Overview

The SemVer Validator checks if a version number follows the Semantic Versioning 2.0.0 specification, ensuring accurate and consistent versioning in software projects.

When to Use

  • •When preparing to publish a package to npm or other registries to verify the version string.
  • •When documenting release notes or changelogs to confirm version numbers are correctly formatted.
  • •When automating build or deployment processes that require valid semantic versions for compatibility.

How It Works

  • •Enter the version number in the input field, such as '1.0.0' or '2.1.3-alpha.1'.
  • •The tool parses the input and validates it against SemVer 2.0.0 rules, including pre-release and build metadata.
  • •It returns a text result indicating if the version is valid or invalid, with details on any errors.

Use Cases

Validating npm package versions before publishing to ensure they meet registry standards and avoid errors.
Checking version strings in software documentation or API references to maintain consistency and accuracy.
Integrating into CI/CD pipelines to automatically validate version numbers during build or release steps.

Examples

1. Validating an npm Package Version

Software Developer
Background
A developer is about to publish a new version of their npm package and needs to confirm the version string is correct.
Problem
The version '2.1.0-beta.1' must be validated to prevent publishing issues or compatibility problems.
How to Use
Enter '2.1.0-beta.1' into the version input field and submit for validation.
Outcome
The tool confirms the version is valid, allowing the developer to proceed with publishing.

2. Checking Version in Release Notes

Background
A team is finalizing release notes for a software update and wants to verify the version number mentioned.
Problem
The version '3.0.0-rc.1+exp.sha.5114f85' is complex and might contain formatting errors that could confuse users.
How to Use
Input the version string into the validator to check its compliance with SemVer 2.0.0.
Outcome
The tool validates the version, ensuring it is correctly formatted for clear documentation.

FAQ

What is Semantic Versioning?

Semantic Versioning (SemVer) is a versioning scheme using MAJOR.MINOR.PATCH numbers to communicate changes in software, with optional pre-release and build metadata.

What version formats are supported?

The tool supports standard SemVer 2.0.0 formats, including versions with pre-release identifiers (e.g., 1.0.0-alpha) and build metadata (e.g., 1.0.0+build.1).

Is the validation case-sensitive?

No, the validation is not case-sensitive for pre-release identifiers, but it adheres to SemVer rules for allowed characters and structure.

What happens if the version is invalid?

The tool returns an error message explaining why the version is invalid, such as incorrect format or missing required parts.

Can I validate multiple versions at once?

No, this tool validates one version number per use. For batch validation, you would need to process versions individually or use a different tool.
