Getting started with React Native SDK

This section describes how to set up and install the React Native SDK and how to deploy a feature flag.

Step 1 - Setting up

To setup React Native SDK, follow these steps:

  1. Create a CloudBees Rollout account. See Signup Page to create an account.

  2. Create an application in the CloudBees Rollout dashboard.

    • The first time you log into your account, click the Create New App button to create a new app.

      Create New App button

  3. Get your environment key.

    • Get the key from App Settings > Environment > Key.

Step 2 - Installing the React Native SDK

Add the CloudBees Rollout React Native library to your application by running the following npm commands:

# Add the SDK to your application
$ npm i rox-react-native --save

// For TypeScript application, also add the corresponding types:
npm i @types/rox-react-native --save

Add the following lines of code to your application:

// Import SDK
import Rox from 'rox-react-native';

// Create a Roxflag in the flags container class
const flags = {
  // Define the feature flags
  enableTutorial: new Rox.Flag(false),
  titleColors: new Rox.Variant('White', ['White', 'Blue', 'Green', 'Yellow'])

// Register the flags container
Rox.register('', flags);

// Setup the environment key
await Rox.setup("<ROLLOUT_ENV_KEY>");

// Boolean flag example
if (flags.enableTutorial.isEnabled()) {
   // TODO:  Put your code here that needs to be gated

// Multivariant flag example
if (flags.titleColors.getValue() === 'Blue') {
  console.log('Title color is blue');
} else if (flags.titleColors.getValue() === 'Green') {
  console.log('Title color is green');
} else if (flags.titleColors.getValue() === 'Yellow') {
  console.log('Title color is yellow');
} else if (flags.titleColors.getValue() === 'White') {
  console.log('Title color is white');

Container class registration and environment key setup

  • You cannot call Rox.setup() twice in the same runtime.

Run your application

Running the application

The flag name is automatically added to the CloudBees Rollout dashboard after running the application.

Step 3 - Deploying a feature flag

Finding your flags in the CloudBees Rollout dashboard

After creating feature flags and running your feature code, you can find your flags in the CloudBees Rollout dashboard.

To find your flags in the dashboard:

  1. Find your application in the CloudBees Rollout dashboard. To switch between apps, click on the app name in the top-left corner of the screen and select the app you want from the pulldown.

  2. Click on Flags on the left side of the navigation panel.

  3. Confirm that your flag is listed in the flag view.

Configuring deployment rules

  1. Go to the CloudBees Rollout dashboard.

  2. Click on Experiments on the left panel.

  3. Click the Create Experiment button to create a new experiment.

  4. In the New Experiment window:

    • Find the Flag name from the menu, choose it.

    • Click the Set Audience button to continue. The Experiment Details view appears.

  5. Select either True, False, Split or Scheduled. Split allows you to select the percentage of the target group that you want to deploy. Scheduled allows you to schedule a deployment date.


  6. Click Update Audience.

  • You cannot delete the default condition.

  • You can click the Reset link to go back to the state from before you started making changes. Reset only appears when you’ve made saved modifications.

See Audience for more detailed information.
