# semver-regex [![Build Status](https://travis-ci.com/sindresorhus/semver-regex.svg?branch=master)](https://travis-ci.com/github/sindresorhus/semver-regex)

> Regular expression for matching [semver](https://github.com/npm/node-semver) versions

## Install

```
$ npm install semver-regex
```

## Usage

```js
const 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']
```

**Note:** For versions coming from user-input, it's up to you to truncate the string to a sensible length to prevent abuse. For example, 100 length.
