Course Code for What is React on Pluralsight
Updated Course: What is React (Released January 2025)
This course has been updated to reflect the latest changes in React 19 production. It includes completely a completely new discussion around using React Server Components with Suspense and promises*. This includes running React Server Components where the data is retrieve and rendered in the Node server, as well as the very powerful scenario where the data is downloaded in the node server, and then automatically sent to the React client without ever having to go through an REST server.
All examples in this repository are converted to React 19.0.0 production.
The new Clips are Module 4, Clip 9 and Clip 10. Both, completely new

The main branch here is the latest updates to the Pluralsight course What Is React. This GitHub repo includes the final code for all the modules in the course.
This course will teach you what React is, and help you understand why React is the number one JavaScript library for building JavaScript Apps in a browser.
In this course, What is React, you’ll learn all about the component based nature of React and how that translates into highly performant and easy to use web applications.. First, you’ll explore the nature of React and fundamentally how it addresses building component based web apps.. Next, you’ll discover more specifically how React is based on a virtual DOM that efficiently maintains the applications user interface to mirror that Virtual DOM. Finally, you’ll learn how React uses the powerful JSX syntax to represent components and the actual UI of a running web app.. When you’re finished with this course, you’ll have an excellent understanding of why React is the most popular JavaScript library for building web apps, as well as what it takes to build a React app.
- Install Node 18.17 or later.
- Clone this repository. -
https://github.com/pkellner/pluralsight-what-is-reactor download the zip - **Set your default directory to which module you want (example:
cd m3-hands-on-moving-to-concurrent-rendering-cd m4-hands-on-with-the-new-react-hooks - Install Node Packages with Dependencies. -
npm install
Each of the folders here represent one module of the course. In each folder, there are subfolders that represent the completed code at the end of each clip. Where this is no clip reference, either there is no code in that clip or nothing changed from the previous clip.
Once in a clip directory, the easiest way to test the app is to first install the packages by typing at the root of that directory (in a terminal window or DOS prompt)
npm install
Then, do run the app you just need type
npm run dev
That will launch the web server on port 3000 where you can browser to it at the url: http://localhost:3000
