Prerequisites

1. The app that uses tailwind + external component library (CL) (but not 3rdparty, your company internal one, for example)
2. The component library also uses tailwind

The goal

To be able to purge safely unused tailwind classes from the build (https://tailwindcss.com/docs/controlling-file-size)

Solution

The idea here is simple: we're going to purge css on the app side + whitelist classes that component library is using.

What forces layout / reflow

All of the below properties or methods, when requested/called in JavaScript, will trigger the browser to synchronously calculate the style and layout*. This is also called reflow or layout thrashing, and is common performance bottleneck.

Generally, all APIs that synchronously provide layout metrics will trigger forced reflow / layout. Read on for additional cases and details.

Element APIs

Getting box metrics

• elem.offsetLeft, elem.offsetTop, elem.offsetWidth, elem.offsetHeight, elem.offsetParent
