Hello everybody,

I am new to ionic and want to convert a native Android project to ionic.  
My application receives and sends data from/to some kind of web service (I am flexible and can change it), however, it should be available even if the client is offline. So I really need a two-way offline/online sync function.

Any ideas how to solve this smart in ionic?

Thanks,

David

Read Azure Mobile services. Are there some other solution free and not. If I try info, I’ll write here.

thank you!  
I am now trying to implement it using pouchDB. It seems to address exactly my issues.

Hi p6n!

I’m planning a similar app for one of my customers.

Did PouchDb manage the offline synch of files, images, etc… well?

Would you suggest me to use it?

Yes, PouchDB [does support attachments](https://pouchdb.com/guides/attachments.html), just like CouchDB.
