Java Addon V8

This report analyzes the architecture, benefits, and implementation strategies for embedding the Google V8 JavaScript engine within a Java environment. While Java provides its own scripting API (Nashorn/GraalVM), integrating the native V8 engine allows Java applications to execute modern JavaScript (ES6+) at near-native speeds. This approach is critical for applications requiring high-throughput data processing, server-side rendering of modern web frameworks, or logic portability between front-end and back-end systems.

// Initialize V8 instance
V8 v8 = V8.createV8Runtime();
// Execute simple script
int result = v8.executeIntegerScript("const x = 10; const y = 20; x + y;");
System.out.println("Result: " + result); // Output: 30
// Bridge Java objects to JS
V8Object javaObject = new V8Object(v8);
javaObject.add("name", "Report Generator");
v8.add("javaContext", javaObject);
// Execute JS interacting with Java object
String output = v8.executeStringScript("javaContext.name + ' Complete';");
System.out.println(output); // Output: Report Generator Complete
// Critical: Release resources
javaObject.release();
v8.release();
