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.
Supports the full semver specification including versions with different number of digits like 1.0.0, 1.0, 1 and pre-releases like 1.0.0-alpha. Additionally supports the following variations:
- Wildcards for minor and patch version like
1.0.xor1.0.*. - Chromium version numbers with 4 parts, e.g. version
25.0.1364.126. - Any leading
vis ignored, e.g.v1.0is interpreted as1.0. - Leading zero is ignored, e.g.
1.01.1is interpreted as1.1.1. - npm version ranges, e.g.
1.2.7 || >=1.2.9 <2.0.0
$ npm install compare-versionsNote: Starting from v5 the main export is now named like so: import { compareVersions } from 'compare-versions'.
Note: Starting from v4 this library includes a ESM version which will automatically be selected by your bundler (webpack, parcel etc). The CJS/UMD version is lib/umd/index.js and the new ESM version is lib/esm/index.js.
Will return 1 if first version is greater, 0 if versions are equal, and -1 if the second version is greater:
import { compareVersions } from 'compare-versions';
compareVersions('11.1.1', '10.0.0'); // 1
compareVersions('10.0.0', '10.0.0'); // 0
compareVersions('10.0.0', '11.1.1'); // -1Can also be used for sorting:
const versions = [
'1.5.19',
'1.2.3',
'1.5.5'
]
const sorted = versions.sort(compareVersions);
/*
[
'1.2.3',
'1.5.5',
'1.5.19'
]
*/The alternative compare function accepts an operator which will be more familiar to humans:
import { compare } from 'compare-versions';
compare('10.1.8', '10.0.4', '>'); // true
compare('10.0.1', '10.0.1', '='); // true
compare('10.1.1', '10.2.2', '<'); // true
compare('10.1.1', '10.2.2', '<='); // true
compare('10.1.1', '10.2.2', '>='); // falseThe satisfies function accepts a range to compare, compatible with npm package versioning:
import { satisfies } from 'compare-versions';
satisfies('10.0.1', '~10.0.0'); // true
satisfies('10.1.0', '~10.0.0'); // false
satisfies('10.1.2', '^10.0.0'); // true
satisfies('11.0.0', '^10.0.0'); // false
satisfies('10.1.8', '>10.0.4'); // true
satisfies('10.0.1', '=10.0.1'); // true
satisfies('10.1.1', '<10.2.2'); // true
satisfies('10.1.1', '<=10.2.2'); // true
satisfies('10.1.1', '>=10.2.2'); // false
satisfies('1.4.6', '1.2.7 || >=1.2.9 <2.0.0'); // true
satisfies('1.2.8', '1.2.7 || >=1.2.9 <2.0.0'); // false
satisfies('1.5.1', '1.2.3 - 2.3.4'); // true
satisfies('2.3.5', '1.2.3 - 2.3.4'); // falseApplies the same rules used comparing version numbers and returns a boolean:
import { validate } from 'compare-versions';
validate('1.0.0-rc.1'); // true
validate('1.0-rc.1'); // false
validate('foo'); // falseValidate version numbers strictly according to semver.org; 3 integers, no wildcards, no leading zero or "v" etc:
import { validateStrict } from 'compare-versions';
validate('1.0.0'); // true
validate('1.0.0-rc.1'); // true
validate('1.0'); // false
validate('1.x'); // false
validate('v1.02'); // falseIf included directly in the browser, the functions above are available on the global window under the compareVersions object:
<script src=https://unpkg.com/compare-versions/lib/umd/index.js></script>
<script>
const { compareVersions, compare, satisfies, validate } = window.compareVersions
console.log(compareVersions('11.0.0', '10.0.0'))
console.log(compare('11.0.0', '10.0.0', '>'))
console.log(satisfies('1.2.0', '^1.0.0'))
console.log(validate('11.0.0'))
console.log(validateStrict('11.0.0'))
