Difference between Factory and Service
“Factory” and “Service” are different ways of doing DI (Dependency injection) in angular.
| Service | Factory |
|---|---|
| When we define DI using “service” it creates a new GLOBAL instance of the object and injects it in to the function. | When you define DI using a “factory” it does not create a instance. It just passes the method and later the consumer internally has to make calls to the factory. |
| We use it when you need to share a single object across the application. | When you define DI using a “factory” it does not create a instance. It just passes the method and later the consumer internally has to make calls to the factory. |
| We can use it for holding data for authenticated user details. | It is just a collection of functions like a class. |
