Astro Session Replay: Complete Setup Guide

Overview

Imagine watching a video of every user who encountered a bug in your Astro app. That's what session replay gives you — complete visual context for every error.

Bugsly provides a first-class Astro integration for session replay that takes minutes to set up and immediately starts delivering value.

Installation and Setup

Start by adding Bugsly to your project:

npx astro add @bugsly/astro

Next, initialize the SDK in your application:

// astro.config.mjs
import bugsly from "@bugsly/astro";

export default defineConfig({
  integrations: [
    bugsly({ dsn: "YOUR_BUGSLY_DSN", tracesSampleRate: 1.0 }),
  ],
});

How It Works

Once initialized, the Bugsly Astro SDK automatically instruments your application. Here's what happens behind the scenes:

• Automatic error capture: Unhandled exceptions and promise rejections are caught and reported with full stack traces
• Context enrichment: Each event includes environment data, request details, and user context where available
• Intelligent grouping: Similar errors are grouped together so you see issues, not individual events
• Performance data: Transaction traces help you understand the performance impact of errors

Customizing Your Integration

For Astro projects, we recommend enabling these additional features after the basic setup:

1. Source maps (if applicable) — upload source maps during your build so Bugsly can display readable stack traces
2. User feedback — prompt users who encounter errors for additional context
3. Custom tags — add business-specific metadata to events for filtering and analysis

Bugsly's dashboard will become your team's go-to tool for understanding what's happening in your Astro production environment.
