The compiler is showing an error with code TS5023, indicating that the option 'strictTemplates' is not recognized

When trying to compile my Angular application (v10), I encountered the following error message.

An unexpected issue has occurred: tsconfig.json:14:5 - error TS5023: Unknown compiler option 'strictTemplates'.

14     "strictTemplates": true,
       ~~~~~~~~~~~~~~~~~

Answer №1

strictTemplates plays a crucial role in the angular compiler settings.

To properly configure strictTemplates in your project, make sure to place it under the angularCompilerOptions section within tsconfig.json file.

"angularCompilerOptions": {
  ...,
  "strictTemplates": true,
  ...
}

It is important to note that Angular version 9 or above is required for this feature to work correctly.
