Setting Up Distributed Tracing in TypeScript

Microservices built with TypeScript need visibility across service boundaries. Distributed tracing shows you exactly where time is spent in complex request flows.

Prerequisites

Before you begin, make sure you have a Bugsly account and a TypeScript 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 TypeScript project:

npm install @bugsly/node

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

import * as Bugsly from "@bugsly/node";

Bugsly.init({
  dsn: "YOUR_BUGSLY_DSN",
  tracesSampleRate: 1.0,
});

try {
  riskyOperation();
} catch (e) {
  Bugsly.captureException(e);
}

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 TypeScript:

• 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 distributed tracing for TypeScript 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

With distributed tracing active, use Bugsly's trace explorer to find slow spans and identify bottlenecks across services. Set up performance alerts for transactions that exceed your latency budgets. Tag traces with custom attributes to filter by specific users, endpoints, or business operations.
