If you want to build a complete web application with React from scratch, you have to fulfill the following points :
* Your code has to be bundled using a bundler like webpack and transformed using a compiler like Babel.
* You have to do production optimizations such as code splitting.
* You have to pre-render some pages for performance and SEO statically. You might also want to use server-side rendering or client-side rendering.
* You might have to write some server-side code to connect your React app to your data store.
