About:
A robust JavaScript library for parsing and comparing semantic version strings, following the SemVer 2.0.0 specification. It is the core versioning engine used by npm and provides utilities for validating version ranges, checking constraints, and sorting versions.
Key Features:
  • Parses and compares semantic version strings
  • Handles version ranges and constraints (e.g., ^1.2.3, ~4.5.6)
  • Validates version numbers against the SemVer spec
  • Sorts an array of versions
  • Powering npm's own dependency resolution
Use Cases:
  • Validating and comparing dependency versions in Node.js projects
  • Implementing custom version range logic in development tools
  • Filtering and sorting software releases by version
Alternatives:
  • semver for Rust – Rust implementation; not a direct alternative for Node.js/JavaScript environments
  • python-semver – Python library for semantic versioning; different language ecosystem
