A lightweight only 1.8k (or 806 bytes gzipped) polyfill for addEventListener and removeEventListener, but also polyfills dispatchEvent and the DOMContentLoaded event, whilst supporting custom events.
It works passively, just include the script before anything that requires addEventListener and it will be available to use along with removeEventListener, DispatchEvent and the DOMContentloaded event.
The package is available from bower, npm or download the minified file and add it directly.
npm install addeventlistener-with-dispatch
bower install addeventlistener-with-dispatch
You can build from the source file(s) by cloning the repo and running the following npm commands from the command line
npm install
npm run build
Run the following command to launch a web browser. NB: As the code is aimed at polyfilling IE8 its advisable to run it against that.
npm test
Designed for use in IE8 as thats the newest IE available to Windows XP users, which there is still a large user base in some territories. IE9 and above all implement addEventListener correctly so does not replace the built in functionality.
