A:
Use Multer’s diskStorage option:
const storage = multer.diskStorage({
destination: (req, file, cb) => {
cb(null, ‘uploads/’); // local folder
},
filename: (req, file, cb) => {
const unique = Date.now() + ‘-‘ + file.originalname;
cb(null, unique);
}
});
const upload = multer({ storage });
Then apply the upload middleware to your route. After a successful upload, you can (in the route handler) respond with file paths or metadata to the client.
