Question

Automate the process of making Tailwind Classes non-Global with ease!

I am currently working on an application that consists of two main parts:

(X) an older AngularJs legacy application with its own set of CSS classes.
(Y) a new React application contained within a div. This new part (Y) is built using webpack, postcss, and TailwindCSS.

My main concern is ensuring that the TailwindCSS classes used in part Y do not clash with the stylesheets of part X, and vice versa, without making significant changes to the existing codebase.

Challenges to Overcome

Although I have explored some possible solutions, most of them seem to involve drastic modifications:

One option involves utilizing the TailwindCSS prefix configuration, but I am hesitant to prefix a large number of classes due to the length of the prefix itself.
Another approach is to use css-modules with local imports. However, I am uncertain about how well this method integrates with TailwindCSS, and I find the process of locally importing classes from various sources to be verbose and cumbersome.

Possible Solutions

While I have come across a couple of postcss plugins that seem promising, they have their limitations:

postcss-rename is effective, but it does not address the renaming of classes within *.js files.
purgecss can identify classes based on their presence in *.js files and remove them from the output list, but it lacks the ability to rename classes.

One feature that appears to be missing in existing solutions is the parser for *.js files within purgecss.

An Ongoing Challenge

Is there a way to automatically apply a custom transformation (e.g., renaming) to all postcss classes, including those used in HTML/JSX elements? Alternatively, is there a method for webpack to automatically resolve CSS class conflicts?

One way to enhance Tailwind's functionality is by utilizing the prefix options.

With the prefix option, you have the ability to seamlessly integrate a custom prefix to all of Tailwind's utility classes. This feature proves to be particularly handy when incorporating Tailwind into existing CSS codebases where naming conflicts may arise.

For instance, you can designate a tw- prefix by adjusting the prefix option as demonstrated below:

// tailwind.config.js

module.exports = {
  prefix: 'tw-',
}

Consider using a hyphen to shorten class names and improve aesthetics

module.export = {
  prefix: "-"
}

It can make a project look more visually appealing

You no longer need to manually add prefixes to your source code when using the tailwind prefix feature.

To start, make adjustments to tailwind's class extractor:

const { defaultExtractor: createDefaultExtractor } = require('tailwindcss/lib/lib/defaultExtractor')
const { default: resolveConfig } = require('tailwindcss/lib/util/resolveConfig')

const defaultExtractor = createDefaultExtractor({
  tailwindConfig: resolveConfig([{ content: [''] }])
})

const extractor = (content) => {
  return defaultExtractor(content).map((cls) => 'tw-' + cls)
}

/** @type {import('tailwindcss').Config} */
module.exports = {
  content: {
    extract: {
      ts: extractor,
      tsx: extractor
    }
  }
}

Utilize react-beyond, a library for higher-order components that automatically add prefixes to all classnames within the entire react tree (not restricted to a specific component). You can refer to the source code in the gallery for examples: (Please note: this is my personal library.)
