I am making an auction application that will run on iOS/Android and the also the web if logged in through a browser. The key feature here is that it will need to be pretty much real time, just like eBay.
I am having a difficult time coming up with a solution for which backend to use, I have used Django in the past along with the Django REST framework for serving mobile devices. For static images I used an S3 bucket to store and keep references to the images in the Django DB (mySQL).
Given that this auction app will need to be fairly real time, I was thinking of using Node, angular, mongodb and express (MEAN) along with featherless and socket.io for real time updates and REST queries.
Now, I wanted to know whether this is a good approach or not, is there a better way of setting up the backend by using something that I am not aware of?
I would like to keep all of the business side logic on the server, would Node be good for that? In Django, I was able to do quite a lot of server side logic in python which was a real plus, but I'm not sure if I can get the same flexibility with Node.
Some other options are firebase by Google, which are fairly real time, but I lack the knowledge to incorporate them into a web app.
I will be using AWS but I don't mind switching to another service if there is need.
Any tips are appreciated, thanks.
