This will be a hands-on workshop designed for beginners in functional programming. We'll do lots of domain modeling exercises starting with some simple models and then enhancing them with constraints, state machines, error handling, commands and events, and so on.

The core concepts of functional programming and how they can be applied to Domain Driven Design

How to represent the nouns and verbs of a domain (e.g. the ubiquitous language) using types.

Why representing the domain model using types is better than UML or other documentation (hint: it can never get out of sync)

How to capture constraints and business rules in the domain model itself instead of being buried in the implementation

How to treat errors as a part of the domain

How to build a complete business workflow from smaller components using composition

How to design a functional architecture with bounded contexts, validation, I/O and on.

At the end of the workshop you'll know how to accurately represent a rich domain using some simple code which can then be used as the starting point for an implementation

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.

We believe in a world of work where people can find their true self and achieve their full potential. This not only makes individuals more satisfied and happier, it also makes companies more successful. 
 
Based on this conviction, New Work SE aligns its brands, products and services around its vision – For a better working life. We’re already seeing a paradigm shift in terms of what we call ‘work’. Demographic change is exacerbating the shortage of skilled workers, in turn shifting power away from employers and over to employees.

Digitalisation is not only revolutionising entire industries, it also enables people to work wherever and whenever they want or need to. And younger generations, in particular, are eschewing long-standing values in favour of more modern ones with a clearer focus on a positive work-life balance.
 
All of these aspects are already driving radical change on the labour market. All of the activities undertaken by each New Work Group brand aim to help shape the future of work and gear it more towards people, while assisting companies in the pursuit of success by enabling employees to do what they really, really want to do.
