Sentry Hello World

Name: sentry-hello-world
Author: jeremylongshore

Overview

Capture your first error and verify Sentry integration is working correctly.

Prerequisites

Sentry SDK installed and initialized
Valid DSN configured
Network access to Sentry servers

Instructions

Step 1: Capture Test Error

import * as Sentry from '@sentry/node';

try {
  throw new Error('Hello Sentry! This is a test error.');
} catch (error) {
  Sentry.captureException(error);
  console.log('Error sent to Sentry');
}

Step 2: Capture Test Message

Sentry.captureMessage('Hello from Sentry SDK!', 'info');

Step 3: Verify in Dashboard

Open https://sentry.io
Navigate to your project
Check Issues tab for the test error
Verify event details are correct

Step 4: Add Context

Sentry.setUser({ id: 'test-user', email: 'test@example.com' });
Sentry.setTag('test_run', 'hello-world');
Sentry.captureMessage('Test with context');

Output

Test error visible in Sentry dashboard
Event contains stack trace and metadata
User context and tags attached to event

Error Handling

Error	Cause	Solution
Event not appearing	DSN misconfigured	Verify DSN in project settings
Delayed events	Network latency	Wait 30-60 seconds, check again
Missing stack trace	Source maps not uploaded	Configure source map uploads
No user context	setUser not called	Add Sentry.setUser() before capture

Examples

Full Test Script (TypeScript)

import * as Sentry from '@sentry/node';

Sentry.init({ dsn: process.env.SENTRY_DSN });

// Set user context
Sentry.setUser({ id: '123', email: 'test@example.com' });

// Set tags
Sentry.setTag('environment', 'test');
Sentry.setTag('version', '1.0.0');

// Capture different event types
Sentry.captureMessage('Info message', 'info');
Sentry.captureMessage('Warning message', 'warning');

try {
  throw new Error('Test exception');
} catch (e) {
  Sentry.captureException(e);
}

console.log('Events sent - check Sentry dashboard');

Python Test Script

import sentry_sdk

sentry_sdk.init(dsn=os.environ.get('SENTRY_DSN'))

sentry_sdk.set_user({'id': '123', 'email': 'test@example.com'})
sentry_sdk.set_tag('environment', 'test')

sentry_sdk.capture_message('Hello from Python!')

try:
    raise ValueError('Test exception from Python')
except Exception as e:
    sentry_sdk.capture_exception(e)
