delta-file-multer/uploader.js

A simple plug-n-play file upload middleware using Multer and MongoDB

import multer from "multer";
import { ensureDirExists } from "./utils/ensureDir.js";

export const setupUploader = ({ uploadPath }) => {
  ensureDirExists(uploadPath);

  const storage = multer.diskStorage({
    destination: function (req, file, cb) {
      cb(null, uploadPath);
    },
    filename: function (req, file, cb) {
      const timestamp = Date.now();
      const uniqueName = `${timestamp}_${file.originalname}`;
      cb(null, uniqueName);
    },
  });

  return multer({ storage });
};
