Deps <Badge type="warning" text="experimental" />

The mise deps command manages project dependencies by hashing source files (e.g., package-lock.json) and running install commands when changes are detected. It can also add and remove individual packages.

Quick Start

bash

# Enable experimental features
export MISE_EXPERIMENTAL=1

# Install all project dependencies
mise deps

# Add a package
mise deps add npm:react

# Add a dev dependency
mise deps add -D npm:vitest

# Remove a package
mise deps remove npm:lodash

Configuration

Configure deps providers in mise.toml:

toml

# Built-in npm provider (auto-detects lockfile)
[deps.npm]
auto = true  # Auto-run before mise x/run

# Built-in providers for other package managers
[deps.yarn]
[deps.pnpm]
[deps.bun]
[deps.deno]
[deps.aube]
[deps.go]
[deps.pip]
[deps.poetry]
[deps.uv]
[deps.bundler]
[deps.composer]

# Disable specific providers
[deps]
disable = ["npm"]

Built-in Providers

mise includes built-in providers for common package managers:

Provider	Sources	Outputs	Command
`npm`	`package.json`, `package-lock.json`	`node_modules/`	`npm install`
`yarn`	`package.json`, `yarn.lock`	`node_modules/`	`yarn install`
`pnpm`	`package.json`, `pnpm-lock.yaml`	`node_modules/`	`pnpm install`
`bun`	`package.json`, `bun.lock`, `bun.lockb`	`node_modules/`	`bun install`
`deno`	`deno.json`, `deno.jsonc`, `package.json`, `deno.lock`	`node_modules/`	`deno install`
`aube`	`package.json`, `aube-lock.yaml`	`node_modules/`	`aube install`
`go`	`go.mod`	`vendor/` or `go.sum`	`go mod vendor` or `go mod download`
`pip`	`requirements.txt`	`.venv/`	`pip install -r requirements.txt`
`poetry`	`pyproject.toml`, `poetry.lock`	`.venv/`	`poetry install`
`uv`	`pyproject.toml`, `uv.lock`	`.venv/`	`uv sync`
`bundler`	`Gemfile`, `Gemfile.lock`	`vendor/bundle/`	`bundle install`
`composer`	`composer.json`, `composer.lock`	`vendor/`	`composer install`
`dart`	`pubspec.yaml`, `pubspec.lock`	`.dart_tool/`	`dart pub get`
`flutter`	`pubspec.yaml`, `pubspec.lock`	`.dart_tool/`	`flutter pub get`

Built-in providers are only active when explicitly configured in mise.toml and their lockfile exists.

Monorepos

By default, mise deps only runs providers from the current config root. To run providers from every explicitly configured monorepo root, use --monorepo:

toml

monorepo_root = true

[monorepo]
config_roots = ["apps/*", "packages/*"]

bash

mise deps --monorepo

This requires explicit [monorepo].config_roots; mise does not search arbitrary subdirectories for dependency providers. Providers in the monorepo root config are also included because that config is part of every selected config root's hierarchy, matching the behavior of mise install --monorepo.

Monorepo provider IDs include their config root so the same provider can appear in multiple projects. For example, two uv providers are named //apps/api:uv and //apps/worker:uv. Use the qualified name with --only, --skip, or the positional provider argument:

bash

mise deps --monorepo --only //apps/api:uv
mise deps install //apps/worker:uv --monorepo

Provider dependencies without a // prefix are resolved within the same config root. A provider in apps/api with depends = ["uv"] therefore depends on //apps/api:uv.

For a single nested project, the dir option remains a simpler alternative:

toml

[deps.uv]
dir = "apps/api"

Adding and Removing Packages

The mise deps add and mise deps remove commands let you manage individual packages using the ecosystem:package syntax:

bash

# Add packages
mise deps add npm:react
mise deps add npm:@types/react@19
mise deps add -D npm:vitest        # dev dependency

# Remove packages
mise deps remove npm:lodash

The ecosystem prefix tells mise which package manager to use. Currently supported ecosystems for add/remove: npm, yarn, pnpm, bun, deno, aube, dart, flutter.

Custom Providers

Create custom providers for project-specific build steps:

toml

[deps.codegen]
sources = ["schema/*.graphql", "codegen.yml"]
outputs = ["src/generated/"]
run = "npm run codegen"
description = "Generate GraphQL types"

[deps.prisma]
sources = ["prisma/schema.prisma"]
outputs = ["node_modules/.prisma/"]
run = "npx prisma generate"

Provider Options

Option	Type	Description
`auto`	bool	Auto-run before `mise x` and `mise run` (default: false)
`sources`	string[]	Files/patterns to check for changes
`outputs`	string[]	Files/directories that must exist for the provider to be considered fresh
`run`	string	Command to run when stale
`env`	table	Environment variables to set
`dir`	string	Base directory for sources, outputs, and the command
`description`	string	Description shown in output
`depends`	string[]	Other provider names that must complete before this one runs
`timeout`	string	Timeout for the run command, e.g., `"30s"`, `"5m"` (default: no timeout)

Freshness Checking

mise uses blake3 content hashing to determine if sources have changed since the last successful run. Hashes are stored in $MISE_STATE_DIR/deps/<hash>.toml, keyed by project root (so nothing is written inside the project directory).

Compute blake3 hashes of all source files
Compare against stored hashes from the last successful run
If any file was added, removed, or changed, the provider is stale

This means:

If you modify package-lock.json, node_modules/ will be considered stale
If node_modules/ doesn't exist, the provider is always stale
If sources don't exist, the provider is considered fresh (nothing to do)
On first run (no stored state), the provider is always considered stale

Auto-Install

When auto = true is set on a provider, it will automatically run before:

mise run (task execution)
mise x (exec command)

This ensures dependencies are always up-to-date before running tasks or commands.

To skip auto-install for a single invocation:

bash

mise run --no-deps build
mise x --no-deps -- npm test

Staleness Warnings

When using mise activate, mise will warn you if any auto-enabled providers have stale dependencies:

mise WARN deps: npm may need update, run `mise deps`

This can be disabled with:

toml

[settings]
status.show_deps_stale = false

CLI Usage

bash

# Install all project dependencies
mise deps

# Install only a specific provider
mise deps install npm

# Show why a provider is fresh or stale
mise deps install npm --explain

# Show what would run without executing
mise deps install --dry-run

# Force run even if outputs are fresh
mise deps install --force

# List available deps providers
mise deps install --list

# Skip specific providers
mise deps install --skip npm

# Add/remove packages
mise deps add npm:react
mise deps remove npm:lodash

Dependencies

Providers can declare dependencies on other providers using the depends field. A provider will wait for all its dependencies to complete successfully before running.

toml

[deps.uv]
auto = true

[deps.ansible-galaxy]
auto = true
depends = ["uv"]
run = "ansible-galaxy install -r requirements.yml && touch .galaxy-installed"
sources = ["requirements.yml"]
outputs = [".galaxy-installed"]

In this example, ansible-galaxy will wait for uv to finish before starting.

Providers without depends run in parallel as before. If a dependency fails, all providers that depend on it are skipped. Circular dependencies are detected and the affected providers are skipped with a warning.

Parallel Execution

Deps providers run in parallel, respecting the jobs setting for concurrency limits. This speeds up installation when multiple providers need to run (e.g., both npm and pip). Providers with depends will wait for their dependencies to complete before starting, while independent providers run concurrently.

toml

[settings]
jobs = 4  # Run up to 4 providers in parallel

Example: Full-Stack Project

toml

# mise.toml for a project with Node.js frontend and Python backend

[deps.npm]
auto = true

[deps.poetry]
auto = true

[deps.prisma]
auto = true
depends = ["npm"]  # needs node_modules first
sources = ["prisma/schema.prisma"]
outputs = ["node_modules/.prisma/"]
run = "npx prisma generate"

[deps.frontend-codegen]
depends = ["npm"]  # needs node_modules first
sources = ["schema.graphql", "codegen.ts"]
outputs = ["src/generated/"]
run = "npm run codegen"

Running mise deps will install npm and poetry dependencies in parallel, then run prisma and frontend-codegen (also in parallel, since they only depend on npm, not each other).
