Configuration file

You can configure the file upload in Nomran/server/config.json. You can add the section fileUpload

The following are the options that can be passed to File Upload.

• dest
• limits
• includeEmptyFields
• inMemory
• mimetype
• scanAction

dest

The destination directory for the uploaded files.

dest: './uploads/'

limits

An object specifying the size limits of the following optional properties. This object is passed to busboy directly, and the details of properties can be found on busboy's page

• fieldNameSize - integer - Max field name size (Default: 100 bytes)
• fieldSize - integer - Max field value size (Default: 1MB)
• fields - integer - Max number of non-file fields (Default: 50)
• fileSize - integer - For multipart forms, the max file size (in bytes) (Default: 25Mo)
• files - integer - For multipart forms, the max number of file fields (Default: 10)
• parts - integer - For multipart forms, the max number of parts (fields + files) (Default: 10)
• headerPairs - integer - For multipart forms, the max number of header key=>value pairs to parse Default: 2000 (same as node's http).

limits: {
  fieldNameSize: 100,
  files: 2,
  fields: 5
}

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

includeEmptyFields

A Boolean value to specify whether empty submitted values should be processed and applied to req.body; defaults to false;

includeEmptyFields: true

inMemory

If this Boolean value is true, the file.buffer property holds the data in-memory that Multer would have written to disk. The dest option is still populated and the path property contains the proposed path to save the file. Defaults to false.

inMemory: true

WARNING: Uploading very large files, or relatively small files in large numbers very quickly, can cause your application to run out of memory when inMemory is set to true.

mimetype
