Are there any cross-platform inter-process communication APIs available in both C++ and Javascript?

In the process of developing an app, I am faced with the challenge of passing messages between a C++ application and a Javascript web app.

While I have experience writing sockets code in both languages when required, I am now looking for a higher-level message posting or message queueing API that can simplify the process for me. Does anyone know of such an API?

I have explored options like ICE, but it lacks Javascript bindings. Similarly, Boost message queue only supports C++. If needed, I am willing to create my own Javascript bindings for these technologies.

UPDATE: I forgot to mention earlier that I intend to run this in a browser.

To elaborate on my requirements, I need a user-friendly browser-based application for configuring and displaying logging for a C++ program.

Although there are alternative methods available, my focus is on finding a high-level library that creates a message queue using the sockets API in both C++ and Javascript for browsers.

ALSO: The cross-browser compatibility is not a major concern for me. For instance, if there is a high-level IPC Javascript library exclusive to Chrome, I am willing to work with that restriction.

Answer №1

When working with JavaScript, are you executing it in a web browser? If so, your C++ program will need to establish a webserver and create a JSON-based webservice for communication. You can then use AJAX on the JavaScript side to interact with this webservice.

Another option could be using websockets, although implementing them in C++ may be more challenging.

Answer №2

Can ECMAscript support IPC? The simple answer is no, there is no built-in Inter-Process Communication implemented in ECMAscript.

However, you already provided the solution to your question. When communicating with JavaScript running in a browser, using (web-)sockets connections to transmit data in both directions is the most appropriate approach. While it is possible to create a basic HTTP server in C++, utilizing bi-directional sockets offers more functionality and efficiency.

Although developing a web-socket connection in C++ from scratch requires some effort due to evolving specifications, there are existing libraries that can simplify the process.

If your goal is to interact with node.js, establishing communication via real sockets/pipes is a straightforward task.

Answer №3

After exploring different options, I have discovered a solution that fits my requirements. While it may not be flawless, I believe it serves its purpose adequately.

Following suggestions from others, I decided to incorporate HTTP and ajax into my project. This approach turned out to be quite helpful, and through some trial and error, I found it to be sufficient for the basic needs I have.

More specifically, I am utilizing the Mongoose HTTP server within my C++ application and employing the jQuery ajax function to retrieve data from the server. My jQuery client continuously checks the server for updates, which may not be the most efficient method but should suffice for my purposes.

Once I finalize my implementation, I plan to write a comprehensive article detailing the process for others to follow. I will then make sure to update this answer accordingly.

If you're looking for a straightforward way to define, query, and utilize interfaces, consider exploring DBus. There are handy components available for XPCOM and webkit based browsers that make use of DBus, such as the Browser DBus Bridge (http://sandbox.movial.com/wiki/index.php/Browser_DBus_Bridge) and v8-dbus (http://code.google.com/p/v8-dbus/). Additionally, DBus is an open-source tool that is compatible with multiple platforms.

Answer №5

Have you considered using named pipes for a server-side or non-browser implementation?

While it may be considered vintage technology and its usage depends on the operating system, if your server-side JavaScript environment has the ability to read and write files, named pipes could be a suitable option. It can be viewed as a form of 'high-level' inter-process communication.
