Container registry

containerRegistry maps scope objects to Container instances. It backs resolve(), request scope, and React Native-safe multi-container apps.

Global singleton

import { containerRegistry } from "@brushy/di-core";

containerRegistry.setDefaultContainer(appContainer);
const container = containerRegistry.getContainer();

Scoped registration

const testScope = { testRun: 1 };
containerRegistry.registerContainer(testScope, testContainer);

containerRegistry.getContainer(testScope); // testContainer

API

Method	Description
`setDefaultContainer(container)`	Fallback when no scope matches
`getContainer(scope?)`	Resolve container for scope or default
`hasDefaultContainer()`	Whether default is set
`registerContainer(scope, container)`	Bind container to scope
`unregisterContainer(scope)`	Remove scope binding
`cleanupTransientScopes()`	Clear Map-based transient scopes

Uses WeakMap for long-lived scope keys and Map for transient scopes (React Native safe, without FinalizationRegistry).

`ROOT_SCOPE`

Sentinel constant for the root scope bucket in internal scoped caches.

Integration with ALS

getContainer() without arguments calls getActiveScope() from request scope store. When ALS has an active scope and a container is registered for it, that container wins over the default.

`inject.setGlobalContainer`

Convenience wrapper around setDefaultContainer:

import { inject } from "@brushy/di-core";

inject.setGlobalContainer(container);

Error

Throws DependencyError when no default container exists and no scoped container matches:

No container found. Use registerContainer() or setDefaultContainer()

See resolve & inject.
