PostHog error tracking for Hono
— the description by PostHog

AutoGineer summary

Written by AutoGineer from the skill’s own files, not by the author

This skill provides guidance on implementing PostHog error tracking within Hono applications. It covers the essential setup, including SDK initialization, environment variable management, and the use of manual capture for specific error boundaries. The skill emphasizes maintaining existing error handling structures while enhancing observability through PostHog's monitoring, alerting, and issue assignment features.

What it does

  • Provides instructions for installing PostHog error tracking in Hono.
  • Explains how to use environment variables for secure configuration.
  • Outlines best practices for using manual capture at error boundaries.
  • Details how to upload source maps for readable stack traces.
  • Describes how to configure alerts for new or spiking issues.
  • Covers manual and automatic issue assignment to team members.

When to use it

  • When you need to monitor runtime exceptions in a Hono-based application.
  • When you want to receive notifications for critical application errors.
  • When you need to triage and assign errors to specific team members.
  • When you want to improve debugging by resolving minified stack traces.

Advantages

  • Integrates seamlessly without requiring a rewrite of existing error handling.
  • Enables proactive monitoring through automated alerting.
  • Supports team collaboration via issue assignment and filtering.
  • Improves error clarity by supporting source map uploads.

Usage examples

“How do I initialize PostHog in my Hono app for error tracking?”
The skill provides the necessary steps to initialize the SDK, emphasizing the use of environment variables for your project keys and host URL.
“How can I get notified when a new error occurs in my Hono service?”
The skill guides you to the PostHog error tracking configuration page to set up alerts for Slack, Discord, or webhooks.

PostHog error tracking for Hono

This skill helps you add PostHog error tracking to Hono applications.

Consult the documentation for API details and framework-specific patterns.

Key principles

  • Environment variables: Always use environment variables for PostHog keys and host URLs. Never hardcode them.

  • Minimal changes: Add error tracking alongside existing error handling. Don't replace or restructure existing error handling code.

  • Autocapture first: Enable exception autocapture in the SDK initialization before adding manual captures.

  • Source maps: Upload source maps so stack traces resolve to original source code, not minified bundles.

  • Manual capture for boundaries: Use captureException() at error boundaries and catch blocks for errors that don't propagate to the global handler.

Assign issues to teammates - Docs

Error tracking enables you to assign issues to specific PostHog roles or teammates. This helps your team find relevant issues through filtering. You can also set up team-specific alerting to notify them when assigned issues are created or reopened.

Assign issues

You can manually assign issues as you triage them in the UI. This can be done both in the issue list and issue detail pages.

  1. In your error tracking issue list, click the unassigned selector under each issue to assign it to a role or user.

  2. On the detail page of each issue, click the Assignee selector to assign it to a role or user.

Want to assign issues to a team rather than an individual teammate? You can create a role in your project settings.

Automatic issue assignment

You can set up automatic issue assignment through a set of rules. This can be configured in the error tracking settings using auto assignment rules.

Assignment conditions are evaluated against the properties of the exception event that created the issue. Because assignment rules are evaluated during ingestion, the stack trace (if present) will be unminified, which enables filtering on exception properties such as function name and source file.

Issues can be automatically assigned to a role or user by configuring a set of filters. These filters can be configured to match any or all of the criteria.

You can configure automatic assignment to filter on any event property in PostHog. When there are multiple values for a property, the filters return true if it matches any of the values. For example, if you have multiple exception_functions values, the filters returns true if it matches any of the functions.

Here are some common properties you can filter on:

PropertyEvent propertyDescription
Exception type$exception_typesThe type of exception(s) that occurred
Exception message$exception_valuesThe message(s) detected on the error
Exception function$exception_functionsThe function(s) where the exception occurred
Exception source$exception_sourcesThe source file(s) where the exception occurred
Exception was handled$exception_handledWhether the exception was handled by the application
Device type$device_typeThe type of device that the error occurred on
Browser$browserThe browser that the error occurred in
Current URL$current_urlThe URL that the error occurred on
Feature flag$feature_flagThe feature flag that the error occurred on

You can also set custom properties on the error tracking event to filter on. For example, setting a custom params_received property to provide more context or debug information.

Order of issue assignment rules

Issue assignment filters are evaluated in the order they are configured. They can also be reordered once created. The first filter that matches is used to assign the issue. This means you should configure the most specific filters first, and then the more general filters later.

Disabled assignment rules

Assignment rules can become disabled if an error occurs during ingestion. When a rule is disabled, a banner displays the original error message. To re-enable the rule, edit it to fix the problem and save your changes. If the issue persists, reach out to support.

Alerting based on assignment

A common use case for automatic issue assignment is to alert assignees of new issues. Once the issues are automatically assigned, you can set up alerts to notify the assignee. See the alerts guide for more information.

Create external issues

You can also create issues in external tracking systems like GitHub Issues, Linear, GitLab, or Jira.

First, set up an integration with your tracking system. Then, from an issue's details page, under External references, click Create issue.

The new issue will have a partial stack trace and a link to the issue in PostHog.

If you use another issue tracking system and would like to request it, let us know in-app.
