As a version manager, Mise handle the different version of your tools for development. It can be used for local development and inside your CICD pipelines.

Installing Tools

Install the latest versions of your favorite tools effortlessly :

mise use python@latest

Managing Your Tools

List installed software :

mise ls
Enter fullscreen mode Exit fullscreen mode

mise-ls

Explore available versions :

mise ls-remote terraform
mise ls-remote terraform@1.11
Enter fullscreen mode Exit fullscreen mode

Mise ls-remote

Search for tools :

mise search jq
Enter fullscreen mode Exit fullscreen mode

Staying Up to Date

Update your tools interactively :

mise up --interactive
Enter fullscreen mode Exit fullscreen mode

mise update

You can also update Mise itself :

mise self-update
Enter fullscreen mode Exit fullscreen mode

Environments

Mise allows you to manage environment variables per project, ensuring your tools and scripts always run in the correct context. This is especially useful for projects requiring specific configurations or secrets.

Set environment variables for a project

Create a .mise.toml file in your project root and define your environment variables :

[env]
DATABASE_HOST ="localhost:5432"
API_KEY ="your_api_key_here"
Enter fullscreen mode Exit fullscreen mode

Mise automatically loads these variables when you enter the project directory, thanks to its shell integration, you just need to trust the file.

mise trust
Enter fullscreen mode Exit fullscreen mode

Handle multiple environments

File .mise.dev.toml :

[env]
DATABASE_HOST ="dev-db:5432"
API_KEY ="dev_key"
Enter fullscreen mode Exit fullscreen mode

File .mise.prd.toml :

[env]
DATABASE_HOST ="prd-db:5432"
API_KEY ="prd_key"
Enter fullscreen mode Exit fullscreen mode

You can switch between environments like this :

MISE_ENV=dev mise env | grep API_KEY
MISE_ENV=prd mise env | grep API_KEY
Enter fullscreen mode Exit fullscreen mode

Tasks

Mise simplifies running repetitive or complex tasks by allowing you to define and execute them directly from your project configuration.

Define tasks

Add a [tasks] section to your .mise.toml file :

[tasks]
start ="docker-compose up"
test ="pytest"
build ="cargo build --release"
deploy ="make deploy"
Enter fullscreen mode Exit fullscreen mode

Run a task

Execute any defined task with :

mise run <task_name>

# Examples:
mise run test
mise run deploy
Enter fullscreen mode Exit fullscreen mode

List available tasks

To see all tasks defined in your project :

mise tasks
Enter fullscreen mode Exit fullscreen mode
