What are the practical differences between template-driven and reactive forms?
Here is the summary of comparision between template driven and reactive forms explained by DeborahK (Deborah Kurata) well,
Template Driven Forms Features:"
- Easy to use
- Suitable for simple scenarios and fails for complex scenarios
- Similar to AngularJS
- Two way data binding(using
[(NgModel)]
syntax) - Minimal component code
- Automatic track of the form and its data(handled by Angular)
- Unit testing is another challenge
Reactive Forms Features:
- More flexible, but needs a lot of practice
- Handles any complex scenarios
- No data binding is done (immutable data model preferred by most developers)
- More component code and less HTML markup
- Reactive transformations can be made possible such as:
- Handling an event based on a debounce time
- Handling events when the components are distinct until changed
- Adding elements dynamically
- Easier unit testing
