[FIXED] I didn’t define the path into my webpack.config.js, so with this
output: {
path: './js/shop/',
filename: 'build.js'
},
It works
But now I have issue with handling .svg files, basically it output this as the source of SVG icon
<img src="[object" object]="" alt="icon" class="svg-icon">
[FIXED] svg-url-loader did the trick.
