Java Design Patterns
Design patterns implemented in Java
A comprehensive, community-maintained collection of design pattern implementations in Java, offering well-documented, educational examples to help developers understand and apply common architectural solutions. All designs should be as simple as possible. You should start with KISS, YAGNI, and Do The Simplest Thing That Could Possibly Work principles. Complexity and patterns should only be introduced when they are needed for practical extensibility. The design patterns are now available as an e-book. Design patterns can speed up the development process by providing tested, proven development paradigms. -

TypeSpec
Language for defining cloud service APIs and shapes
...TypeSpec is excellent for generating many different API description formats, client and service codes, documentation, and many other assets. All this while keeping your TypeSpec definition as a single source of truth.

These patterns establish "guardrails" for API designers and make it easier to follow best practices than to deviate from them. TypeSpec also has a rich linter framework with the ability to flag anti-patterns as well as an emitter framework that lets you control the output to ensure it follows the patterns you want. -
