babel-loader doesn't working, es6 code stay un-compiled

this is my config file

{
    entry: path.resolve(__dirname, '../app/index'),
    output: {
        path: path.resolve(__dirname, '../static/js'),
        publicPath: '/js/',
        filename: 'bundle.js'
    },
    module: {
        rules: [
            {
                test: /\.js$/,
                exclude: /node_modules/,
                use: {
                    loader: 'babel-loader',
                    options: {
                        presets: [
                            'es2015',
                        ]
                    }
                },
            }
        ]
    }
}

this is part of the result

/***/ function(module, exports) {

	import Vue from 'vue';
	import App from './app.vue';

	new Vue({
	    el: '#app',
	    render: h => h(App)
	});


/***/ }

And webpack reports no error.

@soykje test should be a RegEx, but you’ve put quotes around it so it will not match any files. You want test: /\.js$/, without the quotes.

I had the same issue when I updated my build chain… weirdly placing a .babelrc in my folder fixed it…

{
  "presets": [["es2015"]]
}

But it seems weird to need that…
