OpenReplay Tracker MobX plugin

A MobX plugin for OpenReplay Tracker. This plugin allows you to see the MobX events during session replay.

Installation

npm i @openreplay/tracker-mobx

Usage

Initialize the @openreplay/tracker package as usual and load the plugin into it. Then put is as a second argument to observe function from mobx package.

import Tracker from '@openreplay/tracker';
import trackerMobX from '@openreplay/tracker-mobx';
import { observe } from 'mobx';

const tracker = new Tracker({
  projectKey: YOUR_PROJECT_KEY,
});

const mobxTrackerInstance = tracker.use(trackerMobX(options)); // look below for available options
observe(yourMobxStore, mobxTrackerInstance)

Options:

interface Options {
    predicate?: (observeEvent: { type: string; name: string; object: any; debugObjectName: string }) => boolean;
    sanitize?: (resultAction: { state: any; type: string; property: string }) => { state: any; type: string; property: string };
    update?: boolean;
    add?: boolean;
    delete?: boolean;
}

trackerMobX({
  predicate: () => true,
  sanitize: (event) => event
})

Where predicate can be used to dynamically turn off capturing and sanitize can be used to modify the payload before sending it to backend. Most of the actions fall into update type, refer to mobx documentation for more details about add and delete (mostly for Maps)
