I use babel-eslint to lint/fix my code. Worked great until I wanted to adopt some ES2017 async await found overhere.
I changed my React app accordingly, allbeit slightly different:
The relevant part of my index.js:
async function renderApp() { const store = await configureStore() const history = syncHistoryWithStore(browserHistory, store, { selectLocationState: state => state.get('routing') }) ReactDOM.render( <AppContainer> <MuiThemeProvider muiTheme={muiTheme}> <Provider store={store}> <Router history={history} routes={routes(store)} /> </Provider> </MuiThemeProvider> </AppContainer>, document.getElementById('root') ) } renderApp() My store:
// @flow import 'babel-polyfill' import { addFormSubmitSagaTo } from 'redux-form-submit-saga/es/immutable' import { applyMiddleware, createStore, compose } from 'redux' import { autoRehydrate, persistStore } from 'redux-persist-immutable' import { browserHistory } from 'react-router' import { combineReducers } from 'redux-immutable' import { fromJS } from 'immutable' import { routerMiddleware } from 'react-router-redux' import createSagaMiddleware from 'redux-saga' import rootReducer from './rootReducer' import sagas from './rootSaga' export default function configureStore() { return new Promise((resolve, reject) => { try { const sagaMiddleware = createSagaMiddleware() const middleware = [ routerMiddleware(browserHistory), sagaMiddleware ] const enhancer = compose( autoRehydrate(), applyMiddleware(...middleware) ) const store = createStore( combineReducers(rootReducer), undefined, enhancer ) // Decorate with Redux Form Submit Saga // and create hook for saga's const rootSaga = addFormSubmitSagaTo(sagas) sagaMiddleware.run(rootSaga) // Persist store to the local storage persistStore( store, { whitelist: ['auth', 'timezone'] }, () => resolve(store) ) } catch (e) { reject(e) } }) } Here's my .eslintrc:
{ "env": { "browser": true, "jest/globals": true }, "extends": [ "standard", "standard-flow", "plugin:react/recommended" ], "plugins": [ "compat", "jest", "react" ], "parserOptions": { "ecmaVersion": 2017, "sourceType": "module", "ecmaFeatures": { "jsx": true } }, "rules": { "comma-dangle": ["warn", "only-multiline"], "compat/compat": 2, "jest/no-disabled-tests": "warn", "jest/no-focused-tests": "error", "jest/no-identical-title": "error", "max-len": ["warn", 80], "no-debugger": 0, "react/jsx-uses-vars": [2] } } Here's my .babelrc:
{ "plugins": [ "react-hot-loader/babel", "syntax-flow", "tcomb", "transform-class-properties" ], "presets": [ "es2015", "react", ["env", { "targets": { "browsers": ["last 2 versions"] } }] ] } But whatever I do: I keep getting the following error:

I came accross multiple posts with similar problems, but none of these have lead to an answer until now.
