Control Flow Syntax migration

Angular v17 introduces a new control flow syntax. This migration replaces the existing usages of *ngIf, *ngFor, and *ngSwitch to their equivalent block syntax. Existing ng-templates are preserved in case they are used elsewhere in the template. It has the following option:

• path - Relative path within the project that the migration should apply to. Can be used to migrate specific sub-directories individually. Defaults to the project root.

Before

import {Component} from '@angular/core';

@Component({
  template: `<div><span *ngIf="show">Content here</span></div>`,
})
export class MyComp {
  show = false;
}

After

import {Component} from '@angular/core';

@Component({
  template: `<div>
    @if (show) {
      <span>Content here</span>
    }
  </div>`,
})
export class MyComp {
  show = false;
}
