There's a library called filepreview that:

Will generate a file preview (gif, jpg or png) of about 450 different document formats.

That includes PDF. It seems quite heavy-weight (because of all the formats it supports), but looks like it will do exactly what is required:

var filepreview = require('filepreview');

filepreview.generate('test.pdf', 'test_preview.png', function(error) {
  if (error) {
    return console.log(error);
  }
  console.log('File preview is test_preview.png');
});
