Error with Redux DevTools Extension using TS: "Property '__REDUX_DEVTOOLS_EXTENSION_COMPOSE__' does not exist on type 'Window'."?

I'm getting this error on my index.tsx.

Property 'REDUX_DEVTOOLS_EXTENSION_COMPOSE' does not exist on type 'Window'.

Here is my index.tsx code: 

import * as React from 'react';
import * as ReactDOM from 'react-dom';
import App from './App';
import './index.css';
import registerServiceWorker from './registerServiceWorker';

import { Provider } from 'react-redux';

import { createStore, compose, applyMiddleware } from 'redux';
import rootReducer from './store/reducers';

import thunk from 'redux-thunk';

const composeEnhancers = window.__REDUX_DEVTOOLS_EXTENSION_COMPOSE__ || compose;

 const store = createStore(rootReducer, composeEnhancers(
     applyMiddleware(thunk)
 ));

ReactDOM.render(  <Provider store={store}><App /></Provider>, document.getElementById('root'));

registerServiceWorker();

I've installed @types/npm install --save-dev redux-devtools-extension and I'm using create-react-app-typescript. Thanks alot for any tips for what's going on in advance.

Solution

  • This is how you can use redux-dev-tools in a typescript react application.

    Create global Interface for the Window object:

    declare global {
  interface Window {
    __REDUX_DEVTOOLS_EXTENSION_COMPOSE__?: typeof compose;
  }
}

    Then, create composeEnhancers as follows:

    const composeEnhancers = window.__REDUX_DEVTOOLS_EXTENSION_COMPOSE__ || compose;

    Then create a store.

    const store = createStore(rootReducers, composeEnhancers());

    rootReducers - in my case refers to combinedReducers created in a surparate file.

    Now you can use Provider as usual in React.js as:

    ReactDOM.render(
  <React.StrictMode>
    <Provider store={store}>
      <App />
    </Provider>
  </React.StrictMode>,
  document.getElementById("root")
);

    All the code in the index.tsx

    import React from "react";
import ReactDOM from "react-dom";
import "./index.css";
import App from "./App";
import reportWebVitals from "./reportWebVitals";
import rootReducers from "./reducers";

import { Provider } from "react-redux";
import { createStore, compose, applyMiddleware } from "redux";

declare global {
  interface Window {
    __REDUX_DEVTOOLS_EXTENSION_COMPOSE__?: typeof compose;
  }
}

const composeEnhancers = window.__REDUX_DEVTOOLS_EXTENSION_COMPOSE__ || compose;
const store = createStore(rootReducers, composeEnhancers());

ReactDOM.render(
  <React.StrictMode>
    <Provider store={store}>
      <App />
    </Provider>
  </React.StrictMode>,
  document.getElementById("root")
);
reportWebVitals();
