Hello.

During our Google IO talk on Mobile Web Development, we received a great question about handling AppCache storage limits in modern browsers. Our approach was straightforward: we primarily used AppCache for program code, including CSS and JS, along with the main page. Our application's size remained manageable, helped by minifying the JS in our production build using uglifyJS. Although we could have compressed the CSS, we prioritized ease of development. If space became an issue, our plan was to AppCache only form-factor specific code and assets, but thankfully, that wasn't necessary.

During my "Mobile Web Development: From Zero to Hero" talk at Google I/O, a question came up about client-side data storage now that WebSQL is deprecated. While IndexedDB is on the horizon, what are developers using today? I shared my preference for Lawnchair, a simple key-value store abstraction that's easy to use and perfect for many situations. While I didn't use it in the IO Reader app due to late-stage project constraints and the sufficiency of localStorage, I generally prefer using such libraries. I'm interested in hearing from others. What data storage wrappers or techniques do you prefer when building web apps?
