Hello

When set aot: true:

import { Elysia } from "elysia";

const app = new Elysia({ aot: true })
  .headers({
    "X-Powered-By": "Elysia",
  })
  .get("/", () => "Hello").listen(3000);

console.log(
  `🦊 Elysia is running at ${app.server?.hostname}:${app.server?.port}`
);

Hello

What is the expected behavior?

When aot: false, it still works

What do you see instead?

No response

Additional information

Actually it was found in @elysiajs/cors 1.0.4, when aot: false (Which is necessary for Cloudflare Worker), the OPTION method did not response properly, but in 1.0.2, it works well.

To reproduce:

bun create elysia app
cd app/
bun i @elysiajs/cors@1.0.4

// src/index.ts
import cors from "@elysiajs/cors";
import { Elysia } from "elysia";

const app = new Elysia({ aot: false })
  .use(cors({
    aot: false,
    allowedHeaders: [
      'authorization',
      'content-type'
    ],
  }))
  .get("/", () => "Hello Elysia").listen(3000);

console.log(
  `🦊 Elysia is running at ${app.server?.hostname}:${app.server?.port}`
);

Hello Elysia%

But when downgradle to @elysiajs/cors@1.0.2 or just enable aot:

bun i @elysiajs/cors@1.0.2

it works well.

# Downgradle to 1.0.2
