Where to set angular strictness flags that configure how strict strictTemplates is?

I am currently converting our application to strictTemplates, and we are comming up with a huge amount of errors, some of them are more relevant than others.

So i wanted to configure the strictness of the angular type checker, and found this strictness flags in the documentation.

https://angular.io/guide/template-typecheck#troubleshooting-template-errors

Here are some examples from the docs

> strictInputTypes Whether the assignability of a binding expression to the @Input() field is checked. Also affects the inference of directive generic types.
>
> strictInputAccessModifiers Whether access modifiers such as private/protected/readonly are honored when assigning a binding expression to an @Input(). If disabled, the access modifiers of the @Input are ignored; only the type is checked. This option is false by default, even with strictTemplates set to true.
>
> strictNullInputTypes Whether strictNullChecks is honored when checking @Input() bindings (per strictInputTypes). Turning this off can be useful when using a library that was not built with strictNullChecks in mind.

[...]

The only question I could not answer was where to set them... So in which file should this flags configured, and how?

I searched the internet for a solution but did only find a huge swath of articles on how to enable --strict and what the benefits are.

As shown in the Angular docs, you have to set them in the tsconfig.json file, inside the angularCompilerOptions field.

Found the solution in this post: https://www.angular.love/en/2021/09/02/angular-compilation-restrictions-overview/

Just put these flags below the strictTemplates option:

in tsconfig.app.json

   ...
     "compilerOptions": {
       ...
       "strictNullChecks": true,
     },
     "angularCompilerOptions": {
       "strictTemplates": true,
       "strictInputTypes": true,
       "strictNullInputTypes": true
     }
    }
