Spec score 7.7 #9 of 19 in JavaScript Package Managers

What it is

Flux is an open-source command-line package manager for JavaScript and Node.js projects, built by Gautam Suthar. It installs, updates, lists, and removes packages from the npm registry, and runs scripts defined in package.json. Packages are placed in node_modules, while downloaded tarballs remain in a shared per-user cache that later projects can reuse. Flux is available through a global npm installation or as a standalone binary without Node.js. The npm route requires Node 18 or later; the standalone binary includes no runtime. It runs on Linux, macOS, and Windows, uses package.json, and has no workspace or lockfile support. The alpha handles direct dependencies only, without dependency-tree resolution, so installs are not reproducible. Flux has no telemetry, requires no account, and is MIT licensed for personal and commercial use. The maker recommends it for side projects and experiments, not production projects.
