    Of course, we have many different ways of solving this problem. Some of the most common include pre-existing third-party icon libraries (such as Font Awesome), icons bundled into a third-party component library (like the Kendo UI Icons), or a completely custom set of icons designed and maintained by your design team. Obviously, going 100% custom will require more work (on both the design and dev side), but might be worth it to achieve a truly unique look – or if the UI will require icons for uncommon symbols or concepts.

  • stylelint

    A mighty CSS linter that helps you avoid errors and enforce conventions.

    Project mention: Speeding up the JavaScript ecosystem – The barrel file debacle | | 2023-10-09

    The “cost of loading modules” diagram shows non-linear behaviour (though you should largely ignore the curve visible in the diagram because the x axis is way off linear):

    • 0.15s ÷ 500 = 0.3ms

    • 0.31s ÷ 1000 = 0.31ms

    • 3.12s ÷ 10000 = 0.312ms

    • 16.81s ÷ 25000 = 0.6724ms

    • 48.44s ÷ 50000 = 0.9688ms

    My own observation on a Surface Book six years ago was that in Node.js under Windows, each module had about 1ms of overhead when there was warm file system cache—that is, simply bundling with Rollup saved 1ms per file. If this sort of thing interests you, quite a lot of useful stuff came out of which I filed because I was unhappy with stylelint taking over a second to import. And that must have been only in the order of one or two thousand modules, when the behaviour is still close enough to linear.
