## What it is
NAPI-RS is a Rust framework for building pre-compiled Node.js add-ons via Node-API, with a CLI for zero-config builds, cross-compilation, and CI workflows. It generates low-overhead bindings with TypeScript declarations and supports WASI fallbacks.

## Use cases
- write Node.js native addons in Rust
- build high-performance npm packages with Rust
- cross-compile native Node modules for multiple platforms
- expose Rust functions to JavaScript with #[napi] macros
- ship portable native binaries with WASI fallback

## When to choose
- you need native performance in a Node.js package
- you want ABI-stable addons that work across Node versions
- you need multi-platform prebuilt binaries without node-gyp

## When to avoid
- your addon logic is trivial and pure JavaScript suffices
- you target runtimes without Node-API support
- you need a pure WebAssembly-only module without native builds

## Facets
- artifact type: framework
- maturity: stable
- function: build-tool, cli, wasm, developer-tools
- domain: developer-tools, web-development, cross-platform
- platform: rust, cross-platform, wasm
- tags: node-api, native-addons, napi, rust-bindings, cross-compilation, wasi, nodejs
