Node: How to wait until a file is completed before processing it?

Question

My Problem is that I can not be sure when a file has been successfully written to and the file has been closed. Consider the following case:

var fs = require(\'f         


        

Answer 1

Do your file's post-processing in the writeable stream's close event:

outs.on('close', function() {
  <<spawn your process>>
});

Also, no need for the destroySoon after the end, they are one and the same.

Answer 2

Check out https://github.com/TomFrost/FlushWritable – I don't know why it's not written into the Writable core but this should do the trick.

Also, there's a discussion addressing this on GitHub https://github.com/nodejs/node-v0.x-archive/issues/7348.
