loader script: configure replay options

[mustafa0x]

I'm using the js-sdk-loader, which loads bundle.tracing.replay.min.js. My question is how to configure the replay options?

I tried this, but it didn't always work (due to minification, and onLoad, when loading the page the second time, was firing before all integrations were loaded).

Sentry.onLoad(() => {
    const {client} = Sentry.getCurrentHub().getStack()[0]
    Object.assign(client._integrations.Replay._recordingOptions, {maskAllInputs: false, maskAllText: false})  
})

I settled on loader.replace(/new \w+.Replay/, '$&({maskAllInputs: false, maskAllText: false})') but it's a bit hacky.

Related: it's also difficult to send the release slug when using the loader. Perhaps if a global variable can be set, that the loader reads from if present (similar to window._sentryDebugIds).

Hey @mustafa0x

My question is how to configure the replay options

You can call Sentry.init again in Sentry.onLoad and configure the replay integration there.

Sentry.onLoad(() => {
  Sentry.init({
    tracesSampleRate: 1.0,
    replaysSessionSampleRate: 0.1,
    replaysOnErrorSampleRate: 1.0,

    integrations: [
      new Sentry.Replay({
        maskAllInputs: false,
        maskAllText: false,
      }),
      new Sentry.BrowserTracing(),
    ],
  });
});

I heavily recommend setting maskAllInputs to false though as you could be sending PII or other sensitive information to Sentry.

Related: it's also difficult to send the release slug when using the loader. Perhaps if a global variable can be set, that the loader reads from if present (similar to window._sentryDebugIds).

You can set the window.SENTRY_RELEASE.id variable as a global variable for the release. See the code here:

sentry-javascript/packages/browser/src/sdk.ts

Lines 109 to 112 in 85effab

	// This supports the variable that sentry-webpack-plugin injects
	if (WINDOW.SENTRY_RELEASE && WINDOW.SENTRY_RELEASE.id) {
	options.release = WINDOW.SENTRY_RELEASE.id;
	}

Thanks @AbhiPrasad, appreciated! I can also set the release in .init() too, right? Since I'm calling it anyways.

Yup you can!

Is this answer still valid?
I'm using the Loader Script SDK 8.x with Enable Session Replay switched on.
But I get an error when trying to adjust maskAllText

<script>
window.sentryOnLoad = () => {
  Sentry.init({
    integrations: [
      new Sentry.Replay({
        maskAllText: false,
      }),
    ],
  });
};
</script>
<script src="url-copied-from-sentry-control-panel" crossorigin="anonymous"></script>

produces the following error:
TypeError: Sentry.Replay is not a constructor

Otherwise, Sentry works as expected, but I'd like to find a way to keep the text from being masked on session replays.

PS. Poking around at the Sentry object, this seems to work without throwing errors, but I'm hesitant to use it since .me isn't documented anywhere:
window.Sentry.getClient().getIntegrationByName("Replay").me.maskAllText = false
