.l-main-section

||||
h2#section-install-angular 1. Install Angular
|
||||
|
||||
p.
|
||||
In a new directory, create a <code>pubspec.yaml</code> file.
|
||||
Add angular2 and browser as dependencies,
|
||||
and add the angular2 transformer:
|
||||
[PENDING: if the transformer isn't working in time,
|
||||
remove it and use reflection in Dartium instead.
|
||||
Perhaps require Dart 1.9.]

|

browser: any
|
||||
transformers:
|
||||
- angular2
|
||||
p.
|
||||
In the same directory, run <code>pub get</code>
|
||||
to install the angular2 and browser packages
|
||||
(along with the packages they depend on):
|
||||
|
||||
pre.prettyprint.linenums

p.

PENDING: Create template? Link to pub/pubspec docs?
|

Is browser really needed?

TODO: make this an invisible note.

// STEP 2 - Import Angular ##########################
|
||||
.l-main-section
|
||||
h2#section-transpile 2. Import Angular
|
||||
|
||||
p.
|
||||
Under the same directory, create a <code>web</code> directory.
|
||||
Create a file under <code>web</code> named <code>main.dart</code>.
|
||||
Edit <code>web/main.dart</code> to import the angular2 library:
|
||||
|
||||
pre.prettyprint.linenums
|
||||
code import 'package:angular2/angular2.dart';
|
||||
|
||||
|
||||
// STEP 3 - Define a component ##########################
|
||||
.l-main-section
|
||||
|
||||
h2#section-angular-create-account 3. Define a component
|
||||
|
||||
p.
|
||||
A component is a custom HTML element.
|
||||
In this step, you create a component that has the tag <b><app></b>.
|
||||
The Dart code for a component consists of a class
|
||||
with annotations that describe the component.
|
||||
|
||||
p.
|
||||
Update <code>web/main.dart</code> to contain the following code,
|
||||
which defines the app component:
|
||||
|
||||
pre.prettyprint.linenums
|
||||
code.
|
||||
import 'package:angular2/angular2.dart';
|
||||
|
||||
@Component(
|
||||
selector: 'app'
|
||||
)
|
||||
@Template({
|
||||
inline: '<h1>Hello {{ name }}</h1>'
|
||||
})
|
||||
class AppComponent {
|
||||
String name = 'Alice';
|
||||
}
|
||||
|
||||
.l-sub-section
|
||||
h3 Annotations
|
||||
|
||||
p.
|
||||
The <code>@Component</code> annotation defines the HTML tag for the component. [PENDING: component controller?]
|
||||
The <code>selector</code> property specifies the tag. The <code>selector</code> property is a CSS selector. [PENDING: huh?]
|
||||
|
||||
p.
|
||||
The <code>@Template</code> annotation defines the template to apply to the
|
||||
component. This component uses an inline template, but external templates are
|
||||
available as well. To use an external template, specify a <code>url</code> property
|
||||
and give it the path to the HTML file.
|
||||
|
||||
pre.prettyprint.linenums
|
||||
code.
|
||||
@Component(
|
||||
selector: 'app'
|
||||
)
|
||||
@Template({
|
||||
inline: '<h1>Hello {{ name }}</h1>'
|
||||
})
|
||||
|
||||
p.
|
||||
The annotations above specify an HTML tag of <code><app></app></code>
|
||||
and a template of <code><h1>Hello {{ name }}</h1></code>.

||||
|
||||
p TODO: make double-mustaches work in text (they do work in listings)
|
||||
|
||||
.l-sub-section
|
||||
h3 The template and the component controller
|
||||
|
||||
p.
|
||||
A template has access to all the public properties and methods
|
||||
of its component controller.
|
||||
[PENDING: Do we really want to use the term "component controller"?
|
||||
If so, set it up beforehand.
|
||||
In the original text, what does "the backing" mean, and is it
|
||||
important that we keep it?]
|
||||
|
||||
pre.prettyprint.linenums
|
||||
code.
|
||||
class AppComponent {
|
||||
String name = 'Alice';
|
||||
}
|
||||
|
||||
p.
|
||||
The template above binds to a <code>name</code> property through the <code>{{ }}</code>
|
||||
syntax.The body of the constructor assigns "Alice" to the name property. When the
|
||||
template renders, Alice appears instead of <code>{{ name }}</code>.
|
||||
[TODO: fix double mustaches]

// STEP 4 - Bootstrap ##########################
|
||||
.l-main-section
|
||||
h2#section-transpile 4. Bootstrap
|
||||
|
||||
p.
|
||||
At the bottom of <code>web/main.dart</code>,
|
||||
add a <code>main()</code> function
|
||||
that calls Angular's <code>bootstrap()</code> function.
|
||||
The argument to <code>bootstrap()</code> is the name of the app class
|
||||
you defined above:
|
||||
|
||||
pre.prettyprint.linenums
|
||||
code.
|
||||
main() {
|
||||
bootstrap(AppComponent);
|
||||
}
|
||||
p.
|
||||
[PENDING: change/remove line numbers. They should start at 12.]
|
||||
|
||||
// STEP 5 - Declare the HTML ##########################
|
||||
.l-main-section
|
||||
|
||||
h2#section-angular-create-account 5. Declare the HTML
|
||||
|
||||
p.
|
||||
Create a file named <code>web/index.html</code> that contains
|
||||
the following code,
|
||||
which loads <code>main.dart</code> and instantiates the app component:
|
||||
|
||||
pre.prettyprint.linenums
|
||||
code.
|
||||
<!doctype html>
|
||||

|

<script src="packages/browser/dart.js"></script>
|
||||

|
||||
</html>
|
||||
p.
|
||||
[PENDING: When I select a bunch of code, it looks like I select the line #s too, making me fear that they'll get copied. But pasting doesn't include them. Fix!]
|
||||
|
||||
// STEP 5 - Build and run ##########################
|
||||
.l-main-section
|
||||
|
||||
h2#section-angular-run-app 5. Build and run your app
|
||||
|
||||
p.
|
||||
You have many options.
|
||||
One is to run the <code>pub serve</code>
|
||||
command in the directory
|
||||
that contains your app's <code>pubspec.yaml</code> file:
|
||||
|
||||
pre.prettyprint.linenums
|
||||
code.
|
||||
> pub serve
|
||||
Serving helloworld on http://localhost:8080
|
||||
|
||||
p.
|
||||
In the browser, go to the index file—for example,
|
||||
localhost:8080/web/index.html.
|
||||
[PENDING: This isn't working right now. Fix!]
