Join Justin Schwartzenberger for an in-depth discussion in this video Model-driven forms, part of Angular 2 Essential Training.
- [Instructor] The model driven approach…is another way to handle building forms in Angular.…It has a lot of similarities…to the template driven approach.…But the big difference…is the form is built in the component class.…That allows you to have a contract…that your form needs to adhere to;…the ability to set up validation rules;…subscribe to field value changes,…and ultimately, unit test your form logic…without any UI layer.…So template driven gives you an easy way…to get up and running.…Whereas model driven allows you to take your forms…wherever they need to go.…
