<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>
<p><em>Please, note that this is an alpha version. Check out the <a href="https://github.com/lancedikson/bowser/tree/v1.x">1.x</a> branch for a stable version.</em></p>
<p><strong>Changes of the 2.0</strong>
The upcoming 2.0 version has drastically changed API. All available methods can be found in the <code>docs</code> folder from now on and on a webpage soon.</p>
<h1>Use cases</h1><p>First of all, require the library:</p>
<pre class="prettyprint source lang-javascript"><code>const bowser = require('bowser');</code></pre><p>By default, <code>require('bowser')</code> requires the <em>ES5 version of files</em>, which
<strong>do not</strong> include any polyfills.</p>
<p>In case if 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 make 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 impression = new Impression();

const browser = bowser.getParser(window.navigator.userAgent);
const browserInfo = browser.getBrowser();
impression.brName = browserInfo.name;
impression.brVer = browserInfo.version;</code></pre><p>or</p>
<pre class="prettyprint source lang-javascript"><code>const browser = bowser.getParser(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 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>
<h1>Contributing</h1><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
$ npm test</code></pre><h3>Adding tests</h3><p>See the list in <code>test/acceptance/useragentstrings.yml</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>
