Signature:

binding: (bindingKey?: string | BindingKey<unknown>, metadata?: InjectBindingMetadata) => (target: Object, member: string | undefined, methodDescriptorOrParameterIndex?: number | TypedPropertyDescriptor<any> | undefined) => void

Parameters

Returns:

(target: Object, member: string | undefined, methodDescriptorOrParameterIndex?: number | TypedPropertyDescriptor<any> | undefined) => void

Example

class MyAuthAction {
  @inject.binding('current-user', {
    bindingCreation: BindingCreationPolicy.ALWAYS_CREATE,
  })
  private userBinding: Binding<UserProfile>;

  async authenticate() {
    this.userBinding.toDynamicValue(() => {...});
  }
}
