## What it is
A Node.js native addon (C++/JNI bridge) that lets JavaScript code call Java classes and APIs directly from Node. It provides a bridge API for interacting with existing Java libraries from the Node.js runtime.

## Use cases
- call java libraries from node.js
- bridge node and jvm code
- use existing java apis in javascript
- invoke java classes from node
- integrate legacy java code with node app

## When to choose
- you need to call Java code from Node.js without running a separate JVM service
- you want direct JNI-level interop with existing Java libraries

## When to avoid
- you prefer decoupled integration via HTTP or message queues instead of in-process JNI
- your build environment cannot compile native addons or lacks a full JDK

## Facets
- artifact type: library
- maturity: maintenance
- function: sdk, developer-tools
- domain: developer-tools, cross-platform
- platform: windows, cross-platform
- tags: java-bridge, jni, nodejs-addon, interop, nodejs, linux, macos
