Error while running app.js

[Mehul Bhatt]

I am new to nodejs+express stack. Trying to learn it using your project as a templated. I see following error despite installting connect package seperately. Can you please guide where is the issue.

C:\Users\m\Desktop\node\angular-express-seed-master>node app.js
body-parser deprecated bodyParser: use individual json/urlencoded middlewares ap
p.js:28:9

Error: Most middleware (like errorHandler) is no longer bundled with Express and
must be installed separately. Please see https://github.com/senchalabs/connect#
middleware.

In your app.js file on line 36, there should be a reference to body-parser, change that to body-parser.json. If that doesn't work, please paste the code in app.js here. Good luck

[Mehul Bhatt]

There is just 1 reference to body parser with require() function. The change did not work. Here is the app.js pulled from Git.
/*

• Module dependencies
  */

var express = require('express'),
bodyParser = require('body-parser'),
methodOverride = require('method-override'),
errorHandler = require('error-handler'),
morgan = require('morgan'),
routes = require('./routes'),
api = require('./routes/api'),
http = require('http'),
path = require('path');

var app = module.exports = express();

/**

• Configuration
  */

// all environments
app.set('port', process.env.PORT || 3000);
app.set('views', __dirname + '/views');
app.set('view engine', 'jade');
app.use(morgan('dev'));
app.use(bodyParser());
app.use(methodOverride());
app.use(express.static(path.join(__dirname, 'public')));

var env = process.env.NODE_ENV || 'development';

// development only
if (env === 'development') {
app.use(express.errorHandler());
}

// production only
if (env === 'production') {
// TODO
}

/**

• Routes
  */

// serve index and view partials
app.get('/', routes.index);
app.get('/partials/:name', routes.partials);

// JSON API
app.get('/api/name', api.name);

// redirect all others to the index (HTML5 history)
app.get('*', routes.index);

/**

• Start Server
  */

http.createServer(app).listen(app.get('port'), function () {
console.log('Express server listening on port ' + app.get('port'));
});

Read the first line of your error: line 28.

Change it to:
app.use(bodyParser.json());

Note - it still doesnt work after this change but now its on to the next bug with errorHandler...

[Justin Ireland]

Ok, I think I figured out the remaining issues...

run: npm install express-error-handler
change line 9 to: errorHandler = require('express-error-handler'),
change line 36 to: app.use(errorHandler());

The app should run now.
