semiver 一个微小的实用程序来比较semver字符串（semivertex）

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.mjsCommonJS: dist/semiver.jsUMD: dist/semiver.min.js

Install

$ npm install --save semiver

Usage

import semiver from 'semiver';// A === Bsemiver('0.0.0', '0.0.0'); //=> 0semiver('1.2.3', '1.2.3'); //=> 0// A > Bsemiver('2.1.0', '1.9.0'); //=> 1semiver('1.9.1', '1.9.0'); //=> 1semiver('10.0.0', '1.0.0'); //=> 1semiver('10.0.0', '8.9.0'); //=> 1semiver('1.2.3-next.10', '1.2.3-next.6'); //=> 1semiver('2.0.0-alpha-10', '2.0.0-alpha-6'); //=> 1semiver('2.0.0-beta.1', '2.0.0-alpha.8'); //=> 1// A < Bsemiver('1.9.0', '2.1.0'); //=> -1semiver('1.9.0', '1.9.1'); //=> -1semiver('1.0.0', '10.0.0'); //=> -1semiver('8.9.0', '10.0.0'); //=> -1semiver('1.2.3-next.6', '1.2.3-next.10'); //=> -1semiver('2.0.0-alpha-6', '2.0.0-alpha-10'); //=> -1semiver('2.0.0-alpha.8', '2.0.0-beta.1'); //=> -1// Sorting[ '4.11.6', '4.2.0', '1.5.19', '1.5.5', '1.0.0', '1.0.0-rc.1', '1.2.3', '1.2.3-alpha', '1.0.0-alpha.1', '1.0.0-alpha', '1.0.0-beta.11', '1.0.0-beta'].sort(semiver);/* [ '1.0.0-alpha', '1.0.0-alpha.1', '1.0.0-beta', '1.0.0-beta.11', '1.0.0-rc.1', '1.0.0', '1.2.3-alpha', '1.2.3', '1.5.5', '1.5.19', '4.2.0', '4.11.6' ]*/
