Configuring ReactJS On MacOS

Prerequisites

The React docs recommend using npm to create a new React app.

npm requires Node >= 6.

To install npm and node:

1. Install XCode from the Apple App Store.
2. Install homebrew:

   ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

3. Use homebrew to install node:

   brew install node

4. Confirm that node is installed:

   node -v

5. Confirm that npm is installed:

   npm -v

Creating a new React app

Use npm to install the utility that creates new React app boilerplate (this only needs to be done once):

$ npm install -g create-react-app

Use create-react-app to create a new app:

$ create-react-app my-app

Start the app:

$ cd my-app
$ npm start

After running the app with npm start the app will be available at http://localhost:3000
