Hello, I'm quite new to angular 2 and I would like to better understand the dependency injection system.
1. I have seen that we should inject them on each component when required. 2. But I have also seen that we can inject several of them at once using a grouped tag (DIRECTIVES for example). 3. I have also seen that we can inject the dependencies globally on bootstrap (for example for angular default directives or very frequently used directives). I would like to know what are the cons and pros(performance, code size, test-ability ... ) of each implementations. Which one is the recommended one or if we should combine then according to the situation. Thanks. -- You received this message because you are subscribed to the Google Groups "AngularJS" group.
