pnpm

upm is a small npm-registry package manager written in TypeScript for Node.js. Its command-line operations are also importable JavaScript functions, allowing it to be embedded in other tools. It reads existing .npmrc configuration and supports package-lock.json, pnpm-lock.yaml, bun.lock, and its own upm.lock format. upm resolves and installs dependencies, manages workspaces, runs package scripts and executables, supports registry and tarball dependencies, and shares content-addressed files between projects through a store. It uses hardlinks when available, skips dependency lifecycle scripts by design, supports frozen, offline, production, verification, deduplication, fetching, and pruning modes, and provides an experimental resolver API that can run in a browser without Node.js. The repository describes it as prerelease software with current limitations including no Git or local-directory dependencies and limited peer-dependency handling. It is distributed under the MIT license and is developed in the unjs organization.

npmx.dev is an open-source web frontend for browsing the npm registry, developed as a fast, modern alternative interface rather than a replacement for the registry. It provides package search and details, README and metadata views, source-code browsing with syntax highlighting and line permalinks, generated API documentation when available, version diffs, changelogs, publish timelines, package comparisons, and shareable URL-driven views. It also surfaces dependency and package-health information such as outdated dependencies, OSV vulnerability warnings, provenance indicators, license and install-script warnings, install size including transitive dependencies, download statistics, repository signals, and JSR availability. The interface supports dark and light modes, localization across dozens of locales including right-to-left languages, keyboard workflows, screen readers, and package, team, and organization administration through the local npm CLI.

npm is the package manager and online registry for JavaScript and Node.js packages. Originally developed by npm, Inc. and now maintained by GitHub, it provides the npm CLI for installing, publishing, and managing packages and the npmjs.com registry for hosting them.

nvm is a POSIX-compliant shell-based version manager for Node.js, designed for per-user installation and per-shell use. It installs, downloads, compiles, switches between, and removes Node.js versions, with support for aliases, LTS release lines, io.js, system Node.js, binary mirrors, offline installation, and migration of global npm packages. A project's .nvmrc file can specify a version that nvm uses when running commands in that project or its subdirectories. nvm is distributed as a sourced Bash script rather than an executable binary and supports POSIX shells including sh, dash, ksh, zsh, and bash on Unix, macOS, and Windows WSL; the repository also documents Docker and shell-completion setups.

snapcn is an MIT-licensed shadcn registry of React and Remotion components for product-demo videos, developed as a Shadcn Labs project. Its catalog includes 21 components for AI chat streams, terminal sessions, device frames, text animation, captions, scenes, logos, social-proof counters, and visual effects. Components are installed with the shadcn CLI, which copies their source and dependencies into a project rather than adding a runtime package. They use theme and mode props through SnapCnTheme to reuse shadcn-style design tokens, and the project also provides a browser editor that composes the components and exports MP4 video. An accompanying agent skill documents the catalog, props, durations, and motion rules so coding agents can select components and assemble timelines.
