Redux middleware for React Native for Flipper

Redux Flipper

Redux middleware for Flipper. It can log redux actions and show inside Flipper using flipper-plugin-redux-debugger.

Support

• React Native
  • For react-native >= 0.62, flippler support is enabled by default
  • For react-native < 0.62, follow these steps to setup your app
• Redux or Redux-Toolkit

Get Started

1. Install redux-flipper middleware and react-native-flipper in your React Native app:

yarn add redux-flipper react-native-flipper
# for iOS
cd ios && pod install

2. Add the middleware into your redux store:

import { createStore, applyMiddleware } from 'redux';

const middlewares = [/* other middlewares */];

if (__DEV__) {
  const createDebugger = require('redux-flipper').default;
  middlewares.push(createDebugger());
}

const store = createStore(RootReducer, applyMiddleware(...middlewares));

3. Install flipper-plugin-redux-debugger in Flipper desktop client:

Manage Plugins > Install Plugins > search "redux-debugger" > Install

4. Start your app, then you should be able to see Redux Debugger on your Flipper app

Optional Configuration

Resolve cyclic reference

Redux Debugger does not support cyclic reference objects by default as resolving it makes application slow. This feature can be enabled by passing { resolveCyclic: true } into createDebugger.

This is just a temporary solution if debugging is urgent. It is advisable to restructure your redux state structure.

For more information about cyclic reference, visit MDN Cyclic Object.

let reduxDebugger = createDebugger({ resolveCyclic: true });

Actions Blacklist

You may specify an actions blacklist the same way as with React Native Debugger, by providing an array of strings to match against the action.type field. This feature can be enabled by passing { actionsBlacklist } into createDebugger, where actionsBlacklist is an array of strings.

For example:

const actionsBlackList = ['EVENTS/', 'LOCAL/setClock'];
const reduxDebugger = createDebugger({ actionsBlackList });

This will exclude any actions that contain the substrings in the blacklist. So an action with type EVENTS/foo will not be sent to the redux debugger flipper plugin, but an action with type LOCAL/anotherAction will.
