Cannot `redirect` with partial URLs

[eliellis]

What version of Elysia is running?

1.2.10

What platform is your computer?

Darwin 24.1.0 arm64 arm

What steps can reproduce the bug?

Run the following:

import { Elysia } from "elysia";
import { node } from "@elysiajs/node";

const app = new Elysia({
  adapter: typeof Bun === "undefined" ? node() : undefined,
})
  .get("/home", () => {
    return "Home";
  })
  .onError(({ error }) => {
    console.log("Error", error);
  })
  .onRequest(({ request, redirect }) => {
    if (new URL(request.url).pathname !== "/home") {
      return redirect("/home");
    }
  })
  .listen(3000);

const res = await fetch("http://localhost:3000/redirect-me", {
  redirect: "manual",
});

console.log("status", res.status);

await app.stop(true);

What is the expected behavior?

The above should print status 302. Running the same sample with bun run does print status 302.

What do you see instead?

Additional information

Additionally, running the following simply hangs:

import { Elysia } from "elysia";
import { node } from "@elysiajs/node";

const app = new Elysia({
  adapter: typeof Bun === "undefined" ? node() : undefined,
})
  .get("/home", () => {
    return "Home";
  })
  .onError(() => {
    console.log("Error");
  })
  .onRequest(({ request, redirect }) => {
    if (new URL(request.url).pathname !== "/home") {
      return redirect("http://localhost:3000/home");
    }
  })
  .listen(3000);

const res = await fetch("http://localhost:3000/redirect-me", {
  redirect: "manual",
});

console.log("status", res.status);

await app.stop(true);

Running the above using bun run prints status 302.

Have you try removing the node_modules and bun.lockb and try again yet?

yes
