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.

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.x or 1.0.*.
• 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.
• npm version ranges, e.g. 1.2.7 || >=1.2.9 <2.0.0

Install

$ npm install compare-versions

Note: 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.

Usage

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'); // -1

Can 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'
]
*/

"Human Readable" Compare

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', '>='); // false

Version ranges

The 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'); // false

Validate version numbers

Applies 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');        // false

Validate version numbers (strict)

Validate 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');      // false

Browser

In modern browsers the functions above can be imported as modules:

<script type="module">
  import { compareVersions, compare, satisfies, validate, validateStrict } from './node_modules/compare-versions/lib/esm/index.js'
  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'))
</script>

Legacy (UMD)

If 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, validateStrict } = 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'))
</script>
