Webpack dev – server issue official link:
https://github.com/webpack/webpack-dev-server/issues/2759
webpack-dev-server update version, the command line changed from
webpack dev serve to webpack serve
, so the package.json needs to be changed to:
"scripts": {
"dev": "webpack serve --mode development"
}
See the dead simple Readme:
