This is potentially an issue for two reasons:

It will download the latest version of create-react-app, as well as react, react-dom, react-scripts, and other packages. However, there's one important thing to know about npx. In the case of create-react-app, npx will first ask permission to download the package, to which you should enter 'y'. So, there's no need to download a package before directing Node to use it. Because we want to execute the create-react-app package, npx is the right command here.Īnother nice thing about the npx command is that it can automatically execute packages that haven't been installed yet, by going and fetching the information on the npm registry.

The npm command is used for managing packages while the npx command actually executes those packages. npx is automatically bundled with recent versions of npm. Note that we are using the npx command, not the npm command. We can create our first create-react-app with the following command: npx create-react-app help-queue While more complex applications may need custom configurations, create-react-app will cover all our needs and allow us to focus on learning React, not get bogged down in configuring our environment. However, keep in mind that we won't be able to customize our configuration without ejecting our application, a process we will cover in just a moment. This will make developing applications with React much more convenient.

create-react-app uses tools like webpack behind the scenes but we will not need to customize our environment ourselves.Ĭreate-react-app comes with a default configuration right out of the box. While this is a valid approach to building React applications, we've had plenty of practice with webpack, Node packages, and Babel during the Intermediate JavaScript course.įortunately, we can use create-react-app, a tool that will set up our project for us.

This involves creating custom webpack configurations, adding Node packages, and customizing Babel to fit the needs of the project. Some developers build React applications from scratch.
