Is it possible to Emit custom event from client using socketio

[safaldas]

All the information in the docs to send events from server to clinet are working correctly and fine.
I need to send an event from one client to another without writing to the database.

app.io.emit('poseDetection', keypoints)

That is still what a custom service can be used for. As mentioned in the docs, a service does not have to write to the database and can be used for anything, including distributing data to other users.
