Assuming the name of your file in your HTML file is image, req.files.image.data.length will give you the buffer length in bytes. See this Node.js. API Documentation for more details. You can then do the math to convert the number of bytes into any thing you want.

This will allow you to get the actual number of bytes independent of filetype and doesn't require using the mv function. So you can use this on any file type not just images.

Hopefully this helps!

I think only way to get image info using express-fileupload is using mv function to move image on server then using image-size to get width and height
