[Webpack] web-dev-server ne crée pas mon fichier app.js

Bonsoir,

Je suis la formation webpack et jusqu'à l'instalation de webpack-dev-server tout ce passait bien. En lançant la cmd "cross-env NODE_ENV=dev webpack", mes fichiers étaient bien compilés et créés dans mon dossier "dist" tant en production qu'en développement .

Une fois webpack-dev-server installé et en exécutant la cmd "cross-env NODE_ENV=dev webpack-dev-server --open" la console me dit que mon fichier app.js est bien émit mais en réalité dans mon projet je ne trouve aucun fichier.

Voici ce que me dit la console

npm run start

> project-starter@1.0.0 start D:\Sites\Lab\project-starter
> cross-env NODE_ENV=dev webpack-dev-server --open

webpack: Compiled successfully.

Et voici mon fichier webpack.config.js

const CleanWebpackPlugin = require('clean-webpack-plugin');
const webpack = require("webpack");
const path = require("path");
const uglifyJSPlugin = require('uglifyjs-webpack-plugin');
const ExtractTextPlugin = require("extract-text-webpack-plugin");

let isDev = process.env.NODE_ENV === "dev"; //return false or true
let cssDev = ['style-loader', 'css-loader', 'sass-loader', 'postcss-loader'];
let cssProd = ExtractTextPlugin.extract({
    fallback: 'style-loader',
    use: [{loader: 'css-loader', options: {minimize: false}}, 'sass-loader', 'postcss-loader']
});
let devPath = './dist/';
let prodPath = './';

let cssConfig = isDev ? cssDev : cssProd;
let publicPathConfig = isDev ? devPath : prodPath;

let config = {

        app: ['./assets/scss/app.scss', './assets/js/app.js']
    },
    watch: isDev,
    output: {

        filename: "./[name][hash:8].js",

                }]
            }
        ]
    },
    devtool: isDev ? "cheap-module-eval-source-map" : false,
    plugins: [
        new ExtractTextPlugin({
            filename: '[name].css',
            disable: isDev
        })

    ]
}
if (!isDev){
    config.plugins.push(new uglifyJSPlugin({
        sourceMap: false
    })),
    config.plugins.push(new CleanWebpackPlugin(['dist'], {
        root: path.resolve('./'),
        verbose: true,
        dry: false
    }))
}
module.exports = config;

J'utilise webpack 3.11.0 et webpack-dev-server 2.11.1

Merci d'avance pour votre aide
