  • In other words, by having a different implementation of the renderer we can use the same AoT compiled component and render it without any changes in the code.
  • The Angular template compiler receives as an input a component and a context (we can think of the context as a position in the component tree) and produces the following files: – – is a placeholder for the file’s name.
  • If we want to emit TypeScript as output of the AoT compilation process we must make sure we access only public fields in the templates of our components.
  • Since TypeScript has access modifiers, and enforces access only to public properties outside the inheritance chain, inside the internal component we cannot access any private properties part of the context object, so both: – – will throw a compile time error in the generated .
  • For this component, the Angular compiler will generate two classes: – – will be responsible for rendering the template of and also, performing change detection.

  • It was 2016 when Vue.js rose to fame and gained so much traction that it’s now seen as an alternative for even well established JavaScript libraries, such as Angular and React.
  • Since Angular belongs to search engine giant Google and React comes from social media behemoth Facebook, developers still trust and use those libraries more than Vue.js.
  • This blog attempts to shed light on why there is a growing belief among developers that Vue.js is set to become the top JavaScript library, leaving behind Angular and React.
  • The reason many developers are turning to Vue is that it addresses the issues of React and Angular.
  • But, one must not forget that Angular and React are still very big names in the JavaScript world, whereas Vue has just begun to rise.

  • It happens that angular will make a promise on bootstrap, create a Page synchronously, chain a promise that will create the Page UI, the promise is resolved but the callbacks chained happen on the next tick on the main loop, so iOS layouts the main Window capturing a white page….
  • What happens next is the promise ticks, creates UI but iOS wouldn’t fire a next layout, delaying the ListView and its cell generation until the launch-screen to home component animation is played.
  • Here is how it looks, see the white page blinking between the {N} logo and the main-page: – – With the nativescript-angular v3.4 we will drain the microtasks in the nativescript-zone in the UIViewController’s viewWillAppear, having angular create the whole UI synchronously.
  • iOS will happily render it all before the launch-screen to home component animation is played leading to the following times: – – You have probably noted the big chunk of CSS parsing actually moved into the vendor, it will be captured in the android snapshot now.
  • But the transition from it to the home component will fade nicely this time.
