Features

There is no particular requirement on the position in the hierarchy of the

Notes: All the examples below are only tested on Vue.js 1.0 (above).

Notes: The examples below use ES6 so it's recommended to use browserify or webpack to easily integrate babel.

when or where can we use this.$el

When you need to access DOM attribute, be careful with the lifecycle. Vue.js has a few useful lifecycle hooks.

Let's say we want to scroll our component to the bottom (imagine it's a long list with overflow-y: auto) once it's instantiate.

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

Setup modern.ie vagrant boxes

Since modern.ie released vagrant boxes, it' no longer necessary to manually import the ova file to virtualbox, as mentioned here.

However, the guys at modern.ie didn't configured the box to work with WinRM. This how-to addresses that, presenting steps to proper repackage these boxes, adding WinRM support. Additionally configures chocolatey package manager and puppet provisioner.
