SemVer Spec Quick Reference

Caret Ranges (^)

Allows changes that do not modify the left-most non-zero element in [major, minor, patch].

Tilde Ranges (~)

Allows patch-level changes if a minor version is specified, or minor-level changes if only major is given.

Pre-release Precedence

Pre-release tags lower precedence compared to normal clean releases (e.g. 1.0.0-alpha < 1.0.0).

How to use SemVer Comparator & Range Matcher

Using SemVer Comparator & Range Matcher in a development workflow

Use the project’s lockfile and package manager as the source of truth when a displayed version differs from an installed dependency.

Check the project’s versioning rules

  1. Check the project manifest and lockfile together before relying on a version or range result.
  2. Pay attention to these page fields: Target Version:, Range Expression / Constraint:, Comparison Version A:. Confirm which fields are inputs, options, or output areas before processing.
  3. The page exposes these relevant actions: Evaluate. Choose only the action that matches the result you need.
  4. A version comparison does not install or test a package. Review release notes and run the project’s checks before upgrading.

Confirm compatibility in the target project

Version ranges depend on package-manager semantics and project lockfiles. Compare the result with the package manager and registry used by the project.

Frequently Asked Questions (FAQ)

Versions are broken down into major, minor, and patch numeric integers, followed optionally by dot-separated pre-release identifiers and build metadata.

Identifiers like -alpha.1 or -rc signify unstable builds undergoing testing before general production release.
