记一次令人头疼的vue多页面分包问题！直接给出分包配置。

webpack相关配置

下面的splitchunks.maxsize会导致build出来的html文件中，没有<script>标签来引用生成的bound.js，打开页面显示空白;去掉maxSize重新build后，能正常显示页面内容。

// config.build.js
optimization: {
        splitChunks: {
          chunks: "all", // initial(初始块)、async(按需加载块)、all(默认，全部块)
          minSize: 30000, // 提取出的新chunk在两次压缩(打包压缩和服务器压缩)之前要大于30kb
          maxSize: 480000,
          cacheGroups: {
            vuetify: {
              test(module) {
                let path = module.resource;
                if (!path) return false;
                path = path.replace(/\\/g, "/");
                return path && /node_modules\/vuetify\//.test(path);
              },
              name: "chunk-vuetify",
              priority: 18,
              // enforce: true,
            },
            vendors: {
              test(module) {
                let path = module.resource;
                if (!path) return true;
                path = path.replace(/\\/g, "/");
                let isNeed = path && /node_modules/.test(path);
                return isNeed;
              },
              name: "chunk-vendors",
              priority: 3,
              chunks: "initial",
              // enforce: true,
            },
            common: {
              name: "chunk-common",
              minChunks: 2,
              minSize: 30000,
              reuseExistingChunk: true,
            },
          },
        },
      },

使用maxsize build出来的文件展示

</html>

可以看到上面没有script标签来引用index~3364b0b4.08b2434b.js文件

将maxsize注释掉之后的build出来的html文件展示
