Logger with handler

// logger.js

import { Logger, Handler } from 'react-native-pluggable-logger';

// create some logging handler
const consoleHandler = new Handler.ConsoleHandler();
const nullHandler = new Handler.NullHandler();
const httpHandler = new Handler.HttpHandler('http://myLogUrl.io');

// create a logger with handler
const myLogger = new Logger(consoleHandler);
myLogger.info('just an info'); // logged to console
// use null handler for do not displaying this logs
myLogger.setHandler(nullHandler);
myLogger.info('just an info');
// use http handler for sending logs to an url
myLogger.setHandler(httpHandler);
myLogger.info('just an info'); // sent to url

export default myLogger;

redux integration

// store.js

import {
  applyMiddleware,
  compose,
  createStore,
} from 'redux';
import { createReduxActionLoggerMiddleware, reduxLogger } from 'react-native-pluggable-logger';
import customerActionTypes from './ActionTypes/orders';

const reduxActionLoggerMiddleware = createReduxActionLoggerMiddleware({
  removeStatesFromLog: ['login'],
  actionTypesToLog: [
    customerActionTypes.CREATE_CUSTOMER,
  ],
});

const middleware = compose(applyMiddleware(
  // ... more middlewares
  reduxActionLoggerMiddleware,
));

const reducers = combineReducers({
  // ... more reducers
  reduxLogger,
});

export function configureStore(initialState = {}) {
  const store = createStore(
    reducers,
    initialState,
    middleware,
  );
  return { store };
}

export const { store } = configureStore();

import App from './App.react';
import logger from './logger';
import store from './store';

const AppWithLogger = withReduxLogger(store, logger, true)(App);

export default function index() {
  class MyApp extends Component {
    render() {
      return (
        <Provider store={store}>
          <AppWithLogger />
        </Provider>
      );
    }
  }
  AppRegistry.registerComponent('MyApp', () => MyApp);
}
