Node.js: image resizing without ImageMagick

I would vote for sharp:

sharp('input.jpg')
  .resize(200, 200)
  .toFile('ouput.jpg', function(err) {
    // output.jpg is a 200 pixels wide and 200 pixels high image
    // containing a scaled and cropped version of input.jpg
  });

It’s fast, typically 6x faster than the fastest imagemagick-based node bindings, and runs in very little memory, perhaps 10x less. sharp links to the libvips image library directly, there is no shelling out to an external program, and the library itself is faster and more efficient than *magick at this task. It supports useful things like stream, buffer and filesystem input and output, colour management, transparency, promises, overlays, WebP, SVG, and more.

As of sharp 0.20, npm will automatically download complete pre-compiled binaries on most platforms, so there’s no need for node-gyp. Just enter:

npm install sharp

or:

yarn add sharp

And off you go.
