Does installing npm react react-dom in create react app is necessary?

I read the documentation of reactstrap, and it guide us to install npm package as below;

npm install --save bootstrap
npm install --save reactstrap react react-dom

my question is, is it necessary to install react and react-dom, aren't those two packages are included by default in create-react-app?

Solution

  • Yes! it is included in node_modules by default when you use

    npx create-react-app app-name

    but you may also choose not to use it for some reason. Then you will need to install them and add your project starting files by yourself.
