## What it is
Neon is a Rust library and toolchain for writing safe, fast native Node.js addons using Node-API. It provides memory-safe bindings so Rust code can be embedded in Node.js applications and libraries.

## Use cases
- write node.js native addons in rust
- speed up slow javascript hot paths with rust
- use rust crates from node.js
- run multithreaded parallel code in node safely
- call native os libraries from node.js
- build a node module with rust instead of c++

## When to choose
- you need raw performance beyond what javascript can offer
- you want memory-safe native addons guaranteed by the rust compiler
- you need threads and parallelism without data races
- you want access to the rust ecosystem from node.js

## When to avoid
- your workload is not performance-bound and plain javascript suffices
- you need full bun compatibility, which is still experimental
- you want to avoid a rust toolchain dependency in your build

## Facets
- artifact type: library
- maturity: stable
- function: sdk, developer-tools, concurrency
- domain: developer-tools, web-development, backend, cross-platform
- platform: rust, windows, cross-platform
- tags: nodejs-native-addons, rust-bindings, napi, ffi, node-api, native-modules, nodejs, linux, macos
