Why does Multer does not release memory?
I am developing node application to upload files, I can see that when multer receives a request with file 200KB for example, it then holds 400KB in the memory and does not release it even after the request finishes until the app receives a new request and do the same with the next request.
`const multer = require("multer"); const storage = multer.memoryStorage(); const upload = multer({ storage: storage });
const app = express(); const port = process.env.PORT || 3002;
app.use(express.json());
app.post("/submitRequest", upload.single("file"), async (req, res) => { return res.send('ok') });
const server = app.listen(port, () => {
console.log(Server is running on https://localhost:${port}
);
});
console.log('Server started at:', new Date().toLocaleString()); `
Not sure. My guess is it's loading the data in memory instead of streaming it. version 2.0.0-rc.4
introduces the stream
property so user land code can pipe it directly to a write stream for better memory performance.
