I am not able to get the HMR with "wp-scripts start –hot" running. I tried this in several project, including rather empty projects.
As soon as I add the –hot flag to my npm script, I can still get the script running but I get this error message in my console:
ReactRefreshEntry.js:17 Uncaught TypeError: Cannot read properties of undefined (reading 'injectIntoGlobalHook')
at ./node_modules/@pmmmwh/react-refresh-webpack-plugin/client/ReactRefreshEntry.js (ReactRefreshEntry.js:17:1)
at options.factory (react refresh:6:1)
at __webpack_require__ (bootstrap:24:1)
at startup:4:66
at __webpack_require__.O (chunk loaded:25:1)
at startup:9:1

It doesn’t even load my Javascript as it seems to break at an earlier point.
I already changed Node Versions back and forth, deleted all node-modules and the package-lock.json, took out all my Javascript to see if this solves anything, but it doesn’t.
My setup:
Local by Flyhweel as WordPress local environment
Wordpress: 6.0.3
Node V 16.18.0
npm 8.19.2
@wordpress/scripts Version: 24.4.0
wp-config.php:
define('WP_DEBUG', false); define('SCRIPT_DEBUG', true);
Also I got the Gutenberg Plugin installed and activated as stated here: https://developer.wordpress.org/block-editor/reference-guides/packages/packages-scripts/#:~:text=%2D%2Dhot%20%E2%80%93%20enables%20%E2%80%9CFast%20Refresh%E2%80%9D.%20The%20page%20will%20automatically%20reload%20if%20you%20make%20changes%20to%20the%20code.%20For%20now%2C%20it%20requires%20that%20WordPress%20has%20the%20SCRIPT_DEBUG%20flag%20enabled%20and%20the%20Gutenberg%20plugin%20installed.
Does anyone else experience this bug or can anyone help with this?
Many thanks and cheers

I could not get
react-refresh-webpack-plugin
to work in @worpress/script so ended up usingBrowserSyncPlugin
, here is how i extended the @wordpress/script webpack config. Hope it helps someoneand
yarn run start
Disclaimer: Am developing in docker env. i know its not answer to the question, but if you are stuck, kindly try it out.
I faced same issue and fix is easy. As stated here, you need to set SCRIPT_DEBUG flag: https://github.com/WordPress/gutenberg/tree/trunk/packages/scripts#start
Add in the wp-config.php
