Getting Started with Mise

What is mise and how to use it

Mise is a tool for managing tasks, environment variables, and developer tools across projects.

Install and activate mise

To install Mise, run the following command:

curl https://mise.run | sh

Next, add Mise to your shell configuration. For zsh:

echo 'eval "$(~/.local/bin/mise activate zsh)"' >> ~/.zshrc

Using mise

Install a Global Tool

To install Node.js version 22 globally:

mise use --global node@22

Check Tool Version

You can verify the installed version using:

mise exec -- node -v
# Output: v22.x.x

If Mise is activated, you can also run the command directly:

node -v
# Output: v22.x.x

Configuration Files

Mise uses a configuration file to manage tools globally. The global configuration file is located at ~/.config/mise/config.toml. This is an example configuration:

[tools]
node = "22"

Mise also keeps local configuration files in the project directory (mise.toml).

Devtools

To use a specific tool version in a project directory, navigate to the project and run:

cd my-project
mise use node@22

This command ensures the correct version of Node.js (v22) is used within the project.

Environment Variables

You can define project-specific environment variables with Mise. For example:

mise set NODE_ENV=development

This sets the NODE_ENV variable to development for the current project.

Tasks

Mise allows you to define tasks in a mise.toml file. Here’s an example mise.toml file:

[tasks.build]
description = "Build the CLI"
run = "cargo build"

To run the build task, execute:

mise run build

That’s it!

Bonus

Enable just completions by adding this to your mise global file:

[hooks.enter]
shell = "bash"
script = "eval '$(just --completions zsh)'"
