How do I get data from neDB database and compare this data with AngularJS?

I'm working on a web application to learn NodeJS and AngularJS but i'm having some troubles. This applicatio consists in : - database (with neDB) which contains users - nodejs (with express) to wrap all the thing up - angularjs for the web layer

I don't see how to get data in the database (I think we have to parse in JSON what the database contains) and compare it with what the user of the application will put in the form in order to connect himself.
