You can check that the install process ran correctly by typing pug -version into a terminal. Once Node and npm are installed on your system, you can install the pug-cli package like so: npm i -g pug-cli You can check out our tutorial вЂњ Installing Multiple Versions of Node.js Using nvmвЂќ for a more in-depth guide. It will also negate a bunch of potential permissions errors. I would recommend using a version manager where possible, as this will allow you to install different Node versions and switch between them at will. Either head on over to the projectвЂ™s home page and download the correct binaries for your system, or use a version manager such as nvm. ThereвЂ™s a couple options for installing Node/npm. Installing PugД«efore we can get to writing some Pug, weвЂ™ll need to install Node, npm (which comes bundled with Node) and the pug-cli package.

Otherwise, just be sure to add the word вЂњtemplateвЂќ to your Pug-related Google searches to avoid the results being full of pooches. If youвЂ™re interested in finding out more, you can read the original name change announcement in this GitHub issue. And while some of itвЂ™s probably still quite valid, the fact that the name change coincided with a major version bump means that PugвЂ™s syntax has several differences, deprecations, and removals compared to its predecessor.

ThereвЂ™s still a lot of Jade-related material available online. The name change took effect with version 2.0. ItвЂ™s also worth noting that Pug used to be called Jade until it was forced to change its name due to a trademark claim in 2015. This is illustrated by the following diagram. The template engine will normally receive data from an external source, which it will inject into the template itвЂ™s compiling. What Is Pug Used For?Д«efore we start looking at Pug, letвЂ™s take a second to understand the concepts involved.ДЄ template engine is a program which is responsible for compiling a template (that can be written using any one of a number of languages) into HTML. Finally, weвЂ™ll explore a couple of PugвЂ™s more advanced features by building a simple Node/Express project which uses Pug as its template engine. WeвЂ™ll start by installing it from npm, go over its basic syntax and then look at several examples of using JavaScript in Pug.

In this guide, IвЂ™ll demonstrate how to get up and running with Pug. Pug makes it easy both to write reusable HTML, as well as to render data pulled from a database or API. It compiles to HTML and has a simplified syntax, which can make you more productive and your code more readable. Pug is a template engine for Node and for the browser. This can be a nightmare to debug and to maintain. HTML is also static, which means that if you want to display dynamic data (fetched from an API, for example), you invariably end up with a mishmash of HTML stings inside JavaScript. This is where the Pug HTML preprocessor comes in. And while this is not the most difficult task, it can often feel a little boring or repetitive. As web designers or developers, we likely all have to write our fair share of HTML.
