As the subtitle suggests, this script brings the power of events from platforms such as node.js to your browser. Although it can be used on any other platform, I just built it with browsers in mind.
This is actually the fourth full rewrite of EventEmitter, my aim is for it to be faster and lighter than ever before. It also has a remapped API which just makes a lot more sense. Because the methods now have more descriptive names it is friendlier to extension into other classes. You will be able to distinguish event method from your own methods.
Building the documentation
npm install dox dustjs-linkedin
Or by running
tools/deps.sh to fetch all dependencies required by the repository.
Then you can run
tools/doc.sh to build from the JSDoc comments found within the source code. The built documentation will be placed in
docs/api.md. I actually keep this inside the repository so each version will have it's documentation stored with it.
You can grab minified versions of EventEmitter from the downloads page. If you need to build a custom version then you will first need to install the uglifyjs node module (
npm install uglify-js) and then you can run
tools/dist.sh. You can also fetch the dependencies by running
tools/deps.sh. The script takes one optional argument which specifies the version that should be placed in the minified files name,
4.0.0 for example. If not passed then it defaults to
So with a version passed you will get a file name like
dist/EventEmitter-4.0.0.min.js, without one you will be left with this
You can clone the repository with your generic clone commands as a standalone repository or submodule.
# Full repository git clone git://github.com/Wolfy87/EventEmitter.git # Or submodule git submodule add git://github.com/Wolfy87/EventEmitter.git assets/js/EventEmitter
If you wish to run the tests you will also need to fetch the required submodules. You can do that with the following command.
git submodule update --init
Alternatively you can execute
tools/deps.sh to fetch all required dependencies for the repository.
If you only need the script itself you may want to look at the downloads page.
You can also get a copy of EventEmitter through the Bower package manager. Simply run
bower install eventEmitter.
Tests are performed using Jasmine in the following browsers via BrowserStack.
When testing in the more modern browsers, not Internet Explorer basically, I run it through the very early versions, some midrange versions and the very latest ones too. I don't just do the latest version.
EventEmitter will always be tested and working perfectly in all of them before a release. I will not release anything I think is riddled with bugs. However, if you do spot one, please submit it as an issue and I will get right on it.
