I was recently testing some stream piping like
rstream
.pipe(foo)
.pipe(bar)
.on('error', function (err) {
// handle the error
});
and I found out that currently stream.pipe does not forward
the 'error' events, so if you wanted to handle the
errors you would need to do something like
rstream
.on('error', handleError)
.pipe(foo)
.on('error', handleError)
.pipe(bar)
.on('error', handleError);
or possibly rely on domains to deal with the error, but
I would prefer to leave domains for other more
catastrophic errors and just deal with errors at the
end of the pipe chain.
The current node.js code checks to see if the source has any error
listeners and if there are none then it throws an Error. If there was an
error listener on the source then it will be given the error to deal with.
So to all the experienced streams users out there,
1. How do you believe it should work? (or is there a better way)
2. Is there any edge cases that we need to consider if we were to implement
as I described above?
Thanks in advance for your input!
Jeff
