mise

Overview

mise manages tool versions — Node.js, Python, Go, Rust, Ruby, etc. One tool replaces nvm, pyenv, rbenv, and asdf. Also runs project tasks.

Instructions

Step 1: Install

curl https://mise.run | sh
echo 'eval "$(mise activate bash)"' >> ~/.bashrc

Step 2: Configuration

# mise.toml — Project tool versions and tasks
[tools]
node = "20"
python = "3.12"
go = "1.22"

[env]
DATABASE_URL = "postgresql://localhost/myapp"

[tasks.dev]
run = "npm run dev"

[tasks.test]
run = "npm test"

mise install    # install all tools
mise run dev    # run task

Guidelines

• mise is 10-100x faster than asdf (Rust vs bash).
• Reads .tool-versions, .node-version, .python-version — drop-in replacement.
• Tasks in mise.toml replace Makefiles and package.json scripts.
