  • Trim the fat: tips for keeping bundle size small 🏋️
    3 projects | | 15 May 2022
    For example: I was using emotion to style components, but this was overkill for such a small project. There was no good reason why I needed to keep it, so I just scrapped it for old-fashioned CSS and let the bundler take care of it.
  • PurgeCSS & styled-components: Does It Work?

    On the other side of our titular question is styled-components. While I'm talking about styled-components specifically, the topics and concepts here apply to any CSS-in-JS provider (e.g. emotion). There is a smaller CSS-in-JS library called astroturf that aims to give the developer the best of all worlds, so the limitations I'll discuss later on don't apply there. But be careful with smaller projects/ones that claim you can have it all! You are wading through uncharted territory :)

    You can still use makeStyles in MUIv5 for legacy code. The function has moved to a new header '@mui/styles/makeStyles', and you should migrate to the new emotion style library.

    You can implement component-scoped, colocated styles with the help of Emotion, styled-components, or CSS Modules, among other similar libraries. My personal preference is Emotion with the css prop.

    For one, CSS-in-JS. emotion has first-class babel support, while esbuild still needs some work Basically, for esbuild / swc to work for 100% app developers, all the popular tooling with a build step must support them first.

  • Forget about styled components. Tailwind CSS is all you need.

    There are two ways to apply styling to HTML: the style attribute and using CSS. While the style attribute can only change the style of the element itself, CSS lets you target classes, siblings, children and has additional features like media queries. Using the style attribute is considered an anti-pattern as it allows no abstraction and re-usability. While I think it's true that we shouldn't use the style attribute, I believe the original arguments in favor of CSS - abstraction and re-usability - no longer hold. With the coming of the component era, CSS classes have lost their appeal. Even CSS-in-JS libraries like styled-component and emotion seem to take the wrong approach. But let's back up a little first.
