Code Inspections in Angular

Warns if components are matched on an embedded template element <ng-template>, or if more than one component is matched on any other element.

Suggests using '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.

Checks that the <ng-content> tag used for content projection doesn’t have any text or other tags in it.

Warns if component's private or protected members are accessed from its template. Such usages causes AOT compilation to fail.

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

Reports bindings to the event properties or attributes, e.g. [onclick] or [attr.onclick] instead of (click).

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

Checks that a valid Angular component is specified in the module’s bootstrap or entryComponents property.

Reports incorrect return type of an Angular binding expression.

Reports problems with i18n-* attributes.

Reports any symbols that are declared, imported or exported by an Angular module that are not modules, components, directives or pipes or can’t be used in the context of the property.

Warns about a missing event handler statement for an event binding.

Warns about Angular components, directives or pipes that are not declared in any module or declared in multiple modules.

Validates a component or directive selector property.

Reports the usage of multiple structural directives (*ngIf, *ngFor, etc) on one element.

Reports cyclic dependencies between Angular modules.

Warns about a template reference variable that is not assigned to a directive when using exportAs or is assigned to multiple directives.

Reports undefined property, event or structural directive bindings on elements.

Reports exports of undeclared or unimported components, directives and pipes from an Angular module.

Reports tags, which are defined by components or directives out of current scope.
