Find the ng new workspace template that emits src/main.ts (the angular-cli schematics workspace files, ending in .ts.template) and update the .catch callback to the block-bodied err: unknown form shown in the issue. Verify by generating a project with ng new, adding @angular-eslint/schematics, switching to tseslint.configs.strictTypeChecked with typed linting parser options, and running ng lint — done means both rules pass. Note an open pull request (#34268) already targets this issue, so check its status before starting.

Description

ng new generates boilerplate that contains two linting errors. They appear when linting with type information:

<path>\src\main.ts
  6:11  error  Prefer the safe `: unknown` for a `catch` callback variable                                                         @typescript-eslint/use-unknown-in-catch-callback-variable
  6:19  error  Returning a void expression from an arrow function shorthand is forbidden. Please add braces to the arrow function  @typescript-eslint/no-confusing-void-expression

The two issues can be fixed by changing the offending code to:

bootstrapApplication(App, appConfig).catch((err: unknown) => {
  console.error(err);
});

See the ts-eslint doc pages for no-confusing-void-expression and use-unknown-in-catch-callback-variable.

Minimal Reproduction
  1. Generate a new project with ng new.
  2. Run ng add @angular-eslint/schematics to add eslint.
  3. In eslint.config.js, change tseslintConfigs.recommended to tseslint.configs.strictTypeChecked.
  4. Add languageOptions.parserOptions as described in the ts-eslint docs.
  5. Run ng lint.

Anything else relevant?

TS 7.1 is expected to bring a faster typed linting API, so typed linting will become even more common.
