Hello, and welcome to this Angular tutorial! Today, we’re diving into one of the most essential topics for forms: validation and error messages. We'll take a basic form and provide several validation messages to help guide users. Plus, we'll level up with additional checks like email validation and even visual feedback for the form's status as a whole.
Forms are a pretty big deal in any application really and, if you didn’t already know or haven’t had much experience with it yet, Angular has you covered with the Reactive Forms Module. In this example we’ll create a basic form control and then add several enhancements to the form overall based on the validity and interaction states of the control. By the end of this tutorial, you’ll be able to quickly add your own form controls and create some very useful forms.
