Hi @lean gazelle. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave:
#Enable Typescript in client script with define:vars
neat stagBOT
Astro's define:vars directive is used to pass server-side variables from your component frontmatter into the client <script> or <style> tags. However, using define:vars on a <script> tag implies the is:inline directive, which means your scripts won’t be bundled and will be inlined directly into the HTML. This could be the reason why TypeScript is disabled inside the script.
Astro creates an inline script because when it bundles a script, it includes and runs the script once even if you include the component containing the script multiple times on one page. define:vars requires a script to rerun with each set of values, so Astro creates an inline script instead.
For scripts, you might want to try passing variables to scripts manually instead. You can find more information about this in the Astro documentation (https://docs.astro.build/en/guides/client-side-scripts/#pass-frontmatter-variables-to-scripts).
<script define:vars={{ getFirstName, getCookie }}>
// Your script here
</script>
Please note that the information provided is based on the Astro documentation and the behavior might change in future versions of Astro.

@neat stag how can i pass a function from server side to client side?

Let me check the knowledge base for you. One moment! :books:
Passing a function from server-side to client-side in Astro can be a bit tricky due to the nature of how Astro works. Astro does not support passing functions as props from server-side to client-side because functions can't be serialized (transferred from the server to the client).
If you try to pass a function as a prop to a framework component, it will only work during server rendering. If you try to use the function in a hydrated component (for example, as an event handler), an error will occur.
However, you can use a <script> tag in your Astro component template to send JavaScript to the browser that executes in the global scope. For example, you can't assign an event handler to an HTML element in an Astro component, but you can use a client-side script to add the event handler, like you would in vanilla JavaScript:
<button id="button">Click Me</button>
<script>
function handleClick () {
console.log("button clicked!");
}
document.getElementById("button").addEventListener("click", handleClick);
</script>
For more complex scenarios, you might want to consider using a JavaScript framework like React or Vue, which can handle client-side interactivity more seamlessly.
