# Contributing
We're always open to pull requests or code reviews. Everyone can become a permanent contributor. Just ping @lancedikson in the issues or on Twitter ❤️
## Branches
The project runs Git-flow, where the `master` branch is for development and `production` is for production.
In a nutshell, if you are proposing a new feature that adds totally new functionality to `bowser`, it's better to branch from `master` and make a PR pointing back to `master` as well.
If it's a small hot-fix, an improvement to the docs, or added support for a new browser/OS/platform/etc, then it's better to branch from `production` and make a PR pointing back to `production`.
Following these simple rules will really help maintain the repo! Thanks ❤️
## Adding Tests
See the list in `test/acceptance/useragentstrings.yml` with example user agents and their expected `bowser` object.
Whenever you add support for new browsers or notice a bug / mismatch, please update the list and
check if all tests are still passing.
## Testing
If you'd like to contribute a change to `bowser`, modify the files in `src/`, and run the following (you'll need `node` + `npm` installed):
``` sh
$ npm install
$ npm run build #build
$ npm test #run tests
$ npm run lint #check lint rules
```

## Bowser
A browser detector. Because sometimes, there is no other way, and not even good modern browsers always provide good feature detection mechanisms.
[![Build Status](https://travis-ci.org/lancedikson/bowser.svg?branch=master)](https://travis-ci.org/lancedikson/bowser/) [![Greenkeeper badge](https://badges.greenkeeper.io/lancedikson/bowser.svg)](https://greenkeeper.io/)[![Coverage Status](https://coveralls.io/repos/github/lancedikson/bowser/badge.svg?branch=master)](https://coveralls.io/github/lancedikson/bowser?branch=master)

# Overview
The library is made to help to detect what browser your user has and gives you a convenient API to filter the users somehow depending on their browsers.
### ⚠️ Version 2.0 breaking changes ⚠️
Version 2.0 has drastically changed the API. All available methods are on the [docs page](https://lancedikson.github.io/bowser/docs).
_For legacy code, check out the [1.x](https://github.com/lancedikson/bowser/tree/v1.x) branch and install it through `npm install bowser@1.9.4`._
# Use cases
First of all, require the library. This is a UMD Module, so it will work for AMD, TypeScript, ES6, and CommonJS module systems.
```javascript
const Bowser = require("bowser"); // CommonJS
import * as Bowser from "bowser"; // TypeScript
import Bowser from "bowser"; // ES6 (and TypeScript with --esModuleInterop enabled)
```
By default, the exported version is the *ES5 transpiled version*, which **do not** include any polyfills.
In case you don't use your own `babel-polyfill` you may need to have pre-built bundle with all needed polyfills.
So, for you it's suitable to require bowser like this: `require('bowser/bundled')`.
As the result, you get a ES5 version of bowser with `babel-polyfill` bundled together.
You may need to use the source files, so they will be available in the package as well.
## Browser props detection
Often we need to pick users' browser properties such as the name, the version, the rendering engine and so on. Here is an example how to do it with Bowser:
```javascript
const browser = Bowser.getParser(window.navigator.userAgent);
console.log(`The current browser name is "${browser.getBrowserName()}"`);
// The current browser name is "Internet Explorer"
```
or
```javascript
const browser = Bowser.getParser(window.navigator.userAgent);
console.log(browser.getBrowser());
// outputs
{
name: "Internet Explorer"
version: "11.0"
}
```
or
```javascript
console.log(Bowser.parse(window.navigator.userAgent));
// outputs
{
browser: {
name: "Internet Explorer"
version: "11.0"
},
os: {
name: "Windows"
version: "NT 6.3"
versionName: "8.1"
},
platform: {
type: "desktop"
},
engine: {
name: "Trident"
version: "7.0"
}
}
```
## Filtering browsers
You could want to filter some particular browsers to provide any special support for them or make any workarounds.
It could look like this:
```javascript
const browser = Bowser.getParser(window.navigator.userAgent);
const isValidBrowser = browser.satisfies({
// declare browsers per OS
windows: {
"internet explorer": ">10",
},
macos: {
safari: ">10.1"
},
// per platform (mobile, desktop or tablet)
mobile: {
safari: '>=9',
'android browser': '>3.10'
},
// or in general
chrome: "~20.1.1432",
firefox: ">31",
opera: ">=22"
// also supports equality operator
chrome: "=20.1.1432", // will match particular build only
// and loose-equality operator
chrome: "~20" // will match any 20.* sub-version
chrome: "~20.1" // will match any 20.1.* sub-version (20.1.19 as well as 20.1.12.42-alpha.1)
});
```
Settings for any particular OS or platform has more priority and redefines settings of standalone browsers.
Thus, you can define OS or platform specific rules and they will have more priority in the end.
More of API and possibilities you will find in the `docs` folder.

<article><h2>Bowser</h2><p>A browser detector. Because sometimes, there is no other way, and not even good modern browsers always provide good feature detection mechanisms.</p>
<p><a href="https://travis-ci.org/lancedikson/bowser/"><img src="https://travis-ci.org/lancedikson/bowser.svg?branch=master" alt="Build Status"></a> <a href="https://greenkeeper.io/"><img src="https://badges.greenkeeper.io/lancedikson/bowser.svg" alt="Greenkeeper badge"></a><a href="https://coveralls.io/github/lancedikson/bowser?branch=master"><img src="https://coveralls.io/repos/github/lancedikson/bowser/badge.svg?branch=master" alt="Coverage Status"></a></p>
<h1>Contents</h1><ul>
<li><a href="#overview">Overview</a></li>
<li><a href="#use-cases">Use cases</a></li>
<li><a href="#advanced-usage">Advanced usage</a></li>
<li><a href="#contributing">How can I help?</a></li>
</ul>
<h1>Overview</h1><p>The library is made to help to detect what browser your user has and gives you a convenient API to filter the users somehow depending on their browsers.</p>
<h3>⚠️ Version 2.0 breaking changes ⚠️</h3><p>Version 2.0 has drastically changed the API. All available methods are on the <a href="https://lancedikson.github.io/bowser/docs">docs page</a>.</p>
<p><em>For legacy code, check out the <a href="https://github.com/lancedikson/bowser/tree/v1.x">1.x</a> branch and install it through <code>npm install bowser@1.9.4</code>.</em></p>
<h1>Use cases</h1><p>First of all, require the library. This is a UMD Module, so it will work for AMD, TypeScript, ES6, and CommonJS module systems.</p>
<pre class="prettyprint source lang-javascript"><code>const Bowser = require(&quot;bowser&quot;); // CommonJS
import * as Bowser from &quot;bowser&quot;; // TypeScript
import Bowser from &quot;bowser&quot;; // ES6 (and TypeScript with --esModuleInterop enabled)</code></pre><p>By default, the exported version is the <em>ES5 transpiled version</em>, which <strong>do not</strong> include any polyfills.</p>
<p>In case you don't use your own <code>babel-polyfill</code> you may need to have pre-built bundle with all needed polyfills.
So, for you it's suitable to require bowser like this: <code>require('bowser/bundled')</code>.
As the result, you get a ES5 version of bowser with <code>babel-polyfill</code> bundled together.</p>
<p>You may need to use the source files, so they will be available in the package as well.</p>
<h2>Browser props detection</h2><p>Often we need to pick users' browser properties such as the name, the version, the rendering engine and so on. Here is an example how to do it with Bowser:</p>
<pre class="prettyprint source lang-javascript"><code>const browser = Bowser.getParser(window.navigator.userAgent);
console.log(`The current browser name is &quot;${browser.getBrowserName()}&quot;`);
// The current browser name is &quot;Internet Explorer&quot;</code></pre><p>or</p>
<pre class="prettyprint source lang-javascript"><code>const browser = Bowser.getParser(window.navigator.userAgent);
console.log(browser.getBrowser());
// outputs
{
name: &quot;Internet Explorer&quot;
version: &quot;11.0&quot;
}</code></pre><p>or</p>
<pre class="prettyprint source lang-javascript"><code>console.log(Bowser.parse(window.navigator.userAgent));
// outputs
{
browser: {
name: &quot;Internet Explorer&quot;
version: &quot;11.0&quot;
},
os: {
name: &quot;Windows&quot;
version: &quot;NT 6.3&quot;
versionName: &quot;8.1&quot;
},
platform: {
type: &quot;desktop&quot;
},
engine: {
name: &quot;Trident&quot;
version: &quot;7.0&quot;
}
}</code></pre><h2>Filtering browsers</h2><p>You could want to filter some particular browsers to provide any special support for them or make any workarounds.
It could look like this:</p>
<pre class="prettyprint source lang-javascript"><code>const browser = Bowser.getParser(window.navigator.userAgent);
const isValidBrowser = browser.satisfies({
// declare browsers per OS
windows: {
&quot;internet explorer&quot;: &quot;>10&quot;,
},
macos: {
safari: &quot;>10.1&quot;
},
// per platform (mobile, desktop or tablet)
mobile: {
safari: '>=9',
'android browser': '>3.10'
},
// or in general
chrome: &quot;~20.1.1432&quot;,
firefox: &quot;>31&quot;,
opera: &quot;>=22&quot;
// also supports equality operator
chrome: &quot;=20.1.1432&quot;, // will match particular build only
// and loose-equality operator
chrome: &quot;~20&quot; // will match any 20.* sub-version
chrome: &quot;~20.1&quot; // will match any 20.1.* sub-version (20.1.19 as well as 20.1.12.42-alpha.1)
});</code></pre><p>Settings for any particular OS or platform has more priority and redefines settings of standalone browsers.
Thus, you can define OS or platform specific rules and they will have more priority in the end.</p>
<p>More of API and possibilities you will find in the <code>docs</code> folder.</p>

Work and such Derivative Works in Source or Object form.
3. Grant of Patent License. Subject to the terms and conditions of
this License, each Contributor hereby grants to You a perpetual,
worldwide, non-exclusive, no-charge, royalty-free, irrevocable
(except as stated in this section) patent license to make, have made,
use, offer to sell, sell, import, and otherwise transfer the Work,
where such license applies only to those patent claims licensable
by such Contributor that are necessarily infringed by their
Contribution(s) alone or by combination of their Contribution(s)
with the Work to which such Contribution(s) was submitted. If You
institute patent litigation against any entity (including a
cross-claim or counterclaim in a lawsuit) alleging that the Work
or a Contribution incorporated within the Work constitutes direct
or contributory patent infringement, then any patent licenses
granted to You under this License for that Work shall terminate
as of the date such litigation is filed.
4. Redistribution. You may reproduce and distribute copies of the
Work or Derivative Works thereof in any medium, with or without
modifications, and in Source or Object form, provided that You
meet the following conditions:
(a) You must give any other recipients of the Work or
Derivative Works a copy of this License; and
(b) You must cause any modified files to carry prominent notices
stating that You changed the files; and

of the following places: within a NOTICE text file distributed
as part of the Derivative Works; within the Source form or
documentation, if provided along with the Derivative Works; or,
within a display generated by the Derivative Works, if and
wherever such third-party notices normally appear. The contents
of the NOTICE file are for informational purposes only and
do not modify the License. You may add Your own attribution
notices within Derivative Works that You distribute, alongside
or as an addendum to the NOTICE text from the Work, provided
that such additional attribution notices cannot be construed
as modifying the License.
You may add Your own copyright statement to Your modifications and
may provide additional or different license terms and conditions
for use, reproduction, or distribution of Your modifications, or
for any such Derivative Works as a whole, provided Your use,
reproduction, and distribution of the Work otherwise complies with
the conditions stated in this License.
5. Submission of Contributions. Unless You explicitly state otherwise,
any Contribution intentionally submitted for inclusion in the Work
by You to the Licensor shall be under the terms and conditions of
this License, without any additional terms or conditions.
Notwithstanding the above, nothing herein shall supersede or modify
the terms of any separate license agreement you may have executed
with Licensor regarding such Contributions.
6. Trademarks. This License does not grant permission to use the trade

7. Disclaimer of Warranty. Unless required by applicable law or
agreed to in writing, Licensor provides the Work (and each
Contributor provides its Contributions) on an "AS IS" BASIS,
WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
implied, including, without limitation, any warranties or conditions
of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
PARTICULAR PURPOSE. You are solely responsible for determining the

8. Limitation of Liability. In no event and under no legal theory,
whether in tort (including negligence), contract, or otherwise,
unless required by applicable law (such as deliberate and grossly
negligent acts) or agreed to in writing, shall any Contributor be
liable to You for damages, including any direct, indirect, special,
incidental, or consequential damages of any character arising as a
result of this License or out of the use or inability to use the
Work (including but not limited to damages for loss of goodwill,
work stoppage, computer failure or malfunction, or any and all
other commercial damages or losses), even if such Contributor
has been advised of the possibility of such damages.
9. Accepting Warranty or Additional Liability. While redistributing
the Work or Derivative Works thereof, You may choose to offer,
and charge a fee for, acceptance of support, warranty, indemnity,
or other liability obligations and/or rights consistent with this
License. However, in accepting such obligations, You may act only
on Your own behalf and on Your sole responsibility, not on behalf
of any other Contributor, and only if You agree to indemnify,
defend, and hold each Contributor harmless for any liability
incurred by, or claims asserted against, such Contributor by reason
of your accepting any such warranty or additional liability.

/**
* Browsers' descriptors
*
* The idea of descriptors is simple. You should know about them two simple things:
* 1. Every descriptor has a method or property called `test` and a `describe` method.
* 2. Order of descriptors is important.
*
* More details:
* 1. Method or property `test` serves as a way to detect whether the UA string
* matches some certain browser or not. The `describe` method helps to make a result
* object with params that show some browser-specific things: name, version, etc.
* 2. Order of descriptors is important because a Parser goes through them one by one
* in course. For example, if you insert Chrome's descriptor as the first one,
* more then a half of browsers will be described as Chrome, because they will pass
* the Chrome descriptor's test.
*
* Descriptor's `test` could be a property with an array of RegExps, where every RegExp
* will be applied to a UA string to test it whether it matches or not.
* If a descriptor has two or more regexps in the `test` array it tests them one by one
* with a logical sum operation. Parser stops if it has found any RegExp that matches the UA.
*
* Or `test` could be a method. In that case it gets a Parser instance and should
* return true/false to get the Parser know if this browser descriptor matches the UA or not.
