    Our take

    Understanding Emotion.

    Emotion is a performant CSS-in-JS library supporting two usage modes and used internally by MUI.

    Practical uses

    • styled-components replacement for more performance
    • Styling in a project using MUI
    • Dynamic CSS based on complex props

    Pros and cons

    What Emotion does especially well — and the limits to anticipate.

    Pros

    • More performant than styled-components
    • Two modes: styled and css
    • Compatible with React and other frameworks
    • Used by MUI (stability guarantee)

    Cons

    • Runtime overhead vs Tailwind CSS
    • Fewer resources than styled-components
    • Sometimes more complex setup

    Emotion: when it makes sense.

    Meilleur que styled-components si tu dois faire du CSS-in-JS, mais Tailwind reste plus rapide.

    Keep if

    Tu veux du CSS-in-JS plus performant que styled-components. Tu utilises MUI et veux rester cohérent avec son stack

    Challenge if

    Tu utilises Tailwind CSS (pas besoin de CSS-in-JS). Tu démarres un nouveau projet sans contrainte de CSS-in-JS

    Our verdict on Emotion.

    Why this verdict

    Decent
