how to store image from buffer to file system in node.js using sharp.js

i am using sharp.js for image manipulation in node.js

my code 

sharp(path)
        .toFormat('jpeg')
        .toBuffer((err, data, info) => {
            fs.writeFile(temp, buffer, { flag: 'w' }, function() {
                response.sendFile(temp);
            });
        });

here temp in fs means "the path" var temp= imageDir + request.params.id; ( http://localhost:2000/images/we.png )

  1. upload image as png format or any other format

  2. convert that image to JPEG using .toFormat('jpeg') and send to buffer

  3. want to save that image from buffer to

You can do this

sharp(req.files[0].path).resize(400, 200).toFile('uploads/' + 'thumbnail-' + req.files[0].originalname, (err, sharp) => {
            if (err) {
                console.error(err);
            }
            else {
                console.log(sharp);
            }
        });

Your code doesn't have 'buffer'. You should be writing data.

.toBuffer((err, data, info) => {
        fs.writeFile(temp, data, { flag: 'w' }, function() {
            response.sendFile(temp);
        });
    });

but you'd be better off using toFile instead of toBuffer:

sharp('originalFile.jpg').
        resize(330,null).
        flatten().
        toFile('newFile.jpg', function(err){
            if(err){
                response.sendStatus(500);
                return;
            }
            response.sendFile('newFile.jpg');
        });
