Recently, I decided to clean-up some of the code in MobileFrontend related to localStorage. The other mobile devs suggested that I implement a generalized solution that could be upstreamed to core. I looked at some 3rd party jQuery plug-ins and decided to implement a solution based on jQuery Store. I stripped out all the extraneous crap and added support for cookies (since localStorage quotas are often rather small for mobile devices) and caching. The end result can be seen at:
https://gerrit.wikimedia.org/r/#/c/131239/After I checked this in, I was informed that there is already a client-side storage plug-in in core: jStorage, as well as another one being used by Flow, Storer. Both of these seem a bit like overkill to me and I would prefer to implement something simple and light-weight for mobile. Also jStorage doesn't support fall-back to cookies.
What are people's opinions on moving forward on this? Should mobile have it's own lightweight plug-in, should we modify jStorage in core so that it meets our requirements, or should we adopt Storer and push for it to replace jStorage in core?
