Level 9: Event loop¶
Audience: Users who want to build reactive Lightning Apps and move beyond DAGs.
Prereqs: Level 8+
Drawing inspiration from modern web frameworks like React.js, the Lightning App runs all flows in an event loop (forever), which is triggered several times a second after collecting any works’ state change.
When running a Lightning App in the cloud, the
LightningWork run on different machines. LightningWork communicates any state changes to the event loop which re-executes the flow with the newly-collected works’ state.
