How can I generate a random uuid? Using Astro and Node adapter.

Hi @austere lynx. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave:

#

The knowledge sources you provided don’t mention UUID generation specifically, nor do they show concrete examples of using Node’s crypto/uuid APIs with Astro.

They do confirm that:

  • You’re using the Node adapter, which runs your code in a Node.js environment.[@astrojs/node guide]
  • Astro supports Node built-ins via the node: prefix (with some adapter/runtime caveats).[Node builtins]

Given that, the usual Node approach should work in routes/pages that run on the server (e.g. output: 'server' or prerender = false):

// Example: src/pages/random-uuid.js
export const prerender = false; // ensure this runs on the server

export async function GET() {
  // In Node 18+, you can use crypto.randomUUID()
  const { randomUUID } = await import('node:crypto');
  const id = randomUUID();

  return new Response(
    JSON.stringify({ uuid: id }),
    { headers: { 'Content-Type': 'application/json' } }
  );
}

Because the docs don’t explicitly show UUID usage, if you run into issues, check:

  • Your Node version (for crypto.randomUUID() support).
  • That the route is actually rendered on-demand (server) and not fully prerendered. [On‑demand rendering]

Note: you can ask me a follow up question by @ mentioning me again :speech_balloon:
