Angular 2 Data Saving

Our development team began a great transition to the Angular2 / Ionic2 infrastructure, and one small detail left us puzzled - what is the best way to achieve data continuity? I found an almost two-year-old Google Doc in design to save Ang2 data, however it doesn't seem to be implemented at all. I need the most important functions:

  • client-server data binding, so every change is automatically committed
  • local dataset for working with the application offline
  • offline operation caching, synchronization with the server immediately upon reconnection

(In short, the functionality of Swarm.js, for example) I searched for blogs, stackoverflow, but haven’t answered anything yet - as far as I understand, I can’t even use widespread external solutions like PouchDB to solve this problem, and constantly do HTTP receiving / post calls with manual caching in localStorage will not do this for the projects we are working on. What do you think? Is there any way to achieve this?

PouchDB dev is here. Basically, you can use any client database with Angular. Personally, I wrote several Angular applications that used direct PouchDB (I never saw the need for angular-pouchdb TBH). Here is an open source example: https://github.com/pouchdb/npm-browser

PouchDB is optimized for synchronization with CouchDB. If you just want the simple Key Storage API to be replaced by LocalStorage, I would recommend LocalForage . It is based on a promise, so you can just wrap it with $q.when() and use it in an Angular service, and it should feel pretty native to Angular.
