How could I upload files in ExpressJS 4.x

Question

I know there are something like multiparty, and busboy and formidable. I want to know is there any chance to upload files without them.

Answer 1

Without them, parsing multipart forms can be hard to do right and efficiently. Unless you really want to go through that work of parsing multipart yourself (urlencoded forms are much easier), you really should stick to using one of connect-multiparty, multer, connect-busboy, reformed, etc.
