callback to handle completion of pipe
Streams are EventEmitter
s so you can listen to certain events. As you said there is a finish
event for request (previously end
).
var stream = request(...).pipe(...);
stream.on('finish', function () { ... });
For more information about which events are available you can check the stream documentation page.
Code snippet for piping content from web via http(s) to filesystem. As @starbeamrainbowlabs noticed event finish
does job
var tmpFile = "/tmp/somefilename.doc";
var ws = fs.createWriteStream(tmpFile);
ws.on('finish', function() {
// pipe done here, do something with file
});
var client = url.slice(0, 5) === 'https' ? https : http;
client.get(url, function(response) {
return response.pipe(ws);
});
Based nodejs document, http://nodejs.org/api/stream.html#stream_event_finish,
it should handle writableStream's finish
event.
var writable = getWriteable();
var readable = getReadable();
readable.pipe(writable);
writable.on('finish', function(){ ... });
