mp4 file upload issue in multer of node.js - node.js

Question

I'm trying to upload mp4 file by using multer in node.js
(View)VideoUploadPage.js
import React, { useState } from "react";
import Axios from "axios";
function VideoUploadPage() {
const onDrop = (files) => {
let formData = new FormData();
const config = {
header: { "content-type": "multipart/form-data" },
};
formData.append("file", files[0]);
console.log(files);
Axios.post("/api/video/uploadfiles", formData, config).then((response) => {
if (response.data.success) {
console.log(response.data);
} else {
alert("비디오 업로드를 실패 했습니다.");
}
});
};
}
(Server)
video.js
const express = require("express");
const router = express.Router();
const multer = require("multer");
const path = require("path");
const ffmpeg = require("fluent-ffmpeg");
let storage = multer.diskStorage({
destination: (req, file, cb) => {
cb(null, "uploads/");
},
filename: (req, file, cb) => {
cb(null, `${Date.now()}_${file.originalname}`);
},
fileFilter: (req, file, cb) => {
const ext = path.extname(file.originalname);
if (ext !== ".mp4") {
return cb(res.status(400).end("only mp4 is allowed"), false);
}
cb(null, true);
},
});
const upload = multer({ storage: storage }).single("file");
router.post("/uploadfiles", (req, res) => {
upload(req, res, (err) => {
if (err) {
return res.json({ success: false, err });
}
return res.json({
success: true,
url: res.req.file.path,
fileName: res.req.file.filename,
});
});
});
At the video.js destination: (req, file, cb) => {
cb(null, "uploads/")
} <----- I can check which file is going to upload with console.log(response.data), but there is no mp4 file in the "uploads" folder.
When I changed "uploads/" to my local directory path, mp4 file is on the uploads folder ....
ex: "C://~~~/uploads"
Any idea?

Answer 1

use path.resolve('./uploads') to resolve a sequence of path-segments to an absolute path.
let storage = multer.diskStorage({
destination: (req, file, cb) => {
cb(null, path.resolve('./uploads'); // path of the upload folder
},
filename: (req, file, cb) => {
cb(null, `${Date.now()}_${file.originalname}`);
},
fileFilter: (req, file, cb) => {
const ext = path.extname(file.originalname);
if (ext !== ".mp4") {
return cb(res.status(400).end("only mp4 is allowed"), false);
}
cb(null, true);
},
});

You can use path.resolve(process.cwd() + 'path till upload folder');
for eg:
path.resolve(process.cwd() + '/uploads');
