React-Native Monitoring for react-navigation
components
Datadog Real User Monitoring (RUM) enables you to visualize and analyze the real-time performance and user journeys of your application’s individual users. This specific package adds support to the react-navigation
library.
Setup
Note: This package is an integration for react-navigation
library, please make sure you first install and setup the core mobile-react-native
SDK.
To install with NPM, run:
npm install @datadog/mobile-react-navigation
To install with Yarn, run:
yarn add @datadog/mobile-react-navigation
Track view navigation
To track changes in navigation as RUM Views, set the onReady
callback of your NavigationContainer
component as follow. You can use the optional ViewNamePredicate
parameter to replace the automatically detected View name with something more relevant to your use case.
Returning null
in the ViewNamePredicate
prevents the new RUM View from being created. The previous RUM View remains active.
import * as React from 'react';
import { DdRumReactNavigationTracking, ViewNamePredicate } from '@datadog/mobile-react-navigation';
import { Route } from "@react-navigation/native";
const viewNamePredicate: ViewNamePredicate = function customViewNamePredicate(route: Route<string, any | undefined>, trackedName: string) {
return "My custom View Name"
}
function App() {
const navigationRef = React.useRef(null);
return (
<View>
<NavigationContainer ref={navigationRef} onReady={() => {
DdRumReactNavigationTracking.startTrackingViews(navigationRef.current, viewNamePredicate)
}}>
// …
</NavigationContainer>
</View>
);
}
Note: Only one NavigationContainer
can be tracked at the time. If you need to track another container, stop tracking the previous one first, using DdRumReactNavigationTracking.stopTrackingViews()
.
