CSS Modules vs SCSS: Which Should I Use?

What are the main differences between CSS Modules and SCSS?

CSS Modules are a way to scope CSS by default, preventing class name collisions, while SCSS is a preprocessor that adds features like variables and nesting to CSS.

When should I use CSS Modules instead of SCSS?

Use CSS Modules when you need modularity and scoped styles, especially in large applications. SCSS is great for complex styles and theming.

Can I use both CSS Modules and SCSS together?

Yes, you can use both together! You can write SCSS in your CSS Modules to take advantage of both scoped styles and SCSS features.

What are the performance implications of using one over the other?

CSS Modules can lead to smaller CSS files due to scoping, while SCSS may generate larger files if not managed properly. However, the difference is often negligible in modern applications.
