Usage

This component was initially for internal use, but has been extended to support custom validation messages. Now a custom instance of this component can be passed in to override the existing validation messages.

<ts-validation-messages
  <!-- This should be the same FormControl passed to the outer form component -->
  [control]="myEmailControl"
  <!-- This is the function that will determine the messaging for errors -->
  [messagesFactory]="emailMessageFactory"
  <!-- This directive is needed to help the parent TsFormField find the custom messages -->
  tsCustomValidationMessage
></ts-validation-messages>

import { TsValidationMessageFactory } from '@terminus/ui-validation-messages';
...
emailMessageFactory: TsValidationMessageFactory = (a, b) => (a ? 'My custom message!' : null);
