MaxNPM - A More Rational npm Client

MaxNPM is a npm client that utilizes PacSolve, a dependency solver using Rosette (a Z3-based SAT solver), to find the optimal dependency graph for a given set of dependencies. It offers several benefits over traditional npm, including minimizing the size of the node_modules folder by reducing the number of dependencies, improving the management of project vulnerabilities more effectively than npm audit fix, reducing the number of duplicate dependencies (that is multiple versions of the same dependency), and allowing users to choose the latest compatible version of a dependency with better results than a normal npm install.

The MaxNPM paper can be found here.

Installation

MaxNPM can be installed by simply running npm install -g maxnpm. The binaries included in the package in the npm registry are built for Linux version >= 4.10. For earlier versions of Linux or other operating systems, you will need to build MaxNPM from source.

Usage

MaxNPM can be used as a drop-in replacement for npm by specifying the --maxnpm flag when running maxnpm install, as it uses the same interface as npm (except for the maxnpm binary prefix). Constraints are specified using the flag --minimize <constraint1>,<constraint2>,..., where the precedence of the constraints is the order in which they are specified.

Out of the box, we currently support the following constraints:

  • min_oldness: minimizes the number of installed old versions
  • min_num_deps: minimizes the number of dependencies
  • min_duplicates: minimizes the number of duplicate dependencies
  • min_cve: minimizes the number of vulnerabilities

For example, if you want to minimize the number of old versions and the number of vulnerabilities, you would run maxnpm install --maxnpm --minimize min_oldness,min_cve.
