## 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)
[![Build Status](https://travis-ci.org/lancedikson/bowser.svg?branch=master)](https://travis-ci.org/lancedikson/bowser/)
So... it works like this:
# Contents
- [Overview](#overview)
- [Use cases](#use-cases)
- [Advanced usage](#advanced-usage)
- [How can I help?](#contributing)
``` js
if (bowser.msie && bowser.version <= 6) {
alert('Hello China');
# 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.
_Please, note that this is an alpha version. Check out the [1.x](https://github.com/lancedikson/bowser/tree/v1.x) branch for a stable version._
**Changes of the 2.0**
The upcoming 2.0 version has drastically changed API. All available methods can be found in the `docs` folder from now on and on a webpage soon.
# Use cases
First of all, require the library:
```
const bowser = require('bowser');
```
## 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 make it with Bowser:
```
const browser = bowser.getParser(window.navigator.userAgent);
console.log(`The current browser name is "${browser.getBrowserName()}"`);
// The current browser name is "Internet Explorer"
```
or
```
const impression = new Impression();
const browser = bowser.getParser(window.navigator.userAgent);
const browserInfo = browser.getBrowser();
impression.brName = browserInfo.name;
impression.brVer = browserInfo.version;
```
or
```
const browser = bowser.getParser(window.navigator.userAgent);
impression.userTechData = browser.parse();
console.log(impression.userTechData);
// 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"
}
}
```
## 1.1.0 breaking changes
We don't save built script in the repo anymore. The main file (`src/bowser.js`) is available through NPM or Bower.
Also you can download minified file from [the release page](https://github.com/ded/bowser/releases).
## 1.0.0 breaking changes
`browser = require('bowser').browser;` becomes `bowser = require('bowser');`
## 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:
## API
```
const browser = bowser.getParsers(window.navigator.userAgent);
const isValidBrowser = browser.satisfies({
// declare browsers per OS
windows: {
"internet explorer": ">10",
},
macos: {
safari: ">10.1"
},
### bowser`:Object`
Use it to get object with detected flags of your current browser.
// per platform (mobile, desktop or tablet)
mobile: {
safari: '>9',
'android browser': '>3.10'
},
### bowser._detect(ua `:String`)`:Object`
Use it to get object with detected flags from User Agent string.
### bowser.check(minVersions`:Object`, strictMode`:Boolean`, [ua]`:String`)`:Boolean`
Use it to check if browser is supported. In default non-strict mode any browser family not present in `minVersions` will pass the check (like Chrome in the third call in the sample bellow). When strict mode is enabled then any not specified browser family in `minVersions` will cause `check` to return `false` (in the sample it is the fourth call, the last one).
``` js
/**
* in case of using IE10
*/
bowser.check({msie: "11"}); // true
bowser.check({msie: "9.0"}); // false
/**
* specific user agent
*/
bowser.check({chrome: "45"}, window.navigator.userAgent); // true
/**
* but false in strict mode
*/
bowser.check({chrome: "45"}, true, window.navigator.userAgent); // false
// or in general
chrome: ">20.1.1432",
firefox: ">31",
opera: ">22"
});
```
### bowser.compareVersions(versions`:Array<String>`)`:Number`
Use it to compare two versions.
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.
``` js
bowser.compareVersions(['9.0', '10']);
// -1
```
More of API and possibilities you will find in the `docs` folder.
### bowser.isUnsupportedBrowser(minVersions`:Object`, [strictMode]`:Boolean`, [ua]`:string`)`:Boolean`
Use it to check if browser is unsupported.
# Advanced Usage
By default, `require('bowser')` requires the pre-compiled file, which can
include useless for you polyfills. In case you don't need that, you can choose
using source file requiring bowser like that: `require('bowser/src/bowser`);
Then you get ES2015 file, which is not precompiled and can be easier to debug.
``` js
bowser.isUnsupportedBrowser({msie: "10"}, window.navigator.userAgent);
// true / false
```
See more examples in [tests](test/test.js).
---
## Bowser Flags
Your mileage may vary, but these flags should be set. See Contributing below.
``` js
alert('Hello ' + bowser.name + ' ' + bowser.version);
```
### All detected browsers
These flags are set for all detected browsers:
* `name` - A human readable name for this browser. E.g. 'Chrome', ''
* `version` - Version number for the browser. E.g. '32.0'
For unknown browsers, Bowser makes a best guess from the UA string. So, these may not be set.
### Rendering engine flags
If detected, one of these flags may be set to true:
* `webkit` - Chrome 0-27, Android <4.4, iOs, BB, etc.
* `blink` - Chrome >=28, Android >=4.4, Opera, etc.
* `gecko` - Firefox, etc.
* `msie` - IE <= 11
* `msedge` - IE > 11
Safari, Chrome and some other minor browsers will report that they have `webkit` engines.
Firefox and Seamonkey will report that they have `gecko` engines.
``` js
if (bowser.webkit) {
// do stuff with safari & chrome & opera & android & blackberry & webos & silk
}
```
### Device flags
If detected, one of these flags may be set to true:
* `mobile` - All detected mobile OSes are additionally flagged `mobile`, **unless it's a tablet**
* `tablet` - If a tablet device is detected, the flag `tablet` is **set instead of `mobile`**.
### Browser flags
If detected, one of these flags may be set to true. The rendering engine flag is shown in []'s:
* `chrome` - [`webkit`|`blink`]
* `chromium` - [`webkit`|`blink`]
* `firefox` - [`gecko`]
* `msie`
* `msedge`
* `safari` - [`webkit`]
* `android` - native browser - [`webkit`|`blink`]
* `ios` - native browser - [`webkit`]
* `opera` - [`blink` if >=15]
* `samsungBrowser` - [`blink`]
* `phantom` - [`webkit`]
* `blackberry` - native browser - [`webkit`]
* `webos` - native browser - [`webkit`]
* `silk` - Amazon Kindle browser - [`webkit`]
* `bada` - [`webkit`]
* `tizen` - [`webkit`]
* `seamonkey` - [`gecko`]
* `sailfish` - [`gecko`]
* `ucbrowser` — [`webkit`]
* `qupzilla` — [`webkit`]
* `vivaldi` — [`blink`]
* `sleipnir` — [`blink`]
* `kMeleon` — [`gecko`]
* `whale` — [`blink`]
For all detected browsers the browser version is set in the `version` field.
### OS Flags
If detected, one of these flags may be set to true:
* `mac`
* `windows` - other than Windows Phone
* `windowsphone`
* `linux` - other than `android`, `chromeos`, `webos`, `tizen`, and `sailfish`
* `chromeos`
* `android`
* `ios` - also sets one of `iphone`/`ipad`/`ipod`
* `blackberry`
* `firefoxos`
* `webos` - may also set `touchpad`
* `bada`
* `tizen`
* `sailfish`
`osname` and `osversion` may also be set:
* `osname` - for the OS flags detected above: macOS, Windows, Windows Phone, Linux, Chrome OS, Android, iOS, Blackberry OS, Firefox OS, WebOS, Bada, Tizen, Sailfish OS, and Xbox
* `osversion` - for Android, iOS, MacOS, Windows, Windows Phone, WebOS, Bada, and Tizen. If included in UA string.
iOS is always reported as `ios` and additionally as `iphone`/`ipad`/`ipod`, whichever one matches best.
If WebOS device is an HP TouchPad the flag `touchpad` is additionally set.
### Browser capability grading
One of these flags may be set:
* `a` - This browser has full capabilities
* `c` - This browser has degraded capabilities. Serve simpler version
* `x` - This browser has minimal capabilities and is probably not well detected.
There is no `b`. For unknown browsers, none of these flags may be set.
### Ender Support
`package.json`
``` json
"dependencies": {
"bowser": "x.x.x"
}
```
``` js
if (require('bowser').chrome) {
alert('Hello Silicon Valley')
}
```
### Contributing
# Contributing
If you'd like to contribute a change to bowser, modify the files in `src/`, then run the following (you'll need node + npm installed):
``` sh
$ npm install
$ make test
$ npm test
```
Please do not check-in the built files `bowser.js` and `bowser.min.js` in pull requests.
### Adding tests
See the list in `src/useragents.js` with example user agents and their expected bowser object.
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.

<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://secure.travis-ci.org/lancedikson/bowser.png" alt="bowser ci"></a></p>
<h1>Contents</h1><ul>
<li>Overview</li>
<li>Use cases</li>
<li>API</li>
<li>How can I help?</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>
<h1>Use cases</h1><p>First of all, require the library:</p>
<pre class="prettyprint source"><code>const Bowser = require('bowser');</code></pre><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 make it with Bowser:</p>
<pre class="prettyprint source"><code>const browser = new Bowser(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"><code>const impression = new Impression();
const browser = new Bowser(window.navigator.userAgent);
const browserInfo = browser.getBrowser();
impression.brName = browserInfo.name;
impression.brVer = browserInfo.version;</code></pre><p>or</p>
<pre class="prettyprint source"><code>const browser = new Bowser(window.navigator.userAgent);
impression.userTechData = browser.parse();
console.log(impression.userTechData);
// 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"><code>const browser = new Bowser(window.navigator.userAgent);
const isValidBrowser = bowser.compare({
// 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;
});</code></pre><p>Settings for any particular OS has more priority and redefines settings of standalone browsers.</p>
<h3>new Bowser(<code>:Object</code>)</h3><p>Use it to get object with detected flags of your current browser.</p>
<h3>bowser._detect(ua <code>:String</code>)<code>:Object</code></h3><p>Use it to get object with detected flags from User Agent string.</p>
<h3>bowser.check(minVersions<code>:Object</code>, strictMode<code>:Boolean</code>, [ua]<code>:String</code>)<code>:Boolean</code></h3><p>Use it to check if browser is supported. In default non-strict mode any browser family not present in <code>minVersions</code> will pass the check (like Chrome in the third call in the sample bellow). When strict mode is enabled then any not specified browser family in <code>minVersions</code> will cause <code>check</code> to return <code>false</code> (in the sample it is the fourth call, the last one).</p>
<pre class="prettyprint source lang-js"><code>/**
* in case of using IE10
*/
bowser.check({msie: &quot;11&quot;}); // true
bowser.check({msie: &quot;9.0&quot;}); // false
/**
* specific user agent
*/
bowser.check({chrome: &quot;45&quot;}, window.navigator.userAgent); // true
/**
* but false in strict mode
*/
bowser.check({chrome: &quot;45&quot;}, true, window.navigator.userAgent); // false</code></pre><h3>bowser.compareVersions(versions<code>:Array&lt;String&gt;</code>)<code>:Number</code></h3><p>Use it to compare two versions.</p>
<pre class="prettyprint source lang-js"><code>bowser.compareVersions(['9.0', '10']);
// -1</code></pre><h3>bowser.isUnsupportedBrowser(minVersions<code>:Object</code>, [strictMode]<code>:Boolean</code>, [ua]<code>:string</code>)<code>:Boolean</code></h3><p>Use it to check if browser is unsupported.</p>
<pre class="prettyprint source lang-js"><code>bowser.isUnsupportedBrowser({msie: &quot;10&quot;}, window.navigator.userAgent);
// true / false</code></pre><p>See more examples in <a href="test/test.js">tests</a>.</p>
<hr>
<h2>Bowser Flags</h2><p>Your mileage may vary, but these flags should be set. See Contributing below.</p>
<pre class="prettyprint source lang-js"><code>alert('Hello ' + bowser.name + ' ' + bowser.version);</code></pre><h3>All detected browsers</h3><p>These flags are set for all detected browsers:</p>
<ul>
<li><code>name</code> - A human readable name for this browser. E.g. 'Chrome', ''</li>
<li><code>version</code> - Version number for the browser. E.g. '32.0'</li>
</ul>
<p>For unknown browsers, Bowser makes a best guess from the UA string. So, these may not be set.</p>
<h3>Rendering engine flags</h3><p>If detected, one of these flags may be set to true:</p>
<p>Safari, Chrome and some other minor browsers will report that they have <code>webkit</code> engines.
Firefox and Seamonkey will report that they have <code>gecko</code> engines.</p>
<pre class="prettyprint source lang-js"><code>if (bowser.webkit) {
// do stuff with safari & chrome & opera & android & blackberry & webos & silk
}</code></pre><h3>Device flags</h3><p>If detected, one of these flags may be set to true:</p>
<ul>
<li><code>mobile</code> - All detected mobile OSes are additionally flagged <code>mobile</code>, <strong>unless it's a tablet</strong></li>
<li><code>tablet</code> - If a tablet device is detected, the flag <code>tablet</code> is <strong>set instead of <code>mobile</code></strong>.</li>
</ul>
<h3>Browser flags</h3><p>If detected, one of these flags may be set to true. The rendering engine flag is shown in []'s:</p>
<ul>
<li><code>chrome</code> - [<code>webkit</code>|<code>blink</code>]</li>
<li><code>firefox</code> - [<code>gecko</code>]</li>
<li><code>msie</code></li>
<li><code>msedge</code></li>
<li><code>safari</code> - [<code>webkit</code>]</li>
<li><code>android</code> - native browser - [<code>webkit</code>|<code>blink</code>]</li>
<li><code>ios</code> - native browser - [<code>webkit</code>]</li>
<li><code>opera</code> - [<code>blink</code> if &gt;=15]</li>
<li><code>samsungBrowser</code> - [<code>blink</code>]</li>
<li><code>phantom</code> - [<code>webkit</code>]</li>
<li><code>blackberry</code> - native browser - [<code>webkit</code>]</li>
<li><code>webos</code> - native browser - [<code>webkit</code>]</li>
<li><code>silk</code> - Amazon Kindle browser - [<code>webkit</code>]</li>
<li><code>bada</code> - [<code>webkit</code>]</li>
<li><code>tizen</code> - [<code>webkit</code>]</li>
<li><code>seamonkey</code> - [<code>gecko</code>]</li>
<li><code>sailfish</code> - [<code>gecko</code>]</li>
<li><code>ucbrowser</code> — [<code>webkit</code>]</li>
<li><code>qupzilla</code> — [<code>webkit</code>]</li>
<li><code>vivaldi</code> — [<code>blink</code>]</li>
<li><code>sleipnir</code> — [<code>blink</code>]</li>
<li><code>kMeleon</code> — [<code>gecko</code>]</li>
</ul>
<p>For all detected browsers the browser version is set in the <code>version</code> field.</p>
<h3>OS Flags</h3><p>If detected, one of these flags may be set to true:</p>
<ul>
<li><code>mac</code></li>
<li><code>windows</code> - other than Windows Phone</li>
<li><code>windowsphone</code></li>
<li><code>linux</code> - other than <code>android</code>, <code>chromeos</code>, <code>webos</code>, <code>tizen</code>, and <code>sailfish</code></li>
<li><code>chromeos</code></li>
<li><code>android</code></li>
<li><code>ios</code> - also sets one of <code>iphone</code>/<code>ipad</code>/<code>ipod</code></li>
<li><code>blackberry</code></li>
<li><code>firefoxos</code></li>
<li><code>webos</code> - may also set <code>touchpad</code></li>
<li><code>bada</code></li>
<li><code>tizen</code></li>
<li><code>sailfish</code></li>
</ul>
<p><code>osversion</code> may also be set:</p>
<ul>
<li><code>osversion</code> - for Android, iOS, MacOS, Windows, Windows Phone, WebOS, Bada, and Tizen. If included in UA string.</li>
</ul>
<p>iOS is always reported as <code>ios</code> and additionally as <code>iphone</code>/<code>ipad</code>/<code>ipod</code>, whichever one matches best.
If WebOS device is an HP TouchPad the flag <code>touchpad</code> is additionally set.</p>
<h3>Browser capability grading</h3><p>One of these flags may be set:</p>
<ul>
<li><code>a</code> - This browser has full capabilities</li>
<li><code>c</code> - This browser has degraded capabilities. Serve simpler version</li>
<li><code>x</code> - This browser has minimal capabilities and is probably not well detected.</li>
</ul>
<p>There is no <code>b</code>. For unknown browsers, none of these flags may be set.</p>
<h3>Ender Support</h3><p><code>package.json</code></p>
<pre class="prettyprint source lang-json"><code>&quot;dependencies&quot;: {
&quot;bowser&quot;: &quot;x.x.x&quot;
}</code></pre><pre class="prettyprint source lang-js"><code>if (require('bowser').chrome) {
alert('Hello Silicon Valley')
}</code></pre><h3>Contributing</h3><p>If you'd like to contribute a change to bowser, modify the files in <code>src/</code>, then run the following (you'll need node + npm installed):</p>
<pre class="prettyprint source lang-sh"><code>$ npm install
$ make test</code></pre><p>Please do not check-in the built files <code>bowser.js</code> and <code>bowser.min.js</code> in pull requests.</p>
<h3>Adding tests</h3><p>See the list in <code>src/useragents.js</code> with example user agents and their expected bowser object.</p>
<p>Whenever you add support for new browsers or notice a bug / mismatch, please update the list and
check if all tests are still passing.</p>

/**
* 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.
