canary `deno install` - can't find npm modules

deno 2.0.0-rc.1+7bfcb4d I'm having a deno.json like this

{
  "tasks": {
    "test": "vitest"
  },
  "imports": {
    "vitest": "npm:vitest@^2.0.5"
  }
}

{
  "tasks": {
    "test": "vitest"
  },
  "imports": {
    "vitest": "npm:vitest@^2.0.5"
  }
}

I run deno install I have a test like this:

import { expect, test } from "vitest"; // <- "Cannot find module 'vitest' or its corresponding type declarations.ts(2307)
function sum(a, b) {
  return a + b
}
test('adds 1 + 2 to equal 3', () => {
  expect(sum(1, 2)).toBe(3)
})

import { expect, test } from "vitest"; // <- "Cannot find module 'vitest' or its corresponding type declarations.ts(2307)
function sum(a, b) {
  return a + b
}
test('adds 1 + 2 to equal 3', () => {
  expect(sum(1, 2)).toBe(3)
})

Why can the type declarations not be found? deno install doesn't seem to make a node_modules folder by default - is that necessary for this this type to be found, or can the import mapping work? I also have the vitest.config.ts like this:

import {defineConfig} from "vitest/config";

export default defineConfig({
  test: {
    include: ['sum.test.ts']
  }
})

import {defineConfig} from "vitest/config";

export default defineConfig({
  test: {
    include: ['sum.test.ts']
  }
})

and when I run the task deno task test I get an error that "vitest/config" also can't be found:

➜ deno task test

Webgl2 in Deno i.e. for unit testing

nodejs has this challenge that there is no way to run webgl2 (or webgpu), i.e. for unit testing. There is a solution for webgl1, through the use of https://github.com/stackgl/headless-gl. Is there a way to run webgl2 in deno, headless?

byonm - force use of Deno

When I use byonm enabled in my deno.json, and say I have a vite project triggered from a package.json with i.e. "deno task dev", it appears to just my code with Node.js underneath. Is there a way to force use of deno througout, somewhat similar to what bun has with --bun flag to overwrite uses of Node.js?
