aaronflorey Mise
Mise is a polyglot tool version manager and task runner. It manages dev tools, environment variables, and tasks for projects.
Core Concepts
Configuration: mise.toml in project root (or .mise.toml, .config/mise/config.toml). Config is hierarchical - child directories override parent settings.
Tools: Defined in [tools] section. Mise installs and activates correct versions per-directory.
Environment: Defined in [env] section. Set project-specific env vars that activate when entering directory.
Tasks: Defined in [tasks] section or as standalone scripts in mise-tasks/ directory.
Quick Reference
Basic mise.toml structure:
[tools]
node = "22"
python = "3.12"
[env]
NODE_ENV = "development"
[tasks.build]
run = "npm run build"
Essential Commands
| Command | Description |
|---|---|
mise use node@22 |
Install and set tool version in mise.toml |
mise use -g node@22 |
Set global tool version |
mise install |
Install all tools from config |
mise run <task> |
Run a task |
mise x -- <cmd> |
Execute command with mise environment |
mise ls |
List installed tools |
mise doctor |
Diagnose mise setup |
Tool Backends
Tools can be installed from various backends:
- Core:
node,python,go,ruby(built-in) - npm:
npm:prettier,npm:eslint - pipx:
pipx:black,pipx:ruff - cargo:
cargo:ripgrep - github:
github:BurntSushi/ripgrep - aqua:
aqua:hashicorp/terraform

Common Patterns
Project with Node.js and Python
[tools]
node = "lts"
python = "3.12"
[env]
NODE_ENV = "development"
PYTHONDONTWRITEBYTECODE = "1"
[tasks.dev]
run = "npm run dev"
[tasks.test]
run = ["npm test", "pytest"]
Task with Dependencies
[tasks.build]
run = "npm run build"
sources = ["src/**/*.ts"]
outputs = ["dist/**/*.js"]
[tasks.deploy]
depends = ["build", "test"]
run = "./scripts/deploy.sh"
File Task (mise-tasks/build)
#!/usr/bin/env bash
#MISE description="Build the project"
#MISE depends=["lint"]
npm run build
Environment from .env file
[env]
_.file = ".env"
_.path = "./bin"
Shell Activation
Add to shell rc file to auto-activate mise:
# bash: ~/.bashrc
eval "$(mise activate bash)"
# zsh: ~/.zshrc
eval "$(mise activate zsh)"
# fish: ~/.config/fish/config.fish
mise activate fish | source
Without activation, use mise x -- <command> or mise run <task>.
