Zero transpiles and bundles all the code files (
.md, etc). But otherwise it just serves the file as-is.
Your static files (images, documents, etc) can reside alongside your code files. It won't affect your code.
If you project is structured like this:
- project/ - index.jsx - style.css - logo.png
If you visit
http://localhost:3000/ it will render your React page. The logo file is accessible at
http://localhost:3000/logo.png as you would expect.
