The profiler plugin allows you to measure your JS functions' performance and capture both arguments and result for each function
call.
Installation
{`npm i @openreplay/tracker-profiler --save`}
Usage
Initialize the tracker and load the plugin into it. Then decorate any function inside your code with the generated function.
Usage
{`import OpenReplay from '@openreplay/tracker';
import trackerProfiler from '@openreplay/tracker-profiler';
//...
const tracker = new OpenReplay({
projectKey: '${projectKey}'
});
// .start() returns a promise
tracker.start().then(sessionData => ... ).catch(e => ... )
//...
export const profiler = tracker.use(trackerProfiler());
//...
const fn = profiler('call_name')(() => {
//...
}, thisArg); // thisArg is optional`}
}
second={
{`import OpenReplay from '@openreplay/tracker/cjs';
import trackerProfiler from '@openreplay/tracker-profiler/cjs';
//...
const tracker = new OpenReplay({
projectKey: '${projectKey}'
});
//...
function SomeFunctionalComponent() {
useEffect(() => { // or componentDidMount in case of Class approach
// .start() returns a promise
tracker.start().then(sessionData => ... ).catch(e => ... )
}, [])
//...
export const profiler = tracker.use(trackerProfiler());
//...
const fn = profiler('call_name')(() => {
//...
}, thisArg); // thisArg is optional
