Decorators Overview

redi provides parameter decorators to declare and configure dependencies. Here’s a quick reference.

Injection Decorators

Declare what dependencies should be injected. See Declare Dependency for details.

Decorator	Description
`@Inject(id)`	Inject a required dependency
`@Optional(id?)`	Inject an optional dependency (returns `null` if not found)
`@Many(id?)`	Inject all instances as an array

Control where dependencies are resolved. See Hierarchy Injection for details.

Decorator	Description
`@Self()`	Only look in current injector
`@SkipSelf()`	Skip current, look in parent
`@InjectSelf()`	Inject the Injector itself

Modify how dependencies are resolved.

Decorator	Description
`@WithNew()`	Create a new instance (skip singleton cache)

Most decorators can be combined. For example: @SkipSelf() @Optional(IConfig) looks for an optional dependency only in parent injectors.
