Creating a bun server protected by Unkey

1

Create a new Bun project

First we need a bun project, so create a new directory and init bun.
mkdir unkey-with-bun
cd unkey-with-bun
bun init -y
2

Install

Now install the @unkey/api package
bun install @unkey/api@0.35
3

Modify the server

Open up the file called index.ts and add the following code
index.ts
import { verifyKey } from "@unkey/api";

const server = Bun.serve({
  async fetch(req) {
    const key = req.headers.get("Authorization")?.replace("Bearer ", "");
    if (!key) {
      return new Response("Unauthorized", { status: 401 });
    }

    const { result, error } = await verifyKey(key);
    if (error) {
      // This may happen on network errors
      // We already retry the request 5 times, but if it still fails, we return an error
      console.error(error);
      return Response.json("Internal Server Error", { status: 500 });
    }

    if (!result.valid) {
      return new Response("Unauthorized", { status: 401 });
    }

    return Response.json(result);
  },
  port: 8000,
});
console.log(`Listening on ${server.url}`);
4

Running the server

bun run index.ts
5

Try it out

Go to https://app.unkey.com and create a new key. Then verify it with our new server:
curl http://localhost:8000 -H "Authorization: Bearer <KEY>"
It should return {"keyId":"key_id","valid":true,"meta":{},"enabled":true,"permissions":[],"code":"VALID"} and potentially more information about the key, depending on what you set up in the dashboard.
