Multer is Node.js middleware for handling multipart/form-data, primarily used for file uploads, built on top of busboy. It integrates with Express and adds body and file/files objects to the request.
Use cases
- handle file uploads in express
- parse multipart form data in node.js
- upload images from html form to server
- accept multiple file uploads with size limits
- process form fields and files together in a post request
When to choose
- you need to accept file uploads in an Express or Node.js HTTP server
- your forms use multipart/form-data encoding
- you want a lightweight, battle-tested middleware built on busboy
When to avoid
- your forms are not multipart (e.g. JSON APIs)
- you need direct browser-side file handling
- you want a full-featured upload service with resumable uploads
