How to Set Up Log Management in Next.js

Console.log debugging doesn't scale. For Next.js production apps, you need structured, searchable, correlated log management.

Prerequisites

Before you begin, make sure you have a Bugsly account and a Next.js 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 Next.js project:

npm install @bugsly/nextjs

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

// next.config.js
const { withBugsly } = require("@bugsly/nextjs");

module.exports = withBugsly({
  bugsly: {
    dsn: "YOUR_BUGSLY_DSN",
    tracesSampleRate: 1.0,
  },
});

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 Next.js:

• 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 log management for Next.js 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

After configuring log management, set up log-based alerts for critical patterns like authentication failures or payment errors. Use Bugsly's log correlation to connect log entries with error events and traces. Create saved searches for common debugging scenarios your team encounters regularly.
