Realtime & WebSockets

Analytics & Telemetry Ingestion

Track pageviews, button clicks, user conversion funnels, and performance beacons. Ingest events singly or in batches, and query aggregated session summaries in real time without external analytics vendor tracking.

Interactive Telemetry Workbench

Select a telemetry scenario below to send live tracking beacons or inspect aggregated session metrics:

Track Pageview Beacon

Ingests a single pageview event with route path, referrer, and user device properties.

POST

response.json

{

// Click "Send" above to execute this request against the live server.

}

Telemetry Event Payload Schema

The /analytics/track endpoint accepts structured JSON beacons:

Field	Type	Required	Description
event	string	Yes	Unique event identifier (e.g. `pageview`, `checkout_completed`).
properties	object	Optional	Arbitrary key-value metadata dictionary (route path, currency, user agent).
timestamp	string (ISO-8601)	Optional	Client-side event capture time (defaults to server receipt time if omitted).

Client Integration Code

Production patterns for guaranteed unload delivery and batching:

// Browser Telemetry with navigator.sendBeacon (Guaranteed On-Unload)

export function trackBeacon(eventName: string, properties: Record<string, any> = {}) {

const url = 'https://playground.nileslabs.com/api/v1/analytics/track';

const payload = JSON.stringify({

event: eventName,

properties,

timestamp: new Date().toISOString(),

});

if (typeof navigator !== 'undefined' && navigator.sendBeacon) {

const blob = new Blob([payload], { type: 'application/json' });

navigator.sendBeacon(url, blob);

} else {

fetch(url, {

method: 'POST',

headers: { 'Content-Type': 'application/json' },

body: payload,

keepalive: true,

}).catch(() => {});

}
