This is a common issue that comes up for SPA. In SPA, mostly the routing happens on client side. In your case, mostly react-router should be doing the job. Since the whole js is bundled as a single file and is served in index.html, you need to serve index.html for all paths that is non-existing in your server.

You have to add a config like this

RewriteEngine On  
RewriteCond %{DOCUMENT_ROOT}%{REQUEST_URI} -f [OR]
RewriteCond %{DOCUMENT_ROOT}%{REQUEST_URI} -d
RewriteRule ^ - [L]

RewriteRule ^ /index.html [L]

So, if there is no matching path in your server, the index.html would get served. Then the javascript would execute and react-router(client side routing) will take over and display the correct component for the route.

This is true for most SPA, where the routing happens on client side.
