Uploadig multiple files with different requirements in multer

• multer

  20 11,321 4.7 JavaScript

  Node.js middleware for handling `multipart/form-data`.

  

  Multer's file filter is a function with req, file and cb as args. Now file has mimetype property. So hence you can make a custom fileFilter function which would impose different size restrictions. For different storage options/location maybe you can find a workaround or you can make a custom storage engine. Heres a reference https://github.com/expressjs/multer/blob/master/StorageEngine.md

  A streaming parser for HTML form data for node.js

  I checked out StorageEngine and apparently , it will fix the problem with memory storage for thumbnail. But I also checked out Busboy which Multer is based on. and it looks like the File size limit functionality comes from Busboy. Like, multer get fileSize and passes it to Busboy and then busboy handles limiting the incoming data for all files. So I guess it is not possible to set multiple limit size from multer. Thanks
