Function KeyRouting

KeyRouting<T extends ClassType = ClassType>(
options?: KeyRoutingOptions,
): ClassDecorator
Class decorator: enable the light key-router (route events by key, not by path).

The event-routing sibling of @Routing(): it makes the light router the kernel event handler, so any adapter that runs the kernel routes its events, keyed by a configurable property, to the matching handler (bus events, realtime gateways, CLI commands...). Mutually exclusive with @Routing(). Bundlers tree-shake the full router away when only this is used.
Type Parameters
- T extends ClassType = ClassType
Parameters
- options: KeyRoutingOptions = {}
  The key-routing configuration.
Returns ClassDecorator
A class decorator.
Example
```
@KeyRouting({ source: 'detail-type' })
@AwsLambda()
@StoneApp({ name: 'consumer' })
export class Application {}
```
