Hey Greelgorke,
You're missing the point. I'm suggesting that `npm link` shouldn't do
the global thing by default.
Also, if people use package mangers node will end up in /usr/, not
/usr/local.

NB: this has nothing to do with the way node or npm is installed,
while it is true that node end up in /usr, package managers have npm
configured to global-install modules to /usr/local by default.

Is it correct to assume that a Readable won't emit the readable event
until you're registered for it?
Reading through the streams2 docs, I was under the impression that all
streams start out paused and don't start emitting data until you add either
a data (for old streams) or a readable listener.
readable is emitted after you've actually started reading.
In your example, you dont ever `response.read()`, so no readable event
is ever emitted.
As you said, streams start in paused state and ready to be read.

That's not what it says in the

.

When there is data ready to be consumed, this event will fire.
When this event emits, call the read() method to consume
You can always call `stream.read`, at any time. This is how data is
*pulled*off the stream (instead of it being pushed to you, whether
you're ready or
not). Because of this you won't lose any data. With new streams there's no
real notion of a paused state -- it's always paused. Once you grok that
You're right, my bad.
But still, data stay in the buffer until someone tries to `.read()`.
So, if you're being passed a stream that you dont know whether the
first `readable` event has fired, you can try to actually read from
it. If it returns null, then you wait for `readable`.
On 03/25/13
You *must* try to read from it. Otherwise it's likely to remain paused.

If stream.read returns null that could mean one of two things:
1) the stream doesn't currently have any data, but still might have some

2) the stream is already ended
AFAICT, the only way you can know which state you're in is by checking the
stream.readable property which is
You're absolutely right. I totally forgot about that aspect of the

Yeah, I think the old streams still had lots of confusion around them and
the adoption wasn't great. If we can't beat that with streams2 then we are
doing a lot of work for not much gain. I think there are common themes that
barrier to understanding with both approaches. I've been trying to think

Ok, that makes sense.
So the readable event is more of an advisory event. The docs should
probably say something about how you could possibly miss the event entirely
if you're doing some other IO before you try and read from the stream.
For posterity's sake, I adjusted my previous example:
That's not guaranteed to work.
You're assuming that `stream.read()` will return the whole internal
buffer, which is not documented anywhere.
The right approach is to call `.read()` until it returns null.
Something like that:
function collectStream(stream, cb) {
var bufs = []
function
I can see what you're saying, but the node docs do
sayhttp://nodejs.org/api/stream.html#stream_readable_read_size_1that
if you don't pass a size argument to stream.read then the entire
contents of the internal buffer are returned.
In any case, this would all be a lot easier if the readable event

A small amendment to #3: if read returns null it could also mean that the
stream is ended. So you need to register for the end event as well. It
looks like streams internals refuse to fire end until at least one call
to stream.read has happened, so you're guaranteed to get that event.
