entityts

Entityts is a term used in software development to describe a family of patterns, libraries, and conventions for modeling and managing domain entities—objects that have a distinct identity and persist across system boundaries. The term is not tied to a single, official project, but rather to an approach focused on type safety, clear entity definitions, and reliable lifecycle management within applications, often with a TypeScript emphasis.

Core concepts commonly associated with entityts include stable identities, mutable and immutable state handling, and a defined lifecycle for entities (creation, mutation, persistence, and deletion). Central to these patterns is a schema-like definition of what constitutes an entity, along with metadata that describes properties, relationships, and validation rules. Many implementations provide a core entity store or repository abstraction, enabling consistent access, caching via identity maps, and decoupled persistence through adapters or gateways to databases, services, or remote APIs. Change tracking and event emissions are often supported to synchronize state across different parts of an application or across services.

Architecturally, entityts-inspired designs separate concerns by isolating domain models from persistence details. Entities are treated as first-class citizens with explicit identities, and operations on them are validated against defined schemas. This approach supports domain-driven design practices, facilitates testing, and can improve maintainability in complex applications by reducing implicit coupling between in-memory state and storage mechanisms.

In practice, the term may be used by various libraries or teams to describe TypeScript-friendly entity modeling, data synchronization strategies, or front-end state management patterns that emphasize predictable identity, typed definitions, and explicit change resolution.
