|
> Regular expression for matching [semver](https://github.com/isaacs/node-semver) versions
|
||
|
|
|
||
|
|
|
||
|
|
## Install
|
||
|
|
|
||
|
|
```sh
|
||
|
|
$ npm install --save semver-regex
|
||
|
|
```
|
||
|
|
|
||
|
|
|
||
|
|
## Usage
|
||
|
|
|
||
|
|
```js
|
||
|
|
var semverRegex = require('semver-regex');
|
||
|
|
|
||
|
|
semverRegex().test('v1.0.0');
|
||
|
|
//=> true
|
||
|
|
|
||
|
|
semverRegex().test('1.2.3-alpha.10.beta.0+build.unicorn.rainbow');
|
||
|
|
//=> true
|
||
|
|
|
||
|
|
semverRegex().exec('unicorn 1.0.0 rainbow')[0];
|
||
|
|
//=> 1.0.0
|
||
|
|
|
||
|
|
'unicorn 1.0.0 and rainbow 2.1.3'.match(semverRegex());
|
||
|
|
//=> ['1.0.0', '2.1.3']
|
||
|
|
```
|
||
|
|
|
||
|
|
*It's a function so you can create multiple instances. Regexes with the global flag will have the `.lastIndex` property changed for each call to methods on the instance. Therefore reusing the instance with multiple calls will not work as expected for `.test()`.*
