Poem

In the warren of code, a new path we dig,
For analytics' sake, and insights so big.
PostHog now listens to every small hop,
Tracking each error, each leap, every stop.
With carrots of config and burrows of logs,
We’re smarter, more nimble—thanks to PostHog!

253-258: 🛠️ Refactor suggestion

Set POSTHOG_ENABLED default to false to avoid unintended tracking.

While the addition of PostHog variables is correct, it's safer to default POSTHOG_ENABLED to false to prevent accidental analytics attempts when no key is set.

-POSTHOG_ENABLED=true
+POSTHOG_ENABLED=false
.env.docker (1)

240-244: Consider disabling PostHog by default

POSTHOG_ENABLED is set to true by default, but POSTHOG_KEY is empty. This might cause initialization attempts with an empty key. Consider setting POSTHOG_ENABLED to false by default for safer initialization.

POSTHOG_KEY=
POSTHOG_HOST=https://app.posthog.com
-POSTHOG_ENABLED=true
+POSTHOG_ENABLED=false
POSTHOG_FLUSH_INTERVAL=10000
packages/plugins/posthog/src/lib/posthog-request.middleware.ts (1)

16-26: ⚠️ Potential issue

Add error handling to prevent request pipeline interruption

The current implementation lacks error handling for the PostHog service calls. If the identify method throws an exception, it would interrupt the request pipeline.

Add a try-catch block to ensure the middleware doesn't break the request flow:

use(req: Request, res: Response, next: NextFunction) {
    // Capture essential request properties as user identification
+   try {
        this.posthog.identify(req.ip || 'anonymous', {
            $current_url: req.originalUrl,
            $referrer: req.get('referer'),
            $user_agent: req.get('user-agent'),
            $host: req.get('host'),
            $pathname: req.path,
            ip: req.ip,
            http_method: req.method
        });
+   } catch (error) {
+       // Silently continue if analytics fails
+   }

    next();
}
apps/api/src/posthog.ts (1)

24-24: Use environment object for consistency instead of direct process.env access.

You're using environment.posthog for other PostHog configuration values, but accessing process.env.POSTHOG_FLUSH_INTERVAL directly. This creates inconsistency in how environment variables are accessed.

Apply this change for consistency:

-	flushInterval: parseInt(process.env.POSTHOG_FLUSH_INTERVAL || '10000', 10),
+	flushInterval: parseInt(environment.posthog.posthogFlushInterval || '10000', 10),
🧰 Tools

[error] 24-24: Use Number.parseInt instead of the equivalent global.

ES2015 moved some globals into the Number namespace for consistency.
Safe fix: Use Number.parseInt instead.

packages/plugins/posthog/src/lib/utils/sanitizer.util.ts (1)

8-12: ⚠️ Potential issue

HTTP header comparison should be case-insensitive.

HTTP headers are case-insensitive, but the current implementation uses case-sensitive comparison. This could miss sensitive headers like 'Authorization' or 'Api-Key'.

- for (const header of this.sensitiveHeaders) {
-   if (sanitized[header]) {
-     sanitized[header] = '[REDACTED]';
-   }
- }
+ for (const header of this.sensitiveHeaders) {
+   const headerLower = header.toLowerCase();
+   for (const key in sanitized) {
+     if (key.toLowerCase() === headerLower) {
+       sanitized[key] = '[REDACTED]';
+     }
+   }
+ }

🪛 Biome (1.9.4)

[error] 8-8: Using this in a static context can be confusing.

this refers to the class.
Unsafe fix: Use the class name instead.

(lint/complexity/noThisInStatic)

packages/plugins/posthog/src/lib/posthog.plugin.ts (1)

35-35: Add IOnPluginDestroy to the implements list
A previous review comment noted that you define an onPluginDestroy() method but do not implement the IOnPluginDestroy interface. Including it would provide clearer intent and consistency.

packages/plugins/posthog/src/lib/posthog.service.ts (1)

39-41: Check for uninitialized singleton
This static method returns PosthogService.instance without verifying it was created. It can lead to runtime errors if the instance is accessed before construction.

packages/plugins/posthog/src/lib/posthog-core.module.ts (1)

63-64: Handle case where neither useClass nor useExisting is provided
A previous review noted this can cause runtime errors when both options are missing. Consider throwing an error if they are undefined to ensure safe usage.

packages/plugins/posthog/src/lib/posthog-error.interceptor.ts (3)

51-52: Use a broader exception type
This interceptor handles various exceptions, not just HttpException. Narrow typing here could cause unexpected type issues.


75-76: Use a broader exception type in captureException
Similar to the previous comment, the parameter is typed as HttpException but the method handles any exception.


387-396: Consistent visibility for helper methods
A previous review flagged that shouldReport is public while most other helper methods here are private. Aligning their visibility can improve consistency.

packages/plugins/posthog/src/lib/posthog-event.interceptor.ts (2)

70-79: ⚠️ Potential issue

Add default case to handle unknown context types

The switch statement doesn't handle the default case when context type is unknown, which could lead to silent failures.

Apply this fix:

protected captureEvent(context: ExecutionContext, eventName: string, properties: Record<string, any> = {}) {
  switch (context.getType<ContextType>()) {
    case 'http':
      return this.captureHttpEvent(context.switchToHttp(), eventName, properties);
    case 'rpc':
      return this.captureRpcEvent(context.switchToRpc(), eventName, properties);
    case 'ws':
      return this.captureWsEvent(context.switchToWs(), eventName, properties);
+   default:
+     console.warn(`Unknown context type encountered while capturing event ${eventName}`);
  }
}

230-231: 🧹 Nitpick (assertive)

Use const instead of let for variables that aren't reassigned

The statusCode variable is declared with let but never reassigned after initialization.

-let statusCode = error?.getStatus?.() || 500;
+const statusCode = error?.getStatus?.() || 500;
🧰 Tools
🪛 Biome (1.9.4)

[error] 230-230: This let declares a variable that is only assigned once.

'statusCode' is never reassigned.

Safe fix: Use const instead.

(lint/style/useConst)

packages/plugins/posthog/src/lib/posthog.interfaces.ts (1)

65-67: 🧹 Nitpick (assertive)

Improve type safety for exception filtering

The type: any could be more specific. Consider using Type<Error> or a union of common exception types for better type safety.

export interface PosthogInterceptorOptionsFilter {
-  type: any;
+  type: Type<Error> | Function;
  filter?: (exception: any) => boolean;
}

✅ Verification successful

Verify that the PostHog client version is appropriate.

The package uses posthog-node version 4.11.3. It's advisable to check if this is the latest stable version that's compatible with your application requirements.


🌐 Web query:

What is the latest stable version of posthog-node and what changes were introduced in recent versions?

💡 Result:

The latest stable version of the posthog-node library is 4.11.3, published on April 8, 2025[1].

Recent Changes in posthog-node

Here are some notable updates introduced in recent versions of the library:

  1. GeoIP Properties Changes (v3.0):

    • By default, GeoIP properties (such as city, country, and timezone) are no longer added to events to avoid incorrect resolutions based on the server's IP address. Users can revert to the old behavior by setting disableGeoip to false[2][8].
  2. Rewritten in TypeScript (v2.x.x):

    • The library was rewritten in TypeScript and is now based on a shared JavaScript core with other PostHog libraries for consistent feature updates.
    • Deprecated the callback parameter in most method implementations.
    • Adjusted method signatures for isFeatureEnabled and getFeatureFlag[2].
  3. Other Updates and Fixes:

    • Enhancements to handle race conditions when capturing events.
    • Updates to improve compatibility with older Node.js versions by replacing axios with unidici[8].
    • The disabled option was introduced, allowing users to disable tracking during testing environments without needing conditional checks[8].
    • New configuration options such as featureFlagsRequestTimeoutMs and shutdownTimeoutMs were added, improving timeout control for API calls and client shutdown[8].
    • Removed older async methods (flushAsync and shutdownAsync), integrating them directly as flush and shutdown[8].

These updates demonstrate ongoing efforts to improve the library's functionality, performance, and compatibility with modern development practices.

1-139: 🧹 Nitpick (assertive)

Fix spelling consistency for PostHog throughout codebase

The pipeline warns about the spelling of "Posthog" vs "PostHog". The product name is properly capitalized as "PostHog", but interface names use "Posthog". Consider standardizing to correct capitalization.

For consistency, you might want to rename all interfaces like:

  • PosthogModuleOptionsPostHogModuleOptions
  • PosthogEventPostHogEvent
  • PosthogInterceptorOptionsPostHogInterceptorOptions
  • etc.

Though this would be a breaking change if the API is already in use, so balance this against current adoption.

Refactor static-only class to simpler functions and avoid using this in a static context.

This class contains only static members and uses this in static methods. Consider refactoring to standalone functions or referencing the class name explicitly for clarity:

245-249: LGTM: PostHog configuration looks well-structured

The PostHog configuration is properly set up with good defaults:

  • Empty key by default (requires explicit configuration)
  • Default host pointed to PostHog cloud
  • Disabled by default for security (following previous review suggestions)
  • Reasonable flush interval (10 seconds)

20-28:

✅ Verification successful

Verify environment variable types for numeric fields.

flushInterval is read directly from environment.posthog.posthogFlushInterval. Ensure that environment.posthog.posthogFlushInterval is indeed a number, or explicitly parse it (e.g., Number.parseInt) for additional safety.


🏁 Script executed:

#!/bin/bash
# Confirm that `posthogFlushInterval` is declared and typed as a number in environment config files.
rg -A3 "posthogFlushInterval"

Length of output: 1166


Environment variable types verified – no changes required.

We confirmed that environment.posthog.posthogFlushInterval is explicitly converted using parseInt (as seen in both environment.ts and environment.prod.ts), and its type is enforced as a number in IPosthogConfig.ts. The current implementation is safe, so no additional parsing is needed in apps/api/src/posthog.ts.

✅ Verification successful

Confirm that captureException exists in posthog-node.

The official posthog-node package does not document a captureException method. Verify if you're using a custom extension or if this call should be replaced with capture:


🌐 Web query:

Does the official posthog-node library provide a `captureException` method, or is it a custom extension?

💡 Result:

The official posthog-node library does provide a captureException method, and this functionality is not a custom extension but an officially supported feature.

  • According to the release notes on Yarn for the posthog-node package, manual exception capture with full stack trace processing via the captureException function was added, and it takes distinctId as an argument[9].
  • The official PostHog Node.js documentation and tutorials primarily describe the capture method for sending custom events but do not mention captureException directly in the main docs[1][7]. However, the changelog and library documentation on Yarn confirm its existence and intent as an official feature[9].
  • The feature is analogous to the captureException method found in the PostHog JavaScript (frontend) SDK, but is now also available for backend error tracking with posthog-node[2][5].

Summary:
captureException is an official method available in the posthog-node library for manually capturing and sending exception events to PostHog. It is not a custom extension, but a core, supported feature of the SDK[9].

Citations:


Verification Result: captureException is officially supported in the posthog-node library.

After confirming via the official documentation and release notes, it is clear that the captureException method is a supported feature in posthog-node and not a custom extension. The code snippet is valid as written, and no changes are required.

111-138: Code quality: Great implementation of the parsePosthogOptions function

The validation logic in parsePosthogOptions is well-implemented, with proper validation for required fields and numeric values. The implementation also handles defaults properly with null coalescing.

1-168: 🧹 Nitpick (assertive)

Fix spelling warnings for "Posthog" and "autocapture"

The pipeline has flagged "Posthog" and "autocapture" as unknown words. Either add these to your project dictionary or adjust the naming convention if appropriate.

You could either:

  1. Add these terms to your project's cspell dictionary, or
  2. Consider standardizing the spelling of "PostHog" throughout the codebase
    (using camelCase for variables but respecting the official capitalization)

386-396: 🧹 Nitpick (assertive)

Make the shouldReport method visibility consistent with other helpers

The shouldReport method is declared with public visibility while other helper methods are private. This is inconsistent with the class design pattern.

Apply this change:

-	shouldReport(exception: any): boolean {
+	private shouldReport(exception: any): boolean {
packages/plugins/posthog/src/lib/posthog.interfaces.ts (2)

93-96: Improve type safety for filter callback function

The exception parameter in the filter callback uses any type.

 export interface PosthogInterceptorOptionsFilter {
-	type: any;
-	filter?: (exception: any) => boolean;
+	type: Type<Error>;
+	filter?: (exception: Error | unknown) => boolean;
 }

157-166: Consider handling personal API key case consistently

The function handles all other options with null coalescing but uses traditional OR for apiHost.

 return {
 	apiKey: options.apiKey,
-	apiHost: options.apiHost || 'https://app.posthog.com',
+	apiHost: options.apiHost ?? 'https://app.posthog.com',
 	enableErrorTracking: options.enableErrorTracking ?? true,
 	flushAt,
 	flushInterval,
 	personalApiKey: options.personalApiKey,
 	autocapture: options.autocapture ?? false,
 	mock: options.mock ?? false
 };

🧹 Nitpick (assertive)

Consider using more specific type in inject array

The inject property uses Type<any> which could be more specific to improve type safety.
