Next with NX using tailwind takes over 20 min to compile

Link to the code that reproduces this issue

https://github.com/nolafs/Rocket-house-productions/tree/development

To Reproduce

1. I first notice it after I merged my feature into development branch but it must have been there before because both branches require 20 min + to compile
2. I only added additional components into my library
3. I did not change or alter the default setup by NX for Next with tailwind

Current vs. Expected behavior

It is taking around 22 min to compile the project. When removing Tailwind imports such as base, compile time is normal. Removing NX createGlobPatternsForDependencies(__dirname) and importing each library manually seems to fix it as well.

    "/Users/olafsiebert/html/rocket_house_productions/libs/shared/ui/src/**/*!(*.stories|*.spec).{tsx,ts,jsx,js,html}",
    "/Users/olafsiebert/html/rocket_house_productions/libs/shared/layout/src/**/*!(*.stories|*.spec).{tsx,ts,jsx,js,html}"
   // ...createGlobPatternsForDependencies(__dirname),

Here is the output of createGlobPatternsForDependencies

Additional context

I am running the lastest versions

I found the solution. I am using Prismic in my project. Prismic does not support monorepos. To make the Slice Machine work, I had to install it inside the application, which creates a node_modules folder. The createGlobPatternsForDependencies helper does not exclude the nested node_modules folder, and Tailwind will process this folder. This is the cause of the 20-minute build time. I came up with a simple hack.

const content = [...createGlobPatternsForDependencies(__dirname)];
const index = content.findIndex((item) => item.includes('apps/kids-guitar-dojo'));
content[index] = content[index].replace('apps/kids-guitar-dojo/', 'apps/kids-guitar-dojo/(!node_modules)');
