Installing Fast Node Manager (fnm)

Using a node manager helps you deal with annoying npm permissions issues.

If you already use something like nvm you'll notice fnm is significantly faster.

Install

On Mac:

brew install fnm

On Linux:

sudo apt install curl

The following command will automatically install fnm using curl

curl -fsSL https://fnm.vercel.app/install | bash -s -- --install-dir $HOME/.local/bin

If you don't already have .local/bin in your path

export PATH=/home/$USER/.local/bin/fnm:$PATH

Upgrade

curl -fsSL https://fnm.vercel.app/install | bash -s -- --install-dir $HOME/.local/bin --skip-shell

bashrc/zshrc config

Add the following to you .bashrc or .zshrc

eval "$(fnm env)"

Commands

List install candidates

fnm ls-remote

Install a node version

fnm install 13.14.0

List currently installed versions

fnm ls

Choose version you would like to use

fnm use 13.14.0

Check currently active version

fnm current

Alias a version

fnm alias 13.14.0 nickname fnm use nickname

Default a version

fnm default 13.14.0

Autocompletions

You can replace zsh with bash if you are using bash

mkdir -p ~/.config/zsh/completions touch ~/.config/zsh/completions/_fnm fnm completions --shell=zsh > ~/.config/zsh/completions/_fnm

Then add the following to your .zshrc:

fpath+=~/.config/zsh/completions/_fnm compinit

Wrapping up

Versioning node should be much faster now
