How to copy a file?

Question

How to copy a file in Node.js?

Example

+ /old
|- image.png
+ /new

I want to copy image1.png from \'old\' to \'new\' directory.

Answer 1

newFile.once('open', function(fd){
    require('util').pump(oldFile, newFile);
});     

Answer 2

The preferred way currently:

oldFile.pipe(newFile);

Answer 3

fs.rename( './old/image1.png', './new/image2.png', function(err){
  if(err) console.log(err);
  console.log("moved");
});

Answer 4

If you want to do this job syncronously, just read and then write the file directly:

var copyFileSync = function(srcFile, destFile, encoding) {
  var content = fs.readFileSync(srcFile, encoding);
  fs.writeFileSync(destFile, content, encoding);
}

Of course, error handling and stuff is always a good idea!
