SRP slapfight—bring popcorn
Challenging the Single-Responsibility Principle
Dev world splits: stop chopping code, reuse more, and yes—microservices catch strays
TLDR: An essay argues devs overuse a “one job per piece” rule, urging reuse and a simple grouping method instead. Comments explode: purists defend the rule’s true meaning, cynics roast microservices as sprawling messes, and jokesters pile on—showing how coding principles shape real-world complexity and team sanity.
A spicy essay poked the bear: the author says the “single-responsibility principle” (SRP) is being weaponized to slice software into confetti, birthing spaghetti code and “distributed monoliths.” Their fix? Minimize code, maximize use cases, and sort pieces by a “blood group law”: generic tools (Group 0), tech helpers (Group T), business rules (Group A), and a big red flag combo (AT) to avoid. Think “reuse more, rewrite less,” with Quasar-style categories as the label maker.
Cue comment-section fireworks. Purists charge misrepresentation: HeavyStorm insists SRP means a class has one “reason to change,” not one line per job. Pragmatists clap, blaming overzealous SRP and microservice mania for turning teams into networked hairballs—scuff3d claims every “microservice” they’ve seen is just a far-flung monolith. Comedians arrive with acronym wordplay like “KISS my DRY SOLID goodbye,” and movie jokes about the post ending right as it got juicy. Meanwhile, Nevermark adds nuance, saying the grouping idea works recursively inside each domain, winning nods from architecture nerds. The vibe: half the crowd wants stricter definitions, half wants fewer boxes and more reuse, and everyone wants less chaos. It’s a code-culture clash with memes and receipts, and the popcorn is well-seasoned.
Key Points
- •The article critiques over-application of the Single-Responsibility Principle (SRP) for causing excessive fragmentation.
- •It promotes a mantra: minimize overall code and maximize reusable use cases across an organization.
- •It introduces Siedersleben’s “blood group law” from the Quasar architecture style to classify components.
- •Groups are defined as 0 (generic), T (technical), A (domain), and AT (an anti-pattern with T calling A).
- •Developers should refactor A components toward 0/T and avoid AT to improve reusability and maintainability.
