The article argues against premature abstraction, showing real examples of unnecessarily complex code that could be replaced with straightforward solutions. Key principles include: abstract only what changes frequently, wait for three use cases before creating abstractions, avoid interfaces with single implementations, and prioritize readability over architectural sophistication. Simple, boring code that solves actual problems scales better than over-architected solutions designed for hypothetical future requirements. 673 55 2. 2 [](/posts/react-design-patterns-and-best-practices-for-2025-e1pcgry51 "React Design Patterns and Best Practices for 2025") Article Telerik · 1y React Design Patterns and Best Practices for 2025 Comprehensive guide covering modern React development patterns for 2025, including function components, custom hooks, Context API, TypeScript integration, and React 19 features like useOptimistic and Server Components.

The author contends that patterns like Command (which is just a function) and Strategy (which is just an interface) create unnecessary cognitive overhead and that developers naturally arrive at these solutions through iterative design without needing formal pattern terminology. The piece advocates for focusing on underlying principles rather than memorizing pattern names, suggesting that good architecture emerges from composing language features to solve problems rather than following prescribed patterns. 143 31 7. 7 [](/posts/design-patterns-for-agentic-ai-6jp4wev5d "Design patterns for agentic AI") Article Lightbend · 1y Design patterns for agentic AI The era of agentic AI has begun, with intelligent agents increasingly handling tasks and making decisions autonomously, boosting productivity. This webinar explores how these AI systems, differing from traditional SaaS tools, are built using agentic design patterns. It covers why legacy architectures are inadequate and demonstrates how platforms like Akka enable building scalable, event-driven AI agents. 122 8. 8 [](/posts/remove-42-vs-find-42-remove--xxbdpofnf "remove(42) vs. find(42).remove()") Article Yegor's Blog · 1y remove(42) vs. find(42).remove() Compares two approaches for removing objects from collections: direct removal methods versus retrieving the object first then calling remove. The retrieve-then-remove approach offers better object-oriented design through improved extensibility via decorators, more flexible error handling with null objects, and stronger encapsulation by keeping data wrapped within objects rather than exposing it as parameters. 96 9 9. 9 [](/posts/ai-ready-frontend-architecture-dx9zbqpfc "AI-Ready Frontend Architecture") Article Codemotion · 1y AI-Ready Frontend Architecture Frontend architecture is evolving to accommodate AI tools that generate, parse, and interpret code. The approach involves creating AI guidelines files to establish conventions, using component-driven development with tools like V0.dev and shadcn/ui, implementing the Use Case pattern to decouple business logic from UI, and employing middleware chains for cross-cutting concerns like logging and error handling. This architecture enables both humans and AI agents to collaborate effectively while maintaining code quality, testability, and scalability. 92 10. 10 [](/posts/how-did-mvc-get-so-f-ed-up--5fzcbqftl "How did MVC get so F’ed up?") Article Hacker News · 1y How did MVC get so F’ed up? The Model-View-Controller (MVC) pattern has been misunderstood and misimplemented over the years. The original Smalltalk MVC design keeps models completely unaware of views and controllers, using observer patterns for communication. Modern implementations, particularly Apple's Cocoa version, have corrupted this by making controllers act as intermediaries and creating tightly coupled view-controllers. True MVC requires observable models that can notify multiple views of changes, with the key insight being that models should never depend on their UI components. The pattern works as a composite where views can have their own models, and even function arguments should be treated as observable models to properly enable/disable UI elements. 84 7 11. 11 [](/posts/welcome-to-the-state-machine-pattern-5itzjs3mx "Welcome to the State Machine Pattern") Article W endell Adriel · 1y Welcome to the State Machine Pattern State machines provide a structured approach to managing complex workflows by defining explicit states, events, and transition rules. This pattern replaces tangled if/else logic with predictable, testable behavior using PHP enums, guards for validation, and actions for side effects. The implementation includes domain events with an outbox pattern to keep decision logic pure while handling side effects reliably. Key benefits include improved clarity, safety from forbidden transitions, better testability, and enhanced observability through logging and documentation generation. 84 1 12. 12 [](/posts/how-to-choose-the-best-programming-languages-libraries-and-patterns-mpqfr9vrh "How to Choose the Best Programming Languages, Libraries, and Patterns") Article freeCodeCamp · 1y How to Choose the Best Programming Languages, Libraries, and Patterns Programming decisions should be based on context and suitability rather than absolute rankings. The "Law of Suitability" suggests that the best programming language, framework, or architecture depends on specific project requirements, team constraints, and problem context. Popular choices aren't always optimal, and expert opinions should be evaluated critically. When choosing tools, consider whether they solve more problems than they create, their maintenance status, documentation quality, and footprint. Programming principles like DRY and design patterns are guidelines, not universal laws, and should be applied judiciously based on the situation. 81 4 13. 13 [](/posts/what-you-need-to-know-about-frontend-design-patterns-zzupumol8 "What you need to know about frontend design patterns") Article The Miners · 1y What you need to know about frontend design patterns Design patterns provide reusable solutions to common programming problems. Custom hooks in React exemplify this concept by allowing developers to extract and reuse stateful logic across components. The guide demonstrates how to create custom hooks for data fetching with loading states and currency formatting, showing how they improve code organization, reusability, and maintainability by separating concerns and following DRY principles. 82 1 14. 14 [](/posts/hidden-react-architecture-patterns-that-senior-developers-actually-use-vkvbegrtv "Hidden React Architecture Patterns That Senior Developers Actually Use") Article Netguru · 1y Hidden React Architecture Patterns That Senior Developers Actually Use Advanced React architecture patterns used by senior developers include Compound Component Architecture for managing shared state without prop drilling, Prop Getters pattern for creating reusable interactions with composed event handlers, and strategic choices between Controlled vs Uncontrolled components. These patterns enable building scalable, maintainable applications with cleaner APIs, better accessibility, and more intuitive component relationships through techniques like Context API, cloneElement, and state composition. 67 3 15. 15 [](/posts/choose-your-own-architecture-mani217kw "Choose your own architecture") Article ITNEXT · 1y Choose your own architecture Choosing the right software architecture depends on several factors, such as project size, domain features, team structure, and non-functional requirements like performance and fault tolerance. Different projects may require different architectural styles, including monolithic, layered, services, SOA, and more. It's essential to understand the domain characteristics and tailor the architecture to meet specific needs efficiently. 64 16. 16 [](/posts/railway-pattern-lo76ptya9 "Railway Pattern") Article RUBYLAND · 1y Railway Pattern The Railway Pattern enables fault-tolerant function composition by chaining operations that can either succeed or fail gracefully. Using Ruby gems like Dry Monads and Pipeable, developers can build robust pipelines where each step produces either a Success or Failure result, allowing errors to bubble up without breaking the entire flow. The pattern is demonstrated through building an API client that handles HTTP requests, JSON parsing, validation, and data modeling as a single composable pipeline, making code more resilient to network issues and data problems. 62 2 17. 17 [](/posts/why-go-design-patterns-still-matter-7bzplny04 "Why Go design patterns still matter") Article LogRocket · 1y Why Go design patterns still matter Explores how three specific design patterns can solve scaling challenges in Go microservices while maintaining code simplicity.

Demonstrates refactoring a tightly coupled XML feed generator by separating concerns through domain boundaries, transforming ActiveRecord models into simple data structures that isolate business logic from external APIs and database dependencies. 49 20. 20 [](/posts/when-did-people-favor-composition-over-inheritance--mcnlqine3 "When did people favor composition over inheritance?") Article Hacker News · 47w When did people favor composition over inheritance? Explores the historical origins and context of the "favor composition over inheritance" principle from the Gang of Four's Design Patterns book. Examines the three-page discussion that led to this aphorism, including the white-box versus black-box reuse distinction, language-specific considerations in Smalltalk and Java, and the compile-time versus runtime trade-offs. References Barbara Liskov's earlier work on subtypes and polymorphism, highlighting that composition and inheritance aren't the only options—first-class procedures offer a third alternative that the simplified aphorism overlooks. 41 6 21. 21 [](/posts/laravel-extended-commands-eksznaprk "Laravel Extended Commands") Article Laravel News · 40w Laravel Extended Commands A Laravel package adds Artisan commands for generating common design pattern stubs like Builders, Actions, Collections, Concerns, and Contracts.
