在 NodeJS 中不使用换行符进行日志记录

Question

How to log this stream of data without a newline each time?如何在每次没有换行符的情况下记录此 stream 数据？

websocket.on('message', (msg) => {
    console.log(msg.content);
  }
});

Above would result in:以上将导致：

> streamedContent-1
> streamedContent-2
> streamedContent-3..

What I want to achieve is:我想要实现的是：

> streamedContent-n // this line getting updated on each refresh, no new line

You can use c++ stdout methods inside a Node app to "edit" a line in runtime.您可以在 Node 应用程序中使用 c++ stdout方法在运行时“编辑”一行。

process.stdout.clearLine()
process.stdout.write(`\r${msg.content}`);
