Pug is a template engine that allows you to write cleaner templates with less repetition. In Angular, you can use Pug to write component templates and improve a project’s development workflow. In this article, Zara Cooper explains what Pug is and how you can use it in your Angular app.

As a developer, I appreciate how Angular apps are structured and the many options the Angular CLI makes available to configure them. Components provide an amazing means to structure views, facilitate code reusability, interpolation, data binding, and other business logic for views.

Angular CLI supports multiple built-in CSS preprocessor options for component styling like Sass/SCSS, LESS, and Stylus. However, when it comes to templates, only two options are available: HTML and SVG. This is in spite of many more efficient options such as Pug, Slim, HAML among others being in existence.

In this article, I’ll cover how you — as an Angular developer — can use Pug to write better templates more efficiently. You’ll learn how to install Pug in your Angular apps and transition existing apps that use HTML to use Pug.

Pug (formerly known as Jade) is a template engine. This means it’s a tool that generates documents from templates that integrate some specified data. In this case, Pug is used to write templates that are compiled into functions that take in data and render HTML documents.

In addition to providing a more streamlined way to write templates, it offers a number of valuable features that go beyond just template writing like mixins that facilitate code reusability, enable embedding of JavaScript code, provide iterators, conditionals, and so on.

Although HTML is universally used by many and works adequately in templates, it is not DRY and can get pretty difficult to read, write, and maintain especially with larger component templates. That’s where Pug comes in. With Pug, your templates become simpler to write and read and you can extend the functionality of your template as an added bonus. In the rest of this article, I’ll walk you through how to use Pug in your Angular component templates.
