Domain Modeling Made Functional with Scott WLASCHIN- Online Workshop: 07-10-14-17-24-28 november 2022, 01 december 2022 (2 hours session each day)

Overview

Online Workshop in Live Streaming with Scott Wlaschin.
The orginal 2-day workshop will be split over 8 two hours sessions : 07-10-14-17-24-28 november 2022, 01 december 2022, from 17.30 to 19.30 pm (CEST) each day.

Functional programming and domain-driven design might not seem to be a good match, but in fact functional programming can be an excellent approach to designing decoupled,reusable systems with a rich domain model. This workshop will show you why.

This will be a hands-on workshop designed for beginners in functional programming.

We’ll do lots of exercises and build some small projects that take us all the way from high-level design to low-level implementation.

Workshop format:

Each session is two hours long, with a space of three days to allow attendees to work on each part to easily integrate it.

Each session starts at 17:30 CEST to allow people to attend it after a work day.

Prerequisites

We will be using F# as our development language. No experience with F# needed.

Instructions on how to install F# and configure your workstation will be provided before the workshop.

The workshop will be held inEnglish, so understanding English is mandatory.

Dates and Timing: The workshop will take place online and in live streaming on 07-10-14-17-24-28 november 2022, 01 december 2022, from 17.30  to 19.30 pm (CEST) each day.

To attend this workshop, you’ll need a stable internet connection (20MB in download). It is advise to check your connection’s speed.

Maximum number of attendees: 20 participants.

 

Online Workshop – How does it work

The workshop will happen online and in live streaming: the trainer and all other participants will be in a video conference. You’ll be interacting and working together in real-time thanks to a variety of tools you’ll have at your disposal.

The workshop will keep its highly interactive and hands-on spirit despite being online.
This is why we require that all participants keep their webcam on for the whole duration of the workshop: this will enhance the quality of the communication and of the workshop as a whole.
You won’t be sitting at your desk watching slides and videos, and you’ll be engaged in real-time activities for the majority of the time… as if we were in a real classroom!

 

This is what you will learn

  • The concepts of functional programming
  • How to represent the nouns and verbs of a domain using types and functions
  • How to decouple the pure domain logic from the outside world
  • How to ensure that constraints and business rules are captured in the design
  • How to represent state transitions in the domain model
  • How to build a business workflow from smaller components
  • How to handle errors as part of the domain

By the end of the workshop, you’ll know how to build working solutions with rich domain models, using only functional programming techniques.
