node.js - 如何用nodejs监听ip里面的数据包

Question

想做一个流量监听的桌面应用
想监听本机ip流过的所有数据报
或者只是获取一个进程的数据包也可以
例如：chrome里面的network

Answer 1

Native Node does not provide this function, but there is a corresponding module Raw-Socket on NPM

Answer 2

Nodejs cannot reach such a low level. You said you want it to capture web page data, which is fine.

You have to implement this through the system API or even lower-level hooks and drivers.
