xpm stands for xPack project manager and is a Node.js CLI application to manage xPack projects; it can install both source and binary xPacks.

xpm is an extension to npm and shares the same public packages repository (npmjs.com).

The open source project is hosted on GitHub as xpack/xpm-js.

xPacks overview

xPacks are general purpose multi-version software packages, built on top of the highly successful npm packages in the Node.js JavaScript ecosystem.

Please read the xPacks Overview and xPack 101 pages.


The main purpose of the xpm CLI tool is to install xPacks, including all dependent xPacks, and to easily update them when new versions are released.

For developers, the xPack tools provide a very convenient way of publishing the software packages, using the same central repository as npm.
