npm license Travis AppVeyor Coverage Status

libcipm installs npm projects in a way that's optimized for continuous integration/deployment/etc scenarios. It gives up the ability to build its own trees or install packages individually, as well as other user-oriented features, in exchange for speed, and being more strict about project state.

For documentation about the associated command-line tool, see cipm.


$ npm install libcipm

Table of Contents


  • npm-compatible project installation
  • lifecycle script support

  • npm-compatible caching
  • errors if package.json and package-lock.json are out of sync, instead of fixing it like npm does. Essentially provides a --frozen install.
