Code Inspections in Angular

Reports a component that is matched on an embedded template element <ng-template> or multiple components matched on any other element.

Suggests using the ng add command to install the dependency.

ng add will use the package manager to download it and invoke a schematic which can update your project with configuration changes, add additional dependencies (e.g. polyfills), or scaffold package-specific initialization code.

Reports a text or tag occurrence inside a <ng-content> tag used for content projection.

Reports accessing a private or protected member of a component from the component's template. Such usages result in AOT compilation failure.

Reports a component that doesn’t have an associated template or uses both template and templateUrl properties.

Reports a binding to an event property or attribute, for example, [onclick] or [attr.onclick] instead of (click).

Reports an invalid assignment of an animation trigger. To attach an animation to an element, use [@triggerName]="expression" or an attribute without a value @triggerName.

Reports incorrect return type of an Angular binding expression.

Reports a problem with a i18n-* attribute.
