Before Famo.us completely changed their architecture I was developing some Apps using Famo.us, RequireJS, EJS Templates, Node and some other stuff.
But now when I come to replace the old Famo.us architecture with the new Famo.us 'Engine' I am getting errors - which tells me the architecture is wrong for the new approach - so wondered if you guys can help me.
Background
- Server is Node.js, Express 4 and some other stuff
- Client will be Famo.us, EJS Templates and some other stuff
The current approach is that the '/' Router calls an 'ejs' template.
index.ejs:
<!DOCTYPE HTML>
<html>
<head>
<title></title>
<meta name="viewport" content="width=device-width, initial-scale=1, minimum-scale=1.0, maximum-scale=1.0, minimal-ui" />
<meta name="mobile-web-app-capable" content="yes" />
<meta name="apple-mobile-web-app-capable" content="yes" />
<meta name="apple-mobile-web-app-status-bar-style" content="black" />
<link rel="stylesheet" type="text/css" href="/css/famous.css" />
<link rel="stylesheet" type="text/css" href="/css/style.css" />
</head>
<body>
<script data-main="/js/webmain.js" src="/js/vendor/requirejs/require.js"></script>
</body>
</html>
This worked fine with old Famo.us architecture...and would call the webmain.js script using RequireJS.
webmain.js:
/* globals require */
require.config({
baseUrl: "js",
nodeRequire: require,
paths: {
"famous": "vendor/famous",
"famous-flex": "vendor/famous-flex/src",
json2: "vendor/json2",
"requirejs": "vendor/requirejs/require",
"socketcluster": "vendor/socketcluster",
"ua-parser" : "vendor/ua-parser.min",
"uuid": "vendor/uuid"
}
});
require(["platform"]);
The 'platform.js' script would contain the following:
define('platform', function(require, exports, module) {
'use strict';
var Engine = require("famous/core/Engine");
var contentContext = Engine.createContext();
var Widget = require('app/widgets/DefaultWidget');
var mainView = new Widget();
var contextSize = [undefined, undefined];
contentContext.setPerspective(1);
Engine.nextTick(function() {
contextSize = contentContext.getSize();
mainView.setOptions({size: [contextSize[0], contextSize[1]]});
contentContext.add(mainView);
});
contentContext.on('resize', function(e) {
contextSize = contentContext.getSize();
if (mainView) mainView.setOptions({size: [contextSize[0]*1, contextSize[1]*1]});
}.bind(this));
});
But the new version of Famo.us will not work using this approach and I wanted to ask your thoughts as to why, or if there was another way they have not mentioned?
I have updated the Famou.us source code in 'vendor/famous' to use the 'Famo.us Engine' code from github. If I replace the old Famo.us code in the 'platform.js' script with new Famo.us code - like this:
define('platform', function(require, exports, module) {
'use strict';
var FamousEngine = require('famous/core/FamousEngine');
var DOMElement = require('famous/dom-renderables/DOMElement');
FamousEngine.init();
var scene = FamousEngine.createScene();
var node = scene.addChild();
var domEl = new DOMElement(node, {
content: 'Hello World',
properties: {
fontFamily: 'Arial'
}
});
});
I get the following errors:
Uncaught Error: Module name "Clock" has not been loaded yet for context: _. Use require([]) require.js:8
Uncaught Error: Module name "../utilities/CallbackStore" has not been loaded yet for context: _. Use require([]) require.js:8
Uncaught TypeError: Cannot read property 'init' of undefined platform.js:28
I guess I am trying to understand, when the RequireJS skeleton is pretty much the same, why it doesn't work? Why Famo.us is undefined, and why the new Famo.us architecture can break so much - and what the 'new' way of integrating famo.us would be?
I have asked questions on their 'slack' IRC but it doesn't seem to be a way to get answers and a really poor 'help'.
Any help would be greatly appreciated as I am really stuck from moving forward at the moment.
Thanks again.
Famo.us version 0.3.5 and earlier used RequireJS using AMD.
The new version 0.5.0+ uses the node.js flavor of CommonJS and uses
