How to paste text on an image with a background in the middle and multiline?

Question

JavaScript

I just need to sculpt text on images where there should be a black background. I decided to paste the text on the newly created object, get the size of the output result in pixels, add a background and merge it with the image itself. This is how shit turned out in the end:

gm(400, 100, 'black')
      .font("Helvetica.ttf", 50)
      .fill('#333')
      .drawText(0, 0, 'hello world how are you me interesting ???', 'Center')
      .write('new.jpg', (err) => {
        if (err) console.log(err);
        gm('new.jpg').size(function(err, size) {
          console.log('size: ', size);
                      // .drawRectangle(coords, size)
        });
      });

and the problem - I get the size given initially, which I do not need, I need a dependent size resulting from the size of the text.
Please help, mb there are other modules for this work
