Sentry

Sentry is an error tracking and performance monitoring platform that helps you solve problems and continuously learn about your apps. The @amazon-devices/sentry__react-native library implements the React Native SDK for Sentry on the Vega platform.

During this phase, some of the Sentry features are not setup for Vega. You can post questions or report issues on the Vega Developer Forums.

Installation

1. Add the JavaScript library dependency in the package.json file.

    dependencies: {
        "@sentry/react-native": "npm:@amazon-devices/sentry__react-native@~1.0.10"
    }
   

2. Install dependencies using the npm install command.

Examples

Initialize Sentry on the top-level of your app, using the Sentry.init({...}) method. The only required parameter is dsn, short for Data Source Name. Find the dsn from the Sentry project's settings page.

import * as Sentry from '@sentry/react-native';
import React from 'react';
import {View, Button, Text} from 'react-native';

// init Sentry somewhere top-level outside of component
Sentry.init({
  // set environment variable SENTRY_DSN to your project's dsn
  // or inline your DSN here
  dsn: process.env.SENTRY_DSN,
});

export function App() {
  const captureMessage = () => {
    // send message directly to Sentry
    Sentry.captureMessage('SentryAppDemo message');
  };

  const captureException = () => {
    // capture exception and send it to Sentry
    Sentry.captureException(new Error('SentryAppDemo error'));
  };

  return (
    <View
      style={{
        backgroundColor: '#181a1b',
        padding: 32,
        flex: 1,
        flexDirection: 'column',
        gap: 16,
      }}>
      <Text style={{fontSize: 32, color: 'white'}}>Sentry App Demo</Text>
      <View style={{width: '25%'}}>
        <Button onPress={captureMessage} title="Capture Message" />
      </View>
      <View style={{width: '25%'}}>
        <Button onPress={captureException} title="Capture Exception" />
      </View>
    </View>
  );
}

After initializing Sentry, all uncaught exceptions are found automatically and reported by Sentry. You don't need to send events manually.

You can add extra information to the Sentry events using Sentry.setContext() or Sentry.setUser(), as shown.

import * as Sentry from '@sentry/react-native';
import React from 'react';
import {View, Button, Text} from 'react-native';

// init Sentry somewhere top-level outside of component
Sentry.init({
  // set environment variable SENTRY_DSN to your project's dsn
  // or inline your DSN here
  dsn: 'process.env.SENTRY_DSN',
});

export function App() {
  const setContext = () => {
    // add custom data to Sentry events
    Sentry.setContext('ExampleContext', {
      category: 'ExampleCategory',
      message: 'ExampleMessage',
      level: 'info',
    });
  };

  const throwError = () => {
    // throw error without catching - Sentry will report this for us
    throw new Error('SentryAppDemo uncaught error');
  };

  return (
    <View
      style={{
        backgroundColor: '#181a1b',
        padding: 32,
        flex: 1,
        flexDirection: 'column',
        gap: 16,
      }}>
      <Text style={{fontSize: 32, color: 'white'}}>Sentry App Demo</Text>
      <View style={{width: '25%'}}>
        <Button onPress={setContext} title="Set Context" />
      </View>
      <View style={{width: '25%'}}>
        <Button onPress={throwError} title="Throw Error" />
      </View>
    </View>
  );
}

Additional configuration

Add readable stack traces to Sentry errors

In summary, after the app is built, you should notify Sentry about the app release name, version, and dist number and send sourcemaps of the JavaScript bundle and debug files. This ensures that Sentry catches events and correctly maps the information with readable stack traces.

After building the app, you might have a similar folder structure:

├── sentrydemoapp
│   ├── build
│   │   ├── lib
│   │   │   ├── rn-bundles
│   │   │   │   ├── Debug #use the path for debug build
│   │   │   │   ├── Release #use the path for release build
│   │   ├── x86_64-release
│   │   │   ├── debug #use the path for app meant for simulator for x86 machines
│   │   ├── armv7-release
│   │   │   ├── debug #use the path for app meant for Fire TV Stick
│   │   ├── aarch64-release
│   │   │   ├── debug #use the path for app meant for simulator for M-series machines

1. In the Sentry initialization, create a release version and a dist version. You need to define $SENTRY_RELEASE_VERSION (for example, my-vega-project@2.3.12) and $SENTRY_DIST_NUMBER (for example 52). See Sentry official docs for more information.

    Sentry.init({
      release: process.env.SENTRY_RELEASE_VERSION,
      dist: process.env.SENTRY_DIST_NUMBER,
    });
   

2. Add Sentry Metro Serializer to metro.config.js and rebuild the application.

    ...
    const {createSentryMetroSerializer} = require('@sentry/react-native/dist/js/tools/sentryMetroSerializer');
    ...
   
    const sentryMetroSerializer = createSentryMetroSerializer()
   
    const config = {
      serializer: {
        customSerializer(entryPoint, preModules, graph, options) {
          return sentryMetroSerializer(entryPoint, preModules, graph, options)
        },
      },
    };
   
    module.exports = mergeConfig(getDefaultConfig(__dirname), config);
   

3. Install sentry-cli. See Sentry official docs for more information.

    curl -sL https://sentry.io/get-cli/ | sh
   

4. Create a new Sentry release. Pass the previously defined $SENTRY_RELEASE_VERSION. See Sentry official docs for more information.

    sentry-cli releases new $SENTRY_RELEASE_VERSION
   

5. Upload source maps for JavaScript symbolication. Please note that sentry-wizard is not yet supported. See Sentry official docs for more information.

    # inside Vega app directory
    # BUILD_TYPE is either Debug or Release
    # --release and --dist flags are optional when using Debug IDs
    sentry-cli sourcemaps upload "build/lib/rn-bundles/$BUILD_TYPE" --release "$SENTRY_RELEASE_VERSION" --dist "$SENTRY_DIST_NUMBER"
   

After sending the information to Sentry, you get precise information regarding where errors occur in your app.
