Bundle Deep Dive

Ubiquitous Language

Understand business terms, list them. Propose adaptation if ambiguity.

Domain Core

Identify what carries business meaning. Need key entities. What is domain/ application/infra (logic from legacy code is not DDD)

Mainly in src/.../[Entity, Model, Repository, Controller]/ paths

Invariants / Concistency

Understand what's always be true, list them as rule.

Cross-context Dependencies

Map coupling in contexts of bundles.

DDD Slicing

Define migration-safe target model.

• Aggregates (target)
• Value Objects (first candidates)
• Domain services to extract
• Repository interfaces (domain-facing)
• Domain events (optional first)

Reading Order

Fast onboarding for understanding bundle
