This command formats the whole buffer (default), the visual selection or an arbitrary range, using js-beautify (https://www.npmjs.org/package/js-beautify).
It is generic enough to be adapted to other languages easily.
Place the snippet in
command! -buffer -range=% Format let b:winview = winsaveview() | \ execute <line1> . "," . <line2> . "!js-beautify -f - -j -B -s " . &shiftwidth | \ call winrestview(b:winview)
