Does anyone know of any Node.js framework that will allow me to host different mobile backend with a single node.js and mongodb?
Full disclaimer, I am new to Node.js.
Strongloop Loopback. It's built on top of Node.js , express.js & swagger. Almost all basic features such as data paging, ACL, Authentication ( email , social login) , model persistence, and more , are already in there, ready to use & extend them as you wish (y)
From experience you must check Deployd. Its super easy nodejs package for building REST API's with nodejs and mongodb. You will get built-in users system api and regular crud api in 5 minutes with nice GUI.

If you are building API driven apps with Node.js then it'll be easy to reuse these in mobile. Basically you will create APIs that will be consumed by both web and mobile apps. This way you don't have to write separate backend code for building mobile apps. Now that you are using Node.js you can use a minimalistic framework like Express to build your APIs. Take a look at this discussion.
Let me know if you need more help.
