The bun build creates a large self-contained executable with no optimisations. Almost like a large electron build.

Deno also provides the same functionality, but with a smaller optimized binary.

Appreciate Bun helping creating healthy competition. I feel like Deno falls under most people's radar often. More security options, faster than Node, built on web standards.

Deno's security options are very useful for AI sandboxes. Broader than node's permissions. Bun badly needs the same.

There's a PR for Bun that gives the same security but it's been sitting for months https://github.com/oven-sh/bun/pull/25911

I want to migrate an existing project to Bun but cannot until it has a security permission system in place.

I was curious:

  $ cat app.ts
  console.log("Hello, world!");
  $ cat build
  #!/usr/bin/env bash

Maybe I'm missing some flags? Bun's docs say --compile implies --production. I don't see anything in Deno's docs.

Ideally we would still only use JavaScript on the browser, personally I don't care about about the healthy competition, rather that npm actually works when I am stuck writing server side code I didn't ask for.
