NgModules can import functionality from other NgModules, and allow their own functionality to be exported and used by other NgModules. For example, to use the router service in your app, you import the Router NgModule.

Webpack has become the defacto standard when building Angular applications, you can check an introduction to Webpack post here on the Angular documentation.

System.js System was heavily used in the beginning whilst Angular was being built and during the release candidate stages before official release, however the team have switched to advocating Webpack instead due to it being much more powerful.

Angular CLI The Angular CLI was built to help scaffold new projects, create components and help with deployment. Underneath it utilises Webpack for you.

The basic building blocks of an Angular application are NgModules, which provide a compilation context for components.

An Angular app is defined by a set of NgModules.

An app always has at least a root module that enables bootstrapping, and typically has many more feature modules.

Components define views, which are sets of screen elements.

Components use services, which provide specific functionality not directly related to views.

Service providers can be injected into components as dependencies, making your code modular, reusable, and efficient.

Both components and services are simply classes, with decorators that mark their type and provide metadata that tells Angular how to use them.

Metadata is a way of processing the class. A class will be a class unless we tell Angular that is a Component, Service etc. Decorators that mark their type and provide the metadata that tells Angular how to use them.

The metadata for a component class associates it with a template that defines a view.

The metadata for a service class provides the information Angular needs to make it available to components through dependency injection (DI).

Angular provides the Router service to help you define navigation paths among views.

An NgModule declares a compilation context for a set of components that is dedicated to an application domain, a workflow, or a closely related set of capabilities.

Organising your code into distinct functional modules helps in managing development of complex applications. This technique lets you take advantage of lazy-loading—that is, loading modules on demand—

Every Angular app has a root module, conventionally named AppModule, which provides the bootstrap mechanism that launches the application.

A template combines ordinary HTML with Angular directives and binding markup that allow Angular to modify the HTML before rendering it for display.

Angular |-- App1 | |-- Module (root App BS module) | |-- * View * (n) | +-- Component | +-- Template | |-- Service (n) | |-- Module (n) |-- App2 (n)

I tested in the top percentile for IQ, but I couldn't tie my shoes or really ride a bike without training wheels until I was almost 7.

Contentions for trifles can get but a trifling victory.

There is not now, nor I suspect will there ever be, a le Carre novel with ninjas in it. Most serious novelists are wary of including ninjas in their writing. That's a shame, because many much-admired works of modern fiction could benefit from a few.

After being on the court for six hours, being on TV is very glamorous and fun for me. But tennis is always going to be my priority. It's not going to be this thing when all of a sudden TV will get in the way of that.

I'm not a great believer in marriages as an institution, or even in very long term relationships. I'm not sure we're built that way.

The heart was made to be broken.

The Australian people want to help build this country into a great nation. This budget... has not realized the capacity of the Australian people. It has underestimated them. It has let us down.

The problem is Twitter is designing the metaphorical equivalent of a Toyota Prius. A car for the masses. While I want a Formula One race car.

Slight not what's near through aiming at what's far.

I would love to play a crazy Russian spy, run with a gun. That's something I would love to do.

The subsistence level is only a conventional idea, and conventions change.

It's phenomenally important to me that, if I'm going to be spending years on a project, I need to be interested in the whole thing. I'm not there to be on my own. And if I'm going to be with these people, I'd best be interested in their work.

I still can't really believe it. They just told us, 'Hey, you're doing great. Keep it up.'

Think of your family today and every day thereafter, don't let the busy world of today keep you from showing how much you love and appreciate your family.

Belief, like love, must be voluntary.

Never in my life did I think I would be congratulated by Mick Jagger for achieving anything.

I love being on the beach - it's my favourite place. I can chill out, read, listen to music, play with my daughter.

I usually have a lip balm in my bag and mascara as well. I don't really wear much make-up, but I like mascara because I've got fair colouring.

I would love to go back to Broadway.

Cynics will say there are no good people out there. And if you read the papers and watch TV news you could be convinced of that. But there are good people.

If you have a chance to accomplish something that will make things better for people coming behind you, and you don't do that, you are wasting your time on this earth.

Raising taxes won't create private sector jobs.

Olivier was another case of a genius, who couldn't understand why anybody would have any trouble doing this, because for him it came so easily.

You have to know how to keep things in perspective.
