nvm.fish

Node.js version manager lovingly made for Fish.

Not that POSIX-compatible script. Designed from the ground up for Fish, this tool helps you manage multiple active versions of Node on a single local environment. Quickly install and switch between runtimes without cluttering your home directory or breaking system-wide scripts.

  • 100% pure Fish—quick & easy to contribute to or change
  • Tab-completable seamless shell integration
  • .node-version and .nvmrc support
  • XDG Base Directory compliant
  • No setup—it just works!

Installation

Install with Fisher:

fisher install jorgebucaran/nvm.fish

Quickstart

Install the latest Node release and activate it.

nvm install latest

Install the latest LTS (long-term support) Node release.

nvm install lts

Install an older LTS release by codename.

nvm install carbon

Installs 8.16.2, the latest release of the Carbon LTS line.

Or install a specific version of Node.

nvm install v12.9.1

Supports full or partial version numbers, starting with an optional "v".

The nvm install command activates the specified Node version only in the current environment. If you want to set the default version for new shells use:

set --universal nvm_default_version v12.9.1

Activate a version you've already installed.

nvm use v14

List which versions you have installed (includes your system-installed Node if there is one).

$ nvm list
     system
    v8.17.0 lts/carbon
    v12.9.1
 ▶ v14.15.1 lts/fermium
    v15.3.0 latest

Or list all the Node versions available to install.

nvm list-remote

Want to uninstall a Node version?

nvm uninstall v12.9.1

.nvmrc

An .nvmrc file makes it easy to lock a specific version of Node for different projects. Just create an .nvmrc (or .node-version) file containing a version number or alias, e.g., latest, lts, carbon, in the root of your project.

node --version >.nvmrc

Then run nvm install to install or nvm use to activate that version. Works from anywhere inside your project by traversing the directory hierarchy until an .nvmrc is found.

nvm install

$nvm_mirror

If you would like to use a different Node.js mirror that has the same layout as the default at https://nodejs.org/dist, you can set $nvm_mirror. A typical example is users from China using:

set --universal nvm_mirror https://npm.taobao.org/mirrors/node

Acknowledgments

nvm.fish started out in 2016 by @jorgebucaran as Fish's premier choice to Node.js version management. A heartfelt thank you to @creationx and @ljharb for creating the one true nvm.sh that served as the inspiration for this project. If you are looking for a way to use the original nvm right from Fish, check out @FabioAntunes/fish-nvm or @derekstavis/plugin-nvm. Thank you to all our contributors! <3
