In Angular(2/4/5) How to share the data between the components?

Answer 1

In Angular, we can share data in 2 ways.

1) Using Service
2) Using @Input/@Output

1) Using Service - Create a service with getter & setter. Access the service in components through dependency injection.

2) Using @Input/@Output
Input and Output are two decorators in Angular responsible for communication between two components

@Input - Input used to pass the data from parent to child

@Output - Output used to pass the data from child to parent
