Previously I used React/Redux/Saga just as "presentation" layer of an application with Ruby/Rails and Nodejs back-end.
Currently there are couple of back-end services (which I don't control) I should use for authentication and fetching data in my React/Redux/Saga application.
On my local machine I can run my React/Redux app with help of webpack-dev-server, so it could receive requests from browser.
But what about production environment? Is it possible to deploy React/Redux/Saga application without Nginx, Nodejs, Rails?
For sure. It depends on what are you going to use for deployment. F.e. in our projects, we use
IIS server for this. It would be published as a simple web app with configurated fallback settings.
