App Framework Change History

@VERSION@

  • No changes.

3.16.0

Router

  • Fixed issue where Router's hasRoute(url) method did not follow the same semantics as the route dispatching process. Now all registered param handlers will process any named params, giving them a chance to validate and reject a param value. This will make the hasRoute() method an effective way to check whether a router will dispatch to a route handler for a given URL. ([#][])

3.15.0

Model

  • [!] Refactored ModelSync.Local to use a different, more readable storage system. This new storage system is backwards-incompatible with the old storage system. However, the API remains the same and no application code needs to be changed unless you want to maintain the data that is present in localStorage today. ([#1597][])

  • Fixed an issue where history-hash-ie loaded on non-IE browsers. (#1613: @ezequiel)

3.14.1

  • No changes.

3.14.0

  • No changes.

3.13.0

App

  • Added req.aoo which is a reference to the app instance.

Router

  • [!] A router's root path is now enforced as its mount point. Routers with a specified root will only consider paths as matching its route handles if that path is semantically within the router's root path. For example:

      router.set('root', '/app/');
    
      router.hasRoute('/app/');    // => true
      router.hasRoute('/app/foo'); // => true
      router.hasRoute('/bar/');    // => false
    

    This fixed some issues with paths being erroneously considered matching even when they were not semantically within the router's root path. (#1083)

  • [!] The getPath() method now returns the full current path, whereas before it returned the current path relative to the router's root. This also affects req.path which is now the full path as well.

  • [!] Changed Router's dispatching process to take req and res objects instead of creating them inside the _dispatch() method. This refactor also removed the deprecated support for calling res() as an alias for next().

  • Router now accepts route objects through its route() method. These route objects are the same as those specified in a router's routes attribute and what Router uses for its internal storage of its routes. If these route objects contain a regular expression as their path or they contain a regex or regexp property, then they are considered fully-processed. Route objects can also contain any arbitrary metadata which will be preserved. (#1067)

  • Added req.router which is a reference to the router instance.

  • Added req.route which is a reference to the current route object whose callbacks are being dispatched.

  • Calling the dispatch() method will now set req.src to "dispatch".

Model

  • Added ModelSync.Local, an extension which provides a sync() implementation for localStorage that can be mixed into your Models and ModelLists. Examples of it in use can be seen in the YUI TodoMVC example. (#1218)

3.12.0

ModelList

  • Added support for descending sort order via sort({descending: true}). In order to support this, the options passed to sort() are now passed along to the protected _sort() method. (#1004: @rishabhm)

Router

  • Added support for registering route param handler functions or regexps. This allows routes to be defined as string paths while adding validation/formatting to route params, e.g., "/posts:id", and register an id param handler to parse string values into a number and make it available at req.params.id. (#1063)

  • Fixed issue with trying to URL-decode matching path segments that are undefined. Routes defined as regexps (instead of strings) can contain an arbitrary number of captures; when executing the regex during dispatching, its array of matches can contain undefined values. Router will now check that a match is a truthy value before trying to URL-decode it, and coerce undefined values to empty strings. (#964, #1076)

3.11.0

  • No changes.

3.10.3

  • No changes.

3.10.2

Router

  • Router now properly dispatches when using hash-based URLs and calling replace() without arguments; before it would throw an error. [#739]

3.10.1

  • No changes.

3.10.0

Model

  • Fixed: The options object passed to Model's setAttrs() method was being modified. Now a shallow copy of this object is now created so that the _transaction property is added to the copy and not the passed-in object. [#598]

3.9.1

LazyModelList

  • Fixed: Changing an attribute on a revived model did not update the corresponding property on the original object. [#528] [Ryan Grove]

  • Fixed: Revived models didn't have the same clientId as the original object. [#530] [Ryan Grove]

Router

  • Added a more helpful error when a named route callback function doesn't exist. [#513] [Ryan Grove]

3.9.0

App

  • Applied the same changes from CSS Grids to App Transitions to support changes in how Chrome 25 renders word-spacing.

3.8.1

  • No changes.

3.8.0

Router

  • Decode URL-encoded path matches for Router's req.params. [Ticket #2532941]

3.7.3

App

  • Add support for App Transitions in browsers which support native CSS3 transitions without using vendor prefixes. This change means IE10 and Opera get view transitions.

3.7.2

  • No changes.

3.7.1

  • No changes.

3.7.0

App

  • Added App.Content, an App extension that provides pjax-style content fetching and handling, making it seamless to use a mixture of server and client rendered views.

Model

  • Added custom response parsing to ModelSync.REST to make it easy for developers to gain access to the full Y.io() response object. Developers using ModelSync.REST can either assign the parseIOResponse property to false to gain access to the full Y.io() response object in their parse() method, or provide a custom implementation of the parseIOResponse() method.

  • ModelSync.REST's serialize() method now receives the action which the sync() method was invoked with. [Ticket #2532625]

ModelList

  • You may now add models to a ModelList at instantiation time by providing an Object, array of Objects, Model instance, array of Model instances, or another ModelList instance in the items property of the config object passed to ModelList's constructor. This change also applies to LazyModelList.

Router

  • Added support for route-based middleware to Router. The route() method now accepts an arbitrary number of callbacks enabling more reuse of routing code. For people familiar with Express.js' route middleware, this behaves the same. [Ticket #2532620]

View

  • Log a warning when a handler function is not present when a view's events are being attached. [Ticket #2532326] [Jay Shirley, Jeff Pihach]

3.6.0

App

  • Added static property: Y.App.serverRouting, which serves as the default value for the serverRouting attribute of all apps. [Ticket #2532319]

  • Fixed issue with non-collapsing white space between views while transitioning. White space is now fully collapsed and prevents views from jumping after a cross-fade transition. [Ticket #2532298]

  • Organized all CSS classes Y.App uses under a static CLASS_NAMES property.

  • Moved transitioning CSS classname under Y.App.CLASS_NAMES.

Model

  • Added ModelSync.REST, an extension which provides a RESTful XHR sync() implementation that can be mixed into a Model or ModelList subclass.

ModelList

  • Added LazyModelList, a subclass of ModelList that manages a list of plain objects rather than a list of Model instances. This can be more efficient when working with large numbers of items. [Ryan Grove]

  • The add() method now accepts an index option, which can be used to insert the specified model(s) at a specific index in the list. [Greg Hinch]

  • The each() and some() methods now iterate over a copy of the list, so it's safe to remove a model during iteration. [Ticket #2531910]

  • The remove() method now optionally accepts the index of a model to remove (or an array of indices). You no longer need to specify the actual model instance(s), although that's still supported as well.

  • The filter() method now returns an instance of the subclass rather than ModelList itself when called with options.asList set to true on a subclass of ModelList. [Ryan Grove]

  • Fixed an issue where a list that received bubbled events from a model would assume the model was in the list if its id changed, even if the model actually wasn't in the list and was merely bubbling events to the list. [Ticket #2532240]

Router

  • [!] Changed how hash-based paths interact with the URL's real path. The path-like hash fragments are now treated as a continuation of the URL's path when the router has been configured with a root. [Ticket #2532318]

  • Fixed issue when multiple routers are on the page and one router is destroyed the remaining routers would stop dispatching. [Ticket #2532317]

  • Fixed a multi-router issue where creating a router instance after a previous router's save()/replace() method was called would cause in infinite History replace loop. [Ticket #2532340]

  • The req object passed to routes now has a pendingRoutes property that indicates the number of matching routes after the current route in the dispatch chain. [Steven Olmsted]

  • Added a static Y.Router.dispatch() method which provides a mechanism to cause all active router instances to dispatch to their route handlers without needing to change the URL or fire the history:change or hashchange event.

3.5.1

App

  • Added render and update options to the showView() method. [PR #100 Pat Cavit]

Router

  • Added a removeQuery() function that accepts a URL and returns it without a query string (if it had one). [Pat Cavit]

  • Fixed hasRoute() failing to match routes with query params. [Pat Cavit]

  • Fixed bad route regex generation if a placeholder was the last thing in the route. [Pat Cavit]

  • Fixed generated route regexes matching hash/query params when they shouldn't have. [Pat Cavit]

3.5.0

App

  • Initial release.

Model

  • [!] The validate() method is now asynchronous, and is expected to call a callback function on success or failure. Old-style synchronous validate() methods will still work, but are deprecated. [Ticket #2531218]

  • Model now supports ad-hoc attributes, which means it's no longer necessary to subclass Y.Model and declare attributes ahead of time. The following is now perfectly valid, and will result in a model instance with "foo" and "bar" attributes:

        var model = new Y.Model({foo: 'foo', bar: 'bar'});
    
  • load() now fires a load event after the operation completes successfully, or an error event on failure. The load() callback (if provided) will still be called in both cases. [Ticket #2531207]

  • save() now fires a save event after the operation completes successfully, or an error event on failure. The save() callback (if provided) will still be called in both cases. [Ticket #2531207]

  • Options passed to set() and setAttrs() are now correctly merged into the event facade of the change event. [Ticket #2531492]

  • Model's destroy event is now fully preventable (previously it was possible for the model to be deleted even if the destroy event was prevented by a subscriber in the on phase).

ModelList

  • ModelList's model property is now set to Y.Model by default. Since Y.Model now supports ad-hoc attributes, this makes it much easier to create and populate a ModelList without doing any subclassing:

        var list = new Y.ModelList();
    
        list.add([
            {foo: 'bar'},
            {baz: 'quux'}
        ]);
    
  • Added a filter() method that returns a filtered array of models or, optionally, a new ModelList containing the filtered models. [Ticket #2531250]

  • Added a create event that fires when a model is created/updated via the create() method, but before that model has actually been saved and added to the list (and before the add method has fired). [Ticket #2531400]

  • Added a load event that fires when models are loaded. [Ticket #2531399]

  • Models' id attributes (if set) are now used to enforce uniqueness. If you attempt to add a model to the list that has the same id as another model in the list, an error event will be fired and the model will not be added. [Ticket #2531409]

  • The add(), remove() and reset() methods now accept other ModelList instances in addition to models and arrays of models. For example, passing a ModelList to add() will add all the models in that list to this list as well. [Ticket #2531408]

  • ModelList now allows you to add models to the list even if they were instantiated in another window or another YUI sandbox. [Ticket #2531543]

  • ModelList subclasses can now override the protected _compare() method to customize the low-level comparison logic used for sorting. This makes it easy to do things like descending sort, multi-field sorting, etc. See the API docs for details.

  • The reset() method now allows the caller-provided options object to override the src property that's passed on the event facade of the reset event. [Ticket #2531888]

Router (formerly Controller)

  • [!] The Controller class and controller module have been renamed to Router and router respectively. The old names are deprecated, but have been retained as aliases for backwards compatibility. They will be removed in a future version of YUI.

  • [!] The html5, root, and routes properties are now attributes, and routes may be set both during and after init. Code that refers to the old properties, like myController.root and myController.root = '/foo', must be updated to use the attribute syntax instead: myRouter.get('root') and myRouter.set('root', '/foo').

  • [!] The signature for route handlers has changed. Route handlers now receive three arguments: req, res, and next. To preserve backcompat, res is a function that, when executed, calls next(). This behavior is deprecated and will be removed in a future version of YUI, so please update your route handlers to expect next as the third param.

  • "*" can now be used to create a wildcard route that will match any path (previously it was necessary to use a regex to do this). Additionally, paths which contain a "*" (e.g., "/users/*") act as a wildcard matching everything after it.

  • The hasRoute() method now accepts full URLs as well as paths.

  • The hashes used when html5 is false are now root-less; the router's root is removed from the hash before it is set on the URL.

  • When multiple Router instances exist on a page, calling save() in one will now cause matching routes to be dispatched in all routers, rather than only the router that was the source of the change.

  • Added url and src properties to the request object that's passed to route handlers.

  • Made the html5 config attribute writable. This allows you to force a router to use (true) or not use (false) HTML5 history. Please don't set it to false unless you understand the consequences.

  • Added a workaround for a nasty iOS 5 bug that destroys stored references to window.location when the page is restored from the page cache. We already had a workaround in place since this issue is present in desktop Safari as well, but the old workaround no longer does the trick in iOS 5. [Ticket #2531608]

View

  • [!] The container, model, and modelList properties are now attributes. Code that refers to the old properties, like myView.model and myView.model = model, must be updated to use the attribute syntax instead: myView.get('model') and myView.set('model', model).

  • [!] The container attribute now treats string values as CSS selectors. Previously, it assumed string values represented raw HTML. To get the same functionality as the old behavior, pass your HTML string through Y.Node.create() before passing it to container.

  • [!] Destroying a view no longer also destroys the view's container node by default. To destroy a view's container node when destroying the view, pass {remove: true} to the view's destroy() method. [Ticket #2531689]

  • View now supports ad-hoc attributes, which means it's no longer necessary to subclass Y.View and declare attributes ahead of time. The following is now perfectly valid, and will result in a view instance with "foo" and "bar" attributes:

        var view = new Y.View({foo: 'foo', bar: 'bar'});
    
  • Added a containerTemplate property that contains an HTML template used to create a container node when one isn't specified. Defaults to "

    ".
  • When no container node is specified at instantiation time, the container won't be created until it's needed. create() is now only used to create a default container; it's never called when a custom container node is specified.

  • Added a View extension, Y.View.NodeMap, that can be mixed into a View subclass to provide a static getByNode() method that returns the nearest View instance associated with a given Node (similar to Widget.getByNode()).

3.4.1

Controller

  • Added a workaround for an iOS 4 bug that causes the previous URL to be displayed in the location bar after calling save() or replace() with a new URL.

  • Fixed a bug that caused the controller to get stuck in a "dispatching" state if save() was called with no routes defined.

Model

  • The validate() method is now only called when save() is called, rather than on every attribute change. If validation fails, the save operation will be aborted.

3.4.0

  • Initial release.
