Referenced Project May Not Disable Emit

[brendanmatkin]

Describe the bug

With a brand new svelte-ts app created using create-vite, the tsconfig.json file shows an error at "references": [{ "path": "./tsconfig.node.json" }]: Referenced project '<path to app>/tsconfig.node.json' may not disable emit.ts

The change is relatively recent: cf3f40c

Possibly the correct setting is emitDeclarationOnly instead of noEmit (tsc maybe depends on the .d.ts files of the referenced project to split up the work, and noEmit prevents those from being created? As per this discussion). The error goes away with emitDeclarationOnly: true, but does that mean tsc is doing extra work that esbuild is already handling?

pnpm build and pnpm check succeed, it's just an annoying error (but maybe is indicative of some type checking actually not happening correctly?). Maybe it is actually a VSCode error?

Reproduction

https://stackblitz.com/edit/vitejs-vite-vrcca7?file=tsconfig.json

Steps to reproduce

pnpm create vite my-app
cd my-app
pnpm install

Then open in VSCode, and look at tsconfig.json. It should have a red squiggle on line 20.

OR run npx tsc

If you change line 9 of tsconfig.node.json from "noEmit": true to "emitDeclarationOnly": true and save, the error goes away (but maybe this setting is undesirable?).

If I do everything again with npm, the result is the same.

NOTE: the error doesn't show in the editor in stackblitz using npm or pnpm, but it does if you run npx tsc!
