compare-versions

compare-versions

Compare semver version strings to find greater, equal or lesser. Runs in the browser as well as Node.js/React Native etc. Has no dependencies and is tiny (~630 bytes gzipped).

This library supports the full semver specification, including comparing versions with different number of digits like 1.0.0, 1.0, 1, and pre-release versions like 1.0.0-alpha. Additionally supports the following variations:

• Supports wildcards for minor and patch version like 1.0.x or 1.0.*.
• Supports Chromium version numbers with 4 parts, e.g. version 25.0.1364.126.
• Any leading v is ignored, e.g. v1.0 is interpreted as 1.0.
• Leading zero is ignored, e.g. 1.01.1 is interpreted as 1.1.1.

Install

$ npm install compare-versions

Usage

Import

// ES6/TypeScript
import compareVersions from 'compare-versions';

// Node
var compareVersions = require('compare-versions');

Compare

compareVersions('10.1.8', '10.0.4'); //  1
compareVersions('10.0.1', '10.0.1'); //  0
compareVersions('10.1.1', '10.2.2'); // -1

Can also be used for sorting:

var versions = [
  '1.5.19',
  '1.2.3',
  '1.5.5'
]
var sorted = versions.sort(compareVersions);
/*
[
  '1.2.3',
  '1.5.5',
  '1.5.19'
]
*/
var sortDescending = versions.sort(compareVersions).reverse();
/*
[
  '1.5.19'
  '1.5.5',
  '1.2.3',
]
*/

"Human Readable" Compare

The normal compare function doesn't return a self-explanatory value (using 1, 0 and -1). This version returns the boolean which fulfills the specified operator.

compareVersions.compare('10.1.8', '10.0.4', '>'); // return true
compareVersions.compare('10.0.1', '10.0.1', '='); // return true
compareVersions.compare('10.1.1', '10.2.2', '<'); // return true
compareVersions.compare('10.1.1', '10.2.2', '<='); // return true
compareVersions.compare('10.1.1', '10.2.2', '>='); // return false

Validate version numbers

Applies the same ruleset as used before comparing version numbers and returns a boolean:

compareVersions.validate('1.0.0-rc.1'); // return true
compareVersions.validate('1.0-rc.1'); // return false
compareVersions.validate('foo'); // return false

Browser

If included directly in the browser, compareVersions() is available on the global window:

<script src="compare-versions/index.js"></script>
<script>
  window.compareVersions('10.0.0', '10.1.0');
</script>
