Compare FAQ

Which has more lines of code, styled-components/styled-components or emotion-js/emotion?

styled-components/styled-components has more code: 118,177 code lines versus 15,963 for emotion-js/emotion, about 7.4x as much, based on cached OctoCounts reports as of 2026-08-26.

Does more source lines of code mean more complexity?

Not necessarily. SLOC measures size, not complexity, quality, or maintainability. A larger codebase can mean more features, more generated or vendored code, more verbose language idioms, or more tests — none of which imply the code is harder to work with. Use SLOC to gauge the scale of what you'd be reading or maintaining, not as a quality signal for styled-components/styled-components, emotion-js/emotion, or any repository.
