Using HTTP basicAuth, bodyParser, cookieParser and other modules in ExpressJS 4.0

ExpressJS 4.0 removes all middlewares and make them independent packages. Therefore we cannot use ExpressJS 3.0 code directly. For basicAuth, some people implement their own version of HTTP basic authentication. But I think the easiest way is to use npm to install "basic-auth-connect" module:

var basicAuth = require('basic-auth-connect');
app.use(basicAuth('username', 'password'));

Follow the same rule, just install the necessary modules then we can use the old 3.0 codes! But the names of the new modules are different from original ones. The complete mapping table is as below (thanks to  Chris Sevilleja):

Express 3.0 Name	Express 4.0 Name
bodyParser	body-parser
compress	compression
cookieSession	cookie-session
logger	morgan
cookieParser	cookie-parser
session	express-session
favicon	static-favicon
response-time	response-time
error-handler	errorhandler
method-override	method-override
timeout	connect-timeout
vhost	vhost
csrf	csurf
