In an Astro site page I wanted to add a bit of interactivity, and chose React.

I created the component, and inside it I had a pro state variable that was true or false and showed different things based on this state:

import { useState } from 'react'

export default function TabBar() {
  const [pro, setPro] = useState(false)

	return (
    <div>
      {pro ? <p>pro</p> : <p>free</p>}
    </div>
  )
}

and I used it like this:

<TabBar client:load />

(client:load otherwise it’s server-rendered at build time and not interactive).

So far so good.

But I wanted to pass multiple Astro components to this, so here’s what I did:

<TabBar client:load>
  <div slot='free'>
    <Free />
  </div>
  <div class='pt-2 mb-20' slot='pro'>PRO</div>
</TabBar>

Inside the React component, those slots are available through {props.pro} and {props.free}.

import { useState } from 'react'

export default function TabBar(props) {
  const [pro, setPro] = useState(false)

	return (
    <div>
      {pro ? props.pro : props.free}
    </div>
  )
}
