module.exports = {
  devServer: {
    proxy: {
      // 所有 websocket 接口地址加 /websocket 前缀，例：ws://localhost:8080/websocket/dashboard -> wss://notice.app.upall.cn/dashboard

        secure: false,
        logLevel: 'debug',
        pathRewrite: {
          '^/websocket': '' // 把二级目录变成一级目录
        }
      }
