I have a collection of functions similar to this here: https://github.com/dominictarr/event-stream
you need to add `destroy`, and should add `pause` and `resume`. this may be helpful: https://gist.github.com/2850882 it's my best effort at defining the correct behaviour for streams, such that pipe will work correctly. it's not official of course, its just constructed from reading node/lib/stream.js and so on, and figuring it out. cheers, Dominic On Sat, Jun 23, 2012 at 10:23 PM, dolphin 278 <[email protected]> wrote: > Good day > > I did not found any modules to easily wrap any function to stream interface, > so i made my own.
