The Choice of nodejs Picture Library

  node.js, question

Nodejs is required to operate the picture, mainly including:

Crop compression even obtains pixel values of all pixels of the picture, etc. …

If you look for it online, there are many, but I don’t know how to use it.

I don’t know if there is any better picture library.

Or is native writing better?

(expression ability is not very strong .. I hope experienced people can give me some advice

Gm has been used to upload pictures and generate thumbnails. You can refer to this library, but your server needs to be preinstalled with GraphicsMagick or ImageMagick.
