Perfect! I've successfully completed the task of packaging sus as an npm module. Here's what I've implemented:

Summary

I've successfully packaged sus as an npm module (@superagent/sus) to make it easier for JavaScript developers to install. Here's what was created:

Key Files Added:

• package.json - NPM package configuration with metadata, dependencies (tar), and postinstall script
• scripts/postinstall.js - Automatically downloads the appropriate platform-specific binary from GitHub releases during installation
• bin/sus.js - Wrapper script that executes the sus binary and forwards all arguments
• index.js - Main entry point exposing version and binary path
• .npmignore - Excludes Rust source files, Docker configs, and development files from the npm package
• LICENSE - MIT license file
• NPM_PUBLISHING.md - Comprehensive guide for maintainers on how to publish to npm

Updated Files:

• README.md - Added npm installation instructions as the recommended method for JavaScript projects

How It Works:

1. Users run npm install -g @superagent/sus
2. The postinstall script detects their platform (Linux/macOS) and architecture (x64/arm64)
3. It downloads the corresponding binary from GitHub releases (e.g., sus-linux-x86_64.tar.gz)
4. The binary is extracted and made executable
5. The sus command becomes available globally

Installation Options:

npm install -g @superagent/sus
yarn global add @superagent/sus
pnpm add -g @superagent/sus

All changes have been committed and pushed to the cursor/npm-module-packaging-6b70 branch. The package is ready to be published to npm once GitHub releases with the binaries are available.
