Overview
Adds support for the timers module to browserify.
Wait, isn't it already supported in the browser?
The public methods of the timers module are:
setTimeout(callback, delay, [arg], [...])clearTimeout(timeoutId)setInterval(callback, delay, [arg], [...])clearInterval(intervalId)
and indeed, browsers support these already.
So, why does this exist?
The timers module also includes some private methods used in other built-in
Node.js modules:
enroll(item, delay)unenroll(item)active(item)
These are used to efficiently support a large quantity of timers with the same timeouts by creating only a few timers under the covers.
Node.js also offers the immediate APIs, which aren't yet available cross-browser, so we polyfill those:
setImmediate(callback, [arg], [...])clearImmediate(immediateId)
I need lots of timers and want to use linked list timers as Node.js does.
Linked lists are efficient when you have thousands (millions?) of timers with the same delay. Take a look at timers-browserify-full in this case.
