This is a big change. @matsko also deserves much of the credit for the implementation. Previously, `ComponentInstruction`s held all the state for async components. Now, we introduce several subclasses for `Instruction` to describe each type of navigation. BREAKING CHANGE: Redirects now use the Link DSL syntax. Before: ``` @RouteConfig([ { path: '/foo', redirectTo: '/bar' }, { path: '/bar', component: BarCmp } ]) ``` After: ``` @RouteConfig([ { path: '/foo', redirectTo: ['Bar'] }, { path: '/bar', component: BarCmp, name: 'Bar' } ]) ``` BREAKING CHANGE: This also introduces `useAsDefault` in the RouteConfig, which makes cases like lazy-loading and encapsulating large routes with sub-routes easier. Previously, you could use `redirectTo` like this to expand a URL like `/tab` to `/tab/posts`: @RouteConfig([ { path: '/tab', redirectTo: '/tab/users' } { path: '/tab', component: TabsCmp, name: 'Tab' } ]) AppCmp { ... } Now the recommended way to handle this is case is to use `useAsDefault` like so: ``` @RouteConfig([ { path: '/tab', component: TabsCmp, name: 'Tab' } ]) AppCmp { ... } @RouteConfig([ { path: '/posts', component: PostsCmp, useAsDefault: true, name: 'Posts' }, { path: '/users', component: UsersCmp, name: 'Users' } ]) TabsCmp { ... } ``` In the above example, you can write just `['/Tab']` and the route `Users` is automatically selected as a child route.
