# semver-regex [![Build Status](https://travis-ci.org/sindresorhus/semver-regex.svg?branch=master)](https://travis-ci.org/sindresorhus/semver-regex) > 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()`.* ## License MIT © [Sindre Sorhus](http://sindresorhus.com)
