Bring web standards to native platform

samurai-native enables you to build native apps using web technologies (HTML/CSS) based on its own Web-Core. Support iOS now, Android later.

Check out demo at samurai-examples/dribbble and samurai-examples/movie.

Native Components

You can use the native components such as UICollectionView and UICollectionViewCell on iOS. This gives your app a consistent look and feel with the rest of the platform ecosystem, and keeps the quality bar high. These components are easily incorporated into your app using <UICollectionView/> and <UICollectionViewCell/> directly.

<html>

	<body>
		
		<UICollectionView class="list" is-vertical>
			<UICollectionViewCell is-static is-row>
				...
			</UICollectionViewCell>
		</UICollectionView>

	</body>
	
</html>

HTML Components

You can use the standard HTML tags such as div and img on iOS. This gives you ability to define your user interface using a hybrid way.

<html>

	<body>

		<UICollectionViewCell is-static is-row>
			<div class="profile-wrapper">
				<div class="profile-attribution">
					<div class="profile-segment no-wrap">
						<div class="segment-wrapper">
							<span class="segment-count">10,875</span>
							<span class="segment-suffix">Followers</span>
						</div>
					</div>
					<div class="profile-segment no-wrap">
						<div class="segment-wrapper">
							<span class="segment-count">199</span>
							<span class="segment-suffix">Followers</span>
						</div>
					</div>
				</div>
			</div>
		</UICollectionViewCell>

	</body>
	
</html>

CSS Fluid layout

We brought the css layout model from the web to samurai-native, css layout makes it simple to build the most common UI layouts, such as stacked and nested boxes with margin and padding. samurai-native also supports common web styles, such as font-weight and border-radius, and you can extend your style in SamuraiHtmlRenderStyle class.

(TODO: Flex-Box)

<html>

	<head>
		
		<link rel="stylesheet" type="text/css" href="../css/normalize.css"/>
		<link rel="stylesheet" type="text/css" href="../css/main.css"/>
		
	</head>
	
</html>

<html>

	<body>
	
		<p style="color: red;">
			Hello, world!
		</p>
		
	</body>

</html>

<html>

	<body>
	
		<div class="tab-bar">
			<div class="tab">Popular</div>
			<div class="tab">Debuts</div>
			<div class="tab">Everyone</div>
		</div>

		<style>
		
			.tab-bar {
				display: block;
				width: 100%;
				height: 34px;
				background-color: #e5508c;
				/* box-shadow: 0px 0.5px 0.5px black; */
				z-index: 2;
			}
		
			.tab {
				float: left;
				display: block;
				width: 33.33%;
				height: 34px;
				font-size: 14px;
				line-height: 34px;
				color: #fff 0.75;
				text-align: center;
				font-weight: normal;
			}
			
			...
			
		</style>
		
	</body>

</html>

Easy to Integration

@implementation MyViewController

- (void)viewDidLoad
{
	[self loadViewTemplate:@"/www/html/dribbble-index.html"];
//	[self loadViewTemplate:@"http://localhost:8000/html/dribbble-index.html"];
}

- (void)dealloc
{
	[self unloadViewTemplate];
}

- (void)onTemplateLoading {}
- (void)onTemplateLoaded {}
- (void)onTemplateFailed {}
- (void)onTemplateCancelled {}

@end

Signal Handling

samurai-native provide a high level event system called Signal, you can interact with HTML page through signal system.

<div onclick="signal('switch-tab1')">
	Popular
</div>

@implementation MyViewController

handleSignal( switch_tab1 )
{
	[self something];
}

@end

Data Binding

samurai-native provide a efficient way to binding native objects to HTML page in single way through DOM's name property.

<html>
	<body>
	
		...		
	
		<div name="author">
			<img name="avatar"/>
			<div>
				<div name="title"/>
				<div>by <span name="name"/></div>
			</div>
		</div>
		
		...
		
	</body>
</html>

@implementation MyViewController

...

- (void)reloadData
{
	self[@"author"] = @{			  
		@"avatar" : "xxx.jpg",
		@"title"  : @"Hello",
		@"name"   : @"World"
	};
}

@end

Extensibility

samurai-native is designed to be easily extended with custom native components, that means you can reuse anything you've already built, and can import and use your favorite native components.

@implementation UILabel(Html)

- (void)html_applyDom:(SamuraiHtmlDomNode *)dom
{
	[super html_applyDom:dom];

	self.text = [dom computeInnerText];
}

- (void)html_applyStyle:(SamuraiHtmlRenderStyle *)style
{
	[super html_applyStyle:style];

	self.font = [style computeFont:self.font];
	self.textColor = [style computeColor:self.textColor];
	self.textAlignment = [style computeTextAlignment:self.textAlignment];
	self.baselineAdjustment = [style computeBaselineAdjustment:self.baselineAdjustment];
	self.lineBreakMode = [style computeLineBreakMode:self.lineBreakMode];
	self.numberOfLines = 0;
	
	...
}

@end

Live reload
