The Missing Introduction to Angular 2 and Modern Design Patterns

Introduction to Angular

Angular (aka Angular 2) is a new framework completely rewritten from the ground up, replacing the famous AngularJS framework (aka Angular 1.x).

More that just a framework, Angular should now be considered as a whole platform which comes with a complete set of tools, like its own CLI, debug utilities or performance tools.

1 Background (page 2)

Today's system requirement

  • large number of request
  • huge amount of data
  • quick response time
  • (almost) 100% uptime

(page 3) If we compare the number of Internet users in the past decades with the number of users of the two afore mentioned websites, we can see that they now handle as much traffic as the entire Internet used to.

What forces layout/reflow. The comprehensive list.

What forces layout / reflow

All of the below properties or methods, when requested/called in JavaScript, will trigger the browser to synchronously calculate the style and layout*. This is also called reflow or layout thrashing, and is common performance bottleneck.

Generally, all APIs that synchronously provide layout metrics will trigger forced reflow / layout. Read on for additional cases and details.

Element APIs

Getting box metrics
  • elem.offsetLeft, elem.offsetTop, elem.offsetWidth, elem.offsetHeight, elem.offsetParent
