index.html webpack compiled in reference to the relationship between resource path assetsRoot, assetsSubDirectory, assetsPublicPath of
the figure, as the path generated by a combination of static resources and assetsSubDirectory assetRoot made, i.e. patch.resolve (_dirname, '.. / dist / static1 / static1 / static2')

Generated as above configuration index.html
Wherein the front half of the path by adding assetsSubDirectory composition assetsPublicPath
Determining the path of the first general configuration index, and static path set storage location, final adjustment of the position reference assetsPublicPath
