Installing Babel

The following are a few important npm packages.

Core Babel and access to Babel:

• babel-core: the core compilation machinery and plugin infrastructure for Babel. You will rarely need to install this package, because other packages such as babel-cli have it as a dependency, meaning that it will be automatically installed when they are installed.

• babel-cli: a command line interface to Babel. It includes the following commands:

• babel-doctor detects common problems with your Babel installation.

Angular2 + JSPM cheat sheet

First time setup

• install jspm beta: npm install -g jspm@beta
• set up your project: jspm init
• install dependencies: jspm install angular2 reflect-metadata zone.js es6-shim

This will create a jspm_packages folder, and a config.js file.

Open the config.js file - this file manages options for the System.js loader - tweak it as appropriate

Screencapture and animated gifs

I say "animated gif" but in reality I think it's irresponsible to be serving "real" GIF files to people now. You should be serving gfy's, gifv's, webm, mp4s, whatever. They're a fraction of the filesize making it easier for you to deliver high fidelity, full color animation very quickly, especially on bad mobile connections. (But I suppose if you're just doing this for small audiences (like bug reporting), then LICEcap is a good solution).

Capturing (Easy)

1. Launch quicktime player
2. do Screen recording

Architecture in Elm

This document is a collection of concepts and strategies to make large Elm projects modular and extensible.

We will start by thinking about the structure of signals in our program. Broadly speaking, your application state should live in one big foldp. You will probably merge a bunch of input signals into a single stream of updates. This sounds a bit crazy at first, but it is in the same ballpark as Om or Facebook's Flux. There are a couple major benefits to having a centralized home for your application state:

1. There is a single source of truth. Traditional approaches force you to write a decent amount of custom and error prone code to synchronize state between many different stateful components. (The state of this widget needs to be synced with the application state, which needs to be synced with some other widget, etc.) By placing all of your state in one location, you eliminate an entire class of bugs in which two components get into inconsistent states. We also think yo
