I want to upload file with multer and sharp;but resize not work with toBuffer.

here is my codes:

sharp(req.file.path)
                 .resize(20,20).toFormat('jpeg')
                 .toBuffer(function (err,info) {
})

But if i use with toFile works perfectly.like this:

 sharp(req.file.path)
                     .resize(20,20)
                     .toFile("ss.jpg",function (err,info) {
    })

isn't the toBuffer receives a callback with `(err, data, info)` ? – Aritra Chakraborty Aug 01 '18 at 13:15

The purpose of a buffer edit the image more without using disks, it will be stored in memory so chaining edits will be faster. But if that is accomplished then you actually need to write the buffer to file or show it in browser converting it to a base64. check this answer to do it. https://stackoverflow.com/questions/38503181/how-to-display-a-jpg-image-from-a-node-js-buffer-uint8array – Aritra Chakraborty Aug 01 '18 at 13:35
