I have subclassed a transform stream. As part of the constructor function I
set up an interval. I need to make sure I clear this interval when the
stream is done, so I don't have a memory leak. Where is the best place to
do this?
I am considering using the end-of-stream module to detect when the stream
instance is finished to trigger the clearTimeout. Is there any edge case I
would miss by doing this?
var eos = require('end-of-stream');
function SomeTransformStream() {
Transform.call(this);
var self = this;
// on constructor, setup timeout
this._timeoutId = setTimeout(function () {
self.doSomething(); // some code I need called
});
// on end of stream destroy self
eos(this, function() {
// is this thorough enough?
clearTimeout(_self.timeoutId);
});
// ... some more stuff
}
Thanks in advance.
