Write A React Switch Case Component

In React, we often find ourselves writing conditional rendering like: {condition && <Component/>}.

Examples from this Website

From my perspective, this pattern significantly impacts code maintainability and readability, yet such pattern has already became part of react syntax.

I have some thoughts about typescript as well, but we discuss that another time :)

Is There a Better Way?

During my time learning vuejs in university, I discovered its elegant solution to this problem via built-in directives. Not familiar? See the docs.

Of course, Vue.js can implement directives easily because it is based on template. Adding directives to React would be more difficult because we are going to use babel plugins.

So I will use slots, or react children, and I really make it in the end!

Here's my implementation: react-switch-case

For the sake of shadcn/ui - I have no idea how many methods that the React instance has in last several years 😅

Rather than using If-else blocks, I prefer switch cases for better readability. And the jsx syntax returns values, hence we no longer need to write break statements.

Here's a working example, just like the switch-case everyone knows 😎 react-switch-case-example
