Create A React Project

We will now learn how to create a React project and host the repo in GitHub

Create React App

Create React App is a CLI tools that help you to create a project with all the required configurations for a typical React applications, e.g. webpack, Babel, and ESLint.

Create the Project

To create the project for our app, in your CLI, go to the directory that you want to create the project, and run the following command:

npx create-react-app react-movie-app
  • the command will create a folder react-movie-app and install all the required dependencies for your project. Have fun waiting :)
  • npx is a npm utility that allows you to run CLI tools conveniently. Without npx, you need to run 2 commands:
    npm install -g create-react-app
    create-react-app react-movie-app

After the command finish running, go into the folder and open it with VS code:

cd react-movie-app
code .

You should see the project structure as below:

Run the following command in the CLI, and your browser should open with the default Create React App application:

npm start

Host Your Repo in GitHub

Now that we've created the project, it's always good practice to host your repo somewhere instead of just on your PC, as you would never know when your PC will give you a surprise.

We will host our repo in GitHub.

  1. Create a new repo in GitHub (via this link or click the New button in your GitHub profile).

  2. Name the repo as "react-movie-app" (or something else if you wish). Click "Create Repository" button.

  3. Follow the "...push an existing repository from the command line" instruction on the page by running the command in your react-movie-app folder. It should be something like this:

    git remote add origin
    git push -u origin master
  4. Refresh the GitHub page. You should be able to see your code is available at the GitHub repo now.

Transferring Code to the Project

Now that we have a project, let's move our code to this project.

  1. Include our html code into public/index.html except the script tags.
  2. Replace the content of src/index.js with our code within the script tag. Remove all imports except React and ReactDOM imports. If you don't know what these imports statements are, no worries, I'll explain them shortly.
  3. Delete all the files in src folder except index.js file.

Now when you run npm start the application should be as per before.

Commit your code and push to your GitHub repo.

git add .
git commit -m "transfer code to project"
git push
