module.exports = {
  lintOnSave: false,
  assetsDir: './',
  devServer: {
    hot: true,//自动保存
    port: '9090',
    open: true,
    overlay: {
      warnings: false,
      errors: true
    },
    proxy: {
      "/vp": {
        target: process.env.VUE_APP_REQUEST_URL,
        secure: false,
        ws: true,
        changeOrigin: true,
        headers: {
          Referer: process.env.VUE_APP_REQUEST_URL
        }
      }
    }
  },
