Hi @fiery spoke. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave:
Astro runs on the server-side during the build process, and localStorage is a browser API, which means it's not available during the server-side rendering process. This is why you're encountering issues when trying to use localStorage directly in Astro.
However, you can use localStorage within a client-side script in your Astro component. Here's an example of how you can do this:
<script>
const saveSessionToken = (sessionToken) => {
localStorage.setItem('sessionToken', sessionToken);
};
</script>
This script will run on the client-side, where localStorage is available.
If you need to persist data across pages or sessions, you might want to consider using cookies or server-side storage. Astro provides a cookies API that allows you to get and set cookies. Here's an example:
Astro.cookies.set("sessionToken", "yourSessionToken");
const sessionToken = Astro.cookies.get("sessionToken").value;
Remember that cookies are sent with every HTTP request, so they can impact your site's performance if they're too large. They're best used for small amounts of data.
For more complex state management, you might want to consider using a state management library or a server-side storage solution.
