## README

# CloudBees Feature Management - Browser SDK 🦆

CloudBees Feature Management is a secure feature management solution for the enterprise.

> Accelerate development and minimize the risk of deploying new code with simple to create feature flags, controlled rollouts, advanced target groups & deployment rules.

## Getting Started

Please see the detailed instructions in our docs on how to [add CloudBees Feature Management to your project](https://docs.cloudbees.com/docs/cloudbees-feature-management/).

## Documentation

Getting started guide, use cases, examples and videos can be found at [CloudBees Feature Management documentation](https://docs.cloudbees.com/docs/cloudbees-feature-management/).

## About

CloudBees Feature Management JavaScript SDK for web applications. Define and use simple and advanced feature flags, remote configuration variables, static and computed custom properties in code. Control your application features via CloudBees Feature Management dashboard.

## Installation
```
npm i rox-browser --save
```

## TypeScript Support

This package includes TypeScript definitions. Import and use with full type safety:

```typescript
import Rox from 'rox-browser';
```

## Usage
Obtain an application key by registering at [CloudBees Unify](https://cloudbees.io). 

```javascript
import Rox from 'rox-browser';

const appSettingsContainer = {
  shouldShowWelcome: new Rox.Flag(),
  textColor: new Rox.RoxString('black'),
  textSize: new Rox.RoxNumber(12, [18, 24])
};

const onRoxReady = () => {
  if (appSettingsContainer.shouldShowWelcome.isEnabled()) {
    const color =  appSettingsContainer.textColor.getValue()
    const size =  appSettingsContainer.textSize.getValue()
    const div = document
      .createElement('div')
      .textContent('Hello world!')
      .setAttribute('style', `color: ${color}; font-size: ${size}px`);

    const body = document.getElementsByTagName('body')[0]
    body.appendChild(div)
  }
};

Rox.register('settingsNamespace', appSettingsContainer);
Rox.setup('<app key>', {
  configurationFetchedHandler: onRoxReady
});
```
## Configure the SDK with different options
Override the default configuration by providing predefined configuration preset for `Rox.setup`.

For example:
```javascript
import Rox from 'rox-browser';

/*
- roxOptions.distinctId
- roxOptions.version
- roxOptions.configurationFetchedHandler
*/

const roxOptions = {
  distinctId: 'sessionDistinctId',
  version: '1.0',
  configurationFetchedHandler: () => {}
};

Rox.setup('<app key>', roxOptions);
```

## Activating Manual Overrides UI

You can override flags manually using a built-in UI debug utility that can be activated by invoking `Rox.showOverrides()`.

Running it will display a UI element that allows to explicitly set values of flags.
Available UI location of the UI element:
- `'top left'`
- `'top right'`
- `'bottom left'`
- `'bottom right' (default)`
