Design Patterns for Reusable Software
Design patterns are battle-tested solutions to recurring design problems. They provide a shared vocabulary for structuring code that is flexible, testable, and easier to maintain as requirements change.
The patterns in this collection cover creational, structural, and behavioral categories with language-specific examples. Use them to recognize familiar problems and apply proven solutions instead of reinventing structure.
Every resource includes clear explanations, copy-paste code, and practical warnings. Use them to make informed decisions, avoid production pitfalls, and speed up your delivery. If you are just getting started, read the beginner-friendly articles first; if you are experienced, jump straight to the advanced patterns and architecture guides. New resources are added regularly, so bookmark this page and check back for the latest patterns.
