Control flow syntax is available from Angular v17. The new syntax is baked into the template, so you don't need to import CommonModule anymore.
This schematic migrates all existing code in your application to use new Control Flow Syntax.
Run the schematic using the following command:
ng generate @angular/core:control-flowConfiguration options
The migration supports a few options for fine tuning the migration to your specific needs.
--path
By default, the migration will update your whole Angular CLI workspace. You can limit the migration to a specific sub-directory using this option.
--format
By default, the migration reformats the templates it touches. Disable this option to keep your existing template formatting.
Breaking changes
@for view reuse
If a property used in the track expression of a @for block changes but the object reference remains the same (in-place modification), Angular updates the view's bindings (including component inputs) instead of destroying and recreating the element.
This differs from *ngFor, which would execute a remount (destroy and recreate) of the element in a similar scenario if the trackBy function returned a different value.
