Comment by Rudolf Erasmus on "In angular, whenever I create a service and use it multiple components using dependency injection. Does service instantiated every time I use in multiple component?" | Hashnode
Afaik you will get an instance per module use, so if you use the service in 2 modules you would have 2 instances. If you put the service in its own module (not app. module) then you will have only one instance across the app.
