Firefox3 to support cross-site sharing of js libraries?
Here’s some talk on this, over at the mozilla.dev.platform list.
I couldn’t resist blogging this… it’s an awesome tool!
Go checkout svn co http://svn.dojotoolkit.org/dojo/trunk/tools/jslinker, read
the instructions at http://svn.dojotoolkit.org/dojo/trunk/tools/jslinker/docs/readme.txt and … use it!
So, let’s say i create a web app that makes use of dojo and of tacos.
Currently, tacos.js is 54kb and dojo is at least 150kb. So, how about reducing this? How about keeping only the functions and the files that are actually called from the html files?
For my first example, i run
java -Xms8m -Xmx200m -cp jsl.jar:sisc.jar:bcel.jar org.dojo.jsl.top.Top –verbose –prj jsl.prj –sources ../tests/test_tacos.html
and was left with a 2.3kb dojo.js and a 6.3kb tacos.js
Doesn’t this rock??? Thx dojo & Well done to everyone involved.
This is a proposal for extending the script tag of HTML.
libraries that are now in common use (prototype, dojo, scriptaculous, e.t.c.) by many different sites
and minimize bandwidth – download times.
why do I have to redownload it while visiting site Z ?
So, I propose adding a hash attribute to the script tag. A browsers behaviour will go like this:
- if a script tag doesn’t have a hash attribute, continue as normal.
- If found, use library from cache.
- Otherwise, download library and use it. Also, compute its hash, and if it matches the hash attribute add
it in global cache.
So, what’s your opinion on this? Do you see any potential (security) problems?
