Express is a small framework that sits on top of Node.js web server functionality to simplify its APIs and add helpful new features. It makes it easier to organize your application’s functionality with middleware and routing; it adds helpful utilities to Node.js’s HTTP objects; it facilitates the rendering of dynamic HTTP objects. 

In this article, we are going to learn how to use the pug engine in Express.js.

Let us first start by creating a node.js project named pug. For that let’s create the folder named pug and run the command npm init in it.

 

Now that we have set up our project, let’s now install the necessary packages.

First, we install Express.js, to install we will run the command:

npm install express --save

 

Next, we will install pug. Run the following command to install:

npm install pug --save

 

Now to set pug as the view engine, run the command:

express --pug 

or 

express --view=pug

 

Now run the project by using the command:

npm start
