Can you use the node REPL with Sveltekit? What about run utility scripts?

[Glench]

I'm wondering if it's possible to open a node repl and have imports and all that work out with SvelteKit? Quite often in production I have to do one-off things that require either to be in a repl or to call a script that lives outside the web server but still needs access to things like $lib/db or $app, or $env/static/private. In my previous app I just used require and relative paths, but that doesn't seem to work with SvelteKit.

You cannot use $app in node. It only exists in a vite dev or build. For $lib you need a special node loader. Ts-paths-esm-loader is one. It translates the lib to imports node can understand

Thanks for some of the info! However, maybe I should change the question to "I need access to $app — how do I make that happen?" For example, my database library needs to have access to $app/environment to figure out which db to connect to. I also need to use the db library outside of SvelteKit, e.g. in repls and scripts. What are some ways to get this to work?

Not sure about all the SK-specific imports, but $app/environment uses esm-env under the hood, so you could use that directly.

kit/packages/kit/src/runtime/app/environment.js

Lines 1 to 11 in 4ae8229

	import { BROWSER, DEV } from 'esm-env';
	/**
	* @type {import('$app/environment').browser}
	*/
	export const browser = BROWSER;
	/**
	* @type {import('$app/environment').dev}
	*/
	export const dev = DEV;

Oh good call! That looks like it should work for $app/environment.dev. I guess I should also mention that I want to use $env as well outside of SvelteKit. I edited my original post to mention that.
