Often times we have to create some components which perform some actions/operations on data and we require that in the parent component. Most of the times vuex
would be a better solution, but in cases where the child component's behavior has nothing to do with application state, for instance: A range-slider, date/time picker, file reader
Having individual stores for each component each time they get used gets complicated.
The angular-cli tool can help you to scaffold different parts of an angular application (components, directives, pipes, services, classes, guards, interfaces, enums and modules).
