Uploading Files with Multer

Multer is a middleware for handling file uploads in Express.

Snippet:

const multer = require("multer"); const upload = multer({ dest: "uploads/" }); app.post("/upload", upload.single("file"), (req, res) => res.send("File uploaded"));

Example:

const upload = multer({ storage: multer.memoryStorage() }); app.post("/upload", upload.array("files", 5), (req, res) => res.send("Files uploaded"));
