How to Set Up Error Monitoring in 5 Minutes

Getting Started

Error monitoring is one of those things every production app needs but too many teams put off. The good news is that modern tools make setup trivially fast. This tutorial walks you through setting up error monitoring from scratch in under 5 minutes.

We will use Bugsly for this tutorial, but the general steps apply to any error tracking tool.

Step 1: Create an Account (30 seconds)

Sign up at bugsly.dev. You can use GitHub or Google authentication for one-click signup. The free tier includes 5,000 errors per month, which is enough to get started.

Step 2: Create a Project (30 seconds)

After signing in, create a new project. Choose your platform (JavaScript, Python, Node.js, etc.). You will get a DSN (Data Source Name), which is the unique identifier for your project.

Your DSN looks something like:

https://abc123@ingest.bugsly.dev/1

Step 3: Install the SDK (1 minute)

For JavaScript / React / Next.js:

npm install @bugsly/browser

import * as Bugsly from '@bugsly/browser';

Bugsly.init({
  dsn: 'YOUR_DSN_HERE',
  environment: process.env.NODE_ENV,
});

For Python (Django / Flask / FastAPI):

pip install bugsly-sdk

import bugsly

bugsly.init(
    dsn="YOUR_DSN_HERE",
    environment="production",
)

For Node.js (Express):

npm install @bugsly/node

const Bugsly = require('@bugsly/node');
Bugsly.init({ dsn: 'YOUR_DSN_HERE' });

const app = require('express')();
app.use(Bugsly.Handlers.requestHandler());

// Your routes here

app.use(Bugsly.Handlers.errorHandler());

Step 4: Verify the Setup (1 minute)

Trigger a test error to verify everything works:

// JavaScript
try {
  throw new Error('Test error from Bugsly setup');
} catch (e) {
  Bugsly.captureException(e);
}

# Python
try:
    raise ValueError("Test error from Bugsly setup")
except Exception as e:
    bugsly.capture_exception(e)

Check your Bugsly dashboard. The test error should appear within seconds.

Step 5: Configure Alerts (1 minute)

Go to your project settings and configure notifications:

1. Slack integration: Connect your Slack workspace and choose a channel
2. Email alerts: Enable email notifications for new errors
3. Alert rules: Set up rules for error rate spikes

Optional: Add User Context

For better debugging, attach user information to errors:

Bugsly.setUser({
  id: user.id,
  email: user.email,
  name: user.name,
});

This lets you see which users are affected by each error and reach out proactively.

Optional: Upload Source Maps

For production JavaScript apps, upload source maps so stack traces show original file names and line numbers:

# During your build process
npx @bugsly/cli upload-sourcemaps ./dist \
  --release=1.0.0 \
  --project=your-project

What Happens Next

Once set up, Bugsly will automatically:

• Capture all unhandled exceptions
• Group duplicate errors into issues
• Alert you when new errors appear
• Provide AI analysis explaining the root cause
• Track error trends across releases

You now have production error monitoring. The next time something breaks, you will know about it before your users tell you.
