How do Node.js Native Addons (N-API / Node-API) execute C++/Rust binaries directly?
❓ Interview Prompt: Explain Node-API (N-API) C++ and Rust bindings, ABI stability across Node versions, zero-overhead native execution, and `napi-rs`.
Node-API (N-API) is a native C/C++ API that allows compiling C++ or Rust code into binary '.node' addons loadable via 'require()':
Key Advantage:
•
ABI Stability: N-API provides Application Binary Interface stability; native addons compiled for Node 16 run on Node 20+ without recompilation!
•
Use Cases: SIMD image processing, cryptographic proofs, and heavy mathematical calculations running at native C/Rust speed (10x faster than JS!).
Code Implementation Example
javascript
// JavaScript loading native compiled Rust/C++ addon via N-API
// import nativeAddon from './build/Release/addon.node';
console.log('N-API provides ABI-stable native C++/Rust execution in Node.js');💡Architecture of Node-API (N-API) native addons.
🎯 Interview Key Takeaway
Use N-API or Rust napi-rs for CPU-heavy tasks to execute native C++/Rust binaries with zero GC overhead.
