semver-extra contains useful methods that aren't included in the vanilla semver package.
The main reason semver-extra exists is to deal with pre-release versions.
``bash`
$ npm install semver-extra --save
`js`
var semver = require('semver-extra');
First of all, semver-extra contains all methods of semver@4.x, so we could use semver-extra only without the vanilla one.
`js`
semver.validRange('^1.2.3'); // '>=1.2.3-0 <2.0.0-0'
`js`
semver.isStable('1.2.3'); // -> true
semver.isStable('1.2.3-stable'); // -> false
semver.isStable('1.2.3-alpha'); // -> false
Checks whether the version is a stable version.
- version string
- prerelease prerelease
- If argument is not passed and version is an unstable version, it will return true.prerelease
- or could be the pre-release string.
`js`
semver.isPrerelease('1.2.3'); // false
semver.isPrerelease('1.2.3-beta'); // true
semver.isPrerelease('1.2.3-beta', 'alpha'); // false
semver.isPrerelease('1.2.3-1.2.3', '1.2.3'); // true, that supports numeric prerelease versions
semver.isPrerelease('1.2.3-alpha.1', 'alpha.1'); // true
Checks whether the version is an unstable version or matches the prerelease.
`js`
var versions = [
'1.1.2'
'1.2.3-beta',
'1.2.2',
'1.2.1',
'1.3.3',
'1.5.0-rc'
];
`js`
semver.max(versions); // '1.5.0-rc'
Returns String the maximun version in the list.
`js`
semver.maxStable(versions); // '1.3.3'
Returns String the maximun stable version in the list.
`js``
semver.maxPrerelease(versions, 'alpha'); // null
semver.maxPrerelease(versions); // '1.5.0-rc'
semver.maxPrerelease(versions, 'beta'); // '1.2.3-beta'
Returns the maximun (matched) pre-release version matches the prerelease.
