Bun plugin to use SvelteKit imports in standalone scripts

[mquandalle]

When using Bun with a SvelteKit application, you often need to run standalone scripts that reuse code from your app. But SvelteKit uses special module imports that don't work outside the SvelteKit context:

// In SvelteKit:
import { DATABASE_URL } from '$env/static/private';

// In Bun scripts:
const DATABASE_URL = process.env.DATABASE_URL; // or Bun.env.DATABASE_URL

This makes it hard to share utility functions between your SvelteKit app and CLI scripts without duplicating code or creating environment-specific wrappers.

I created a simple Bun plugin that resolves SvelteKit's virtual modules, allowing you to use the same imports everywhere:

• $env/static/private → maps to Bun.env
• $app/environment → returns { dev: true }

Now you can write shared code once and use it in both your SvelteKit app and Bun scripts without any modifications.
