# Overview
|
| 2 |
|
|
|
| 3 |
|
|
Adds support for the `timers` module to browserify.
|
| 4 |
|
|
|
| 5 |
|
|
## Wait, isn't it already supported in the browser?
|
| 6 |
|
|
|

|
The public methods of the `timers` module are:
|
| 8 |
|
|
|
| 9 |
|
|
* `setTimeout(callback, delay, [arg], [...])`
|
| 10 |
|
|
* `clearTimeout(timeoutId)`
|
| 11 |
|
|
* `setInterval(callback, delay, [arg], [...])`
|
| 12 |
|
|
* `clearInterval(intervalId)`
|
| 13 |
|
|
|
| 14 |
|
|
and indeed, browsers support these already.
|
| 15 |
|
|
|
| 16 |
|
|
## So, why does this exist?
|
| 17 |
|
|
|
| 18 |
|
|
The `timers` module also includes some private methods used in other built-in
|
| 19 |
|
|
Node.js modules:
|
| 20 |
|
|
|
| 21 |
|
|
* `enroll(item, delay)`
|
| 22 |
|
|
* `unenroll(item)`
|
| 23 |
|
|
* `active(item)`
|
| 24 |
|
|
|
| 25 |
|
|
These are used to efficiently support a large quantity of timers with the same
|
| 26 |
|
|
timeouts by creating only a few timers under the covers.
|
| 27 |
|
|
|
| 28 |
|
|
Node.js also offers the `immediate` APIs, which aren't yet available cross-browser, so we polyfill those:
|
| 29 |
|
|
|
| 30 |
|
|
* `setImmediate(callback, [arg], [...])`
|
| 31 |
|
|
* `clearImmediate(immediateId)`
|
| 32 |
|
|
|
| 33 |
|
|
## I need lots of timers and want to use linked list timers as Node.js does.
|
| 34 |
|
|
|
| 35 |
|
|
Linked lists are efficient when you have thousands (millions?) of timers with the same delay.
|
| 36 |
|
|
Take a look at [timers-browserify-full](https://www.npmjs.com/package/timers-browserify-full) in this case.
