes, mobile development with Flutter and React Native, and cloud certification preparation. The CourseFlix listing under this source is the slice of that catalog that has been mirrored here for offline-friendly viewing, organized by topic and updated as new releases land. Pricing on Udemy itself swings dramatically with the site's near-permanent sales, which is why the platform is best treated as a deep reference catalog: pick instructors with strong reviews and a track record of updating their material rather than buying on the headline price alone.
