Compiling Bun App

[kerematam]

Bun provides "--compile" flag for generating a standalone binary from a TS/JS file.

I am working on basic-start example.

To build bun; i came across and tried the approach described in this blog post:
https://www.josephlozano.dev/blog/single-binary-bun

However, it didn’t work for me, and I suspect the method is now outdated. The post suggests app.config.ts:

import { defineConfig } from "@tanstack/start/config";
server: { preset: "bun", inlineDynamicImports: true, serveStatic: "inline" }

In my project, @tanstack/start/config doesn’t exist, and there’s no app.config.ts. Looks like current Start doesn’t expose that config path. So Idk how do we override nitro configs.

My vite.config.ts:

export default defineConfig({
  server: {
    port: 3000,
  },
  plugins: [
    tsConfigPaths({
      projects: ["./tsconfig.json"],
    }),
    tanstackStart({
      target: "bun",
      customViteReactPlugin: true,
    }),
    viteReact(),
  ],
});

Error once i've tried to build file under .output folder:

$ bun build .output/server/index.mjs --compile
