Package Exports

ld-redux

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (ld-redux) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

ld-redux

A library to integrate launch darkly feature toggles with react redux

Documentation coming soon

Quickstart:

You'll need redux-thunk and set it up as middleware when creating your redux store:

import { createStore, applyMiddleware } from 'redux';
import thunk from 'redux-thunk';
import reducers from '../reducer';

export default function() {
  const store = createStore(reducers, applyMiddleware(thunk));
  return store;
};

In your client bootstrap:

import {initLD} from 'ld-redux';
const store = createStore();
initLD('57d3a57f53f8630721228f2d', store);

In your main reducer file:

import {ldReducer} from 'ld-redux';

export default combineReducers({
  yourReducer1,
  yourReducer2,
  LD: ldReducer,
});

Then in a redux container:

import {getFlagsFromState, mapActionsToProps, ldConnect} from 'ld-redux';

// These must be the keys you set up in launch darkly dashboard (kebab-lower-cased)
const defaultFlags = {'random-number': false};

const mapStateToProps = (state) => {
  // this is your own state
  const homeState = state.Home;

  // Use helper method to subscribe to your flags as camelCased props
  const flags = getFlagsFromState(state, defaultFlags);

  return {
    someRandomNumber: homeState.someRandomNumber,
    ...flags,
  };
};

// Use helper method to create mapDispatchToProps, passing your actions to the helper method
@connect(mapStateToProps, mapActionsToProps(homeActions))
@ldConnect(defaultFlags) // connect the component to the feature flags it needs
export default class HomeContainer extends Component {
  render() {
    return <HomeComponent {...this.props} />;
  }
};
