Decorator for custom events

[hakimio]

Is there any decorator which can be used for handling custom events like the following:

await this.srv.emit('OrderedBook', { book, quantity, buyer: req.user.id });

[hakimio]

Is it just @UnboundActions()?

Hi,
@UnboundActions can be used to have Unbound actions ( actions / functions that are not bound to an entity )

[hakimio]

@dragolea how do you handle custom events?

[dragolea]

Hi,
You can use the UnboundActions decorator to handle custom actions for a service, those actions which are not bound to an entity but to the service itself.

Hope I understood correctly your question, if not plese just reply again.

Sorry for delay,

Regarding this question with the emit

await this.srv.emit('OrderedBook', { book, quantity, buyer: req.user.id });

You can use @Inject(SRV) private readonly srv : Service to access the CDS application service which can be used yo have the emit method

But currently we do not have a decorator for emit, we plan to have this feature in the near future.

[hakimio]

So, it's not possible to listen to events emitted this way with @UnboundActions() controller?
How do you handle this type of events in your own application? Do you just manually subscribe with this.srv.on()?

Hi,

That decorator can be used only for unbound actions and functions which are not bound to an actual entity

Maybe you can provide me a code snippet and an actual requirement of what you want to achieve, so we can have in our coming release that feature.

P.S. please open an issue for a new Requirement, we will be more than. happy to help you.
