In plain words
Multer handles file uploads on the server — product photos, article images, documents. Each upload is inspected before it is accepted: its real type, its size, and where it is allowed to go.
Multer
How files reach your system safely: every upload is checked for what it really is and how large it is, then stored where it can never be run.
What it does for you
File upload is one of the classic ways a website is broken into: a program renamed to look like an image, uploaded, then opened by the server. Here the type is verified, the name is rewritten, and nothing uploaded can ever be executed.
Your team sees a simple drag-and-drop; the risk is handled behind it.
What it gives your system
- File type and size verified before anything is stored
- Uploaded files can never be executed
- File names rewritten, so nothing can be overwritten
- Clear limits, with a readable message when a file is refused
