4 Replies to "Styled-components vs. Emotion for handling CSS"
Interesting read 🙂
I did the same comparison a month ago. I built two simple blog applications with a dark theme. One with Emotion and one with Styled Components. I used the object syntax for styling my React components
Styled components and Emotion looked equal in any way. All I had to do was change the imports.
Regarding performance and bundle size; there was barely any noticeable difference. The Emotion.js proof of concept was like 2kb smaller.
Since I was already using Emotion.js for my React projects I chose to stick with it.
Your styled-component examples import from ‘@emotion/styled’ which is misleading, but also highlights the fact that the API for these 2 libraries is nearly identical. It would have been helpful to have a technical breakdown comparing performance, bundle sizes, and limitations of each library.
The styled-components examples have the wrong imports in the code blocks. You should correct these for clarity.
Thanks Kasra for comparing them and thanks Peter for sharing your results too.
Based on that, I would choose Styled Components because of the community, at least on GitHub, the numbers are double compared to Emotion.
