Tracking Touch Events

Use version 1.5.0 or later to track touch events with Sentry's React Native SDK. You will also need to wrap your app with a TouchEventBoundary.

Wrapping with TouchEventBoundary

At the root of your app, usually App.js, wrap the app component with Sentry.TouchEventBoundary:

import * as Sentry from "@sentry/react-native";

const App = () => {
  return (
    <Sentry.TouchEventBoundary>
      <RestOfTheApp />
    </Sentry.TouchEventBoundary>
  );
};

export default AppRegistry.registerComponent(
  "Your Amazing App",
  () => App,
);

Using the withTouchEventBoundary Higher-Order Component

At the root of your app, usually App.js, wrap the app component with Sentry.withTouchEventBoundary:

import * as Sentry from "@sentry/react-native";

const App = () => {
  return <RestOfTheApp />;
};

export default AppRegistry.registerComponent("Your Amazing App", () =>
  Sentry.withTouchEventBoundary(App),
);

Automatic Touch Tracking

Each touch event is automatically logged as a breadcrumb and displays on the dashboard when an event occurs along with the component tree in which the touch event occurred. This component tree is logged using the name property of a component. By default, React Native will set this property automatically on components.

Tracking Specific Components

You can let Sentry know which components to track specifically by passing the sentry-label prop to them. If Sentry detects a component with a sentry-label within a touch's component tree, it will be logged on the dashboard as having occurred in that component. If Sentry cannot find a component with the label, Sentry will fall back to the labelName prop if specified, or else use displayName.

const YourCoolComponent = (props) => {
  return (
    <View sentry-label="CardContainer">
      <Text sentry-label="CoolText">You are cool</Text>
    </View>
  );
};

Options

You can pass specific options to configure the boundary either as props to the Sentry.TouchEventBoundary component or as the second argument to the Sentry.withTouchEventBoundary higher-order component (HOC).

<Sentry.TouchEventBoundary
  ignoreNames={["BadComponent", /^Connect\(/, /^LibraryComponent$/]}
  labelName="testLabel"
>
  <RestOfTheApp />
</Sentry.TouchEventBoundary>;

breadcrumbCategory

String. The category assigned to the breadcrumb that is logged by the touch event.

breadcrumbType

String. The type assigned to the breadcrumb that is logged by the touch event.

maxComponentTreeSize

number, default: 20. The max number/depth of components to display when logging a touch's component tree.

ignoreNames

Array<string | RegExp>, Accepts strings and regular expressions. Component names to ignore when logging the touch event. This prevents unhelpful logs such as "Touch event within element: View" where you still can't tell which View it occurred in.

labelName

String. The name of the prop to look for when determining the label of a component. If the prop is not found, Sentry will fall back to the displayName of the component.

Minified Names in Production

When bundling for production, React Native will minify class and function names to reduce the bundle size. This means that you won't get the full original component names in your touch event breadcrumbs and instead you will see minified names. Check out our troubleshooting guide for minified production bundles documentation to solve this.
