javascript - React - 无限循环 xhr sockjs-node

Question

我从未使用react.js (Create-React-App) 托管过网站。

我已经把这个网站放到网上了，但是我还没有打开API。

我不知道为什么我会像这样自动循环 xhr socketjs-nodes:

即使我只使用 React.js 输入了 1 个项目，物理内存使用量几乎达到 600MB，这都是因为这个 xhr 吗？

这是我的 package.json :

这很可能是webpack-dev-server的请求(也许 hot module replacement 功能已启用，不确定，也许是其他原因)。如果我没记错的话，Create-React-App 在开发模式下使用它(抱歉，没有经常使用它)。所以我相信这很好，但不确定这 600MB 的内存使用是否与此相关。

我的个人旁注:我总是发现像 Create-React-Apps 这样的引导工具对于初学者来说是一件坏事，因为很难理解幕后发生的事情。我的建议 - 要么深入研究 create-react-app 在底层使用什么来更好地理解堆栈，要么从头开始创建你的 React 应用程序，这一点也不难，而且在我看来更好。您可能只需要 node + webpack + react
