Node Versions

Using node on multiple projects is great, until each project starts using a different version of node (╯°□°）╯︵ ┻━┻ Nvm is a tool that allows developers to manage different versions of node on the same machine. Nvm works great in Windows, Linux, and OSX; let’s see if we can get it running on the Windows Subsystem for Linux (WSL). And while we’re at it, let’s get it running with fish and oh-my-fish (my preferred shell).

Nvm is a script not a executable. This means an nvm.sh file is placed on your computer. To “execute” it, the path to the script is included in the .bashrc, .profile, or .zshrc.

Installing nvm

Step 1 Install nvm.sh

From the github page we can start by installing the script curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.34.0/install.sh | bash

Step 2, Install fenv

Next I am going to use the fenv to run nvm.sh from bash with all of the appropriate environment variables set. To install fenv run omf install foreign-env.

Step 3, Setup fish function

The fish shell will allow you to setup aliases just like bash, but it also allows developers to create functions as modules under the .config/fish/functions/ directory. Create a new file in this directory named nvm.fish. Copy and paste the following function into the file

function nvm
    fenv source ~/.nvm/nvm.sh \; nvm $argv
end

Run nvm

Now just restart your shell and start using nvm as you normally would!
