event associated with fs.createWriteStream in node.js

node.js, stream

Solution

Updated 30 Oct 2013

Readable Steams emit `close` event when the underlying resource done writing.

r.on('close', function(){
  console.log('request finished downloading file');
});

But if you want to catch the moment when `fs` finished writing data to the disc, you need Writeable Stream `finish` event:

var w = fs.createWriteStream('/tmp/imageresize/'+x);

request(options1).pipe(w);

w.on('finish', function(){
  console.log('file downloaded to ', '/tmp/imageresize/'+x);
});

Problem

What event is triggered when EOF is reached while writing to a stream ? My code is as follows. and it is as per http://docs.nodejitsu.com/articles/advanced/streams/how-to-use-fs-create-write-stream But surprisingly my 'end' event is never fired. When I checked http://nodejs.org/api/stream.html#stream_event_end, I see that writable stream does not have any event on 'end' ``` var x = a1.jpg; var options1 = {'url': url_of_an_image, 'encoding': null}; var r = request(options1).pipe(fs.createWriteStream('/tmp/imageresize/'+x)); r.on('end', function(){ console.log('file downloaded to ', '/tmp/imageresize/'+x); } ``` How do I capture the EOF event ?
