Answer
Communication via selectors, dependency injection, or parent-child directive references.
Quick Answer
Directives communicate through: parent-child via DI (inject parent directive in child constructor - same element or ancestor), shared service (both directives inject the same service), host binding/listener (directive reads/modifies host element), or through the component's @Input/@Output if the directive is on a component. Siblings on the same element can reference each other via DI.
