Entire modal definition (modal size, controller, template URL, etc.) all defined in the same location
Define modal once, reuse where needed
No need to include boilerplate modal HTML in every modal
Reduce Errors
Boilerplate HTML is abstracted away
No need to configure same modal twice
Allow Mobile-Friendly Modals
Modal manager automatically uses the mobile modal when mobile device is detected
Form Manager
Motivation
Reduce complexity
Reduce errors
Conventions
Reduce Complexity
Fields require a lot of ceremony to get set up (similar HTML, validation is in HTML instead of in form definition, every form is wired up individually to controller)
Since it has field types, we don't need to use ngPattern for validation, which is repeated throughout codebase (e.g. email pattern validation)
Reduce Errors
Removes a lot of HTML errors because the HTML is abstracted away
Easy to see what validation rules are
Uses TypeScript, meaning we have compile-time checking instead of run-time checking
When bug is found in field type, fix it in one spot and it's picked up by all applicable forms
Conventions
No need to define HTML structure for each field
Specify field type, get validation for free
Server errors are handled automatically
WAY less JS/HTML/CSS required
Very easy to change the look and feel of all forms
