React refresh and null module to Hash.update

[charlessolar]

Toying around with a webpack 5 upgrade and just finished figuring out a small error message I was receiving when doing

yarn start

with this project.

Heres the error:

yarn run v1.22.5
$ webpack --env mode=dev --env isDevServer --env NODE_ENV=local serve --config webpack.config.babel.js

Traced the issue to react-refresh-webpack-plugin https://github.com/pmmmwh/react-refresh-webpack-plugin/issues/289

To fix simply add the webpack.HotModuleReplacementPlugin to the list of plugins in dev.js as the dev suggests. I assume in a future version this won't be an issue any longer.

/**

import ReactRefreshWebpackPlugin from '@pmmmwh/react-refresh-webpack-plugin';

import { HotModuleReplacementPlugin } from 'webpack';

import {devServerConfig} from './config';

export default {
    devtool: 'cheap-module-source-map',
    plugins: [new HotModuleReplacementPlugin(), new ReactRefreshWebpackPlugin()],
    devServer: devServerConfig,
};

Cheers
