Properties never on req.body, so not parsed

[knownasilya]

According to this if the value is on req.body, then it gets parsed.

I do a formdata post, and the fieldname is exercise[muscles] which is an array, but it's not on req.body (it's {})... So it never gets passed as an array, but a comma separated string..

Multer only parses multipart/form-data, are you sure that your data isn't arriving as urlencoded since there isn't any files attached?

You could try to add the following code to see the content-type that is sent to the server.

app.use(function (req, res, next) {
  console.log(req.get('Content-Type'))
  next()
})

Feel free to reopen if you find more info :)
