Installation

1)

brew install nginx
sudo cp /usr/local/Cellar/nginx/1.8.0/homebrew.mxcl.nginx.plist /Library/LaunchAgents

2)

Replace /usr/local/etc/nginx/nginx.conf with the nginx.conf in this gist. I'm using port 5000 for my current project. Obviously, change server_name as well, and probably the name of its access log.

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

const daggy = require('daggy');
const {range} = require('ramda');

// type to hold an index and the array
const Pointer = daggy.tagged('i', 'a')

// Comonad instance
Pointer.prototype.extract = function() { return this.a[this.i] }
