What is a bundle size?

To understand what a bundle size means, we have to understand what bundling is.

Bundling is the process of a bundler(like webpack, parcel, or snowpack) to combine different groups of assets such as HTML, CSS, JavaScript, and images to produce a smaller file known as a bundle. Bundling is necessary to reduce the number of HTTP requests the browser has to make to serve content to users.

Bundle size is the size of any generated bundle and it affects how long it takes for our websites and web apps to load.

In this article, we’ll be exploring how to reduce our Tailwind CSS powered app bundle size by tree-shaking Tailwind CSS, we will also learn how to use PurgeCSS with Tailwind in production, we will explore how to do that in JavaScript frameworks such as Vue and React.

What is Tailwind CSS?

It’s a utility-first CSS library used to build custom designs, it offers no pre-configured styles and components to build with, rather it offers you a set of unopinionated building blocks known as utility/helper classes to help you style your components.

According to its official documentation:

Tailwind CSS is a highly customizable, low-level CSS framework that gives you all of the building blocks you need to build bespoke designs without any annoying opinionated styles you have to fight to override.

What is PurgeCSS?

PurgeCSS is a development workflow tool for removing unused CSS in a project, it is the default library for controlling Tailwind CSS bundle sizes. It tree-shakes unused styles and optimizes CSS build sizes.

According to its official documentation:

PurgeCSS analyzes your content and your CSS files. Then it matches the selectors used in your files with the one in your content files. It removes unused selectors from your CSS, resulting in smaller CSS files.
