npm Backend

You may install packages directly from npmjs.org even if there isn't an asdf plugin for it.

The code for this is inside of the mise repository at ./src/backend/npm.rs.

Dependencies

This relies on having npm installed. You can install it with or without mise. Here is how to install npm with mise:

mise use -g node

Usage

The following installs the latest version of prettier and sets it as the active version on PATH:

$ mise use -g npm:prettier
$ prettier --version
3.1.0

The version will be set in ~/.config/mise/config.toml with the following format:

[tools]
"npm:prettier" = "latest"

Settings

Set these with mise settings set [VARIABLE] [VALUE] or by setting the environment variable listed.

npm.bun

• Type: Bool
• Env: MISE_NPM_BUN
• Default: false

If true, mise will use bun instead of npm if bun is installed and on PATH. This makes installing CLIs faster by using bun as the package manager.

You can install it with mise:

mise use -g bun
