Function Inject

Parameter decorator that injects the instance associated with the given class.

Throws an error if:

• The class is not registered in the container.
• A circular dependency is detected.

Use injectBy when you need to resolve circular dependencies.

Parameter decorator that injects the value associated with the given token.

Throws an error if:

• The token is not registered in the container.
• A circular dependency is detected.

Use injectBy when you need to resolve circular dependencies.

Parameter decorator that injects the value associated with the given token.

This overload allows referencing a token declared later in the file by using the tokenRef helper function.

Throws an error if:

• The token is not registered in the container.
• A circular dependency is detected.

Use function injection with injectBy when you need to resolve circular dependencies.

Example:

class Wizard {
  constructor(@Inject(tokenRef(() => Wand)) readonly wand: Wand) {}
}
// Other code...
class Wand {}
