Setting Up Performance Monitoring in Vue.js

Slow Vue.js applications lose users. Performance monitoring helps you identify bottlenecks, track regressions, and keep your app fast as it grows.

Prerequisites

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

npm install @bugsly/vue

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

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

const app = createApp(App);
app.use(Bugsly.createPlugin({
  dsn: "YOUR_BUGSLY_DSN",
  tracesSampleRate: 1.0,
}));
app.mount("#app");

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 Vue.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 performance monitoring for Vue.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

With performance monitoring in place, set up transaction-level alerts for endpoints that exceed your response time targets. Use Bugsly's performance dashboard to track web vitals and identify the slowest transactions. Enable profiling to get function-level performance data for your most critical code paths.
