compare two semver version strings, returning -1, 0, or 1
npm install semver-comparecompare two semver version strings, returning -1, 0, or 1
The return value can be fed straight into [].sort.
`` js`
var cmp = require('semver-compare');
var versions = [
'1.2.3',
'4.11.6',
'4.2.0',
'1.5.19',
'1.5.5',
'4.1.3',
'2.3.1',
'10.5.5',
'11.3.0'
];
console.log(versions.sort(cmp).join('\n'));
prints:
`
1.2.3
1.5.5
1.5.19
2.3.1
4.1.3
4.2.0
4.11.6
10.5.5
11.3.0
whereas the default lexicographic sort (versions.sort()) would be:
`
1.2.3
1.5.19
1.5.5
10.5.5
11.3.0
2.3.1
4.1.3
4.11.6
4.2.0
`
var cmp = require('semver-compare')
If the semver string a is greater than b, return 1.b
If the semver string is greater than a, return -1.a
If equals b, return 0;
With npm do:
`
npm install semver-compare
