DataHub React Analytics
About
The DataHub React application can be configured to emit a set of standardized product analytics events to multiple backend providers including
- Mixpanel
- Amplitude
- Google Analytics
This provides operators of DataHub with visibility into how their users are engaging with the platform, allowing them to answer questions around weekly active users, the most used features, the least used features, and more.
To accomplish this, we have built a small extension on top of the popular Analytics npm package. This package was chosen because it offers a clear pathway to extending support to many other providers, all of which you can find listed here.
Configuring an Analytics Provider
Currently, configuring an analytics provider requires that you fork DataHub & modify code. As described in 'Coming Soon', we intend to improve this process by implementing no-code configuration.
Mixpanel
- Open datahub-web-react/src/conf/analytics.ts
- Uncomment the mixpanelfield within theconfigobject.
- Replace the sample tokenwith the API token provided by Mixpanel.
- Rebuild & redeploy datahub-frontend-reactto start tracking.
const config: any = {
    mixpanel: {
        token: 'fad1285da4e618b618973cacf6565e61',
    },
};
Amplitude
- Open datahub-web-react/src/conf/analytics.ts
- Uncomment the amplitudefield within theconfigobject.
- Replace the sample apiKeywith the key provided by Amplitude.
- Rebuild & redeploy datahub-frontend-reactto start tracking.
const config: any = {
    amplitude: {
        apiKey: 'c5c212632315d19c752ab083bc7c92ff',
    },
};
Google Analytics
Disclaimers
- This plugin requires use of Universal Analytics and does not yet support GA4. To create a Universal Analytics Property, follow this guide.
- Google Analytics lacks robust support for custom event properties. For that reason many of the DataHub events discussed above will not be fully populated. Instead, we map certain fields of the DataHub event to the standard category,action,labelfields required by GA.
- Open datahub-web-react/src/conf/analytics.ts
- Uncomment the googleAnalyticsfield within theconfigobject.
- Replace the sample trackingIdwith the one provided by Google Analytics.
- Rebuild & redeploy datahub-frontend-reactto start tracking.
const config: any = {
    googleAnalytics: {
        trackingId: 'UA-24123123-01',
    },
};
Verifying your Analytics Setup
To verify that analytics are being sent to your provider, you can inspect the networking tab of a Google Chrome inspector window:
With DataHub open on Google Chrome
- Right click, then Inspect
- Click 'Network'
- Issue a search in DataHub
- Inspect the outbound traffic for requests routed to your analytics provider.
Development
Adding a plugin
To add a new plugin from the Analytics library:
- Add a new file under src/app/analytics/pluginnamed based on the plugin
- Extract configs from the analytics config object required to instantiate the plugin
- Instantiate the plugin
- Export a default object with 'isEnabled' and 'plugin' fields
- Import / Export the new plugin module from src/app/analytics/plugin/index.js
If you're unsure, check out the existing plugin implements as examples. Before contributing a plugin, please be sure to verify the integration by viewing the product metrics in the new analytics provider.
Adding an event
To add a new DataHub analytics event, make the following changes to src/app/analytics/event.ts:
- Add a new value to the EventTypeenum
   export enum EventType {
    LogInEvent,
    LogOutEvent,
    ...,
    MyNewEvent
}
- Create a new interface extending BaseEvent
export interface MyNewEvent extends BaseEvent {
    type: EventType.MyNewEvent; // must be the type you just added
    ... your event's custom fields
}
- Add the interface to the exported Eventtype.
export type Event =
    | LogInEvent
    | LogOutEvent
    ....
    | MyNewEvent
Emitting an event
Emitting a tracking DataHub analytics event is a 2-step process:
- Import relevant items from analyticsmodule
import analytics, { EventType } from '../analytics';
- Call the eventmethod, passing in an event object of the appropriate type
analytics.event({ type: EventType.MyNewEvent, ...my event fields });
Debugging: Enabling Event Logging
To log events to the console for debugging / verification purposes
- Open datahub-web-react/src/conf/analytics.ts
- Uncomment logging: truewithin theconfigobject.
- Rebuild & redeploy datahub-frontend-reactto start logging all events to your browser's console.
Coming Soon
In the near future, we intend to
- Send product analytics events back to DataHub itself, using them as feedback to improve the product experience.
- No-code configuration of Analytics plugins. This will be achieved using server driven configuration for the React app.
