    If the domain is not codecraft. You won't find the timing issues that sometimes affect a template-driven form. Angular comes with a subset of built-in validators out of the box. With fc. In other words: We need a directive. So before we start coding, it's important to take some time to analyze which fields are really needed.

    A directive that adds regex pattern validation to controls marked with the pattern attribute. The regex must match the entire control value.Sometimes, a custom validator has dependencies so we need a way to inject them.

    I am using angular 6. I am trying to validate an email by using regular expression pattern but am not able. Problem is when I am trying.In a sense, instead of binding Object models to directives like in template-driven forms, we create our own instances inside a component class and construct our very own JavaScript models.
