Data Storage
Remy Sharp
dATA SToRAgE IS
fundamental in nearly all applications,
web or desktop. This can include storing a unique key to
track page impressions, saving usernames and prefer-
ences, and so on. The list is endless.
Up until now, storing data in a web app required you to
either store it on the server side and create some linking
key between the client and the server—which means your
data is split between locations—or store it in cookies on
the client.
Cookies suck. Not the edible ones, the ones in the
browser. They're rubbish. There's a number of issues with
cookies that make them a pain to work with. On starting
any new project that requires cookies, I'll immediately go
hunting for my cookie JavaScript library. If I can't find that,
I'll head over to Peter-Paul Koch's cookie code, and copy
and paste away.
