pouchdb

I have a single page web app written using AngularJS. It uses PouchDB to replicate to a CouchDB server and works fine. The problem comes when I try to convert the webpage to be available offline by adding cache.manifest. Suddenly ALL the replication tasks throw errors and stop working, whether working offline or online. In Chrome it just says "GET ...myCouchIP/myDB/?_nonce=CxVFIwnEJeGFcyoJ net::ERR_FAILED" In Firefox it also throws an error but mentions that the request is blocked - try enabling CORS. CORS is enabled on the remote CouchDB as per the instructions from PouchDB setup page. Plus

I am implementing an AngularJS web app with Firebase as a backend; it should work offline, too; multi-user sync issues should be very limited, since the app - by design - will only allow new data entries when offline. I understand Firebase has offline capabilities, in the sense that a client can withstand temporary network connection failures: any write operation will be delayed and cached until network comes up again. I ask if any possibility does exist (or does any plan to implement it) to extend Firebase offline capabilities to enable clients to locally cache a snapshot of (some of) the

I have been exploring using PouchDB as an offline cache for raster map tiles. Specifically, for Leaflet. I have just finished some preliminary tests which I thought I would share. Dr.YSG I have created a "JsFiddle" (actually I prefer CodePen these days), as a playground for showing how to use PouchDB to cache off-line raster map tiles. http://codepen.io/DrYSG/pen/hpqoD The Algorithm it uses is as follows: Test for presence of XHR2, IndexedDB, and Chrome (which does not have binary blobs, but Base64). and show this status info Fetch a JSON manifest of PNG tiles from GoogleDrive (I have 171 PNG

I'm currently in the process of writing an offline webapp using all the html5 goodies for offline support. However I'm starting now to think about writing the sync module that will ensure that any offline data gets sent to the server and server data back to the client. Now I'm sure this has been done before, I mean its a pretty classic design issue that affects mobile devices and a plethora of other things. So I'm wondering can anyone point me to some good design resources for this kind of thing? Now I really do not need to be too sophisticated with this, I mean I'm not handling multiple users
