🔌 Hexagonal architecture explained

1. Independence: Your business logic doesn't know whether you use MongoDB or PostgreSQL.
2. Testability: You can test your app's core without lifting servers or databases.

Today's #genuary prompt seemed perfect for a Truchet tiling image, where the curve perfectly fills the space.

A hexagon filled with wandering black-and-white curves and circles filling the space.

DevX → BotX: Khi bot lấy quyền viết mã, cần duy trì kiểm thử liên tục, vòng lặp nhanh (unit test thường xuyên), loại bỏ test giả tích hợp, lint kiến trúc theo mẫu hexagonal, dùng abstraction cho IO, giới hạn import, và duy trì coverage hợp lý. Những nguyên tắc này giúp bot tạo mã duy trì, tránh spaghetti. #DevX #BotX #Testing #Architecture #Hexagonal #CI #Automation #PhátTriển #Bot #KiểmThử #KiếnTrúc

For anyone interested in #ecology, specifically #FireEcology, here is a little #simulation I created several years ago...

It is also a good example of using a #hexagonal grid on a #web page.

Merry Christmas, to those who celebrate!

As a gift, the recording of my talk on "Testable Architecture" that I recently gave at the Calgary Software Crafters meetup is now available!

Business logic belongs to developers. Glue code does not ✊

1) Business logic carries intent, rules, and knowledge. Only human judgment and design matter.

2) The infrastructure layer is largely made of:
- repetitive adapter code,
- framework-specific wiring,
- predictable mappings and configuration.

👉 Is it realistic to consider infrastructure as something that should be generated, rather than written and maintained by hand?

I’m curious to hear your perspective.

👨‍💻🚀 So, someone decided to sprinkle some -source fairy dust on their and Next.js starter kit, and it's apparently production-ready with a side of "hexagonal architecture" 🍕. Clearly, the world was eagerly awaiting another as if it's the 8th wonder of the world. 🙄

#KnowledgeBit: A #Hexagonal #Number is a figurate number that represents the number of distinct dots in a pattern of dots.

The pattern consists of the outlines of regular hexagons with sides up to n dots, when the hexagons are overlaid so that they share one vertex.

For my next #testing course, I've devised my most evil kata yet :

git.dmerej.info/dmerej/kata-pe

It has a "clean" architecture and 100% test coverage, yet the main route always return 500 ...

I'm going to use it to teach about the dangers of mocks, tests after, and not properly understanding #hexagonal architecture 😈

#ITByte: The #Hexagonal #Architecture, or ports and adapters architecture, is an architectural pattern used in software design.

It aims at creating loosely coupled application components that can be easily connected to their software environment by means of ports and adapters. This makes components exchangeable at any level and facilitates test automation.

I think I understand Hexagonal Architecture now, after writing a few test apps. It really shines when changing adapters (implementations) and at the moment I'm just sold at it. scotthannen.org/blog/2024/07... #development #architecture #hexagonal

xUnit Test Patterns: Contract Test — zalas.pl/contract-test/

Contract Tests are examples that describe the behaviour of an abstraction by expressing what cannot be encoded in the type system. These are typically helpful in testing adapters as defined in the Ports & Adapters architecture.

Examples in , but the pattern is universal.

Contract Test Describes the Contract and exercises the System Under Test (SUT). The Contract Test abstracts implementation detail behind intention revealing names. The concrete test case that implements the Contract Test provides implementation details.

#Hexagonal #Architecture folks: how do you deal with the fact that a repository implementation needs access to aggregate implementation classes to materialize them, incl. referenced value objects etc. That makes all those types end up in a secondary port, doesn't it? What's left for the application core then?

Also a suggestion for companies with stands at #FOSDEM ... Funky shaped stickers area all well and good but if you make them smaller and "tilable" then people are more likely to include yours on their laptop. Also probably less wasteful in the production line ... Here's a talk on the subject I saw in 2015. For some reason there aren't many this shape any more #sticker #hexagon #hexagonal
