 1 | # PHP Babel Transpiler
 2 | 
 3 | [![Build Status](https://travis-ci.org/talyssonoc/php-babel-transpiler.svg)](https://travis-ci.org/talyssonoc/php-babel-transpiler)
 4 | 
 5 | Transform JavaScript with [Babel](https://babeljs.io/) from PHP.
 6 | 
 7 | ## Installation
 8 | 
 9 | ### V8Js dependency
10 | 
11 | It's important to know that `php-babel-transpiler` has a dependency of the [v8js](https://pecl.php.net/package/v8js) PHP extension.
12 | 
13 | You can see how to install it here: [how to install V8Js](https://github.com/talyssonoc/react-laravel/blob/master/install_v8js.md).
14 | 
15 | ### Composer
16 | 
17 | ```sh
18 |   php composer.phar require talyssonoc/php-babel-transpiler
19 | ```
20 | 
21 | ## Usage
22 | 
23 | ```php
24 |   $transpiledCode = Babel\Transpiler::transform('class MyClass {  }');
25 |   $otherTranspiledCode = Babel\Transpiler::transformFile('/my/Class.js', [ 'blacklist' => [ 'useStrict' ] ]);
26 | ```
27 | 
28 | ## API
29 | 
30 | - `Babel\Transpiler::transform($sourceCode, $babelOptions)`: Transpile the given source code, passing the given options to Babel, and return the transformed code.
31 | - `Babel\Transpiler::transformFile($filePath, $babelOptions)`: Transpile the file with the given **absolute** path, passing the given options to Babel, and return the transformed code.
