I'm new in using nodejs and multer and I want to upload an image but in two different directories. I tried using two different middleware but since the first multer function returns a file destination I couldnt use it to upload in the other multer function. Is it possbile to upload a file using multer in two different directories?

Create multiple storages and call them at the same time.
Example:
const app = require("express")();
const multer = require('multer');
const storageA = multer.diskStorage({
destination: function (req, file, cb) {
cb(null, './storageA/');
},
filename: function (req, file, cb) {
cb(null, file.originalname);
}
});
const storageB = multer.diskStorage({
destination: function (req, file, cb) {
cb(null, './storageB/');
},
filename: function (req, file, cb) {
cb(null, file.originalname);
}
});
const destA = multer({ storage: storageA });
const destB = multer({ storage: storageB });
function fileUpload(req, res, next) {
destA.single('file')(req, res, next);
destB.single('file')(req, res, next);
}
app.post("/", fileUpload, (req, res) => {
res.json({ file: req.file });
});
app.listen(3000, () => {
console.log("Server started");
});
The uploaded file will be store in ./storageA and ./storageB.
This is not an official way, but went I try it, it works!
