This is my main.js file in a Durandal project.
What I'm trying to do is set things up so that the name 'upload-item' resolves to either 'upload-item' or 'upload-item-prehtml5' depending on whether File
is defined.
requirejs.config({
paths: {
'text': '../lib/require/text',
'durandal': '../lib/durandal/js',
'plugins': '../lib/durandal/js/plugins',
'transitions': '../lib/durandal/js/transitions',
'knockout': '../lib/knockout/knockout-2.3.0',
'bootstrap': '../lib/bootstrap/js/bootstrap',
'jquery': '../lib/jquery/jquery-1.9.1.min',
'jquery-ui': '../lib/jquery-ui/jquery-ui-1.10.4.custom/js/jquery-ui-1.10.4.custom.min',
'moment': '../lib/moment/moment',
'knockout-jqueryui': '../lib/knockout/knockout-jqueryui.min',
'file-size-formatting': '../lib/wone/file-size-formatting'
},
shim: {
'bootstrap': {
deps: ['jquery'],
exports: 'jQuery'
}
}
});
define(['durandal/system', 'durandal/app', 'durandal/viewLocator'], function (system, app, viewLocator) {
//>>excludeStart("build", true);
system.debug(true);
//>>excludeEnd("build");
var filetype = typeof(File);
if (filetype == 'undefined') {
//apply pre-html5 fixups
require.config({
map: {
'*': {
'upload-item': 'upload-item-prehtml5'
}
}
});
}
app.title = 'Jumbo File Transfer';
//specify which plugins to install and their configuration
app.configurePlugins({
router: true,
dialog: true,
widget: {
kinds: ['expander']
}
});
app.start().then(function () {
//Replace 'viewmodels' in the moduleId with 'views' to locate the view.
//Look for partial views in a 'views' folder in the root.
viewLocator.useConvention();
//Show the app by setting the root view model for our application.
app.setRoot('shell');
});
});
Testing on IE8 shows that the call to require.config occurs and the mapping is added, but it doesn't seem to have the effect I expected: upload-item.js and upload-item.html are loaded when I expected upload-item-prehtml5.js and upload-item-prehtml5.html to be loaded.
If this is the wrong way to go about this, then what is the right way to perform this kind of conditional resolution?
