I have a web application which currently uses postgres database. But I would like to make my application work in offline too. I found that CouchDB/PouchDB supports offline for web applications. But it says I have to use CouchDB in my existing backend instead of postgres. I would like to know is it possible to implement CouchDB in web app without changing the existing postgres database? Do I need to change the postgres database to couchDB to implement this feature? It is possible to do this - at least in theory. And I have certainly not done any work in this area yet so I cannot advise you on

With jQuery Mobile I can create a page using a custom theme <div data-role="page" data-theme="s" id="home">... Now this works, but requires that I add this line in each of my pages and every-time I add a new page. I tried adding data-theme="s" to the body tag but this has no affect. Is there any way to do this other then setting it manually per page? You would have to do it programmatically, AFAIK. Something along the lines of: $(document).bind( "mobileinit", function () { ... $.mobile.page.prototype.options.contentTheme = "z"; //your theme ... }); Now, since there is no centralized hook - you

Quick question for discussion really, as I wanted to have input from different people. I am in the process of developing a web page app that must be available offline. Now to do this, as I understand it, you would go about using either the application caching feature or by using service workers. However, here is the conundrum I have. When researching the application cache, the MDN clearly states : Deprecated: This feature has been removed from the Web standards. Though some browsers may still support it, it is in the process of being dropped. Do not use it in old or new projects. Pages or Web

I'm interested in building a small offline webapp and I'm looking for some advice. Here's the basics of what I want it to do Create reports that, initially, will just have a name and text field List, edit, and delete these notes Ideally I'd like to add more fields to the reports later Is localstorage a good option for storing this type of data locally? If so, can anybody direct me to a complete list of the commands for interacting with it in javascript? e.g. setItem, getItem, etc. Thanks. localstorage will work just fine for this, but don't think of it as a robust solution.. It's just a basic

I'm thinking of using firebase to write a mobile app using PhoneGap and the HTML5 Application Cache. Lets suppose each user has a list of TODO items. If the app is started when the phone is offline, will it be able to load data from the previous session and sync when a connection is established? If so I'm wondering how this is implemented because I couldn't find a reference to localStorage in firebase.js. Andrew Lee The short answer is: not yet. Once an app has connected to Firebase, the client will cache data locally and be able to access data where there is an outstanding "on" callback even
