Introduction to React
Node.js and npm
npm is a repository of Node.js packages and also a command-line utility for accessing and managing those packages. Using npm we can easily initiate a new Node.js project and import any desired project from the library of available projects.
To use Node.js:
- Install it from the official website(npm included);
- Open the command prompt and type in
node --versionto check if node is correctly installed (if Node's version is displayed, everything installed correctly);
There are some useful commands:
- Initiating a new node:
- Installing new packages:
npm install <package name>;
- Running a node script:
node <script name>.
With the help of Node we can set up a React project and test it conveniently using a package called
create-react-app provided by Facebook, that includes all the required tools. We will explore more about it in a later section.
