Application Architecture Using CouchDB / PouchDB

I am wondering what the architecture should look like when used PouchDBas local storage in a mobile application instead localStorage.

At this point, I use to cache my application data in localStorage, and if necessary, I make an API call to the backend to request or send data. The backend adheres to all logic. For instance:

  • Does this user have the correct permission / role to perform this action?
  • Any other logic needed to verify whether an action can be performed.

All data is then stored in a relational database. Now I am reading about NoSQL databases and, in particular, CouchDBand PouchDB. So I wonder what this architecture looks like? At the moment, three questions arise for me:

  • If I have several users with their own authentication, how can I make sure that users only access their data? And will I still have 1 database on the server?
  • PouchDBon the client side can synchronize with the remote PouchDB. But when an application is created using Javascript, how do you make sure that people don’t paste data in PouchDBby “hacking” client-side Javascript?
  • Will there be a backend in such installations? And if you want to have an API for 3rd party, you just put, for example, a backend Sails.jsaround CouchDB?
