tslib problems in Angular 18

Question

I am creating a new project in angular 18. When entering the app.component file my text editor (vscode) shows me an error in the @Component decorator."This syntax requires an imported helper but module 'tslib' cannot be found.ts(2354)"

Now the "temporary" solution I found was in the tsconfig.json file to change the moduleResolution property from "bundler" to "node".

{
  ...
  "compilerOptions": {
    ...
    "moduleResolution": "node" //"bundler"
}

Now I don't understand exactly why this happens. I already removed all my extensions from the editor and I can't find any other solution than what I already mentioned.

• Angular CLI: 18.0.2
• Node.js: 20.14.0

I found a solution to this problem with Blunder, you just have to comment out or remove the importHelpers line from tsconfig.json and configure it in the compillerOptions of tsconfig.app.json.

tsconfig.json

tsconfig.app.json
