1. A Template Driven Form

• Make contacts creator component
• Add a new route
• Add a create contact method to the contacts service
• Add ngModel and ngModelGroup to the form
• Add ngSubmit and an ngForm for it to use
• Make a save method that calls the contacts service

2. Validators & Error Messages

• Add required and minlength to the name input
• If the form isn't valid...
• ...disable the save button
• ...change the field color to red
• ...add an error message in the field which tells you the minlength required
• (refactor the contacts editor to use a template driven form too)

3. Add Custom Email Validator

• Make a new directive
• Write a validation function that takes a FormControl and returns a certain object of the email is invalid
• Use the directive's providers field to add it to NG_VALIDATORS
• Add directive selector to the email input
