Developer Docs Xp Stable Framework Events

Events

Contents

Send and listen to local or cluster wide events

Introduction

The XP framework enable developers to create and/or listen to events. Events may be local (within a single server) or cluster wide (distributed to all servers within a cluster). In addition to application specific events, XP itself produces a range of standard events.

Use cases

The use cases for events are limitless, but the most common are:

  • Cache invalidation

  • Notifications (i.e. notify clients connected to any server in the cluster via Websocket)

  • Job triggering

Implementation

For implementation details, please visit the event library documentation.
