Configuration

Options for Pulse.start() — the JS-layer initialization call.

For native-side configuration, see the platform SDK references: iOS SDK Initialization · Android SDK Configuration.

Pulse.start(options?)

Pulse.start({
    autoDetectExceptions: true,   // JS crash and error detection
    autoDetectNetwork:    true,   // HTTP request interception
    autoDetectNavigation: true,   // kill switch for navigation tracking
});

All options default to true. Pass false to disable an instrumentation.

Option	Default	Description
autoDetectExceptions	true	Global JS error handler — catches unhandled exceptions and promise rejections
autoDetectNetwork	true	Intercepts XMLHttpRequest / fetch / axios — zero code changes required
autoDetectNavigation	true	Kill switch — set to false to completely disable navigation tracking. Tracking requires the useNavigationTracking hook regardless — see Navigation Instrumentation.

Network Header Capture

Capture specific request or response headers alongside network spans:

Pulse.start({
    networkHeaders: {
        requestHeaders:  ['x-request-id', 'x-trace-id'],
        responseHeaders: ['x-response-time', 'cache-control'],
    },
});

Shutdown

Permanently shuts down the SDK. Cannot be reversed in the same process.

Pulse.shutdown();
