Get the details to connect to your Nexus-managed npm repository

Note: Nexus group repositories (good example in this StackOverflow question) are out of this tutorial's scope. In any case, deployment to group repositories is currently still an open issue for Nexus 3 (and not intended ever to be implemented in Nexus 2). Thus, it is assumed that we'll push & pull to/from the same repository, and ignore the idea of groups hereon in.

1. Ask your sysadmin for a username & password allowing you to log into your organistation's Nexus Repository Manager.

2. Test the login credentials on the Nexus Repository manager at: http://localhost:8081/nexus/#view-repositories (localhost in our case is replaced by a static IP, and can only be connected to over VPN). If your organisation requires a VPN to connect to it, connect to that VPN before proceeding with this tutori

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
