bodyParser is deprecated express 4

Question

I am using express 4.0 and I'm aware that body parser has been taken out of the express core, I am using the recommended replacement, however I am getting

body-parser deprecated bodyParser: use individual json/urlencoded middlewares server.js:15:12 body-parser deprecated urlencoded: explicitly specify "extended: true" for extended parsing node_modules/body-parser/index.js:74:29

Where do I find this supposed middlewares? or should I not be getting this error?

var express     = require('express'); var server      = express(); var bodyParser  = require('body-parser'); var mongoose    = require('mongoose'); var passport    = require('./config/passport'); var routes      = require('./routes');  mongoose.connect('mongodb://localhost/myapp', function(err) {     if(err) throw err; });  server.set('view engine', 'jade'); server.set('views', __dirname + '/views');  server.use(bodyParser());  server.use(passport.initialize());  // Application Level Routes routes(server, passport);  server.use(express.static(__dirname + '/public'));  server.listen(3000); 

Answer 1

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().
