Node.js File Upload: Handling Large Files with Streams

[Techi11]

I'm building a Node.js application that allows users to upload large files, potentially several gigabytes in size. I want to handle these uploads efficiently to minimize memory usage and provide a smooth user experience.

Currently, I'm using a basic approach like this:

const express = require('express');
const multer = require('multer');
const upload = multer({ dest: 'uploads/' });

const app = express();

app.post('/upload', upload.single('file'), (req, res) => {
    // Process the uploaded file here
    const file = req.file;
    console.log(file);
    res.send('File uploaded successfully');
});

app.listen(3000, () => {
    console.log('Server started on http://localhost:3000');
});

This code works for small files, but I'm concerned about the performance and memory usage when dealing with large files. What are the recommended practices for a Node.js application's handling of massive file uploads? I visited a few sites in an effort to locate the answer, but I did not receive a good response. How can I effectively handle and store these files using streams or other methods without using a lot of memory? It would be extremely appreciated if there were any code snippets or libraries that might assist with this particular use case. I appreciate your knowledge.
