title: Offline apps with Node.JS and CouchDB
body: <p>I have an app that I would like to create. But I am not sure how to go about it. I am using node.js and would like to use couchdb, but if something like mongodb or riak would be a better choice them im willing to hear ideas. But, i have a site, say</p>
  
  <p>cool.com</p>
  
  <p>and on there is a couchdb instance, as well as a site to manage a store. say a shopping cart. the db houses all the store's items and data. The app itself has an admin backend to manage that data and can change items. What  i would like to be able to do, is have the ability to have the user be disconnected from the internet, and still have the admin backend work. I realize for this to work I need to use a client side framework with my models/routes/controllers/whatever. But what I am not sure of, is how to let the site function while offline. couchdb if installed locally can sync the data from local to remote when back online, and if the admin user is on the computer, i could have them install couch. but that could be messy.</p>
  
  <p>Also, what if the admin user is on a tablet or a phone? Would I need to have an actual mobile app and a desktop app to do this? is there some way I can set this up so it is seamless the the end user. I would also like this to be offline for end users too, but the bigger audience is the admin.</p>
  
  <p>Another use case, instore POS system. and the power goes out. But the POS system can be loaded from the web onto a tablet and they can still make card based sales if the wifi is out, because the app is available offline.</p>
  
  <p>Im just not sure how to do this. lets assume i need a client framrwork that can handle the data as well as the backend. something like ember, or angular. theres also all in one stacks like meteor and derby js, but those arent fully offline,but are for the appearance of real time. though meteor does have mini mongo so it might be worth looking into.</p>
  
  <p>I was hoping someone could help me figure out how I would get this setup to work, preferrably with couch, but other nosql's would work too if I can have a way to sync the data.</p>
