Approach which help to define boundaries for a large application According it we can flexibly adapt and maintain mutable functionality of app.

There are multiple mentions and interpretations of feature-driven approach (see below)

This article contains common rules and principles.

  Summary - "Feature Driven Architecture" talk

UPD (Jan 2021) Also, should be mentioned:

• Feature Slices

Benefits

• Discoverability - discover how your software works
• Work parallesisation - to dev software by teams, not alone
• Controlling shared abstractions - controlling abstractions, for preventing bugs and controlling software
• Refactoring - we can be sure what user-facing functionality we will affect
• AB Tests - more controllable experiments, with quikly manipulating (many-ifs hell)
• Integration tests - other tests can't cover all app logic, but integration tests is difficult to create and maintain (more meaningful an easy way)

Concepts

• **Decentralization** - organize app by explicit abstractions, no interconnected monolith (app ⇒ pages ⇒ features ⇒ shared)
• Explicit sharing - explicit rules for managing shared (common used) modules
