pug

HTML Generation

Pug allows you to write simplified syntax that compiles into HTML. The above code will generate a standard HTML5 document structure with a title and a heading.

doctype html
html(lang='en')
  head
    title My Site
  body
    h1 Welcome to My Site

Dynamic Content

You can use variables in Pug to dynamically insert content into your templates. The above code will output an h1 tag with the user's name.

- var user = { name: 'John Doe' }
h1= user.name

Conditionals

Pug supports conditional statements, allowing you to render different parts of your template based on certain conditions. In this example, the h1 tag will only be rendered if the user is logged in.

- var user = { loggedIn: true }
if user.loggedIn
  h1 Welcome back!

Loops

Pug provides a way to iterate over arrays and objects with loops. This code will produce an unordered list with each fruit as a list item.

- var items = ['Apple', 'Banana', 'Cherry']
ul
  each item in items
    li= item

Mixins

Mixins in Pug are reusable blocks of Pug that can be included anywhere in your templates. The above mixin creates a hyperlink, and it is used to add a link to Google.

mixin link(href, name)
  a(href=href)= name
+link('http://google.com', 'Google')

Includes and Extends

Pug allows you to include content from other Pug files and extend templates to create a base template (layout) that can be shared across multiple pages. The 'index.pug' extends 'layout.pug' and provides content for the title and body blocks.

// layout.pug
doctype html
html
  head
    block title
  body
    block content

// index.pug
extends layout.pug

block title
  title My Page

block content
  h1 My Page Content
