Getting Started

To get started with Nucleus, create an account at Nucleus and grab the App ID, then use the SDK to start tracking events.

Installation

This package has @react-native-async-storage/async-storage and @react-native-community/netinfo as peer dependencies. Install them first if you don't have them

yarn add @react-native-async-storage/async-storage @react-native-community/netinfo

then proceed to install nucleus-rn As NPM package (recommended)

# with yarn
yarn add nucleus-rn

Usage

import Nucleus from 'nucleus-rn';

Nucleus.init('YOUR_APP_ID');

Replace 'YOUR_APP_ID' with the unique ID of your app. You can get it here.

You can check examples with different frameworks here.

API

Nucleus supports passing the following options as second argument to the Nucleus.init() method:

Nucleus.init('APP_ID', {
  appVersion: '0.0.0', // the version of your application
  endpoint: 'wss://app.nucleus.sh', // only option, we don't allow self hosting yet :(
  disableInDev: true, // disable in development mode. We recommend not to call
                      // `init` method, as that will be more reliable.
  debug: false, // if set to `true`, will log a bunch of things.
  disableTracking: false, // will not track anything. You can also use `Nucleus.disableTracking()`.
                          // note that some events will still be added to the queue, so if you call
                          // Nucleus.enableTracking() again, they will be sent to the server.
  reportInterval: 2 * 1000, // at which interval the events are sent to the server.
  sessionTimeout: 60 * 30 * 1000, // time after which the session is ended
  cutoff: 60 * 60 * 48 * 1000, // time after which event that were not sent yet are deleted
  disableErrorReports: false, // wether to disable error tracking
})

Tracking

Track events with optional custom data

Nucleus.track("click", { foo: 'bar' });

Error Tracking

Track errors with a name and the Error object.

Nucleus.trackError(name, error);

By default Nucleus registers a handler for ErrorUtils.setGlobalHandler that sends 'GlobalError' errors to the API. If you want to disable this behaviour, you can set disableErrorReports to true:

Nucleus.init('APP_ID', { disableErrorReports: true })

and catch errors manually using Nucleus.trackError('an error', errObject).

User Identification

Identify a user by a unique ID and optionally set custom properties.

Nucleus.identify('04f8846d-ecca-4a81-8740-f6428ceb7f7b', { firstName: 'Jordan', lastName: 'Walke' });

Screen Tracking

Track screen views with the screen name and optional parameters.

Nucleus.page('/about', { foo: 'baz' });

Disabling Tracking

To disable tracking

Nucleus.disableTracking();

Enabling Tracking

To enable tracking

Nucleus.enableTracking();
