Platform Support

macOS / Linux

Uses lsof and ps commands for port detection and process management.

Windows

Uses netstat, tasklist, taskkill, and wmic for port detection and process management.

Requirements

• Runtime: Node.js >= 18.0.0
• Development: Node.js >= 18.0.0
• Binary Build: Node.js 18.x (pkg currently supports up to Node.js 18)

For standalone binaries, no runtime is required - they are self-contained executables with Node.js 18 embedded.

Note: The pkg tool currently supports up to Node.js 18. When Node.js 22 support is added to pkg, update the build scripts to use node22-* targets.

Build Process: Binaries are created by bundling the code with esbuild (to handle ES modules) and then packaging with pkg.

Development

Run in development mode

npm run dev

Type checking

npm run check-types

Build TypeScript

npm run build:ts
