fnm is a fast and cross-platform Node.js version manager, built in Rust.
Unlike nvm, fnm is designed for speed and efficiency. It downloads pre-built Node.js binaries, minimizing build times and resource consumption.
It is designed to be shell-agnostic, supporting various shells like bash, zsh, fish, and more. fnm allows users to easily install, manage, and switch between multiple Node.js versions on a single system.
This is particularly useful for developers working on multiple projects with different Node.js version requirements.
It supports .node-version files which allows it to automatically switch node versions in a directory if one is found.

fnm relies on pre-built Node.js binaries.
If a specific version is not available as a pre-built binary for your platform, installation may fail.

fnm can be installed using various methods, including curl, and package managers like Homebrew and Scoop.

fnm stores installed Node.js versions in a dedicated directory. This directory is configurable via environment variables. It also supports `.node-version` or `.nvmrc` files for automatic version switching.

fnm was created as an alternative to nvm with a focus on performance and portability.
Being written in Rust gives it the advantages of a fast and cross-platform experience. Its popularity has grown with the increasing need for efficient Node.js version management across diverse development environments.
