Setup ESLint with Deno runtime instead of node

[Mqxx]

Hey, I am currently setting um ESLint for my Deno projekt. ESLint in the CLI works without a problem, but the VS-Code extension requires a package.json file in the root of my projekt because I am using ES6 import syntax inside my eslint.config.js. The only content in my package.json is this:

package.json

{
  "type": "module"
}

I dont't use the package.json. I use the deno.json config file and I also have no commonjs in my project, everything is esm (standard).
I don't want to use the .mjs extension, because it's outdated. Is there also a way to specify where ESLint looks up the node_modules folder? Since i don't use node there is no reason to have a node_modules folder except for ESLint (requires that to work)

Here you can finde a simple ESLint example setup with Deno: github.com/DenoPlayground/eslint-example

Maybe someone can help me out.

Thanks 👍

The ESLint server can currently not been run under Deno.

Okay. Thanks for the response.

@dbaeumer Why doesn't passing "eslint.runtime": "/usr/bin/deno" work? Under the hood is it just passing CLI flags deno doesn't support?

EDIT: I see this:

EDIT: Wait is it actually execute code against the runtime? 😮

This looks more like a problem with the code the eslint server has to see whether it is running in a webpacked environment or a NodeJs commonjs one. See https://github.com/microsoft/vscode-eslint/blob/main/server/src/eslintServer.ts#L61
