Visual Change Detection and Component Tree

Angular Profiler provides multiple ways to help us debugging over-triggered change detection in our Angular application.

1. Highlight the components that triggered CD and indicate CD times with different colors.

2. Visual detecting changes in a component tree

The component tree will show you how angular components are rendered and updated

Inspect and change component state

Select a component in the component tree, then you can see all the states of this component in the properties tab. You can update the components right away without changing your codes and waiting webpack to compile to see your changes anymore.
