semiver 
A tiny (187B) utility to compare semver strings.
Compare semver strings (eg, 1.8.2, 2.0.0-next.6, 0.0.0-alpha-1, etc) using the Intl.Collator class.
Version suffixes are supported and are considered during comparison.
The output will always be 0, 1, or -1, allowing semiver to be used directly as a compare function for Array.sort().
This module exposes three module definitions:
- ES Module:
dist/semiver.mjs - CommonJS:
dist/semiver.js - UMD:
dist/semiver.min.js
Install
$ npm install --save semiver
Usage
import semiver from 'semiver';
// A === B
semiver('0.0.0', '0.0.0'); //=> 0
semiver('1.2.3', '1.2.3'); //=> 0
// A > B
semiver('2.1.0', '1.9.0'); //=> 1
semiver('1.9.1', '1.9.0'); //=> 1
semiver('10.0.0', '1.0.0'); //=> 1
semiver('10.0.0', '8.9.0'); //=> 1
semiver('1.2.3-next.10', '1.2.3-next.6'); //=> 1
semiver('2.0.0-alpha-10', '2.0.0-alpha-6'); //=> 1
semiver('2.0.0-beta.1', '2.0.0-alpha.8'); //=> 1
// A < B
semiver('1.9.0', '2.1.0'); //=> -1
semiver('1.9.0', '1.9.1'); //=> -1
semiver('1.0.0', '10.0.0'); //=> -1
semiver('8.9.0', '10.0.0'); //=> -1
semiver('1.2.3-next.6', '1.2.3-next.10'); //=> -1
semiver('2.0.0-alpha-6', '2.0.0-alpha-10'); //=> -1
