Emotion vs React Flight: What are the differences?
Emotion: The Next Generation of CSS in JS. Emotion is a performant and flexible CSS-in-JS library. Building on many other CSS-in-JS libraries, it allows you to style apps quickly with string or object styles. It has predictable composition to avoid specificity issues with CSS. With source maps and labels, Emotion has a great developer experience and great performance with heavy caching in production; React Flight: The best way to build animation compositions for React. Flight tries to be for React what Principle is for Sketch compositions - the fastest, most friction free way to compose and an effortless way to animate an idea, an interaction, or a short movie-like composition in a self-contained widget (a React component after all).
Emotion and React Flight are both open source tools. Emotion with 8.39K GitHub stars and 524 forks on GitHub appears to be more popular than React Flight with 2.71K GitHub stars and 89 GitHub forks.
