An example of an AI chatbot conversation about Angular's built-in form validators.
What are the built-in validators in Angular forms?
Angular provides several built-in validators like required, minLength, maxLength, and pattern. These help in form validation.
Can you explain how to use the required validator?
Sure! To use the required validator, you can add it to your form control like this: this.formControl = new FormControl('', Validators.required);.
What happens if the required validator fails?
If the required validator fails, the form control will be marked as invalid, and you can display an error message to the user.
Are there any custom validators I can create?
Yes, you can create custom validators by defining a function that returns either null (valid) or an error object (invalid).
