mongodb - MERN Stack, im getting a "parser is depreciated" and FAIL

Question

im getting a error that bodyParser is deprciated and also:

""" npm ERR! Failed at the [email protected] start script. npm ERR! This is probably not a problem with npm. There is likely additional logging output above. """

what causes it? i have my MongoDB Atlas setup, and information in the right place.

It means that using the bodyParser() constructor has been deprecated, as of 2014-06-19.

app.use(bodyParser()); //Now deprecated

You now need to call the methods separately

app.use(bodyParser.urlencoded());

app.use(bodyParser.json());

And so on.

If you're still getting a warning with urlencoded you need to use

app.use(bodyParser.urlencoded({
  extended: true
}));

The extended config object key now needs to be explicitly passed, since it now has no default value.

If you are using Express >= 4.16.0, body parser has been re-added under the methods express.json() and express.urlencoded().
