记录一个问题：webpack 配置plugins的另外一种方式

module.exports = vuxLoader.merge(webpackConfig, {
  plugins: [
      {
          // 自动替换页面路由
          name: 'js-parser',
          test: /main\.js/,
          fn: function (source) {
              let list = fs.readFileSync(pagesPath, 'utf-8')
              list = JSON.parse(list)
              let str = []
              for (var page in list) {
                  let filename = page
                  let path = `/${toDash(page)}`
                  if (/#/.test(page)) {
                      filename = page.split('#')[0]
                      path = page.split('#')[1]
                  }
                  str.push(`{
                    path: '${path}',
                    meta: {title: '${list[page]}'},
                    component: function (resolve) {
                      require(['./pages/${filename}.vue'], resolve)
                    }
                  }`)
              }
              // 404 page
              str.push(`{
                path: '*',
                component: function (resolve) {
                  require(['./components/NotFoundComponent.vue'], resolve)
                }
              }`)
              str = `[${str.join(',\n')}]`
              source = source.replace('let routes = []', 'let routes = ' + str)
              return source
          }
      },
    'vux-ui',
    'inline-manifest',
    'progress-bar',
    'duplicate-style',  {
      // 主题个性化
      name: 'less-theme',
      path: 'src/assets/less/theme.less'
    }
  ]
})
