# semver-compare
compare two semver version strings, returning -1, 0, or 1
The return value can be fed straight into `[].sort`.
[](http://travis-ci.org/substack/semver-compare)
# example
``` 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
```
# methods
```
var cmp = require('semver-compare')
```
## cmp(a, b)
If the semver string `a` is greater than `b`, return `1`.
If the semver string `b` is greater than `a`, return `-1`.
If `a` equals `b`, return 0;
# install
With [npm](https://npmjs.org) do:
```
npm install semver-compare
