How do CSS Modules affect web performance?

How do CSS Modules affect web performance?

CSS Modules can improve performance by scoping styles locally, reducing the risk of style conflicts and unnecessary CSS bloat.

Can you explain how they help with caching?

Sure! CSS Modules generate unique class names, which can help with caching since styles are less likely to change, allowing browsers to cache them effectively.

What about the initial load time?

Initially, CSS Modules might increase load time slightly due to the additional processing, but they often lead to smaller, more efficient stylesheets overall.

Are there any downsides to using CSS Modules?

One downside is the learning curve; developers need to understand the module system. Additionally, it may complicate global styles.

How do they compare to traditional CSS in terms of performance?

CSS Modules generally offer better performance in larger applications by reducing style conflicts and improving maintainability, but traditional CSS can be simpler for small projects.
