ud-resolver 1.2.1

A universal dependency resolver supporting multiple package ecosystems

Universal Dependency Resolver

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

udr resolve numpy pandas scikit-learn
udr resolve react vue -e npm

Install

pip install ud-resolver

With extras:

Install flag	Adds
[system]	GPU & system scanning (psutil, pynvml, cpuinfo)
[postgres]	PostgreSQL support (psycopg2-binary, asyncpg)
[monitoring]	OpenTelemetry & Sentry instrumentation
[all]	Everything

Quick Start

# Resolve dependencies
udr resolve numpy pandas scikit-learn
udr resolve react vue -e npm

# Lock a project's dependencies
udr lock
udr lock --manifest requirements.txt --manifest package.json

# Check system compatibility
udr check
udr info

# Start API server
udr serve --port 8000

Python Library

import asyncio
from backend.core.data_aggregator import DataAggregator
from backend.core.conflict_resolver import ConflictResolver

async def main():
    aggregator = DataAggregator()
    info = await aggregator.get_package_info("flask", ecosystem="pypi")
    print(info["versions"])

    resolver = ConflictResolver()
    result = resolver.resolve([{"name": "flask", "version": ">=2.0"}])

asyncio.run(main())
