Error Tracking for Gatsby: A Setup Guide

Production bugs in Gatsby projects are inevitable. The difference between a resilient team and a struggling one often comes down to how quickly they detect and resolve errors.

Prerequisites

Before you begin, make sure you have a Bugsly account and a Gatsby project ready to instrument. You'll need your project DSN from the Bugsly dashboard — find it under Settings > Projects > Client Keys.

Step-by-Step Integration

1. Add the Bugsly package to your Gatsby project:

npm install @bugsly/gatsby

1. Configure the SDK at your application's entry point:

// gatsby-config.js
module.exports = {
  plugins: [
    {
      resolve: "@bugsly/gatsby",
      options: {
        dsn: "YOUR_BUGSLY_DSN",
        sampleRate: 0.7,
      },
    },
  ],
};

1. Deploy your changes and verify events appear in the Bugsly dashboard.

Fine-Tuning Your Setup

After the basic integration works, consider these adjustments for Gatsby:

• Sampling rate: Adjust tracesSampleRate based on your traffic volume. High-traffic apps should sample at 0.1–0.3 to control costs.
• Environment tags: Tag events with production, staging, or development to filter noise.
• Release tracking: Pass your version string so Bugsly can track regressions across deployments.
• Custom context: Attach user IDs, request metadata, or business-specific data to events for richer debugging.

Bugsly's error tracking for Gatsby runs with minimal overhead. The SDK is designed to be lightweight, batching events and sending them asynchronously so your application performance stays unaffected.

Next Steps

Once your basic error tracking is operational, explore Bugsly's issue assignment features to route errors to the right team member automatically. Set up integrations with GitHub or GitLab to link errors directly to source code commits. Enable release tracking to see exactly which deployment introduced each issue, and use Bugsly's regression detection to catch previously-resolved bugs that resurface.
