Value Objects Sindri

Value Object pattern for Python and Domain Driven Design applications

Easy use and customizable implementation for the Value Object pattern.

Getting Started  •  Value Object Pattern

Sindri value object replaces ad hoc primitives and fragile validators with a consistent Value Object and Aggregate toolkit you can adopt quickly. Spin up validated value objects and aggregates with a simple and a small, focused API. Why use it? Building your domain with Sindri lets you: ⏱️ Cut domain modeling and validation to seconds 🛡️ Declare immutable, validated value objects with clear error messages 🧩 Model aggregates with explicit invariants and composition 🧰 Start from ready made primitives and identifiers or extend with your own 🔧 Plug in custom validators, decorators, and typed primitives

Create a value object and use it in your domain:

from value_object import Integer, String

age = Integer(30)
name = String("John Doe")

print(f"Name: {name.value}, Age: {age.value}")
