How to properly set up material-ui with electron-react-boilerplate


I'm having issues with material-ui (v4.9.5) library running with electron-react-boilerplate. To reproduce:

  1. follow the installation tutorial
  2. yarn add @material-ui/core
  3. add some widgets from the library:
diff --git a/app/components/Home.tsx b/app/components/Home.tsx
index 20748ab..f4f9a21 100644
--- a/app/components/Home.tsx
+++ b/app/components/Home.tsx
@@ -1,11 +1,13 @@
 import React from 'react';
 import { Link } from 'react-router-dom';
+import { Button } from '@material-ui/core';
 import routes from '../constants/routes.json';
 import styles from './Home.css';

 export default function Home() {
   return (
     <div className={styles.container} data-tid="container">
+      <Button>Hello</Button>
       <h2>Home</h2>
       <Link to={routes.COUNTER}>to Counter</Link>
     </div>

Now everything works great when you run yarn dev. However, yarn start produces:

Is there any way to fix this?


Solution

  • It seems that removal of these lines from the main.dev.ts file solves the problem:
