Build HTML AST's and render them to HTML.
This can be used as an internal DSL, i.e. for a templating engine.
## Installation
In your `pubspec.yaml`:
```yaml
dependencies:
angel3_html_builder: ^2.0.0
```
## Usage
```dart
import 'package:angel3_html_builder/angel3_html_builder.dart';
void main() {
// Akin to React.createElement(...);
var $el = h('my-element', p: {}, c: []);
// Attributes can be plain Strings.
h('foo', p: {
'bar': 'baz'
});
// Null attributes do not appear.
h('foo', p: {
'does-not-appear': null
});
// If an attribute is a bool, then it will only appear if its value is true.
h('foo', p: {
'appears': true,
'does-not-appear': false
});
// Or, a String or Map.
h('foo', p: {
'style': 'background-color: white; color: red;'
});
h('foo', p: {
'style': {
'background-color': 'white',
'color': 'red'
}
});
// Or, a String or Iterable.
h('foo', p: {
'class': 'a b'
});
h('foo', p: {
'class': ['a', 'b']
});
}
```
Standard HTML5 elements:
```dart
import 'package:angel3_html_builder/elements.dart';
void main() {
var $dom = html(lang: 'en', c: [
head(c: [
title(c: [text('Hello, world!')])
]),
body(c: [
h1(c: [text('Hello, world!')]),
p(c: [text('Ok')])
])
]);
}
```
Rendering to HTML:
```dart
String html = StringRenderer().render($dom);
```
Example with the [Angel](https://github.com/dukefirehawk/angel/tree/angel3) server-side framework,
which has [dedicated html_builder support](https://github.com/dukefirehawk/angel/tree/html):
```dart
import 'dart:io';
import 'package:angel3_framework/angel3_framework.dart';
import 'package:angel3_html_builder/elements.dart';
configureViews(Angel app) async {
app.get('/foo/:id', (req, res) async {
var foo = await app.service('foo').read(req.params['id']);
return html(c: [
head(c: [
title(c: [text(foo.name)])
]),
body(c: [
h1(c: [text(foo.name)])
])
]);
});
}
```
