that you [bootstrap](#main) to launch the application.
|
||||
You can call it anything you want. The conventional name is `AppModule`.
|
||||
|
||||
The [setup](setup.html) instructions produce a new project with the following minimal `AppModule`.
|
||||
You'll evolve this module as your application grows.

After the `import` statements, you come to a class adorned with the
|
||||
**`@NgModule`** [_decorator_](glossary.html#decorator '"Decorator" explained').
|
||||
|
||||
The `@NgModule` decorator identifies `AppModule` as an Angular module class (also called an `NgModule` class).
|
||||
`@NgModule` takes a _metadata_ object that tells Angular how to compile and launch the application.
|
||||
|
||||
* **_imports_** — the `BrowserModule` that this and every application needs to run in a browser.
|
||||
* **_declarations_** — the application's lone component, which is also ...
|
||||
* **_bootstrap_** — the _root_ component that Angular creates and inserts into the `index.html` host web page.
|
||||
|
||||
The [Angular Modules (NgModules)](ngmodule.html) guide dives deeply into the details of Angular modules.
|
||||
All you need to know at the moment is a few basics about these three properties.
|
||||
|
||||
a#imports
|
||||
:marked
|
||||
### The _imports_ array
|
||||
|
||||
Angular modules are a way to consolidate features that belong together into discrete units.
|
||||
Many features of Angular itself are organized as Angular modules.
|
||||
HTTP services are in the `HttpModule`. The router is in the `RouterModule`.
|
||||
Eventually you may create a feature module.
|
||||
|
||||
Add a module to the `imports` array when the application requires its features.
|
||||
|
||||
_This_ application, like most applications, executes in a browser.
|
||||
Every application that executes in a browser needs the `BrowserModule` from `@angular/platform-browser`.
|
||||
So every such application includes the `BrowserModule` in its _root_ `AppModule`'s `imports` array.
|
||||
Other guide and cookbook pages will tell you when you need to add additional modules to this array.
|
||||
|
||||
.alert.is-important
|
||||
:marked
|
||||
**Only `NgModule` classes** go in the `imports` array. Don't put any other kind of class in `imports`.
|
||||
|
||||
.l-sub-section
|
||||
:marked
|
||||
Don't confuse the `import` statements at the top of the file with the Angular module's `imports` array.
|
||||
They have different jobs.
|
||||
|
||||
The _JavaScript_ `import` statements give you access to symbols _exported_ by other files
|
||||
so you can reference them within _this_ file.
|
||||
They have nothing to do with Angular and Angular knows nothing about them.
|
||||
|
||||
The _module's_ `imports` array tells Angular about specific Angular modules — classes decorated with `@NgModule` —
|
||||
that the application needs to function properly.
|
||||
a#declarations
|
||||
:marked
|
||||
### The _declarations_ array
|
||||
|
||||
You must declare _every_ component in one (and _only one_) `NgModule` class.
|
||||
You tell Angular which components belong to the `AppModule` by listing it in the module's `declarations` array.
|
||||
As you create more components, you'll add them to `declarations`.
|
||||
|
||||
You'll learn to create two other kinds of classes —
|
||||
[directives](attribute-directives.html) and [pipes](pipes.html) —
|
||||
that you must also add to the `declarations` array.
|
||||
|
||||
.alert.is-important
|
||||
:marked
|
||||
**Only _declarables_** — _components_, _directives_ and _pipes_ — belong in the `declarations` array.
|
||||
Don't put any other kind of class in `declarations`; _not_ `NgModule` classes, _not_ service classes, _not_ model classes.
|
||||
|
||||
a#bootstrap-array
|
||||
:marked
|
||||
### The _bootstrap_ array
|
||||
|
||||
You launch the application by [_bootstrapping_](#main) the root `AppModule`.
|
||||
Among other things, the _bootstrapping_ process creates the component(s) listed in the `bootstrap` array
|
||||
and inserts each one into the browser DOM.
|
||||
|
||||
Each bootstrapped component is the base of its own tree of components.
|
||||
Inserting a bootstrapped component usually triggers a cascade of component creations that fill out that tree.
|
||||
|
||||
While you can put more than one component tree on a host web page, that's not typical.
|
||||
Most applications have only one component tree and they bootstrap a single _root_ component.
|
||||
|
||||
You can call the one _root_ component anything you want but most developers call it `AppComponent`.
|
||||
|
||||
Which brings us to the _bootstrapping_ process itself.
|
||||
|
||||
a#main
|
||||
l-main-section
|
||||
:marked
|
||||
## Bootstrap in _main.ts_
|
||||
|
||||
There are many ways to bootstrap an application.
|
||||
The variations depend upon how you want to compile the application and where you want to run it.
|
||||
|
||||
In the beginning, you will compile the application dynamically with the _Just-in-Time (JiT)_ compiler
|
||||
and you'll run it in a browser. You can learn about other options later.
|
||||
|
||||
The recommended place to bootstrap a JiT-compiled browser application is in a separate file
|
||||
in the `app` folder named `app/main.ts`
|
||||
+makeExample('setup/ts/app/main.ts','','app/main.ts')(format='.')
|
||||
:marked
|
||||
This code creates a browser platform for dynamic (JiT) compilation and
|
||||
bootstrap's the `AppModule` described above.
|
||||
|
||||
The _bootstrapping_ process sets up the execution environment,
|
||||
digs the _root_ `AppComponent` out of the module's `bootstrap` array,
|
||||
creates an instance of the component and inserts it within the element tag identified by the component's `selector`.
|
||||
|
||||
The `AppComponent` selector — here and in most documentation samples — is `my-app`
|
||||
so Angular looks for a `<my-app>` tag in the `index.html` like this one ...
|
||||
+makeExample('setup/ts/index.html','my-app')(format='.')
|
||||
:marked
|
||||
... and displays the `AppComponent` there.
|
||||
|
||||
This file is very stable. Once you've set it up, you may never change it again.
|
||||
|
||||
a#quickstart-appmodule
|
||||
l-main-section
|
||||
:marked
|
||||
## QuickStart's _AppModule_
|
||||
Every Angular application must have a root `NgModule`, even the [QuickStart](../quickstart.html).
|
||||
You didn't see it but it was there.
|
||||
|
||||
A script in the `index.html` generated a hidden `AppModule` and bootstrapped it for you
|
||||
so you could focus on the `AppComponent` and discover the _essential Angular_ more quickly.
|
||||
|
||||
If you're feeling adventurous, add your own `AppModule` and `main.ts` to the
|
||||
live code in the _QuickStart_ plunker.
|
||||
|
||||
Remove the following `<script>` tag from the `index.html` and see _your_ work in action.
|
||||

## Learning path
|
||||
|
||||
You don't have to read the guide straight through. Most pages stand on their own.
|
||||
|
||||
For those new to Angular, the recommended learning path runs through the *Guide* section:
|
||||
|
||||
1. For the big picture, read the [Architecture](architecture.html) overview.
|
||||
|
||||
1. Try [QuickStart](../quickstart.html). QuickStart is the "Hello, World" of Angular.
|
||||
It shows you how to set up the libraries and tools you'll need to write *any* Angular app.
|
||||
|
||||
1. Take the *Tour of Heroes* [tutorial](../tutorial), which picks up where QuickStart leaves off,
|
||||
and builds a simple data-driven app. The app demonstrates the essential characteristics of a professional application:
|
||||
a sensible project structure, data binding, master/detail, services, dependency injection, navigation, and remote data access.
|
||||
|
||||
1. [Displaying Data](displaying-data.html) explains how to display information on the screen.
|
||||
|
||||
1. [User Input](user-input.html) covers how Angular responds to user behavior.
|
||||
|
||||
1. [Forms](forms.html) handles user data entry and validation within the UI.
|
||||
|
||||
1. [Dependency Injection](dependency-injection.html) is the way to build large, maintainable applications
|
||||
from small, single-purpose parts.
|
||||
|
||||
1. [Template Syntax](template-syntax.html) is a comprehensive study of Angular template HTML.
|
||||
|
||||
After reading the above sections, you can skip to any other pages on this site.

||||

|
||||
The rest of the pages highlight key points in code rather than explain each step necessary to build the sample.

Every Angular app has a **root module** class.

## Setup a local development environment
|
||||
The <live-example name=quickstart>QuickStart live-coding</live-example> example is an Angular _playground_.
|
||||
It's not where you'd develop a real application.
|
||||
You [should develop locally](#why-locally "Why develop locally") on your own machine ... and that's also how we think you should learn Angular.
|
||||
|
||||
Setting up a new project on your machine is quick and easy with the **QuickStart seed**,
|
||||
maintained [on github](https://github.com/angular/quickstart "Install the github QuickStart repo").
|
||||
|
||||
Make sure you have [node and npm installed](#install-node "What if you don't have node?").
|
||||
Then ...
|
||||
1. Create a project folder (you can call it <span ngio-ex>quickstart</span> and rename it later).
|
||||
1. [Clone](#clone "Clone it from github") or [download](#download "download it from github") the **QuickStart seed** into your project folder.
|
||||
1. [Install the _npm_ packages](#install-node "What if you don't have node?").
|
||||
1. Run `npm start` to launch the sample application.
|
||||

||||

### Clone
|
||||

||||
Perform the _clone-to-launch_ steps with these terminal commands.

||||

|

git clone https://github.com/angular/quickstart.git quickstart

## What's in the QuickStart seed?
|
||||
|
||||
The **QuickStart seed** contains the same application as the QuickStart playground
|
||||
and even has <live-example>its own _playground_</live-example>
|
||||
that accomodates development of richer examples in a live coding environment.
|
||||
|
||||
But it's true purpose is to provide a solid foundation for _local_ development.
|
||||
Consequently, there are _many more files_ in the project folder on your machine,
|
||||
most of which you can [learn about later](setup-systemjs-anatomy.html "Setup Anatomy").
|
||||
|
||||

||||

## Appendix: _node_ and _npm_
|
||||
|
||||
Node.js and npm are essential to modern web development with Angular and other platforms.
|
||||
Node powers client development and build tools.
|
||||
The _npm_ package manager, itself a _node_ application, installs JavaScript libraries.
|
||||
|
||||
<a href="https://docs.npmjs.com/getting-started/installing-node" target="_blank" title="Installing Node.js and updating npm">
|
||||
Get them now</a> if they're not already installed on your machine.
|
||||
|
||||
**Verify that you are running node `v4.x.x` or higher and npm `3.x.x` or higher**
|
||||
by running the commands `node -v` and `npm -v` in a terminal/console window.
|
||||
Older versions produce errors.
|
||||
|
||||
We recommend [nvm](https://github.com/creationix/nvm) for managing multiple versions of node and npm.
|
||||
You may need [nvm](https://github.com/creationix/nvm) if you already have projects running on your machine that
|
||||
use other versions of node and npm.

## Appdendix: Why develop locally
|
||||
|
||||
<live-example>Live coding</live-example> in the browser is a great way to explore Angular.
|
||||
|
||||
Links on almost every documentation page open completed samples in the browser.
|
||||
You can play with the sample code, share your changes with friends, and download and run the code on your own machine.
|
||||
|
||||
The [QuickStart](../quickstart.html "Angular QuickStart Playground") shows just the `AppComponent` file.
|
||||
It creates the equivalent of `app.module.ts` and `main.ts` internally _for the playground only_.
|
||||
so the reader can discover Angular without distraction.
|
||||
The other samples are based on the QuickStart seed.
|
||||
|
||||
As much fun as this is ...
|
||||
* you can't ship your app in plunker
|
||||
* you aren't always online when writing code
|
||||
* transpiling TypeScript in the browser is slow
|
||||
* the type support, refactoring, and code completion only work in your local IDE
|
||||
|
||||
Use the <live-example><i>live coding</i></live-example> environment as a _playground_,
|
||||
a place to try the documentation samples and experiment on your own.
|
||||
It's the perfect place to reproduce a bug when you want to
|
||||
<a href="https://github.com/angular/angular.io/issues/new" target="_blank" title="File a documentation issue">file a documentation issue</a> or
|
||||
<a href="https://github.com/angular/angular/issues/new" target="_blank" title="File an Angular issue">file an issue with Angular itself</a>.
|
||||
|
||||
For real development, we strongly recommend [developing locally](#develop-locally).

Angular applications are made of _components_.
|
||||
A _component_ is the combination of an HTML template and a component class that controls a portion of the screen.
|
||||
|
||||
+ifDocsFor('ts')
|
||||
Every component begins with a `@Component` [_decorator_](glossary.html#decorator '"Decorator" explained') function
|
||||
that takes a _metadata_ object. The metadata describe how the HTML template and component class work together.
|
||||
|
||||
The `selector` property tells Angular to display the component inside a custom `<my-app>` tag in the `index.html`.
|
||||
+makeExample('index.html','my-app','index.html (inside <body>)')(format='.')
|
||||
:marked
|
||||
The `template` property defines a message inside an `<h1>` header.
|
||||
The message starts with "Hello" and ends with `{{name}}`
|
||||
which is an Angular [interpolation binding](guide/displaying-data.html) expression.
|
||||
At runtime, Angular replaces `{{name}}` with the value of the component's `name` property.
|
||||
|
||||
Change the component class's `name` property from `'Angular'` to `'World'` and see what happens.
|
||||

||||
Binding is one of many Angular features you'll discover in this documentation.

This is the entry point to your application.

Since the QuickStart application is a web application that runs in a browser, your root module

[`BrowserModule`](../latest/api/platform-browser/index/BrowserModule-class.html)

from `@angular/platform-browser` to the `imports` array.

This is the smallest amount of Angular that is needed for a minimal application to run in the

The QuickStart application doesn't do anything else, so you don't need any other modules. In a real

Every Angular application has at least one component: the _root component_, named `AppComponent`
|
||||
here.
|

Components are the basic building blocks of Angular applications. A component controls a portion

of the screen—a *view*—through its associated template.

The QuickStart application has the same essential structure as any other Angular component:

||||
|
||||
* **An import statement**. Importing gives your component access to
|
||||
Angular's core [`@Component` !{_decorator_function}](./api/core/index/Component-decorator.html).
|
||||
* **A @Component #{_decorator}** that associates *metadata* with the
|
||||
`AppComponent` component class:
|
||||
|
||||
- a *selector* that specifies a simple CSS selector for an HTML element that represents
|
||||
the component.
|
||||
- a *template* that tells Angular how to render the component's view.
|
||||
* **A component class** that controls the appearance and behavior of a view
|
||||
through its template. Here, you only have the root component, `AppComponent`. Since you don't
|
||||
need any application logic in the simple QuickStart example, it's empty.

This code initializes the platform that your application runs in, then uses the platform to

### Why create separate *<span ngio-ex>main.ts</span>*<span if-docs="ts">, app module</span> and app component files?
|
||||
|

App bootstrapping is a separate concern from<span if-docs="ts"> creating a module or</span>

presenting a view. Testing the component is much easier if it doesn't also try to run the entire application.

Because the QuickStart application runs directly in the browser, `main.ts` imports the
|
||||
`!{_platformBrowserDynamicVsBootStrap}` function from `#{_angular_browser_uri}`, not
|
||||
`#{_angular_core_uri}`. On a mobile device, you might load a !{_moduleVsComp} with
|
||||
[Apache Cordova](https://cordova.apache.org/) or
|
||||
[NativeScript](https://www.nativescript.org/), using a bootstrap function that's specific
|
||||
to that platform.

* A static file server called _lite-server_ that loads `index.html` in a browser
|
||||
and refreshes the browser when application files change.
|
||||
|
||||
In a few moments, a browser tab should open and display the following:
|
||||
|
||||
figure.image-display
|
||||
img(src='/resources/images/devguide/quickstart/hello-angular.png' alt="Output of QuickStart app")

|

The TypeScript compiler and `lite-server` will detect your change, recompile the TypeScript into JavaScript,
|
||||
refresh the browser, and display your revised message.
|
||||
|
||||
Close the terminal window when you're done to terminate both the compiler and the server.

## What next?
|
||||
This first application doesn't do much. It's basically "Hello, World" for Angular.
|
||||
|
||||
You wrote a little Angular component, created a simple `index.html`, and launched with a
|
||||
static file server.
|
||||
|
||||
+ifDocsFor('ts')
|
||||
:marked
|
||||
You also created the basic application setup that you'll re-use for other
|
||||
sections in this guide. From here, the changes you'll make in the
|
||||
`package.json` or `index.html` files are only minor updates to add libraries or some css
|
||||
stylesheets. You also won't need to revisit module loading again.
|
||||

|
||||
To take the next step and build a small application that demonstrates real features that you can
|
||||
build with Angular, carry on to the [Tour of Heroes tutorial](./tutorial)!
