const MiddlewareConfig: ReactNativeConfiguration = {
    serviceName: 'Mobile-SDK-ReactNative',
    projectName: '$Mobile-SDK-ReactNative',
    accountKey: '<middleware-account-key>',
    target: '<target-url>',

    globalAttributes: {
        name: '<your-name>',
    },
};

export default function App() { 
    return (
      <MiddlewareWrapper configuration={MiddlewareConfig}>
        // Application Components
      </MiddlewareWrapper>
    );
  }

Custom logging

You can add custom logs such as debug, error, warn, info these logs will be shown on Middleware Logs Dashboard

MiddlewareRum.debug("I am debug");
MiddlewareRum.error("I am error");
MiddlewareRum.info("I am info");
MiddlewareRum.warn("I am warn");

You can set global attributes by calling setGlobalAttributes function.

MiddlewareRum.setGlobalAttributes({

    "app.version": "1.0.0",
    "custom_key": "some value"
});

MiddlewareRum.updateLocation(latitude: number, longitude: number)

Enable session recording

By default session recording is enabled, to disable session recording pass sessionRecording: false configuration as follows -

const MiddlewareConfig: ReactNativeConfiguration = {
    serviceName: 'Mobile-SDK-ReactNative',
    projectName: '$Mobile-SDK-ReactNative',
    accountKey: '<middleware-account-key>',
    target: '<target-url>',
    sessionRecording: false,
    deploymentEnvironment: 'PROD',
    globalAttributes: {
        name: '<your-name>',

};

Sanitizing views in session recording

Views will get blurred hiding sensitive information in session recording.

<MiddlewareSanitizedView>
  <Component/>
</MiddlewareSanitizedView>
