react-redux-feature-flags

Feature Flag Component for React/Redux

Purpose

This package works with React and Redux to provide an easy-to-use feature wrapping component.

Installation

Using npm:

  $ npm install --save react-redux-feature-flags

Setup

Add Reducer to Project

To utilize the featureFlagsReducer, you must first import it into your project and combine with your other project reducers using Redux's combineReducers method:

import { combineReducers } from 'redux';
import { featureFlagsReducer } from 'react-redux-feature-flags';
 
import otherReducer from './otherReducer';
 
const rootReducer = combineReducers({
    otherReducer,
    features: featureFlagsReducer,
});
 
export default rootReducer;

Declare Feature Flags

It is recommended that you create a features.js file in the root directory of your project:

  const features = {
    someFeature: true,
    someOtherFeature: false
  }
 
  export default features;

You can then import your features into to your index.js file (example using ES6) and pass them to the dispatchable addFeatureFlags method:

  import { addFeatureFlags } from 'react-redux-feature-flags';
 
  import features from './features';
 
  /***************************
  * Initialize Feature Flags
  ****************************/
  store.dispatch(addFeatureFlags(features));

Treat Component as a Feature

Finally, you can wrap your feature in the Feature component and pass it a flag defined in your features.js. If the flag is truthy, the children of the Feature component will render:

  <Feature flag="someFeature">
    <Link to="/link/will/render" />
  </Feature>
  <Feature flag="someOtherFeature">
    <Link to="/link/will/not/render" />
  </Feature>
