"For services to the PureScript Community, Gary Burgess!"

You've done it, Gary. Moore, Lineker, Coleman, and now Burgess. All the work was worth it. The halls erupted with praise. Children dressed as Space Ghost, teens with "I only get high on Halogen" t-shirts, a giant banner held aloft with the message, "Tuple @garyb me". Through the noise of the crowds and Phil's uninterpretable Northern accent, he barely managed to hear his theme tu-

BZZP. BZZP.

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
