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

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.

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.

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.

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

When you are 'world building,' people will oftentimes judge how well you built your world. They want to know: Is the culture believable? Does it feel like it has a history? I try very hard to pay attention to details.

The further you go in life, the more you realize what you're going to leave this Earth. It's not going to be, 'It was a great platform. It was great to win the Super Bowl,' but really and truly what you're going to leave on this Earth is the influence on others.

Peaceful, lawful protest - if it is effective - is innately disruptive of 'business as usual.' That is why it is effective.

I would lying if I said I would laugh in the face of death.

I took to heart the instructions my father drilled into my head. Respect the customer. Pay attention to her. Take her package to her car. You broke your neck to get what she wanted because you never knew when the next customer would come along.

There are a lot of goals and ambitions that I have in life, things I want to accomplish. Who knows? I mean - it could be politics one day. I want to have a life that can help people.

You do not chop off a section of your imaginative substance and make a book specifically for children, for - if you are honest - you have no idea where childhood ends and maturity begins. It is all endless and all one.

The deadpan brilliance of John McCrea has been underrepresented in music since 2004, when Cake served up 'Pressure Chief.'

I think the glue that held 'Fringe' together was the relationships.

We must never forget that while striving to leave a better planet to our kids, it is just as important that we strive to leave better kids to our planet.

At the base of it was the urge, if you wanted to play football, to knock someone down, that was what the sport was all about, the will to win closely linked with contact.

There are many things which swallow up men's thoughts while they live, which they will think little of when they are dying. Hundreds are wholly absorbed in political schemes and seem to care for nothing but the advancement of their own party. Myriads are buried in business and money matters and seem to neglect everything else but this world.

I always prefer the big laugh. That is always the objective, especially with a film like Scary Movie 2.

In my view, Indian Railways has immense untapped potential.

If someone makes you miserable more than they make you happy, then it is time to let them go, no matter how much you love them.

The ordinary experiences of aging alter and clarify your view of past, present, and future.

When I was in my teens, I was very, very keen on being the author of a book. What the book was was secondary. I wanted it to be in hardback. I didn't care how thick or thin it was, and I didn't actually care what it was about.
