Nodejs communicate with C++ program?
提问by Nami WANG
Say I've got a c++ program running on the same server with a Node.js web app, on a linux server.
假设我有一个 C++ 程序与 Node.js Web 应用程序在同一台服务器上运行，在 linux 服务器上。
The c++ program maintains a queue, and what I want to do with Node.js is, push some data into the queue.
c++程序维护了一个队列，我想用Node.js做的是，把一些数据推入队列。
What's the best way to do this?
做到这一点的最佳方法是什么？
Which is better? sockets or IPC?
哪个更好？插座还是工控机？

If you're using Linux, I would suggest UNIX-domain sockets. They basically give you the high-performance of IPC using the BSD socket interface, making it easy to switch for TCP sockets later if you need to move the C++ (or node.js) application to a different computer.
如果您使用的是 Linux，我建议您使用UNIX-domain sockets。它们基本上为您提供了使用 BSD 套接字接口的 IPC 的高性能，如果您需要将 C++（或 node.js）应用程序移动到另一台计算机，则稍后可以轻松切换到 TCP 套接字。
They're already supported by node.jsand only the code that opens the socket will need to be changed. Many applications, including MySQL easily abstract this away in a configuration file.
node.js 已经支持它们，只需要更改打开套接字的代码。许多应用程序，包括 MySQL，很容易在配置文件中抽象出来。

I'd use sockets, they are clean and easy to use
我会使用插座，它们干净且易于使用

If you want to use an IPC mechanism, you may consider writing a Node.js C++ module, and then use something from the Boost.Interprocesslibrary to communicate with your other app.
如果你想使用 IPC 机制，你可以考虑编写一个Node.js C++ 模块，然后使用Boost.Interprocess库中的东西与你的其他应用程序通信。
Boost.Interprocess has mechanisms already build for sharing containers from the standard library. Its also cross platform if you want to be open to that in the future.
Boost.Interprocess 已经构建了用于从标准库共享容器的机制。如果你想在未来开放，它也是跨平台的。
