Software Design Patterns for Modern Apps

1- Command Query Responsibility Segregation (CQRS): This pattern separates READ and WRITE operations for a data store to increase performance, scalability and security.
2
3- Domain-Driven Design (DDD): This is a software development approach that emphasizes collaboration between technical experts and domain experts to iteratively refine a complex, evolving model of the problem domain.
4
5- Event Sourcing (ES): This pattern involves saving all changes to the application state as a sequence of events, which can then be replayed to recreate the current state, and allows sophisticated data analysis and debugging (eg. EventSource DB)
6
7- Microservices Architecture: This approach breaks down an application into loosely coupled, independently deployable components (microservices) that each do one thing well, allowing for flexibility in development and scaling.
8
9- Hexagonal Architecture (also known as Ports and Adapters): This pattern isolates the application's core logic from the outside world (databases, UI, etc.) via a system of ports and adapters, promoting testability and decoupling the core business logic from infrastructure concerns.
10
11- Reactive Architecture: This software design approach aims to create applications that are more flexible, loosely-coupled, and scalable, and which can handle and respond to changes in their environment or user demands in real-time, typically using event-driven programming and asynchronous message-passing.
