# Awesome Software Architecture<br/>
  
[![awesome-badge](https://awesome.re/badge.svg)](https://awesome.re)
  
[Software architecture](https://en.wikipedia.org/wiki/Software_architecture) aims to describe the high level 
structures of software as well as the discipline of creating them. As this topic is pretty broad, it might 
contain some resources that are also present in more niche lists.

## Principles
- [Flexibility](https://medium.com/faun/flexibility-a-software-architecture-principle-6eafe045a1d4) - Able to adapt to changes in both environment and usability requirements without encompassing structural changes.
- [SOLID](https://www.[digitalocean](/@harrisonqian/awesome/wiki/platforms/digitalocean).com/community/conceptual-articles/s-o-l-i-d-the-first-five-principles-of-object-oriented-design) - Lend to developing software with considerations for maintaining and extending as the project grows

## Design Patterns
- [Ports and adapters pattern](https://jmgarridopaz.[github](/@harrisonqian/awesome/wiki/development-environment/github).io/content/hexagonalarchitecture.html) - Decouple the application [core](/@harrisonqian/awesome/wiki/platforms/core) logic from the services it uses.
- [Observer pattern](https://medium.com/datadriveninvestor/design-patterns-a-quick-guide-to-observer-pattern-d0622145d6c2) - One-to-many state change notification.

- [Event Sourcing](https://docs.microsoft.com/en-us/azure/architecture/patterns/event-sourcing) - Instead of storing just the current state of the data in a domain, use an append-only store to record the full series of actions taken on that data.
- [Feature Toggles](https://www.martinfowler.com/articles/feature-toggles.html) - Feature Toggles (often also refered to as Feature Flags) are a powerful technique, allowing teams to modify system behavior without changing code.
- [Behavior Driven Development (BDD) and Functional Testing](https://medium.com/javascript-scene/behavior-driven-development-bdd-and-functional-[testing](/@harrisonqian/awesome/wiki/testing/testing)-62084ad7f1f2) - BDD uses human-readable descriptions of software user requirements as the basis for software tests.
