Mise | Sebastien Day

I mentioned swapping nvm for mise when I moved over to Arch last summer. Nine months in and it’s become one of my favourite tools.

Mise is one tool that replaces nvm, pyenv, rbenv, asdf, direnv and a small pile of install scripts. It handles Node, Python, Ruby, Bun, Go, Rust, the Shopify CLI, etc for me.

Install

On Arch it’s in the repos:

sudo pacman -S mise

Then activated in my bash config:

if command -v mise &> /dev/null; then
  eval "$(mise activate bash)"
fi

It hooks into the prompt and swaps the right versions in when I cd into a project.

Global config

My global setup lives in ~/.config/mise/config.toml:

[tools]
python = "latest"
node = "22"
"npm:@shopify/cli" = "latest"

Three things I use everywhere - Python, Node LTS and the Shopify CLI. The npm: prefix is cool - mise will install a global npm package and pin it, so I can upgrade the Shopify CLI just like any other tool with mise up.

Per-project

Every project gets a .mise.toml at the root.

# shopify-import
[tools]
ruby = "3.3"

Running mise ls on my machine right now:

Tool              Version  Source                      Requested
bun               1.3.12
node              22.22.2  ~/.config/mise/config.toml  latest
npm:@shopify/cli  3.93.2   ~/.config/mise/config.toml  latest
npm:wrangler      4.84.1   ~/.config/mise/config.toml  latest
python            3.10.19
python            3.13.7   ~/.config/mise/config.toml  latest
ruby              3.3.10   ~/.config/mise/config.toml  latest

Why I like it

Replaces nvm and does other languages as well

.mise.toml in the repo means anyone cloning gets the right versions with mise install
Global npm packages get versioned too

I’m still using nvm on my olders debian servers for now, mostly because they’re set up and I haven’t wanted to touch them. But next time I rebuild a server it’ll be mise there too.
