Unstated
Unstated is a React state management library that encapsulates application state and update logic within decoupled containers. It functions as a container-based state store, allowing state and business logic to be organized into standalone classes that trigger component re-renders when data changes.
The project serves as a dependency injection framework, enabling specific state container instances to be supplied to the component tree. This mechanism supports the use of mock containers or stubs to facilitate controlled testing and custom configurations.
The library covers global state management and application state decoupling, moving logic away from the user interface. It ensures component state synchronization by passing shared instances through the application tree to keep multiple interface elements in sync with a single data source.
Features
- Application State Managers - Provides a framework to manage application variables and business logic to trigger interface updates.
- State Containers - Provides architectural components that manage global application state through centralized data stores.
- Dependency Injection Frameworks - Implements inversion of control to supply specific state container instances to the component tree.
- Container-Based Encapsulations - Wraps state and logic within standalone classes to decouple data management from the component view hierarchy.
- State Synchronization - Ensures multiple interface elements stay synchronized with a single data source by passing shared containers.
- Global State Managers - Maintains a global application state shared across various UI components in the browser.
- Context-Based Instance Distribution - Passes state containers through the application tree to ensure multiple components access a single shared instance.
- Dependency Injection Patterns - Implements patterns for providing state and methods to nested components without manual prop drilling.
- Component-Based State Management - Passes container instances through a tree hierarchy to automatically synchronize and update the UI.
- Modular State Sharing - Stores state and logic in decoupled containers that can be shared across independent application modules.
- State Management Libraries - Provides a library for managing application state in web interfaces by encapsulating logic in decoupled containers.
- Observation-Based Rendering - Triggers UI re-renders automatically when the underlying state container notifies the component of a change.
- Class-Based Logic Organization - Organizes related state variables and update methods within a single class structure to decouple logic from the UI.
- Test Service Injections - Allows swapping real state containers with mock implementations for deterministic and controlled testing.
- State Dependency Injection - Supplies specific container instances to the application to facilitate stubbing and custom configuration during testing.
