- Introduction You’ve created your first React app using Create React App! Now, let’s explore the project structure and understand the purpose of each file and folder. Our friendly duo, Geek and Gal, will guide you through this process.
Ready to dive into the project structure of a React app? 😃
Sure, let's go!
- Understanding the Project Structure
When you create a new React app using Create React App, it generates a bunch of files and folders for you. Let's look at the main ones.
First, there's the
public
folder. It contains the static files for your app, like the
index.html
file.
Got it! The
public
folder is for static files!
Right! Next up is the
src
folder. This is where you'll write your React components and JavaScript code. Inside, you'll find the
App.js
file, which is the main component of your app.
So, the
src
folder is where the magic happens? 🧙♂️
Exactly! You'll also find a
index.js
file in the
src
folder, which is the entry point for your app. It's responsible for rendering the main
App
component.
Another important file is the
package.json
. It contains information about your project, like its name, version, and dependencies.
What are dependencies?
Dependencies are external libraries and packages that your project relies on. You can install new ones using npm!
I see!
package.json
manages my project info and dependencies!
You got it! There are other files and folders as well, but these are the main ones you'll work with when developing a React app.
- Conclusion
The project structure of a React app includes the
publicfolder for static files, thesrcfolder for your React components and JavaScript code, and thepackage.jsonfile for project information and dependencies. By understanding the purpose of each file and folder, you’ll be better equipped to build your amazing React app! 🚀
