Browserslist Check Bundle
=========================

[](#browserslist-check-bundle)

This bundle parses `.browserslistrc` files for a config called `modern`. It then provides a php service and a twig method to compare the user-agent string against this config.

It uses a great, light and fast [user agent parsing library](https://github.com/donatj/PhpUserAgent)by [@donatj](https://github.com/donatj).

The goal is to determine whether the browser requesting a response is "modern" in relation to JavaScript and CSS functionality.

You can use it to serve different front-end builds and save precious bandwidth for modern browsers by serving less polyfills, vendor prefixes and whatever else is handled by the `.broserslistrc`.

Installing
----------

[](#installing)

```
composer require barthy-koeln/browserslist-check-bundle
```

Config
------

[](#config)

Your `.browserslistrc` file should look like this:

```
[modern]
Chrome >= 97
Edge >= 97
Firefox >= 91
Safari >= 14.1
Opera >= 82
iOS >= 14.5
Samsung >= 15
ChromeAndroid >= 100
FirefoxAndroid >= 98
Android >= 99

[legacy]
defaults
ie 11
safari >= 13
iOS >= 13

```

Important notes:

- The `[modern]` config must be at the top
- The constraints within that build must only map browser names with minimum versions using the `>=` operator. Browsers with versions higher or equal are "modern".

Caching The Browser Configuration
---------------------------------

[](#caching-the-browser-configuration)

Your `.browserslistrc` file will be parsed and inlined as a PHP array when Symfony builds its cache.

Crawlers & Bots
-------------------

[](#crawlers--bots)

This bundle recognizes a few evergreen crawlers capable of handling JavaScript and handles them as their browser counterpart (e.g. Chrome for Googlebot and Edge for Bingbot).

Simple Usage
------------
