ud-resolver 1.1.1

A universal dependency resolver supporting multiple package ecosystems

Universal Dependency Resolver

Resolve dependencies across PyPI (pip), npm, Cargo, Go, and more — detect conflicts, check system compatibility, and export to any format.

udr resolve numpy@pypi torch@pypi
  → numpy 1.26.2, torch 2.1.2+cu121 (CUDA 12.1)

Package availability

Source	Install	Published via
PyPI	pip install ud-resolver	GitHub Actions on release
GitHub Releases	pip install ud-resolver-*.whl from Releases	CI on release
GHCR (Docker)	docker pull ghcr.io/code-with-zeeshan/universal-dependency-resolver-backend:latest	CI on every push

The Problem

Your project pulls in packages from everywhere — Python scripts call Node services, Docker images need both pip and apt packages, and your CI pipeline has to pin every transitive dependency across all of them.

Existing tools only work within one ecosystem. pip-compile handles Python. npm ls handles JavaScript. But cross-ecosystem conflicts go undetected until something breaks at runtime. And system compatibility — GPU drivers, CUDA versions, OS patches — is never checked at all.

This tool fixes that.

What It Does

Input:  ["requests>=2.25", "torch==2.0", "express@^4.18"]
                                ↓
               Fetch metadata from PyPI / npm / Conda / ...
               Detect target system (OS, GPU, Python, CUDA)
               Resolve conflicts with SAT solver
                                ↓
Output: Locked dependency tree + export (Dockerfile, requirements.txt, ...)

Quick Example

curl -X POST http://localhost:8000/api/v1/packages/resolve \
  -H "Content-Type: application/json" \
  -d '{
    "packages": [
      {"name": "requests", "ecosystem": "pypi"},
      {"name": "express", "ecosystem": "npm"}
    ],
    "auto_detect_system": true
  }'

Returns a resolved dependency tree with all transitive deps, conflict status, and system compatibility notes.

Feature	What it does
Multi-ecosystem	PyPI (pip), npm, Cargo, Go, Conda, Maven, NuGet, RubyGems, Linux packages, Homebrew
GPU-aware resolution	Scans CUDA, cuDNN, GPU memory — resolves CUDA variants automatically
System scan	Detects OS, CPU, GPU, Python, Node.js, GCC, Java
12 export formats	Dockerfile, requirements.txt, package.json, docker-compose.yml, install.sh, CMakeLists.txt, pyproject.toml, environment.yml, Cargo.toml, build.gradle, pom.xml, Gemfile
CI/CD ready	CLI for pipelines, health check endpoint, structured logging
Desktop app	Cross-platform Electron app with integrated Python backend

Quick Start

PyPI (recommended)

pip install ud-resolver

Install with extras for additional features:

pip install "ud-resolver[system]"       # GPU & system scanning
pip install "ud-resolver[monitoring]"   # OpenTelemetry & Sentry
pip install "ud-resolver[security]"     # Auth & JWT support
pip install "ud-resolver[postgres]"     # PostgreSQL + Redis + Celery
pip install "ud-resolver[all]"          # Everything

From source

git clone https://github.com/code-with-zeeshan/universal-dependency-resolver.git
cd universal-dependency-resolver
pip install -e .

Use as CLI

# Start the API server
udr serve --port 8000

# Check system compatibility
udr check

# Resolve dependencies
udr resolve numpy pandas scikit-learn

# Resolve from other ecosystems
udr resolve react vue -e npm
udr resolve serde tokio -e crates

# Show system info
udr info

# Auto-detect manifests in project dir and lock all deps
udr lock

# Lock with explicit manifest
udr lock --manifest requirements.txt --manifest package.json

# Dry-run lock (no files written)
udr lock --dry-run

# Resolve with JSON output
udr resolve torch torchvision --format json

Desktop app

cd desktop
npm install
npm start

The Electron app spawns the Python backend automatically and opens the Vue.js UI. Binary downloads are available from GitHub Releases.

Web UI

cd frontend && npm install && npm run serve
# → http://localhost:8080

The frontend connects to the backend at http://localhost:8000 (configurable via VUE_APP_API_URL).

Use as Python Library

import asyncio
from backend.core.data_aggregator import DataAggregator
from backend.core.conflict_resolver import ConflictResolver
from backend.core.system_scanner import SystemScanner
from backend.manifest_detector import ManifestDetector

async def main():
    scanner = SystemScanner()
    system_info = await scanner.scan_all()
    print(system_info["platform"]["system"], system_info["cpu"]["brand"])

    aggregator = DataAggregator()
    data = await aggregator.get_package_info("torch", ecosystem="pypi",
                                              include_dependencies=True,
                                              include_versions=True)
    print(data["name"], data["versions"])

    detector = ManifestDetector("./my-project")
    manifests = detector.detect()
    packages = detector.normalize(detector.parse_all(manifests))
    print(f"{len(packages)} packages found")

asyncio.run(main())

Docker (production)

Pre-built images are available on GitHub Container Registry (GHCR):

docker pull ghcr.io/code-with-zeeshan/universal-dependency-resolver-backend:latest
docker pull ghcr.io/code-with-zeeshan/universal-dependency-resolver-frontend:latest

Or build and run locally:

cp .env.example .env
docker compose up -d
docker compose exec backend alembic upgrade head

# Frontend:  http://localhost:8080
# API Docs:  http://localhost:8000/api/v1/docs

Note: The Docker images are published automatically via CI on every push to main and on tags (v*).

How It Works

Your request → Fetch metadata from ecosystem registries
                   ↓
            Scan target system (OS, GPU, Python, CUDA)
                   ↓
            Resolve conflicts with SAT solver
                   ↓
            Export to 12 formats

The system runs as a FastAPI service with optional PostgreSQL, Redis, and a Vue.js frontend.
