José Valim explores the classical Gang of Four design patterns and analyzes their applicability and deconstruction from Elixir's perspective.

✨This keynote talk was recorded at ElixirConf EU 2024. If you're curious about our upcoming event, check elixirconf.eu ✨ In this talk, José Valim explores the classical Gang of Four (Design Patterns) book and answer the question if they are applicable to Elixir programs or not. He also talks about objects, how we can understand and deconstruct them from Elixir’s perspective, and how such deconstruction impacts the design of large systems. Let's keep in touch!

What people say. Highly recommended as an insightful exploration of how object-oriented design patterns translate to functional programming in Elixir.

On “Once Again: LiveView vs. LiveVue / LiveSvelte / Inertia.js vs. Split Frontend<>Backend”

Tight coupling is not a con by itself. If there was a consequence as a result of coupling you can say its a con. See jose’s presentation minute18: link to this video Decoupling brings complexity

On “Learning resources for new programmer”

…another, I can comfortably argue that FP is simpler than OO. OO is about the bundling of multiple concepts into a single entity: inheritance, polymorphism, state, behaviour, etc. You learn all of those things at once and then you learn how to work around the bundling. FP has fewer concepts that you compose, and I gave a whole talk about it here: link to this video Similarly, immutability is easier to grasp than mutability, because immutability is ultimately about focusing on the data, while mutability is data changing over time (so you have one added dimension there). And if someone is coming from mathematics, the concepts of immutability, functions, and recursion, are going to feel way more natural…

On “I am completely lost when it comes to *which* control flow pattern to use. Have best practices in this regard been jotted down somewhere?”

The creator of elixir also did a talk on design patterns last week. [video

On “Is there any literature teaching programming principles in Elixir? or is it all C and python?”

Slightly related, a great talk that clarified a ton in my head: link to this video
