It allows the customer to create collections of tabs and share those collections in workspaces creating an easy, cataloged, and specialized user experience for each workspace. XYZ is a product that helps you to organize your browser tabs and bookmarks to facilitate the interaction with the tabs you open the most. Let’s quickly define a domain and let’s model its main components as code. I am saying this because, in Golang, there’s no way to prevent the creation of a type in an invalid state. Or coupling the validation with the type that protects the invariants.Įach way has its bonus and malus it is on us to evaluate those options and pick the best for our scenario,Ĭonsidering the programming language to define those rules too. There are many ways to achieve this goal: adding a validation HTTP middleware, creating a function that validates the CLI input, The idea around the always valid state is that a type shouldn’t be created when it is not compliant with the invariants of its context. I would start from the concept of the always valid state because it is going to influence the way of writing code. The patterns I am going to cover in this article are the most known and used:īefore describing one by one all the patterns derived from the DDD literature, I want to take a different direction. The tactical patterns are well known in communities of languages such as PHP, Java, and C# because the resources available today about DDD patterns are mostly in OOP,īut this doesn’t mean that it is hard or wrong to adapt those concepts in languages that use different paradigms.

The end goal of applying those patterns is to model the code in a simple but expressive and safe way. The tactical design describes a group of patterns to use to shape as code the invariants and models defined in a domain analysis that is often driven by the strategic design. Tactical designīefore starting, I think it is essential to define what tactical design is. So I decided to address some of those questions, and I am going to explain more widely my vision about Golang and DDD describing some code patterns I use and trade-offs I always consider.

#GOLANG DOMAIN DRIVEN DESIGN HOW TO#

Most of the questions I received privately were about how to write an entire Golang project (or code in general) using DDD tactical patterns.

In the past few weeks, I received a lot of private and public questions about the first article of the Golang and Domain-Driven Design series I wrote.
