v2.0.0

⚠️ Breaking Changes

• @splunk/otel-web
  • Anonymous User Tracking Enabled by Default #1579
    • Changed the default value of user.trackingMode from noTracking to anonymousTracking
    • The agent now generates a persistent anonymous user ID (_splunk_rum_user_anonymousId) stored via the configured persistence method (default: cookie)
    • This enables:
      • User journey correlation across sessions
      • Issue diagnosis by tracking user behavior patterns
      • Digital experience analytics without identifying individual users
    • Migration: Users who do not want this behavior can explicitly set user.trackingMode: 'noTracking' in their configuration
    • Example:

      SplunkRum.init({
      	realm: 'us0',
      	rumAccessToken: '....',
      	user: {
      		trackingMode: 'noTracking', // Opt out of anonymous tracking
      	},
      })

New Features and Improvements

• @splunk/otel-web-session-recorder

  • Added Session Replay Sampling #1577

    • Introduced SessionBasedSampler to control the percentage of sessions that get recorded by session recorder

    • SplunkRum takes a ratio of all possible sessions, e.g. 0.8 means 80% of all possible sessions will be sent to the backend

    • SplunkSessionRecorder also takes a ratio of all possible sessions, e.g. 0.02 means that replay will be recorded for the 2% of all possible sessions

    • Note that if you record 20% of the sessions, and you want the replay for 10% of recorded sessions then you need to multiply: 0.2 * 0.1 = 0.02, so the ratio for SplunkRum is 0.2 and the ratio for SplunkSessionRecorder is 0.02

    • We ensure that if the replay is recorded then the session itself is recorded and that the ratios are preserved

    • Example usage:

      // Example 1: Record 30% of all sessions (independent of agent sampling)
      SplunkSessionRecorder.init({
      	realm: 'us0',
      	rumAccessToken: '....',
      	sampler: new SplunkRum.SessionBasedSampler({ ratio: 0.3 }), // records 30% of sessions
      })
      
      // Example 2: If agent samples 80% and you want session recorder to record 20% of ALL sessions
      // (not 20% of the agent-sampled sessions), use:
      SplunkRum.init({
      	realm: 'us0',
      	rumAccessToken: '....',
      	sampler: new SplunkRum.SessionBasedSampler({ ratio: 0.8 }), // agent samples 80%
      })
      SplunkSessionRecorder.init({
      	realm: 'us0',
      	rumAccessToken: '....',
      	sampler: new SplunkRum.SessionBasedSampler({ ratio: 0.2 }), // records 20% of all sessions
      })
      // Result: 20% of all sessions will have session replay
      
      // Example 3: If agent samples 80% and you want session recorder to record 20% of of the agent-sampled sessions, use:
      SplunkRum.init({
      	realm: 'us0',
      	rumAccessToken: '....',
      	sampler: new SplunkRum.SessionBasedSampler({ ratio: 0.8 }), // agent samples 80%
      })
      SplunkSessionRecorder.init({
      	realm: 'us0',
      	rumAccessToken: '....',
      	sampler: new SplunkRum.SessionBasedSampler({ ratio: 0.16 }), // 0.8 * 0.2 = 0.16
      })

      • Bug fixes included:
        • Replay export is now scoped to the current session. This fixes a case where the last chunk from the previous session could be attached to a new session
        • Recording now re-checks sampling when a new session starts, not just on the first page load. This prevents sessions from being skipped when sampling changes across sessions

• @splunk/otel-web

  • Added Experimental Data Attributes Capture #1537
    • Added __experimental_dataAttributesToCapture config option to capture custom data-* attributes from clicked elements
    • Captured attributes are attached to click and rage click spans
    • Supports both hyphenated and camelCase format for attribute names
    • Example:

      SplunkRum.init({
      	realm: 'us0',
      	rumAccessToken: 'YOUR_TOKEN',
      	applicationName: 'my-app',
      	__experimental_dataAttributesToCapture: [
      		'data-testid', // hyphenated format
      		'track', // camelCase format (looks up data-track)
      		'userName', // camelCase format (looks up data-user-name)
      	],
      })

    • When a button with these attributes is clicked, the span will include:
      • element.dataset.testid: "submit-btn"
      • element.dataset.track: "purchase"
      • element.dataset.userName: "john-doe"
  • Added Page Completion Time (PCT) Metric for SPAs #1536

    • Introduced a new SpaMetricsManager for measuring page load times in Single Page Applications (SPAs)

    • Unlike traditional page load metrics that rely on browser navigation events, this monitors actual resource loading activity to determine when a page has finished loading

    • When enabled, PCT is automatically recorded as the duration of every routeChange span in your application

    • How PCT is calculated:

      • When a user navigates within your SPA (clicking links, tabs, or menu items), the timer starts
      • Monitors all resource loading activity (API calls, images, stylesheets, etc.)
      • Uses a quiet period detection algorithm - waits for a configurable period (default: 5 seconds) with no new resource activity
      • The total time is recorded as the duration of the routeChange span

    • Disabled by default - must be explicitly enabled in configuration

    • How to enable:

      // Option 1: Enable with defaults
      SplunkOtelWeb.init({
      	realm: 'us0',
      	rumAccessToken: 'your-token',
      	applicationName: 'my-spa-app',
      	_experimental_spaMetrics: true,
      })
      
      // Option 2: Enable with custom configuration
      SplunkOtelWeb.init({
      	realm: 'us0',
      	rumAccessToken: 'your-token',
      	applicationName: 'my-spa-app',
      	_experimental_spaMetrics: {
      		quietTime: 3000, // 3 seconds quiet period (default: 5000ms)
      		maxResourcesToWatch: 50, // Limit tracked resources (default: 100)
      		ignoreUrls: [/analytics/], // Additional URLs to ignore
      	},
      })

v1.1.0

1.1.0

• @splunk/otel-web

  • Collect Text from Clicked Elements #1332
    • Click events now capture text content from the clicked elements with privacy-first defaults
    • Default Behavior: By default, only the element's tag name is collected (e.g., [Button]), ensuring no sensitive information is captured
    • Masking & Unmasking: Use maskAllText and sensitiveRules configuration options to control text capture behavior, similar to session replay functionality
    • Examples:
      • Default: Clicked to '[Button]' for <button>Potentially sensitive text</button>
      • After explicitly unmasking: Clicked to 'Potentially sensitive text'
    • See documentation for details on masking configuration

• @splunk/otel-web-session-recorder

  • Add browser compatibility guard and enable polyfills for session recorder CDN bundle #1450
    • Prevents session recorder initialization in unsupported browsers and enables automatic polyfill injection for the CDN bundle.

v1.0.1

1.0.1

v1.0.0

1.0.0

🎉 We're out of beta! This is the first stable release of Splunk OpenTelemetry JavaScript Web SDK.

Breaking Changes

This release includes several breaking changes as we graduate from beta to stable:

• @splunk/otel-web

  • Removed Legacy Build Support #1366

    • Dropped support for legacy browsers (Internet Explorer)
    • The legacy build that provided IE compatibility has been removed

  • Removed Deprecated and Experimental APIs #1331

    • All APIs marked as deprecated in previous versions have been removed
    • All experimental APIs (prefixed with _experimental_) have been removed or promoted to stable
    • Removed deprecated configuration options:
      • app - Use applicationName instead
      • beaconUrl - Use beaconEndpoint instead
      • environment - Use deploymentEnvironment instead
      • rumAuth - Use rumAccessToken instead
    • Removed deprecated API methods:
      • SplunkRum._experimental_getGlobalAttributes() - Use SplunkRum.getGlobalAttributes() instead
      • SplunkRum.error(...args) - Use SplunkRum.reportError(error, context) instead
      • SplunkRum._experimental_addEventListener(name, callback) - Use SplunkRum.addEventListener(name, callback) instead
      • SplunkRum._experimental_removeEventListener(name, callback) - Use SplunkRum.removeEventListener(name, callback) instead
      • SplunkRum._experimental_getSessionId() - Use SplunkRum.getSessionId() instead

  • Session Management Changes #1289

    • Session lifecycle management has been simplified and now works independently
    • Sessions are extended only when click, scroll, touch, and keydown events are detected
    • Previously, we extended sessions based on the _experimental_allSpansExtendSession and _experimental_longtaskNoStartSession config options. These options are no longer supported and can be removed from your configuration.

• @splunk/otel-web-session-recorder

  • Session Recorder Breaking Changes #1330

    • Removed rrweb dependency - The session recorder no longer uses the external rrweb library
    • Replaced with Splunk's native recorder - Session recording is now handled by Splunk's proprietary, more efficient recording engine
    • Removed recorderType configuration option - The recorder: 'rrweb|splunk' option is no longer supported
    • Please refer to the Record browser sessions docs for more details.

  • Session Replay Enhancements #1368

    • Added persistFailedReplayData option to improve replay data reliability (set to true by default)
    • When persistFailedReplayData is enabled, data that we are unable to send to Splunk is persisted to local storage and sent again when the page is reloaded.
    • There is a 2MB limit for data stored in local storage

Migration Guide

If you're upgrading from a previous version, please ensure:

1. Update your configuration to use the new option names:

   // Before (deprecated)
   SplunkRum.init({
   	app: 'my-app',
   	beaconUrl: 'https://...',
   	environment: 'production',
   	rumAuth: 'token',
   })
   
   // After (stable)
   SplunkRum.init({
   	applicationName: 'my-app',
   	beaconEndpoint: 'https://...',
   	deploymentEnvironment: 'production',
   	rumAccessToken: 'token',
   })

2. Update your API calls to use the stable methods:

   // Before (deprecated)
   SplunkRum._experimental_getGlobalAttributes()
   SplunkRum.error('Something went wrong')
   
   // After (stable)
   SplunkRum.getGlobalAttributes()
   SplunkRum.reportError('Something went wrong')
