Class: Container
Defined in: core/src/container.ts:22
Hierarchical DI container.
singleton: one instance per application (stored in the container that owns the binding)scoped: one instance per scope (e.g. per request), created in the leaf containertransient: new instance on every resolution

Constructor
> new Container(parent?): Container
Defined in: core/src/container.ts:40
Parameters
parent?
Container
Returns
Container
Methods
createScope()
> createScope(): Container
Defined in: core/src/container.ts:95
Creates a child scope (e.g. per request). Bindings are inherited; scoped instances are not.
Returns
Container
dependencyGraph()
> dependencyGraph(): DependencyGraph
Defined in: core/src/container.ts:146
The dependency graph observed so far — every A depends on B edge seen during resolution since enableGraph(). Passive: it records real resolutions and never forces eager construction.
Returns
describe()
> describe(): BindingInfo[]
Defined in: core/src/container.ts:159
Static snapshot of every reachable binding — token, lifetime, and whether it's been built.
Returns
enableGraph()
> enableGraph(): this
Defined in: core/src/container.ts:132
Enable dependency-graph recording (off by default — zero overhead otherwise).
Returns
this
