openreplay/tracker/tracker-profiler

OpenReplay Tracker profiler plugin

The profiler plugin allows you to measure function performance and capture the arguments and result for each function call.

Installation

npm i @openreplay/tracker-profiler

Usage

Initialize the @openreplay/tracker package as usual and load the plugin into it. Then decorate any function inside your code with the generated function.

import Tracker from '@openreplay/tracker';
import trackerProfiler from '@openreplay/tracker-profiler';

const tracker = new Tracker({
  projectKey: YOUR_PROJECT_KEY,
});
// .start() returns a promise
tracker.start().then(sessionData => ... ).catch(e => ... )

export const profiler = tracker.plugin(trackerProfiler());

const fn = profiler('call_name')(() => {
  // ...
}, thisArg); // thisArg is optional
