Upcoming features that will make Angular 2 a powerful option in a near future.

Last Tuesday I enjoyed a talk of Miško Hevery about Angular2 thanks to guys of AngularBeers. It was a talk about what is coming with Angular 2 and the key point with which we have to stay is that Angluar leave the concept of frontend framework to become a full a platform.

But, apart from this, I would like to remark a couple of things that will make Angular 2 a powerful option in a near future.

Offline compile

What does this means? Templates have been one of the places where mistakes are made since Angular 1. Even if we introduce TypeScript or lint tools, we couldn't be able to detect mistakes in templates until they are evaluated at the runtime. Until now Angular 1.X compiles the templates each time they should be rendered.

With Angular 2 (without offline compile) the templates are compiled only once. But with offline compiling the templates are compiled on build time to JavaScript so it will be never compiled in the browser. The benefits we obtain here is that it enables us to statically type-check our templates with TypeScript, which is awesome, in addition to skipping the runtime compilation and smaller library size.

Angular Universal

Universal (isomorphic) JavaScript support for Angular 2.

With Angular Universal, we can run Angular 2 in the server side and this gives us some advantages:

  1. Better Perceived Performance: The users will instantly see a server-rendered view which greatly improves perceived performance and the overall user experience.
  2. Optimized for Search Engines: Server-side pre-rendering is a reliable way to ensure that all search engines can access your content.
  3. Site Preview: Ensure that Facebook, Twitter, and all other social media apps correctly display a preview image of your app. (I deal with this problem before and is a pain in the ass)
