I have a React + Webpack/Babel + Node/Express application and I want to deploy it on AWS.
Would I have to deploy React and Node/Express separately? Or could they be deployed together at once?
e.g. a React single-page app and a Node/Express API.
the frontend (the React app) on S3 and CloudFront (tutorial)
the backend (the Node API) on Elastic Beanstalk (recommended) or EC2
Another option is to deploy both parts together at once on Elastic Beanstalk or EC2. However, you'll miss out on the benefits of hosting on S3 and CloudFront, i.e. faster delivery for your users and cheaper costs. In my opinion, it's also more convenient and less prone to unexpected errors to update and deploy separately the client-side and the server-side of a web application.
Another benefit of deploying separately: For organizations with different teams for the frontend and backend, it's easier for each team to be able to deploy their side of the application on their own without depending on the other team.

redirectionYou can use different subdomains, e.g.
api.domain.com
for the Node/Express APIapp.domain.com
for the React appThen enable CORS in the API:
app.get('/api', cors({ origin: 'https://app.domain.com' }), ...)
e.g. a Node app including some React views.
You have to deploy the whole app on Elastic Beanstalk or EC2.
Note: If you have a single project including two sub-projects (i.e. a folder for the React app and another one for the Node API), and if both sub-projects still work when they are separated, then you can deploy the sub-projects separately (see first part of the answer).
Run your Webpack build before deploying the React part. You can do it manually (before deploying on AWS) or automatically (in your CI/CD system). If you bootstrapped your app with create-react-app (CRA), just run yarn build
or npm run build
at the root of the project and upload the content of the "build" folder to your S3 bucket.
