limits

An object specifying the size limits of the following optional properties. Multer passes this object into busboy directly, and the details of the properties can be found on busboy’s page.

The following integer values are available:

Key Description Default
fieldNameSize Max field name size 100 bytes
fieldSize Max field value size 1MB
fields Max number of non-file fields Infinity
fileSize For multipart forms, the max file size (in bytes) Infinity
files For multipart forms, the max number of file fields Infinity
parts For multipart forms, the max number of parts (fields + files) Infinity
headerPairs For multipart forms, the max number of header key=>value pairs to parse 2000

Specifying the limits can help protect your site against denial of service (DoS) attacks.
