npm --version 1.4.3

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

which has this code

Answer 1

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

Answer 2

The first line tells it all:

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

Looking at https://github.com/senchalabs/connect#middleware we can see that express.logger has been replaced with morgan.

var logger = require('morgan');
app.use(logger); //replaces your app.use(express.logger());

Remember to npm install morgan and/or add it to your package.json

Answer 3

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'));

Answer 4

You need a previous version:

npm install express@3.0.0
