clsx
is generally used to conditionally apply a given className
This syntax means that some class will only be applied if a given condition evaluates to true
const menuStyle = clsx({ [classes.root] : true, //always applies [classes.menuOpen] : open //only when open === true })
In this example [classes.menuOpen]
(which will evaluate to something like randomclassName123
) will only be applied if open === true
clsx
basically outputs a string
interpolation. So you don’t have to necessarily use it, although is a common practice.
There are many supported syntax that you can check in the official docs
Instead of
<div className={`${classes.foo} ${classes.bar} ${classes.baz}`} />
You can use it like this
const { foo, bar, baz } = classes const style = clsx(foo, bar, baz) return <div className={style} />
