Chrome Extension Mastery: Build Full-Stack Extensions with React & Node.js

Master the art of building production-ready, full-stack Chrome Extensions using modern web technologies and best practices. Learn how to build a powerful, feature-rich extension that seamlessly integrates with a separate React UI and communicates with a shared Node.js API.

Created by Ryan Fitzgerald

This course is everything I wish I knew when I started building Chrome Extensions almost a decade ago

This project-based course guides you through building a functional Chrome extension with a modern tech stack. We'll dive into advanced Chrome Extension concepts, set up permissions and authentication, structure a secure & scalable API with Node.js, and design a user-friendly React interface. By the end, you'll have a polished extension to showcase and the skills to build / deploy full-stack Chrome extensions for any project or client.

Some of the major topics covered include:

  • Building a UI using React and an API using Node.js / Express
  • Building a Chrome Extension that communicates with the UI and API
  • User authentication at the extension, UI, and API level
  • Advanced extension developement concepts (such as injecting React apps into webpages via Content Scripts)
  • Leveraging numerous Chrome Extension APIs (Actions API, Tabs API, and more) to create a seamless user experience
  • Deploying and publishing extensions, UIs, and APIs
  • And much more!
  • We'll also use a variety of tools, libraries, and technologies throughout the course:

    • Tools such as Docker, MongoDB Compass, Mailtrap, Postman, and more
    • Libraries and technologies such as React, Node.js, Express, MongoDB, Vite, Styled Components, Nodemailer, and more

Who's this course for?

This course is perfect for developers of various skill levels wanting to dive into full-stack Chrome extension development. With a basic understanding of JavaScript (and ideally React), frontend, backend, and full-stack developers can tackle this hands-on, practical course.

New to extension development entirely? No problem — each section offers clear guidance and explanations to keep you on track and ensure the pace is just right, so prior extension experience isn't strictly required.

What are we going to build?

In this course, we'll build a feature-rich Chrome extension inspired by Pocket, where users can save, update, delete, and tag links for easy organization and retrieval. This full-stack project includes both frontend and backend development: a UI and extension both built with React, as well as a Node.js/Express backend API with MongoDB for managing link storage, updates, and retrieval. Users will also be authenticated at all 3 levels.

We'll follow best practices for building scalable, maintainable UIs and APIs, and the extension component will incorporate advanced design patterns like authentication, preparing you to build sophisticated, production-ready extensions on your own. You can also view a walkthrough of the app in the welcome lesson preview.

What are students saying?

While this course is not yet released, here's what past students have said about my teaching style and support in other training courses I have created. These testimonials reflect the quality, depth, and hands-on approach you can expect in this course too.

  • Great class, exactly what I was looking for. Code was not too simple for an experienced developer to understand.

  • This was incredibly easy to follow, code, with minimal errors on my end. Ryan was very easy to understand. This is one of the few courses I've completed and I will gladly check out any new courses if he makes more.

  • Very good course. You can learn very quickly to write extensions for Chrome. The instructor explains everything very well and he responds very quickly to questions in the Q&A section. Highly recommended if you want to start to write chrome extensions!

Ryan Fitzgerald – Hey there, I'm the author behind this course.

With a decade of experience building Chrome extensions and scalable web applications under my belt, I bring a deep understanding of the Chrome extension ecosystem.

I've developed and published multiple Chrome extensions in the Web Store, reaching thousands of active users and refining best practices along the way. I also created ExtensionKit, a comprehensive toolkit of examples and boilerplates designed to simplify extension development. My Chrome Extension fundamentals course on Udemy has become one of the highest-rated in the category, helping hundreds of students gain confidence with Chrome extension development.
