Derby layout with persistent header
In your derby-app:
var derby = require('derby');
// Just require the package
require('derby-header');
var app = derby.createApp('twopages', __filename);So, you have the layout:
<html>
<head>
<!-- ....... -->
</head>
<body>
<div id=header>
<view is="Header"/>
</div>
<div id=body>
<view is="Body"/>
</div>
</body>
</html>All html in the #header-element is persistent and doesn't erase when app-routes are changing. You also can use components inside the #header.
The package is created for client rendering. So, if you want to subscribe to some data for your header use component "create"-function. For example:
in my index.html:
<!-- classic body layout-->
<Body:>
<view is="{{$render.ns}}"/>
<Header:>
<view is="header"/>
"header"-component example:
module.exports = Header;
function Header(){}
Header.prototype.view = __dirname;
Header.prototype.style = __dirname;
Header.prototype.name = header;
Header.prototype.init = function(model){
}
Header.prototype.create = function(model){
// Create a childModel with 'global' context
// if we use regular root-model the subscription
// is unsubscribed after url is changed
this.globalModel = model.root.context('global');
var items = this.globalModel.query('items', {});
items.subscribe(function(err){
items.ref(model.path('items'));
model.set('loaded', true);
});
}
Header.prototype.destroy = function(){
this.globalModel.unload();
}index.html
<index:>
{{if loaded}}
