Overview

Integrate code written in different programming languages to leverage their unique strengths and ecosystems.

When to Use

• Performance-critical code in C/C++/Rust
• ML models in Python from other languages
• Legacy system integration
• Leveraging language-specific libraries
• Microservices polyglot architecture

Quick Start

Minimal working example:

// addon.cc
#include <node.h>

namespace demo {

using v8::FunctionCallbackInfo;
using v8::Isolate;
using v8::Local;
using v8::Object;
using v8::String;
using v8::Value;
using v8::Number;

void Add(const FunctionCallbackInfo<Value>& args) {
  Isolate* isolate = args.GetIsolate();

  if (args.Length() < 2) {
    isolate->ThrowException(v8::Exception::TypeError(
        String::NewFromUtf8(isolate, "Wrong number of arguments")));
    return;
  }

  if (!args[0]->IsNumber() || !args[1]->IsNumber()) {
    isolate->ThrowException(v8::Exception::TypeError(
        String::NewFromUtf8(isolate, "Arguments must be numbers")));
// ... (see reference guides for full implementation)

Best Practices

✅ DO

• Use appropriate IPC mechanism
• Handle serialization carefully
• Implement proper error handling
• Consider performance overhead
• Use type-safe interfaces
• Document integration points

❌ DON'T

• Pass complex objects across boundaries
• Ignore memory management
• Skip error handling
• Use blocking calls in async code
