Javascript communicate with C++
提问by Rob
I have a desktop application that has a C++ backend and a HTML5/JS front end. We are currently having to use Google V8 or Mac Webview and Objective-C to allow Javascript and C++ to communicate. Is there any way to have them directly talk to each other without the middleware?
我有一个桌面应用程序，它有一个 C++ 后端和一个 HTML5/JS 前端。我们目前不得不使用 Google V8 或 Mac Webview 和 Objective-C 来允许 Javascript 和 C++ 进行通信。有没有办法让他们在没有中间件的情况下直接相互交谈？
Trying to accomplish:
试图实现：
- Share variables.
- Call Functions from C++ to JS.
- Call Functions from JS to C++.
- 共享变量。
- 从 C++ 调用函数到 JS。
- 将函数从 JS 调用到 C++。
I have tried googling this and everything points to the above solutions.
我试过谷歌搜索这个，一切都指向上述解决方案。

You could try using Google's Protocol Bufferswhich allows you to create data objects that get compiled to C++ objects. You could then use one of the following projects from their wikito use protobuffers with javascript:
您可以尝试使用 Google 的Protocol Buffers，它允许您创建编译为 C++ 对象的数据对象。然后，您可以使用他们wiki中的以下项目之一来将 protobuffers 与 javascript 一起使用：

Your software sounds like a lot like a web app, without the internet in the middle. NodeJSmight make good middleware in this case, you can write modulesfor it in C++, and use them in javascript. I haven't done this yet myself. A short example:)
你的软件听起来很像一个网络应用程序，中间没有互联网。在这种情况下，NodeJS可能是很好的中间件，你可以用C++ 为它编写模块，然后在 javascript 中使用它们。我自己还没有这样做。一个简短的例子:)
And now a few years layerwe have the Electron project, which is basically the above but with a Chrome based web view.
现在几年我们有了Electron 项目，它基本上是上面的，但是有一个基于 Chrome 的 web 视图。

You can now use Electronto get basically a Chrome web browser with direct access to the Node.js API. Then you can use nbindto easily call C++ code from JavaScript. This way both share the same thread and heap.
你现在可以使用Electron来获得基本的 Chrome 网络浏览器，它可以直接访问 Node.js API。然后您可以使用nbind从 JavaScript 轻松调用 C++ 代码。这样两者共享相同的线程和堆。
You declare the C++ classes by adding something like this to a C++11 source file:
您可以通过向 C++11 源文件中添加以下内容来声明 C++ 类：
NBIND_CLASS(X) {
construct<int, int>();
method(Y);
method(Z);
}
That creates bindings for a class X with a constructor taking 2 ints and methods Y and Z with pretty much any kind of arguments and optional return values.
这为类 X 创建了绑定，其构造函数采用 2 个整数，方法 Y 和 Z 具有几乎任何类型的参数和可选的返回值。
nbindcomes with an example for how to package your C++ code into a Node.js addon, for use in Electron.
nbind附带一个示例，说明如何将您的 C++ 代码打包到 Node.js 插件中，以便在 Electron 中使用。

libjspp allows easy interfacing & interacting of C++ with javascript spidermonkey 1.8.5? Non intrusive to C++ & javascript world at same time. Useful for applications which want to Embed & Extend Javascript in object oriented manner. Very thin interface virtually no overhead by using C++ templates.
libjspp 允许 C++ 与 javascript spidermonkey 1.8.5 轻松接口和交互？同时不侵入 C++ 和 javascript 世界。对于想要以面向对象的方式嵌入和扩展 Javascript 的应用程序很有用。通过使用 C++ 模板，非常薄的界面几乎没有开销。
