Deno Runtime

Serverless edge functions powered by Deno. Execute sandboxed JavaScript and TypeScript at the edge with zero cold starts. The runtime exposes a secure subset of Deno APIs alongside OpenAI integration via the npm:openai module.

Edge-native

Runs on Deno Deploy globally. No containers, no cold starts.

Sandboxed

No filesystem, no network except allow-listed domains.

TypeScript first

Native TS support. No transpilation step required.

OpenAI SDK

Import OpenAI from npm:openai. Full chat completions API.

Try it

deno-runtime/route.ts

import OpenAI from "npm:openai";

const openai = new OpenAI({
  apiKey: Deno.env.get("OPENAI_API_KEY"),
});

export async function handler(req: Request) {
  const { prompt } = await req.json();

  const completion = await openai.chat.completions.create({
    model: "gpt-4o-mini",
    messages: [{ role: "user", content: prompt }],
  });

  return Response.json({
    result: completion.choices[0].message.content,
  });
}
