I'm using React Router as a...

library

Reproduction

• Create empty react router project.
• Use bun install command
• Show process running by adding some code to home.tsx

export async function loader({ params, request }: Route.LoaderArgs) {
  console.log(process.title)
  const hasher = new Bun.CryptoHasher("sha256");
}

• Start dev server by bun run dev

This is because of our shebang line. I'm not sure if there's a good way around this.

Instead, you can work around this by building your own small server to run the application. I do this personally (mainly so I can run with SSL enabled in dev). The guide from Remix still applies: https://remix.run/docs/en/main/start/quickstart#bring-your-own-server Just change the @remix-run imports to @react-router imports.

Bun has a way to ignore shebangs if you explicitly tell it to:
