upd-cli 0.0.9

A fast dependency updater for Python and Node.js projects

upd

A fast dependency updater for Python, Node.js, Rust, and Go 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, and Go dependencies
• Fast: Parallel registry requests for all dependencies
• Constraint-aware: Respects version constraints like >=2.0,<3
• 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

Installation

From crates.io

cargo install upd

# or with cargo-binstall (faster, pre-built binary)
cargo binstall upd

From PyPI

pip install upd-cli
# or with uv
uv pip install upd-cli

From source

git clone https://github.com/rvben/upd
cd upd
cargo install --path .

Usage

# Update all dependency files in current directory
upd

# Update specific files or directories
upd requirements.txt pyproject.toml

# Dry-run mode (preview changes without writing)
upd -n
upd --dry-run

# Verbose output
upd -v
upd --verbose

# Disable colored output
upd --no-color

# Disable caching (force fresh lookups)
upd --no-cache

# Filter by update type
upd --major      # Show only major (breaking) updates
upd --minor      # Show only minor updates
upd --patch      # Show only patch updates

# Combine filters
upd --major --minor  # Show major and minor updates only

# Interactive mode - approve updates one by one
upd -i
upd --interactive

# Filter by language/ecosystem
upd --lang python           # Update only Python dependencies
upd -l rust                 # Short form
upd --lang python --lang go # Update Python and Go only

# Version precision
upd --full-precision  # Output full versions (e.g., 3.1.5 instead of 3.1)

# Check mode - exit with code 1 if updates available (for CI/pre-commit)
upd --check
upd -c
upd --check --lang python  # Check only Python dependencies

Commands

# Show version
upd version

# Check for upd updates
upd self-update

# Clear version cache
upd clean-cache

# Align versions across files (use highest version found)
upd align
upd align --check  # Exit 1 if misalignments found (for CI)

Supported Files

Python

• requirements.txt, requirements-dev.txt, requirements-*.txt
• requirements.in, requirements-dev.in, requirements-*.in
• dev-requirements.txt, *-requirements.txt, *_requirements.txt
• pyproject.toml (PEP 621 and Poetry formats)

Node.js

• package.json (dependencies and devDependencies)

Rust

• Cargo.toml ([dependencies], [dev-dependencies], [build-dependencies])

Go

• go.mod (require blocks)

Example Output

pyproject.toml:12: Would update requests 2.28.0 → 2.31.0
pyproject.toml:13: Would update flask 2.2.0 → 3.0.0 (MAJOR)
Cargo.toml:8: Would update serde 1.0.180 → 1.0.200
Cargo.toml:9: Would update tokio 1.28.0 → 1.35.0

Would update 4 package(s) in 2 file(s), 15 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

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

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)
>=2.0	Updates to any version >= 2.0
==2.0.0	No updates (pinned)

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: Inline in requirements.txt (with credentials)
# --index-url https://user:[e-mail]/simple
# or just the URL (credentials from netrc):
# --index-url https://my-private-pypi.com/simple

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
//npm.mycompany.com/:_authToken=your-auth-token
# Or for environment variable reference:
//npm.mycompany.com/:_authToken=${NPM_TOKEN}

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"

Go / Private Module Proxy

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

# Option 2: ~/.netrc file (commonly used with go modules)
# machine proxy.mycompany.com
# login myuser
# password mypassword

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

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