Question

Node.js

I can’t do anything ((I upload via postman form/data, connection-muptiparty is connected, output req.files is empty(((
+ I make a request via postman: form-data, I specify the key (file) in the body and the file type is file, select image 100kb, press send
how to get image properties ?
console.log(req.files.file); TypeError
: Cannot read property 'file' of undefined
get its properties..
res.json({par: req.body});
