Rollbar SDK for React Native

This library is currently under heavy development, however it is usable and therefore please file an issue if you have any problems working with this library.


Getting started

Integrating this library with your React Native codebase requires the following steps:

  1. Install the package from NPM
$ npm install rollbar-react-native --save


$ yarn add rollbar-react-native
  1. Link the native modules with the underlying project:
$ react-native link rollbar-react-native
  1. Starting with version 0.3.0 that should be all you need to do. For earlier versions, download the appropriate Rollbar iOS Framework here. Extract this zip file somewhere. You will need it for the next couple steps.

  2. Open the underlying Xcode project for your app:

$ open ios/MyAwesomeApp.xcodeproj
  1. Drag the framework from the extracted zip file to be part of the RollbarReactNative project:

We recommend checking the box that says "Copy items if needed". If you are managing your vendored dependencies in some other way where you do not want to check that box, then I presume you know what you are doing.

You also need to drag the framework to be part of the main project (i.e. MyAwesomeApp) to placate the linker. This has been resolved in versions 0.3.0 and greater, but for older versions you would get a linker error without adding the framework to both projects.


If you are using Cocoapods, then you need to add the following to your pod file:

pod 'React', path: '../node_modules/react-native'
pod 'RollbarReactNative', path: '../node_modules/rollbar-react-native'

and depending on your version of React Native, you will also need:

pod 'yoga', path: '../node_modules/react-native/ReactCommon/yoga'

Then perform a pod install.

You also need to ensure the static library is linked with your app in the generated workspace like all other Cocoapods dependencies.



In your App.js file (or in older setups, both index.ios.js and files) you need to instantiate a Rollbar Client:

import { Client } from 'rollbar-react-native'
const rollbar = new Client('POST_CLIENT_ITEM_ACCESS_TOKEN');

For more configuration options, construct an instance of the Configuration class:

import { Client, Configuration } from 'rollbar-react-native'
const config = new Configuration('POST_CLIENT_ITEM_ACCESS_TOKEN', {
  endpoint: '',
  logLevel: 'info'
const rollbar = new Client(config);

The Configuration class is still a work in progress, but should eventually capture all of the configuration options available for

The Javascript API consists of the logging methods:

rollbar.log(error|message, extra, callback)
rollbar.debug(error|message, extra, callback)|message, extra, callback)
rollbar.warning(error|message, extra, callback)
rollbar.error(error|message, extra, callback)
rollbar.critical(error|message, extra, callback)

As well as two methods for dealing with identifying users:

rollbar.setPerson(id, name, email)

Source Maps

Mapping production React Native JavaScript code to your source files is slightly more complicated than traditional JavaScript environments. This is due to the fact that iOS and Android generate different JavaScript bundles, and therefore different stack traces, which need separate source maps.

You can enable source maps to correctly identify the environment by using the code_version to signal which source map to use. Please note that code_version must be nested under the client and javascript keys in order to work for source mapping.

new Configuration('POST_CLIENT_ITEM_ACCESS_TOKEN', {
  payload: {
    client: {
      javascript: {
        source_map_enabled: true,
        code_version: 'insert_code_version_here.ios',

Be sure to specify the code version when you upload the sourcemap. For example, via curl:

curl \
  -F access_token=ACCESS_TOKEN_HERE \
  -F version=insert_code_version_here.ios \
  -F minified_url=http://reactnativehost/main.jsbundle \
  -F source_map=@sourcemap.ios.js \
  -F index.ios.js=@index.ios.js

Source maps use file names for mapping minified symbols to symbols contained in your original source code. Due to the nature of the JavaScript environment that your code runs in on a mobile device using React Native, these file names are a bit strange. Rollbar automatically rewrites these file names to be http://reactnativehost/<regular file path>. This allows you to use the minified_url with the fake protocol and host of http://reactnativehost to specify your minified JavaScript code.

Generating stack traces for React Native is an under-documented part of the pipeline. Below are the commands you can use to generate conforming source maps for iOS and Android.


react-native bundle --platform ios --entry-file index.ios.js --dev false --bundle-output
ios/main.jsbundle --assets-dest ios --sourcemap-output sourcemap.ios.js --sourcemap-sources-root ./


react-native bundle --platform android --dev false --entry-file --bundle-output
android/ --assets-dest android/app/src/main/res/ --sourcemap-output --sourcemap-sources-root ./


In AppDelegate.m you need to import RollbarReactNative

#import <RollbarReactNative/RollbarReactNative.h>

and initialize it

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary*)launchOptions
  [RollbarReactNative initWithAccessToken:@"POST_CLIENT_ITEM_ACCESS_TOKEN"];

The interface for RollbarReactNative in native iOS code is the same as Crashes in native code will be reported automatically on the next app launch.


We require minSdkVersion of at least 19 be set in your app/build.gradle file.

In you need to import RollbarReactNative

import com.rollbar.RollbarReactNative;

and initialize it

public void onCreate() {
  RollbarReactNative.init(this, "POST_CLIENT_ITEM_ACCESS_TOKEN", "production");

The interface for RollbarReactNative in native Android code is the same as the rollbar-android part of Crashes in native code will be reported automatically on the next app launch.
