The introduction to Reactive Programming you've been missing

Introduction

At DICOM Grid, we recently made the decision to use Haskell for some of our newer projects, mostly small, independent web services. This isn't the first time I've had the opportunity to use Haskell at work - I had previously used Haskell to write tools to automate some processes like generation of documentation for TypeScript code - but this is the first time we will be deploying Haskell code into production.

Over the past few months, I have been working on two Haskell services:

A reimplementation of an existing socket.io service, previously written for NodeJS using TypeScript.
A new service, which would interact with third-party components using standard data formats from the medical industry.

I will write here mostly about the first project, since it is a self-contained project which provides a good example of the power of Haskell. Moreover, the proces

	#!/bin/bash
	AUTHOR=$(git config user.name)
	DATE=$(date +%F)
	git log --no-merges --format="%cd" --date=short --no-merges --author="$AUTHOR" --all \| sort -u -r \| while read DATE ; do
	if [ $NEXT != "" ]
	then
	echo
	echo [$NEXT]
	fi
	GIT_PAGER=cat git log --no-merges --format=" %s" --since=$DATE --until=$NEXT --author="$AUTHOR" --all

	!function() {
	var d3 = {
	version: "3.4.11"
	};
	if (!Date.now) Date.now = function() {
	return +new Date();
	};
	var d3_arraySlice = [].slice, d3_array = function(list) {
	return d3_arraySlice.call(list);
	};
