Requirements

• React Native >= 0.72.3
• iOS >= 13.4
• Android minSdkVersion >= 21

Installation

1. Install the package:

   npm install @luciq/react-native
   # or
   yarn add @luciq/react-native

2. Expo only. Add the Luciq config plugin to app.json:

   {
     "expo": {
       "plugins": [
         [
           "@luciq/react-native",
           {
             "addScreenRecordingBugReportingPermission": true
           }
         ]
       ]
     }
   }

   addScreenRecordingBugReportingPermission is optional — when true, the plugin adds the iOS microphone & photo-library usage descriptions and the Android FOREGROUND_SERVICE_MEDIA_PROJECTION permission required for screen recording in bug reports.

3. iOS only. Install CocoaPods:

   cd ios && pod install && cd ..

Initializing Luciq

Call Luciq.init once, as early as possible — at the top of your entry file (index.js or App.tsx), outside any component. InvocationEvent is a named export, not a property on the default Luciq namespace.

import Luciq, { InvocationEvent } from '@luciq/react-native';

Luciq.init({
  token: 'APP_TOKEN',
  invocationEvents: [InvocationEvent.shake],
});

You can combine multiple invocation events:

Luciq.init({
  token: 'APP_TOKEN',
  invocationEvents: [
    InvocationEvent.shake,
    InvocationEvent.screenshot,
    InvocationEvent.floatingButton,
  ],
});

Available InvocationEvent values: shake, screenshot, twoFingersSwipe, floatingButton, none.

Find your app token in your Luciq dashboard under Settings → SDK Integration.

iOS Usage Descriptions

Luciq needs microphone access to capture audio during screen recordings, and photo-library access to let users attach images to bug reports. Apple rejects apps that omit usage descriptions for either, so add the following keys to your app's Info.plist:

• NSMicrophoneUsageDescription
• NSPhotoLibraryUsageDescription

Suggested copy:

• "<app name> needs microphone access to record audio with screen recordings attached to bug reports."
• "<app name> needs photo-library access to attach images to bug reports."

The permission prompts only appear when a user actually starts a screen recording or attaches a photo from the Luciq UI.

Source Map Uploads for Crash Reports

For your app crashes to show fully symbolicated stack traces, the build scripts in @luciq/react-native will generate and upload source maps to your dashboard on release builds. The uploader reads your app token from the Luciq.init({ token: 'YOUR_APP_TOKEN' }) call in JavaScript.

If your token is defined as a constant or imported from elsewhere, override the lookup with environment variables:

| Variable | Purpose | | --------------------------------- | ------------------------------------- | | LUCIQ_APP_TOKEN | App token used for the upload | | LUCIQ_APP_VERSION_NAME | Overrides the inferred versionName | | LUCIQ_APP_VERSION_CODE | Overrides the inferred versionCode | | LUCIQ_SOURCEMAPS_UPLOAD_DISABLE | Set to TRUE to skip the upload step |

Network Logging

Network logging is enabled by default. It intercepts fetch and XMLHttpRequest calls and attaches them to outgoing reports. Disable it with:

import { NetworkLogger } from '@luciq/react-native';

NetworkLogger.setEnabled(false);

Repro Steps

Luciq Repro Steps record the screens a user visits. Each screen is attached to a bug report when it's sent. Repro Steps are enabled by default.

React Navigation

v5+ — pass Luciq.onStateChange to your NavigationContainer:

import { NavigationContainer } from '@react-navigation/native';
import Luciq from '@luciq/react-native';

<NavigationContainer onStateChange={Luciq.onStateChange}>{/* ... */}</NavigationContainer>;

v4 and below — wire Luciq.onNavigationStateChange to the root app:

export default () => <App onNavigationStateChange={Luciq.onNavigationStateChange} />;

React Native Navigation (Wix)

Register Luciq.componentDidAppearListener:

import { Navigation } from 'react-native-navigation';
import Luciq from '@luciq/react-native';

Navigation.events().registerComponentDidAppearListener(Luciq.componentDidAppearListener);

Manual screen reporting

For custom navigation, report screen changes yourself:

Luciq.reportScreenChange('CheckoutScreen');

Disabling Repro Steps

import Luciq, { ReproStepsMode } from '@luciq/react-native';

Luciq.setReproStepsConfig({ all: ReproStepsMode.disabled });

ReproStepsMode values: enabled, enabledWithNoScreenshots, disabled.

Custom Spans (APM)

Custom spans let you manually instrument arbitrary code paths for performance tracking — useful for operations that aren't covered by the automatic instrumentation.

Start / end a span

import { APM } from '@luciq/react-native';

const span = await APM.startCustomSpan('Load User Profile');

if (span) {
  try {
    await loadUserProfile();
  } finally {
    await span.end();
  }
}

Record a completed span

import { APM } from '@luciq/react-native';

const start = new Date(Date.now() - 1500);
const end = new Date();

await APM.addCompletedCustomSpan('Cache Lookup', start, end);

Behavior

• Limit: up to 100 concurrent spans at a time.
• Name length: truncated to 150 characters; empty names are rejected.
• Timestamps: endDate must be after startDate; otherwise the span is rejected.
• Idempotent: calling span.end() more than once is safe.
• Gating: spans are only created when the SDK is initialized, APM is enabled, and the custom-spans feature is enabled for your account.

API reference

APM.startCustomSpan(name: string): Promise<CustomSpan | null>

Starts a custom span. Returns the span object, or null if the span couldn't be created (e.g. feature disabled, span cap reached, invalid name).

CustomSpan.end(): Promise<void>

Ends the span and reports it. Idempotent.

APM.addCompletedCustomSpan(name: string, startDate: Date, endDate: Date): Promise<void>

Records a span whose start and end times are already known.

TypeScript

The package ships with type definitions. The public surface is exposed as:

• Luciq (default export) — top-level SDK actions: init, onStateChange, onNavigationStateChange, componentDidAppearListener, reportScreenChange, setReproStepsConfig, and many more.
• Named modules: APM, BugReporting, CrashReporting, FeatureRequests, NetworkLogger, Replies, SessionReplay, Surveys.
• Named enums: InvocationEvent, ReproStepsMode, LogLevel, NetworkInterceptionMode, Locale, ColorTheme, WelcomeMessageMode, ExtendedBugReportMode, NonFatalErrorLevel, and more.
• Named types: LuciqConfig, ThemeConfig, NetworkData, Survey, SessionMetadata.

import Luciq, {
  APM,
  BugReporting,
  CrashReporting,
  InvocationEvent,
  NetworkLogger,
  ReproStepsMode,
  type LuciqConfig,
} from '@luciq/react-native';
