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.

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.

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.

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.

My parents were great at making sure I got out of bed when I needed to play football on a Sunday morning and that I was ready after school to go to training on a Tuesday and Thursday. But it was never forced upon me or rammed down my throat. If it had been, I could have ended up hating sport.

I can't stand small babies. I would rather give birth to a kitten or a colt... a little pony.

Ageing is inevitable, and the idea that we can be eternally youthful is the pitfall of our society.

My daughter's got a smartphone in her hand with roughly the same power as a mainframe circa 1982, and she's running around Beijing and wants an answer as fast as she can.

The U.S. is off the spectrum in religious commitment.

Yeah, it's tough being smart and sexy, too. I have to say, I'm really not that attractive. Until I met my husband, I could not get a date. I promise you it's true. My husband Jeff Richmond saw a diamond in the rough and took me in.

No place is perfect, but I admire Oahu for its offering of the tropical and the urban, and then its Asian-inflected culture and cuisines.

As a filmmaker you aspire to want to make movies that can hopefully stand the test of time but you never know when that will happen or if that will happen.

My brother is an agent, so he is in the business. Is he my agent? No, no, no. That would never work.

It's as if inside the White House the belief in Obama's inspirational charisma is still such that every time the ugliness of brute politics intrudes, it's a startling revelation.

Tread softly; breathe peacefully; laugh hysterically.

At the end of the 1990s, we decided we should invest our best efforts to work in a sustainable way with the ingredients that the Amazon produces.

I think I'm going to spend some time learning how to be a first-time mom, and then I'll go back to work.

You are adorable mademoiselle. I study your feet with the microscope and your soul with the telescope.

Bosnia is under my skin. It's the place you cannot leave behind. I was obsessed by the nightmare of it all; there was this sense of guilt, and an anger that has become something much deeper over these last years.

Positivity always wins… Always.

To be nobody but yourself in a world thats doing its best to make you somebody else is to fight the hardest battle you are ever going to fight. Never stop fighting.

Baths she thought were just like her relationships all ooh ah in the beginning and then suddenly without warning she had to get out out out

Whether a revolution succeeds or fails people of great hearts will always be sacrificed to it.

When the mind is calm, how quickly, how smoothly, how beautifully you will perceive everything.

They're not bullying you because of you, they're bullying you because of how they are.
