module.exports = {
  // publicPath: process.env.NODE_ENV === 'production'?'/':'/',
  // i18n
  chainWebpack: config => {
    config.module
      .rule('i18n')
      .resourceQuery(/blockType=i18n/)
      .type('javascript/auto')
      .use('i18n')
      .loader('@kazupon/vue-i18n-loader')

      .set('components', resolve('src/components'))
      .set('views', resolve('src/views'))
      .set('utils', resolve('src/utils'))
