Question

我使用 vue create project-name 初始化了新的vue.js项目打开“网络”选项卡时，尽管页面和系统上没有任何更改，但我看到系统连续（如此快）发送请求。

我检查了我之前创建的其他vue.js项目，没有这种情况。为什么会这样，这是否有害？

（我无法添加此图像，如果您进行编辑，我将不胜感激）

edit：另外我还意识到，当我更改某些内容时，通常vue会立即进行自我更新。现在没有。刷新页面后，可以看到更改。

edit2：我尝试创建2个vue.js项目。您可以看到package.json文件。

如果它是一个websocket，那就不奇怪了。它将每X毫秒连续轮询一次。如果使用socket.io之类的库，您将看到相同的行为。这是一种轮询架构。
