Usage

To use Coralogix SDK, call CoralogixRum.init(options) at the soonest available moment after the app loads. This will initialize the SDK based on the options you provided.

import { CoralogixRum } from '@coralogix/react-native-sdk';

CoralogixRum.init({
  application: 'app-name',
  environment: 'production',
  public_key: 'abc-123-456',
  coralogixDomain: 'EU2',
  version: 'v1.0.3',
  labels: {
    payment: 'visa',
  },
  ignoreErrors: ['some error message to ignore'],
  sessionSampleRate: 100, // Percentage of overall sessions being tracked, Default to 100%
});

To provide contextual information or transmit manual logs, utilize the exported functions of CoralogixRum. Keep in mind that these functions will remain inactive until you've invoked CoralogixRum.init().

import { CoralogixRum } from '@coralogix/react-native-sdk';

// Update user context dynamically
CoralogixRum.setUserContext({
  user_id: '123',
  user_name: 'name',
  user_email: '[email protected]',
  user_metadata: {
    role: 'admin',
    // ...
  },
});

// Update custom labels dynamically
CoralogixRum.setLabels({
  ...CoralogixRum.getLabels(),
  paymentMethod: 'visa',
  userTheme: 'dark',
  // ...
});

// Update application context dynamically
CoralogixRum.setApplicationContext({
  application: 'app-name',
  version: '1.0.0',
});

CoralogixRum.log(CoralogixLogSeverity.Error, 'this is a log', { key: 'value' });
CoralogixRum.error('this is a log with error severity', { key: 'value' });

View Tracking

To track views, set the view context whenever a view changes.

CoralogixRum.setViewContext({
  view: 'Home',
});

You can automatically track view changes by using react-navigation.

<NavigationContainer
  ref={navigationRef}
  onStateChange={() => {
    const currentRouteName = navigationRef.current.getCurrentRoute().name;

    CoralogixRum.setViewContext({ view: currentRouteName });
  }}
>
  >{/* ... */}
</NavigationContainer>

Instrumentation's

Turn on/off specific instrumentation, default to all trues. Each instrumentation is responsible for which data the SDK will track and collect for you.

CoralogixRum.init({
  // ...
  instrumentations: {
    fetch: false,
    custom: true,
    errors: true,
  },
});

Ignore Errors

The ignoreErrors option allows you to exclude errors that meet specific criteria. This options accepts a set of strings and regular expressions to match against the event's error message. Use regular expressions for exact matching as strings remove partial matches.

import { CoralogixRum } from '@coralogix/react-native-sdk';

CoralogixRum.init({
  // ...
  ignoreErrors: [/Exact Match Error Message/, 'partial/match'],
});

TraceParentInHeader

Add trace context propagation in headers across service boundaries

CoralogixRum.init({
  // ...
  traceParentInHeader: {
    enabled: true,
    options: {
      // When the backend domain is different from the app domain, specifying backend domains is necessary.
      propagateTraceHeaderCorsUrls: [new RegExp('https://webapi.*')],
      // B3 propagation
      propagateB3TraceHeader: {
        singleHeader: true,
        multiHeader: true,
      },
      // Aws propagation
      propagateAwsXrayTraceHeader: true,
    },
  },
});

beforeSend

Enable event access and modification before sending to Coralogix, supporting content modification, and event discarding.

CoralogixRum.init({
  // ...
  beforeSend: (event) => {
    // Discard events from @company.com users.
    if (event.session_context.user_email?.endsWith('@company.com')) {
      return null;
    }

    // Redact sensitive information.
    event.session_context.user_email = '***@***'

    return event;
  },
});

Proxy Url

Proxy configuration to route requests.
By specifying a proxy URL, all RUM data will be directed to this URL via the POST method. However, it is necessary for this data to be subsequently relayed from the proxy to Coralogix. The Coralogix route for each request that is sent to the proxy is available in the request’s cxforward parameter (for example, https://www.your-proxy.com/endpoint?cxforward=https%3A%2F%2Fingress.eu1.rum-ingress-coralogix.com%2Fbrowser%2Fv1beta%2Flogs).

CoralogixRum.init({
  // ...
  coralogixDomain: 'EU1',
  proxyUrl: 'https://www.your-proxy.com/endpoint',
});
