Appending one more chunk to the end of a stream.

[Scott Corgan]

Been sitting on this one for awhile and can't seem to figure it out or find anyone that has a solution.

I just need to append one more chunk to the end of a stream. At first, I thought I was successful using the "through" module, but for some reason, it kept appending the new chunk in the middle of the stream.

Any direction would be helpful, thanks.

Couldn't you override the end() method to push your last chunk, then call the original end?

premature send...

//assume var originalOutputStream

var originalEnd = originalOutputStream.end

originalOutputStream.end = function(data) {

  originalOutputStream.write(data);

  originalOutputStream.write(finalData);

  originalEnd.call(originalOutputStream);

}

That looks like it would work. Tried it, and I'm getting my chunk put into the middle of stream, instead of the end. I'm using the "node-trumpet" module to parse html.

I filed an issue for the module, so I'm not sure if it's the module or my code.

mySource.pipe(myDestination, {end: false});

mySource.on('end', myDestination.write.bind(myDestination, myChunkIdLikeToAppend));

or

var StreamStream = require('stream-stream');

var chunkStream = new require('stream').PassThrough();

var ss = new StreamStream();

ss.write(mySource);

ss.write(chunkStream);

ss.pipe(myDestination);

chunkStream.end(myChunkIdLikeToAppend);

[Floby]

Sorry, the second line should look like

mySource.on('end', myDestination.end.bind(myDestination, myChunkIdLikeToAppend));
