1-1: Consider enhancing PostHog integration robustnessA few suggestions to improve the PostHog integration:
- Consider adding a check for PostHog initialization before capturing events
- Add type safety by importing PostHog types
-import posthog from "posthog-js"; +import posthog, { PostHog } from "posthog-js";
3-3: Consider adding type safety for event namesUsing string literals for event names could lead to inconsistencies. Consider creating an enum or const object for allowed event names.
export const ANALYTICS_EVENTS = { BUTTON_CLICK: 'button_click', PAGE_VIEW: 'page_view', // ... other events } as const; export type AnalyticsEvent = keyof typeof ANALYTICS_EVENTS; export const capture = (event: AnalyticsEvent, properties?: Record<string, any>)
3-9: Consider adding retry mechanism for critical eventsFor important analytics events, you might want to implement a retry mechanism or queue failed events for later retry.

26-33: LGTM! Security improvements and clean event tracking
The changes demonstrate good practices:
- Event tracking includes contextual information via the source parameter
- Window opening includes security attributes to prevent reverse tabnabbing attacks
44-51: LGTM! Consistent implementation
The changes maintain consistency with the first button handler, implementing the same security improvements and event tracking pattern.
6-6: Verify the capture function implementation
Since we're using a new shared capture function, please ensure that:
- The function properly handles all error cases
- Events are still being correctly tracked in your analytics platform
- No events are lost during the transition

1-9: Consider adding analytics queue for offline supportTo handle cases where PostHog might not be available or the user is offline, consider implementing a queue system that stores events locally and retries them when possible.
Would you like me to provide an implementation for this feature?

6-6: LGTM! Good architectural decision.The switch to a shared capture function is a solid improvement that centralizes analytics logic and makes the codebase more maintainable.
30-30: Consider extracting hardcoded URLs to configuration.While not directly related to the current changes, consider moving these URLs to a configuration file or environment variables for easier maintenance and environment-specific customization.

3-9: 🛠️ Refactor suggestion
Enhance error handling and type safety
While the basic error handling is good, there are several improvements that could make this function more robust:
- Add type safety for event names
- Validate properties before sending
- Improve error reporting
- Add initialization check
Here's a suggested implementation:
-export const capture = (event: string, properties?: Record<string, any>) => {
+type AnalyticsEvent = 'button_click' | 'page_view' | /* add other valid events */;
+
+export const capture = (event: AnalyticsEvent, properties?: Record<string, unknown>) => {
try {
+ if (!isPostHogInitialized()) {
+ console.warn('PostHog is not initialized');
+ return;
+ }
+
+ if (properties && typeof properties !== 'object') {
+ throw new Error('Properties must be an object');
+ }
+
posthog.capture(event, properties);
} catch (error) {
- console.error("Error capturing event:", error);
+ // Consider using a proper error reporting service
+ console.error(`Failed to capture analytics event: ${event}`, {
+ error,
+ properties,
+ });
}
};This implementation:
- Adds type safety for event names using a union type
- Uses
unknowninstead ofanyfor better type safety - Validates PostHog initialization
- Validates properties parameter
- Provides more detailed error logging
Please verify the list of valid analytics events for the AnalyticsEvent type.

26-33: LGTM! Security improvement for external link.
The addition of noopener,noreferrer attributes to window.open is a crucial security enhancement that prevents potential reverse tabnabbing attacks. The analytics event capture is also properly implemented with meaningful context.
44-51: LGTM! Consistent implementation.
The changes mirror the security improvements and analytics implementation from the first button handler, maintaining consistency throughout the component.
Closes #2555
