When to use NO_ERRORS_SCHEMA and CUSTOM_ELEMENTS_SCHEMA?

When we have to use NO_ERRORS_SCHEMA and CUSTOM_ELEMENTS_SCHEMA in Angular?

What do they mean? Is it config for CSS styles?

Solution

  • See https://angular.io/api/core/NO_ERRORS_SCHEMA => Defines a schema that allows any property on any element.

    And https://angular.io/api/core/CUSTOM_ELEMENTS_SCHEMA => Defines a schema that allows an NgModule to contain the following: Non-Angular elements named with dash case (-). Element properties named with dash case (-). Dash case is the naming convention for custom elements.

    So NO_ERRORS_SCHEMA is less restrictive, but anything unknown in the template is accepted
