The newst new Router for Angular 2 ("Version 3")
1 like952 views
The document discusses the new Component Router for Angular 2, including its support for lazy loading modules, hierarchical routing, guards, and auxiliary routes. The Component Router activates components instead of templates and allows lazy loading of feature modules. It also supports hierarchical routing through nested child routes. Guards can prevent activation or deactivation of components based on authentication checks. Auxiliary routes provide additional placeholder content without interfering with the main router outlet. The presentation includes demos of these features.

The document discusses the new Component Router for Angular 2 and 1.x. The Component Router allows for activating components based on routes, lazy loading of components, hierarchical routing of components with child routes, guards to prevent component activation, and auxiliary routes to add additional components to routes. It provides examples of routing configuration and usage of guards and auxiliary routes. The Component Router is the new routing solution that replaces previous lifecycle hooks and provides additional capabilities over prior routing implementations.Angular 2.0
Angular 2.0Nitin Giri

Angular 2.0 is a major upgrade from Angular 1.X that introduces components instead of controllers, improves performance with more efficient change detection and dependency injection, and adds support for mobile, server-side rendering and standards-based web components. Some key differences between Angular 1 and 2 include a shift to a component-based architecture, removal of scopes and watches, updated directives and dependency injection, and new routing and view encapsulation features. The migration path involves either rewriting the entire application using Angular 2 or upgrading services and components incrementally.What's New in Angular 4 | Angular 4 Features | Angular 4 Changes | Angular Tu...

Angular 2 is a complete rewrite of AngularJS. It is component-based and focuses on better performance. An Angular 2 app is a tree of components. Components are declared using the @Component decorator and the app's routing is configured with the @RouteConfig decorator. The project structure separates the app into modules, components, services and tests. Data binding in Angular 2 allows for unidirectional and two-way binding between the template and component class.Angular 2 - SSD 2016 London

Angular 2 provides more flexibility, speed and simplicity compared to Angular 1. The document outlines Angular 2's new features like the view cache and router. It also discusses migration options like incrementally migrating individual views first before migrating the full app. Developers can migrate top-down or bottom-up, starting with one module and saving the most expensive migrations for last. TypeScript and ES6 bring strong typing and modularity to Angular 2. Bindings in Angular 2 are to properties rather than attributes for simplicity and tooling support. Lazy loading allows dividing code into modules loaded on demand.Migrating From Angular 1.x to Angular 2+

Routing in Angular allows directing users to different pages/components based on their navigation choices. It defines routes for pages by creating components and linking them in the routes configuration. Components can link to routes using routerLink and navigate between them in code using the Router service. Route guards prevent navigation under certain conditions. Lazy loading allows splitting the app into smaller modules to improve performance. Code is cleaned up by exporting all imports from a single index file.An Intro to Angular 2

Angular is a platform for building mobile and desktop web applications. It is no longer just a framework. Angular 2 offers improvements such as faster performance, modularity, support for modern browsers, and reactive programming using RxJS. Key parts of Angular include templates, directives, data binding, components, services, modules, and dependency injection. Features like Ahead-of-Time compilation and services improve app performance and reusability. TypeScript adds benefits like static typing and class-based programming.Angular 2... so can I use it now??

Angular 2 is now in release candidate and can be used for new projects, though Angular 1 will still be supported for the next 1.5-2 years. There are two main approaches to upgrading an existing Angular 1 app to Angular 2: big bang, where the entire app is rewritten at once in Angular 2, or incremental, where individual components are upgraded one by one. Components and directives are now unified under the component model in Angular 2. TypeScript is recommended for Angular 2 development but not required, as JavaScript can also be used.An afternoon with angular 2
