npm express "hello world" middleware error

Question

node --version v0.10.26

npm --version 1.4.3

I followed this: http://expressjs.com/guide.html

which has this code

    var express = require('express'),
    app = express();
app.use(express.logger());

app.get('/', function(req, res){
    res.send('Hello World');
});

var server = app.listen(3000, function() {
    console.log('Listening on port %d', server.address().port);
});

I try 'node app.js' in the terminal and I got this error:

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

I'm new with express, any help will be welcomed. Thanks.

Solution 1

I faced the same problem. I ran the below from the directory where my node js file was

npm install --save morgan

Using above command adds the dependency to your package.json.

Once package added, logger can now be used as

logger = require('morgan');
app.use(logger('dev'));

Solution 2

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

express.logger('dev') is removed from express module.

use logger like morgan.

var morgan = require("morgan");
app.use(morgan('combined'));

for more details on morgan checkout the below link morgan

Solution 3

You need a previous version:

npm install [email protected]

Should be app.use there instead of app.user.
