Sass vs styled-components: What are the differences?

Key Differences between Sass and styled-components

Sass and styled-components are two popular options for styling in web development. However, they have some key differences that make them unique. Here are six key differences between Sass and styled-components:

  1. Syntax: Sass uses its own syntax, which is an extension of CSS with additional features, such as variables, nesting, and mixins. On the other hand, styled-components uses a CSS-in-JS approach, where you write actual CSS code within JavaScript using tagged template literals.

  2. Scoping: In Sass, styles are scoped within the same file where they are defined through nesting. This allows for modular and reusable styles. Styled-components, on the other hand, scopes styles at the component level, ensuring that styles are encapsulated and only apply to the specific component they are defined for.

  3. Dependencies: Sass is a preprocessor that requires a build step to compile Sass code into regular CSS. This means that you need to set up a build process and potentially install additional dependencies. On the contrary, styled-components does not have any build dependencies and can be used directly in the browser without any additional setup.

  4. Dynamic Styling: Sass allows for dynamic styling using variables and mixins, but the dynamic nature is limited to the preprocessor level and requires recompilation to reflect changes. In contrast, styled-components allows for dynamic styling directly within the component's JavaScript code, making it more flexible and powerful.

  5. Component-Based Styling: Styled-components promotes a component-based approach to styling, where each component is responsible for its own styling. This leads to more modular and reusable code. On the other hand, Sass does not have native support for component-based styling, and the responsibility of styling is typically shared between different Sass files.

  6. Tooling Ecosystem: Sass has a mature and extensive tooling ecosystem with a wide range of third-party libraries and frameworks available. This includes build tools, IDE integrations, and code editors with specific support for Sass. In comparison, styled-components, being a relatively newer approach, has a smaller tooling ecosystem but is still actively growing.

In summary, Sass is a popular choice for its powerful preprocessing capabilities and extensive tooling ecosystem, while styled-components offers a modern CSS-in-JS solution that provides component-based styling, scoping, and dynamic styling within JavaScript. The choice between them depends on the specific requirements and preferences of the project.

StylusStylus

Originally, I was going to start using Sass with Parcel, but then I learned about Stylus, which looked interesting because it can get the property values of something directly instead of through variables, and PostCSS, which looked interesting because you can customize your Pre/Post-processing. Which tool would you recommend?

You're not correct with saying "vs Postcss". You're using Less/Sass/Stylus/... to produce "CSS" (maybe extended means it has some future features) and then in any case PostCSS will play (it is shipped with Parcel/NextJS/CRA/...)
