Calling C++ from JavaScript

Cpp.js enables you to call C++ functions directly from JavaScript with ease. By compiling C++ into WebAssembly for web applications or native code for mobile, it allows seamless integration between the two languages, combining the power and performance of C++ with the flexibility of JavaScript.

The key advantage of Cpp.js is that it automatically handles the binding process, so you can focus on writing your application logic. C++ classes and functions can be used in JavaScript as if they were native objects, with no manual bindings required.

For more detailed information on how to use C++ with JavaScript, refer to the API/C++ Bindings section.

• Functions
• Classes and Objects

Here is a minimal example:

/src/main.js

import { initCppJs } './native/helloWorld.h';

const { getHelloWorldMessage } = await initCppJs();
console.log(getHelloWorldMessage());

/src/native/helloWorld.h

std::string getHelloWorldMessage() {
  return 'Hello World!';
}
