Multer

A Node.js middleware for handling multipart/form-data, primarily for file uploads. Built on top of busboy for maximum efficiency. Current stable version is 2.0.1 (released 2024, maintenance mode with only critical updates). Key differentiators: simple API for single/multiple file uploads, integrates directly with Express, supports disk and memory storage. Not suitable for non-multipart forms. Release cadence: irregular, few updates since 2021. Competes with formidable and express-fileupload.
