Express Web Application Development

Empowering Express with middlewares

In Chapter 1, What is Express?, we learned about Express middlewares and saw how to create one. Now, let's go find out how to include one in our app. Remember we use app.use() for including middlewares.

Though we can write our own middlewares, we will focus on using one of the middlewares that comes bundled with Express.

For your reference, the following is the list of the middlewares that are available in Express, by default:

Middleware	Description
router	The app's routing system
logger	Log requests to the server
compress	gzip/deflate support on the server
basicAuth	Basic HTTP authentication
json	Parse application/ json
urlencoded	Parse application/x-www-form-urlencoded
multipart ...
