Introduction

If anyone has trouble setting up Datadog RUM, I would like to tell them, "The setup code for JS/NPM version has some incorrect." I have previously texted Datadog support about the feedback, but it has not been fixed, so I wrote it.

1. Typo in the snippet

As you can see in the screenshot, a snippet is provided as a sample, but unfortunately, a typo has.

Look at line 3, the curly bracket { has been used, datadogRum.init({.
But the } never has been stated in the snippet.

Here is the collect snippet.

import { datadogRum } from '@datadog/browser-rum';

datadogRum.init({
    applicationId: 'hoge-hoge-hoge',
    clientToken: 'hoge-hoge-hoge',
    site: 'datadoghq.com',
    service:'temp',

    // Specify a version number to identify the deployed version of your application in Datadog 
    // version: '1.0.0',
    sampleRate: 100,
    replaySampleRate: 100,
    trackInteractions: true,
    defaultPrivacyLevel:'mask-user-input',
});

datadogRum.startSessionReplayRecording();

2. Disabled Session Replay

If you wanna disable session replay, you also have to be careful with this setup page. There is a toggle, Session Replay Enabled, which seems to allow the snippet to be edited to disable the function.

However, only this setting doesn't seem sufficient...😅 You also must set replaySampleRate: 0

References

Set replaySampleRate to 0 to stop collecting the RUM Session Replay plan which includes replays, resources, and long tasks.

That's why here is the collect snippet!

import { datadogRum } from '@datadog/browser-rum';

datadogRum.init({
    applicationId: 'hoge-hoge-hoge-b2e3-40e049c84c81',
    clientToken: 'hoge-hoge-hoge-881b380180c1171d17',
    site: 'datadoghq.com',
    service:'temp',

    // Specify a version number to identify the deployed version of your application in Datadog 
    // version: '1.0.0',
    sampleRate: 100,
    replaySampleRate: 0,
    trackInteractions: true,
);

Happy Monitoring!
