So now we have the base file and the folder structure sorted. The next step is to start scaffolding our app using the Bootstrap CSS.

I'm sure you have a question: what is scaffolding? Simply, it gives a support structure to make your base concrete.

Apart from this, we will use React-Bootstrap JS in which we have a collection of Bootstrap components rebuilt for React. We can use these throughout our Employee Information System (EIS). Bootstrap also includes an extremely powerful responsive grid system which helps us to create a responsive theme layout/template/structure for the app.
