问题:

I have angular2 & mongoDB configured. So far I am able to read json files using http service but I want to develop a complete application which will have database connectivity too.

So i would like to know how can I configure my angular2 app so that it can interact with the database.

Any inputs?

Thanks in advance.

You should utilise a framework such as ExpressJS to handle the interaction with the database which returns JSON data in the same way as you are currently doing with a static file.

There are quite a few tutorials around which explain how to do this such as http://adrianmejia.com/blog/2014/10/01/creating-a-restful-api-tutorial-with-nodejs-and-mongodb/

The other option you have is to use a framework to do much of the heavy lifting around building the API. Loopback is a good start for such a task as they have a generator which can generate client side code to interact with your API making the implementation much easier than building everything yourself. I haven't used it in a while so I'm not sure if they have ng2 as a client side generator yet, but it might be a good place to start.
