Overview

Pug, ejs - those are example of template engines and the answer to Your question is: Yes, express supports it. What's more You can even create Your own template engine and use it in application what can bring a lot of fun (tutorial from official documentation: Developing template engines).

To use for example pug, You have to install it:

• npm install pug --save or yarn add pug

Tell express that You gonna use that specific one:

• app.set('view engine', 'pug')

Example

Lets assume that You have installed pug, express and You have that template in Your app:

html
  head
    title= title
  body
    h1= message

So to render it with custom title and message, go like that:

app.get('/hello-world', function (req, res) {
  res.render('index', { title: 'Hey', message: 'Hello there!' })
})

When someone will request '/hello-world' path with GET request, it will serve html template with:

• <title></title> in head element container -> Hey
• <h1></h1> in body element -> Hello there!.
