Flux
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 in package.json. Downloaded package tarballs are stored in a shared per-user cache for reuse in later projects. Flux can be installed globally as an npm package or used as a standalone binary that does not require Node.js. The npm installation requires Node 18 or later; the standalone binary includes no runtime. Flux reads and writes package.json and installs into node_modules. It is MIT licensed and free for personal and commercial use, with no paid tier, telemetry, or account requirement, according to the maker. The alpha installs direct dependencies only and lacks dependency tree resolution and lockfile support, so installs are not reproducible. The maker says it is not ready for production and recommends it for side projects and experiments, advising users to keep npm or pnpm for projects they ship. Flux runs on Linux, macOS, and Windows.
