@capacitor-firebase/crashlytics

Unofficial Capacitor plugin for Firebase Crashlytics.¹

Installation

npm install @capacitor-firebase/crashlytics
npx cap sync

Add Firebase to your project if you haven't already (Android / iOS).

Android

See Add the Firebase Crashlytics plugin to your app and follow the instructions to set up your app correctly.

Variables

This plugin will use the following project variables (defined in your app’s variables.gradle file):

$firebaseCrashlyticsVersion version of com.google.firebase:firebase-crashlytics (default: 18.6.2)

iOS

To generate human readable crash reports, Crashlytics needs your project's debug symbol (dSYM) files. The following steps describe how to automatically upload dSYM files to Firebase whenever you build your app:

Open your project's Xcode workspace, then select its project file in the left navigator.
From the TARGETS list, select your main build target.
Click the Build Settings tab, then complete the following steps so that Xcode produces dSYMs for your builds.
1. Click All, then search for debug information format.
2. Set Debug Information Format to DWARF with dSYM File for all your build types.
Click the Build Phases tab and complete the following steps:
1. Click the + button, then select New Run Script Phase.
2. Expand the new Run Script section.
3. In the script field (located under the Shell label), add the following run script:
```
"${PODS_ROOT}/FirebaseCrashlytics/run"
```
4. In the Input Files section, add the paths for the locations of the following files:
```
${DWARF_DSYM_FOLDER_PATH}/${DWARF_DSYM_FILE_NAME}/Contents/Resources/DWARF/${TARGET_NAME}
```
```
$(SRCROOT)/$(BUILT_PRODUCTS_DIR)/$(INFOPLIST_PATH)
```

Configuration

No configuration required for this plugin.

Usage

import { FirebaseCrashlytics } from '@capacitor-firebase/crashlytics';

const crash = async () => {
  await FirebaseCrashlytics.crash({ message: 'Test' });
};

  await FirebaseCrashlytics.setCustomKey({
    key: 'page',
    value: 'home',
    type: 'string',
  });
};

const setUserId = async () => {
  await FirebaseCrashlytics.setUserId({
    userId: '123',
  });
};

const log = async () => {
  await FirebaseCrashlytics.log({
    message: 'Test',
  });
};

const setEnabled = async () => {
  await FirebaseCrashlytics.setEnabled({
    enabled: true,
  });
};

const isEnabled = async () => {
  const { enabled } = await FirebaseCrashlytics.isEnabled();
  return enabled;
};

const didCrashOnPreviousExecution = async () => {
  const { crashed } = await FirebaseCrashlytics.didCrashOnPreviousExecution();
  return crashed;
};

const sendUnsentReports = async () => {
  await FirebaseCrashlytics.sendUnsentReports();
};

const deleteUnsentReports = async () => {
  await FirebaseCrashlytics.deleteUnsentReports();
};

const recordException = async () => {
  await FirebaseCrashlytics.recordException({
    message: 'This is a non-fatal message.',
  });
};

import * as StackTrace from 'stacktrace-js';
const recordExceptionWithStacktrace = async (error: Error) => {
  const stacktrace = await StackTrace.fromError(error);
  await FirebaseCrashlytics.recordException({
    message: 'This is a non-fatal message.',
    stacktrace,
  });

Test your implementation

Here you can find more information on how to test the Firebase Crashlytics implementation. Among other things, you will find information on how to correctly adjust the project's debug settings under iOS and how to test it out.

If you get obfuscated crash reports for iOS, make sure you have initialized Crashlytics correctly and take a look at this guide, which provides some ways to troubleshoot if Crashlytics can't find your app's dSYM.
