A function that you provide to Redux Beacon for each Redux or ngrx/store action you want to track.


function eventDef(action, prevState, nextState) {
// Return:
// - an event object, or
// - an array of event objects, or
// - a Promise that resolves to an event object, or
// - a Promise that resolves to an array of event objects


  • Redux Beacon calls every event definition with three arguments:

    • action: The action object.

    • prevState: The state before the action.

    • nextState: The state after the action.

Typescript Type

import { EventDefinition } from 'redux-beacon';
