⚛️React setup : installing dependencies

installing the packages that React requires

Now, we can install three dependencies (for now) which allow us to use the React library and family of scripts:

npm install react react-dom react-scripts

Upon installation our package.json automatically updates to something like this:

// reactjon/package.json

{
  "name": "reactjon",
  "version": "1.0.0",
  "description": "",
  "main": "src/index.js",
  "scripts": {
    "start": "react-scripts start",
    "build": "react-scripts build",
    "test": "react-scripts test --env=jsdom",
    "eject": "react-scripts eject"
  },
  "browserslist": [
    ">0.2%",
    "not dead",
    "not ie <= 11",
    "not op_mini all"
  ],
  "keywords": [],
  "author": "",
  "license": "ISC",
  /* this got updated */
  "dependencies": {
    "react": "^18.2.0",
    "react-dom": "^18.2.0",
    "react-scripts": "^5.0.1"
  }
}

(The dependencies property adds in react + react-dom + react-scripts !)
