Minifying js/css content in-memory?

Hello - I'm curious why there isn't a method for this that doesn't involve having content in files? I have a use-case where I have a JS snippet loaded in memory (variable), and I'd like to produce a minified version without first writing it to a file, then reading from output file, then worrying about that clean-up on top of that. I thought, maybe it's trivial for you to implement.

Thanks.

It's live in 5.1.0
You can use it like that:

const html = `
<!doctype html>
<html>
    <head>
        <meta charset="utf-8">
    </head>
</html>
`;

minify({
  compressor: htmlMinifier,
  content: html,
  options: {
    minifyJS: false
  },
  callback: function(err, min) {
    console.log('callback min');
    console.log(min);
  }
}).then(function(min) {
  console.log('html min');
  console.log(min);
});

You need to pass the compressor according the content (html, css, javascript).
I will see if I can find a solution to detect content type and use defaults compressors.

You can also still pass options to the compressor.
