It's hard to have a one size fits all solution but often something light weight like sqlite on the device or client makes for ease of installation/config while scalability on the service side with something like sqlserver/mysql or couchdb/mongodb makes sense. The device and service storage options can be different (and likely should be) separate by service interfaces (soap, rest/http, sockets etc.). Also consider the service platform - for example, node goes well with mongodb (json objects front to back). On the service side, consider the nature of your data and whether it's fitted better for transactional/relational systems (banking etc.) or eventually consistent/non transactional (no-sql) documents. You also need to consider the type of clients - do you have many platforms varying from devices to PCs? You don't want something that has a heavy config and runtime footprint. Local storage options could be everything from something light like sqlite, sqlexpress, firebird to no sql options like mongo, couchdb etc.īut for the client or device, consider the ease of configuration and weight of the option. If you want clients that work seemless as they go offline and come online (like a POS with the power out) then I would recommend making the app primarily work off local storage with a background publishing or synchronization to the cloud. 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. though meteor does have mini mongo so it might be worth looking into. theres also all in one stacks like meteor and derby js, but those arent fully offline,but are for the appearance of real time. lets assume i need a client framrwork that can handle the data as well as the backend. ![]() 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. I would also like this to be offline for end users too, but the bigger audience is the admin.Īnother use case, instore POS system. but that could be messy.Īlso, 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. 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 what I am not sure of, is how to let the site function while offline. I realize for this to work I need to use a client side framework with my models/routes/controllers/whatever. 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. ![]() The app itself has an admin backend to manage that data and can change items. the db houses all the store's items and data. But, i have a site, sayĪnd on there is a couchdb instance, as well as a site to manage a store. 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. I have an app that I would like to create.
