Nave: Node Virtual Environments

Nave (Node Virtual Environments) is a command-line tool designed for managing multiple Node.js versions and their associated global npm package installations. It operates by spawning isolated subshells, allowing users to switch Node.js versions and their global npm environments on a per-session or per-project basis without permanently altering system-wide shell configurations like `.bashrc` or `.profile`. As of version 3.5.6, Nave functions primarily as a Bash script, differentiating it from Node.js-based version managers. Its installation can be achieved by simply downloading the `nave.sh` script or via a global npm installation, which essentially symlinks the script. The project's release cadence is irregular, reflecting maintainer-driven updates rather than a fixed schedule. A key advantage is its lightweight nature and reliance on standard shell features for environment isolation.
