In the front-end code there was a service, whichDependency injection in Angular link Dependencies are services or objects that a class needs to perform its function. Dependency injection, or DI, is a design pattern in which a class requests dependencies from external sources rather than creating them. Angular's DI framework provides dependencies to a class upon instantiation.The InjectionToken from @angular/core helps us to achieve this as shown in the example above. We can then replace our hardcoded api in both service and module.ts files.Instead of providing services manually import all appropriate modules, as when providing service manually you also need to provide all its dependencies as well.
