2025 Report: Destructive Malware in Open Source Packages
Destructive malware is rising across open source registries, using delays and kill switches to wipe code, break builds, and disrupt CI/CD.
@microsoft/rush-lib
Advanced tools
This is a companion package for the Rush tool. See the @microsoft/rush package for details.
The rush-lib package implements the rush.json config file loader and some other helpful utilities. Tools that want to reuse this functionality can install rush-lib alone to avoid inadvertently adding another "rush" executable to the command-line path (which might interfere with the globally installed Rush).
The @microsoft/rush version number is always exactly equal to the @microsoft/rush-lib version number that it depends on.

Rush is part of the Rush Stack family of projects.
Lerna is a popular tool for managing JavaScript projects with multiple packages. It optimizes the workflow around managing multi-package repositories with git and npm. Compared to @microsoft/rush-lib, Lerna is more focused on JavaScript and TypeScript projects and offers a simpler setup, but it may not scale as well for very large monorepos.
Nx is a set of extensible dev tools for monorepos, which helps you develop like Google, Facebook, and Microsoft. It offers powerful integrations with modern frameworks and libraries. Compared to @microsoft/rush-lib, Nx provides more advanced features for code generation, testing, and CI/CD pipelines, making it a more comprehensive solution for modern web development.
