This takes a long time for am empty TS file:

Steps to Reproduce:

1. Install NodeJS.
2. Create an empty folder. Open it with vsCode.
3. Create the below files with the exact content shown.
4. Run npm i in terminal to install packages.
5. Open and view index.ts file.
6. Do ctrl+shift+p and select TypeScript: Restart TS Server.
7. In the Status Bar, you would see Analyzing 'index.ts' and its dependencies (Source: TypeScript and JavaScript Language Features).

The Analyzing 'index.ts' and its dependencies spins for a very long time. The package we installed, has a lot of files, but it wasn't like this before. Things worked fine with even a ton of packages and TS files.

Here are the source files to reproduce:

index.ts: EMPTY FILE!

package.json:

{
    "dependencies": {
        "phosphor-icons-svelte": "2.0.9"
    }
}

.gitignore:

/node_modules/

Locking issues should be a crime! I mentioned the issue and it's not visible in that issue page! I can't even comment on that issue page. Don't lock issues just because you don't like them. Locking issues breaks so many basic and necessary functionalities of GitHub.

Riproduci il ritardo con il file index.ts vuoto, il package.json contenente phosphor-icons-svelte e i passaggi indicati per VS Code; inizia riavviando il server TypeScript e osservando la barra di stato. Confronta il comportamento con la issue correlata 244098. Il lavoro è completato quando la regressione è stata identificata e risolta, in modo che l’analisi venga completata rapidamente per questo progetto minimale.
