Q:

Can a React App run on AWS S3

I am creating a React App that doesn't have a database connection for the moment, am just trying to get the frontend UI working before I get the database up.  I have been trying to host the application on AWS S3 as a static website but not having much luck.  I have linked up the React CDN to an index.html page but when I run it nothing seems to be rendering. 
Question is, is it even possible to have a React App running on S3?  Or do I need to have a Node server running? 

A:

Yes, hosting a react app on S3 is possible.  All you need to do is create a build of your project and upload those files on s3 as a static website.  
The build just creates a bundle of all your js files and dependency which can just be hosted.  I found a great detailed article on how you can setup s3 and build and deploy your react app.
