history

Project history and usage

fnm, short for Fast Node Manager, is a cross-platform Node.js version manager built in Rust. Its official README emphasizes speed, single-file installation, instant startup, and compatibility with `.node-version` and `.nvmrc` project files.

Project history

The project occupies the same problem space as earlier Node version managers but frames its design around a small Rust binary and fast shell startup. Official documentation is split between the repository README and a dedicated `docs` directory covering commands and configuration.

Adoption history

fnm has broad package-manager coverage. The supplied package metadata lists Homebrew, Alpine, Chocolatey, MacPorts, Nix, Arch, Scoop, WinGet, and openSUSE packaging, while the official README documents installation through Homebrew, WinGet, Scoop, Chocolatey, Cargo, release binaries, and an install script.

How it is used

Typical fnm usage starts with installing the binary, evaluating `fnm env` in the user's shell, and letting fnm select Node versions from project files. The README documents shell setup for Bash, Zsh, Fish, PowerShell, and Windows Command Prompt, plus completions for common shells.

Why package nerds care

fnm is significant to package-manager users because it is both a language runtime manager and a packaged CLI with native support across Unix and Windows package ecosystems. Its Rust implementation and project-file compatibility make it a common alternative to shell-heavy Node version managers.

Timeline

  • Current: Official README describes fnm as a fast and simple Node.js version manager built in Rust.
  • Current: Official README documents Homebrew, WinGet, Scoop, Chocolatey, Cargo, release-binary, and install-script installation paths.
  • Current: Supplied package metadata lists fnm across Homebrew, Alpine, Chocolatey, MacPorts, Nix, Arch, Scoop, WinGet, and openSUSE.

Related projects

  • fnm is related to Node.js and project version files such as `.node-version` and `.nvmrc`. It is also related to package-manager distribution channels including Homebrew, WinGet, Scoop, Chocolatey, Cargo, Nix, Arch, Alpine, MacPorts, and openSUSE.
