In case you need a quick laugh, read all the comments of people not looking at the dependencies they include at https://github.com/dominictarr/event-stream/issues/116
If you add an external dependency to your code, you add external code to your application. If you're using outdated or unmaintained dependencies, don't complain to the author - remove the dependency or fix it.
Anyway, people need to calm down in github issue discussions.
