Getting started with Node.js SDK

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

Step 1 - Setting up

The following are prerequisites for installing the Node.js SDK:

Create a CloudBees Feature Management account. See Signup Page to create an account.
Get your environment key. Copy your environment key from App settings > Environments > Key.

Step 2 - Installing the Node.js SDK

Add the CloudBees Feature Management Node.js library to your application by running the following npm commands:

# # Add node.js SDK package as your application dependency
$ npm i rox-node --save

# For TypeScript projects, also add the corresponding types:
npm i @types/rox-node --save

Add the following lines of code to your application:

import Rox from 'rox-node';

const flags = {
  enableTutorial: new Rox.Flag(),
  titleColors: new Rox.RoxString('White', ['White', 'Blue', 'Green', 'Yellow']),
  titleSize: new Rox.RoxNumber(12, [14, 18, 24])
};

async function initRollout() {
  const options = { };

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

  // Setup the key
  await Rox.setup('<ROLLOUT-ENV-KEY>', options);

  // Boolean flag example
  if (flags.enableTutorial.isEnabled()) {
    console.log('enableTutorial flag is true');
    // TODO:  Put your code here that needs to be gated
  }

  // RoxString flag example
  console.log('Title color is ' + flags.titleColors.getValue());

  // RoxNumber flag example
  console.log('Title size is ' + flags.titleSize.getValue());
}

initRollout().then(function() {
  console.log('Done loading Rollout');
});

const Rox = require('rox-node');

const flags = {
  enableTutorial: new Rox.Flag(),
  titleColors: new Rox.RoxString('White', ['White', 'Blue', 'Green', 'Yellow']),
  titleSize: new Rox.RoxNumber(12, [14, 18, 24])
};

async function initRollout() {
  const options = { };

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

  // Setup the key
  await Rox.setup('<ROLLOUT-ENV-KEY>', options);

  // Boolean flag example
  if (flags.enableTutorial.isEnabled()) {
    console.log('enableTutorial flag is true');
    // TODO:  Put your code here that needs to be gated
  }

  // RoxString flag example
  console.log('Title color is ' + flags.titleColors.getValue());

  // RoxNumber flag example
  console.log('Title size is ' + flags.titleSize.getValue());
}

initRollout().then(function() {
  console.log('Done loading Rollout');
});

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 Feature Management dashboard after running the application.
