r2n - Rust to npm

A library for rapidly shipping Rust projects to npm.

This library provides programmatic APIs for:

• Initializing new Rust projects configured for npm
• Building cross-platform binaries, NAPI modules, and WASM packages
• Managing monorepo workspaces (npm and Cargo)
• Publishing to npm with various distribution strategies

Usage

use r2n::{InitProject, InitOptions, PackageType};

let options = InitOptions {
    name: "my-tool".into(),
    package_type: PackageType::Cli,
    ..Default::default()
};

let project = InitProject::new(options)?;
project.create()?;

r2n

Ship Rust CLI tools to npm.

⚠️ EXPERIMENTAL: This package is experimental and should not be used in production. APIs and behavior may change without notice.

Install

cargo install r2n

Usage

Create a new project

r2n init my-tool
cd my-tool

Add to existing Rust project

cd my-rust-project
r2n add

Build

r2n build

This cross-compiles your Rust binary and creates an npm package ready to publish.

What it does

1. Creates package.json with proper bin configuration
2. Generates a Node.js wrapper script
3. Cross-compiles your Rust binary for multiple platforms
4. Outputs to dist/ ready for npm publish
