Database Filler

Cordova app to fill up IndexedDB, based on Raymond Camden's blog: http://www.raymondcamden.com/2015/04/17/indexeddb-and-limits

Designed to figure out how much IndexedDB data iOS 8 will let you store in an app.

Note: you need to use the experimental WKWebView instead of UIWebView, because UIWebView doesn't support IndexedDB (see instructions below).

What the app does

Each time you hit "Add Data", it will insert a ~500KB image into the database, in base64 string format. So it's not exactly 500KB (in fact, it's probably quite a bit more due to the base64 overhead), but Apple's IndexedDB doesn't support Blobs, so it's what we have to do.

Install

Set up Cordova with WKWebView:

# if you don't have cordova
npm install -g cordova
npm install -g ios-sim

cordova platform add ios
cordova platform rm ios
cordova platform add ios@4.0.x --usegit
cordova plugin add https://github.com/apache/cordova-plugins.git#master:wkwebview-engine

Then run it:

cordova run ios

To run on a real device, you'll need to open up the XCode project under platforms/ios and then hit the "Run" button.

Details here: https://github.com/apache/cordova-plugins/tree/master/wkwebview-engine

Filling up lots of data

Just connect via Safari Web Inspector and run something like this:

setInterval(addData, 500);
