Join Justin Schwartzenberger for an in-depth discussion in this video Dependency injection, part of Angular 2 Essential Training (2016).
- At the heart of Angular, and one of its most powerful…features as a framework, is how it brings dependency…injection to Javescript.…Dependency injection, or DI for short, is the concept of…inversion of control, or IOC for short,…where you architect code in a way…that you provide modules with other modules…it needs to get some work done instead of having your…modules go out and get other modules on their own.…DI allows you to write decoupled code that is easier…to unit test and to work with.…
In the Angular world, this allows you to write these modular…components and even services within your applications…and simply tell Angular what you want to use…and where you want to use them.…Angular will handle constructing instances of those…and sending them to your code where needed.…The most common place you use DI is in…your class constructors. So constructors for components,…directives, pipes and services you write can leverage…the way Angular does DI.…You can simply declare types on your constructor parameters…with some help from TypeScript…
