upd

A fast dependency updater for Python, Node.js, Rust, Go, Ruby, Terraform, GitHub Actions, pre-commit, and Mise projects, written in Rust.

Quick Start

# Run without installing (using uv)
uvx --from upd-cli upd

# Or with pipx
pipx run --spec upd-cli upd

# Preview changes without modifying files
uvx --from upd-cli upd -n

Features

  • Multi-ecosystem: Python, Node.js, Rust, Go, Ruby, Terraform, GitHub Actions, pre-commit, Mise/asdf
  • Fast: Parallel registry requests for all dependencies
  • Constraint-aware: Respects version constraints like >=2.0,<3 and ~> 7.1
  • Smart caching: 24-hour version cache for faster subsequent runs
  • Update filters: Filter by --major, --minor, or --patch updates
  • Interactive mode: Approve updates individually with -i
  • Check mode: Exit with code 1 if updates available (for CI/pre-commit)
  • Major warnings: Highlights breaking changes with (MAJOR)
  • Format-preserving: Keeps formatting, comments, and structure
  • Pre-release aware: Updates pre-releases to newer pre-releases
  • Gitignore-aware: Respects .gitignore when discovering files
  • Version alignment: Align package versions across multiple files
  • Security auditing: Check dependencies for known vulnerabilities via OSV
  • Config file support: Ignore or pin packages via .updrc.toml
  • Private registries: Authentication for PyPI, npm, Cargo, Go, and GitHub

Example Output

.pre-commit-config.yaml:37: Would update pre-commit/pre-commit-hooks v4.6.0 → v6.0.0 (MAJOR)
.github/workflows/ci.yml:16: Would update actions/checkout v4 → v6 (MAJOR)
.github/workflows/ci.yml:18: Would update jdx/mise-action v2 → v4 (MAJOR)
.mise.toml:8: Would update rust 1.91.1 → 1.94.0
Cargo.toml:33: Would update clap 4.5.53 → 4.6.0
Cargo.toml:36: Would update tokio 1.48.0 → 1.50.0

Would update 6 package(s) (2 major, 3 minor, 1 patch) in 4 file(s), 8 up to date

Output includes clickable file:line: locations (recognized by VS Code, iTerm2, and modern terminals).

Version Precision

By default, upd preserves version precision from the original file:

# Original file has 2-component versions
flask>=2.0        →  flask>=3.1        (not 3.1.5)
django>=4         →  django>=6         (not 6.0.0)

# Original file has 3-component versions
requests>=2.0.0   →  requests>=2.32.5

# GitHub Actions major-only tags
actions/checkout@v3  →  actions/checkout@v4  (not @v4.2.0)

Use --full-precision to always output full semver versions:

upd --full-precision
flask>=2.0        →  flask>=3.1.5
django>=4         →  django>=6.0.0
requests>=2.0.0   →  requests>=2.32.5

Version Alignment

In monorepos or projects with multiple dependency files, the same package might have different versions:

# requirements.txt
requests==2.28.0

# requirements-dev.txt
requests==2.31.0

# services/api/requirements.txt
requests==2.25.0

Use upd align to update all occurrences to the highest version found:

upd align              # Align all packages to highest version
upd align --dry-run    # Preview changes
upd align --check      # Exit 1 if misalignments (for CI)
upd align --lang python # Align only Python packages

Behavior:

  • Only aligns packages within the same ecosystem (Python with Python, etc.)
  • Skips packages with upper bound constraints (e.g., >=2.0,<3.0) to avoid breaking them
  • Ignores pre-release versions when finding the highest version

Security Auditing

Check your dependencies for known security vulnerabilities using the OSV (Open Source Vulnerabilities) database:

upd audit              # Scan all dependency files
upd audit --dry-run    # Same as audit (read-only operation)
upd audit --check      # Exit 1 if vulnerabilities found (for CI)
upd audit --lang python # Audit only Python packages
upd audit ./services   # Audit specific directory

Example output:

Checking 42 unique package(s) for vulnerabilities...

Summary: 2 vulnerable package(s), 3 total vulnerability/ies

Supported ecosystems for auditing: PyPI, npm, crates.io, Go, RubyGems

CI/CD Integration:

# GitHub Actions example
- name: Check for vulnerabilities
  run: upd audit --check

Version Constraints

upd respects version constraints in your dependency files:

Constraint Behavior
>=2.0,<3 Updates within 2.x range only
^2.0.0 Updates within 2.x range (npm/Cargo)
~2.0.0 Updates within 2.0.x range (npm)
~> 7.1 Updates within 7.x range (Ruby pessimistic)
>=2.0 Updates to any version >= 2.0
==2.0.0 No updates (pinned)

Configuration File

upd supports configuration files to customize update behavior on a per-project basis.

File Discovery

upd searches for configuration files in the following order (first found wins):

  1. .updrc.toml - Recommended, explicit config file
  2. upd.toml - Alternative name
  3. .updrc - Minimal name (TOML format)

The search starts from the target directory and walks up to parent directories, allowing you to place a config file at the repository root.

Configuration Options

# .updrc.toml

# Packages to ignore during updates (never updated)
ignore = [
    "legacy-package",
    "internal-tool",
    "actions/checkout",        # GitHub Actions use owner/repo
    "pre-commit/pre-commit-hooks",  # Pre-commit hooks too
]

# Pin packages to specific versions (bypasses registry lookup)
[pin]
flask = "2.3.0"
django = "4.2.0"
"actions/setup-node" = "v4"   # Pin GitHub Actions
"psf/black" = "24.0.0"        # Pin pre-commit hooks

Options

Option Type Description
ignore string[] List of package names to skip during updates
pin table Map of package names to pinned versions

Verbose Output

Use --verbose to see which packages are ignored or pinned:

upd --verbose
# Output:
# Using config from: .updrc.toml
#   Ignoring 2 package(s)
#   Pinning 3 package(s)
# pyproject.toml:12: Pinned flask 2.2.0 → 3.0.0 (pinned)
# pyproject.toml:13: Skipped internal-utils 1.0.0 (ignored)

Caching

Version lookups are cached for 24 hours in:

  • macOS: ~/Library/Caches/upd/versions.json
  • Linux: ~/.cache/upd/versions.json
  • Windows: %LOCALAPPDATA%\upd\versions.json

Use upd clean-cache to clear the cache, or upd --no-cache to bypass it.

Private Repositories

upd supports private package registries for all ecosystems. Credentials are automatically detected from environment variables and configuration files.

PyPI / Private Python Index

# Option 1: Environment variables
export UV_INDEX_URL=https://my-private-pypi.com/simple
export UV_INDEX_USERNAME=myuser
export UV_INDEX_PASSWORD=mypassword

# Option 2: PIP-style environment variables
export PIP_INDEX_URL=https://my-private-pypi.com/simple
export PIP_INDEX_USERNAME=myuser
export PIP_INDEX_PASSWORD=mypassword

# Option 3: ~/.netrc file
# machine my-private-pypi.com
# login myuser
# password mypassword

# Option 4: pip.conf / pip.ini
# ~/.config/pip/pip.conf (Linux/macOS)
# %APPDATA%\pip\pip.ini (Windows)
[global]
index-url = https://my-private-pypi.com/simple
extra-index-url = https://pypi.org/simple

# Option 5: Inline in requirements.txt (with credentials)
# --index-url https://user:pass@my-private-pypi.com/simple
# or just the URL (credentials from netrc):
# --index-url https://my-private-pypi.com/simple

pip.conf locations (searched in order):

  1. $PIP_CONFIG_FILE environment variable
  2. $VIRTUAL_ENV/pip.conf (if in a virtual environment)
  3. $XDG_CONFIG_HOME/pip/pip.conf or ~/.config/pip/pip.conf
  4. ~/.pip/pip.conf
  5. /etc/pip.conf (system-wide)

Inline index URLs: When a requirements.txt file contains --index-url or -i, upd automatically uses that index instead of the default PyPI. Credentials can be embedded in the URL (https://user:pass@host/simple) or looked up from ~/.netrc.

npm / Private Registry

# Option 1: Environment variables
export NPM_REGISTRY=https://npm.mycompany.com
export NPM_TOKEN=your-auth-token

# Option 2: NODE_AUTH_TOKEN (GitHub Actions)
export NODE_AUTH_TOKEN=your-auth-token

# Option 3: ~/.npmrc file (global registry)
registry=https://npm.mycompany.com
//npm.mycompany.com/:_authToken=your-auth-token
# Or for environment variable reference:
//npm.mycompany.com/:_authToken=${NPM_TOKEN}

# Option 4: ~/.npmrc file (scoped registries)
@mycompany:registry=https://npm.mycompany.com
//npm.mycompany.com/:_authToken=your-auth-token
@another-scope:registry=https://another.registry.com

Scoped registries: Packages with scopes (e.g., @mycompany/package) will use the registry configured for that scope in .npmrc. This allows mixing public and private packages in the same project.

Cargo / Private Registry

# Option 1: Environment variables
export CARGO_REGISTRY_TOKEN=your-token  # For crates.io default
export CARGO_REGISTRIES_MY_REGISTRY_TOKEN=your-token  # For named registry

# Option 2: ~/.cargo/credentials.toml
[registry]
token = "your-crates-io-token"

[registries.my-private-registry]
token = "your-private-token"

# Option 3: ~/.cargo/config.toml (registry URLs)
[registries.my-private-registry]
index = "https://my-registry.com/git/index"
# or sparse registry:
index = "sparse+https://my-registry.com/index/"

Custom registries: upd reads ~/.cargo/config.toml to discover custom registry URLs. Combine with credentials.toml for authenticated access.

Go / Private Module Proxy

# Option 1: Environment variables
export GOPROXY=https://proxy.mycompany.com
export GOPROXY_USERNAME=myuser
export GOPROXY_PASSWORD=mypassword

# Option 2: Private module patterns
export GOPRIVATE=github.com/mycompany/*,gitlab.mycompany.com/*
export GONOPROXY=github.com/mycompany/*
export GONOSUMDB=github.com/mycompany/*

# Option 3: ~/.netrc file (commonly used with go modules)
# machine github.com
# login myuser
# password mytoken

Private modules: Set GOPRIVATE to specify module patterns that should bypass the public proxy. upd respects these patterns and will attempt direct access for matching modules.

GitHub (Actions & Pre-commit)

# Option 1: GITHUB_TOKEN (automatically available in GitHub Actions)
export GITHUB_TOKEN=ghp_your-token-here

# Option 2: GH_TOKEN (used by the gh CLI)
export GH_TOKEN=ghp_your-token-here

Without a token, the GitHub API rate limit is 60 requests/hour. With a token, it's 5,000 requests/hour.

Use --verbose to see when authenticated access is being used:

upd --verbose
# Output: Using authenticated PyPI access
# Output: Using authenticated npm access
# Output: Using authenticated GitHub access

Pre-commit Integration

Add upd to your .pre-commit-config.yaml:

repos:
  - repo: https://github.com/rvben/upd
    rev: v0.0.22  # Use the latest version
    hooks:
      - id: upd-check
        # Optional: only check specific ecosystems
        # args: ['--lang', 'python']

Available hooks:

Hook ID Description
upd-check Fail if any dependencies are outdated
upd-check-major Fail only on major (breaking) updates

Both hooks run on pre-push by default and trigger when dependency files change.

Note: Requires upd to be installed and available in PATH.
