These pre-processors are like besties with popular web frameworks too.

If you're a React head, Create React App's got your back with built-in Sass support. For the Angular fam, just run ng add @angular-devkit/schematics-cli --name=[your-project-name] && ng generate @schematics/angular:universal --client-project=[your-project-name] to unlock Sass.

And Vue CLI supports multiple pre-processors right outta the box in its single file components.

Tryna learn how to configure Sass/LESS/Stylus in your web projects? Just peep some tutorials that break down the vital steps – installing pre-processor npm packages, setting up build scripts with tools like Laravel Mix or webpack.mix.js, and firing up those watch tasks for real-time compilation so you can code without interruptions.

Facing challenges and finding solutions when using CSS pre-processors with UI libraries is like a whole 'nother level.

You might run into compatibility issues or need to maintain source maps for debugging. Around 30% of devs deal with compilation errors, according to the surveys.

But don't sweat it – just make sure your configs are on point and your library versions jive with the pre-processor's version. Once you clear those initial setup hurdles, you'll be styling like a boss with less redundancy, tapping into the true power of pre-processors that industry forums can't stop raving about.
