+# laravel-elixir-sri
+
+[![npm version](http://img.shields.io/npm/v/laravel-elixir-sri.svg)](https://npmjs.org/package/laravel-elixir-sri) [![npm license](http://img.shields.io/npm/l/laravel-elixir-sri.svg)](https://npmjs.org/package/laravel-elixir-sri)
+
+Generate [Subresource Integrity (SRI)](https://www.w3.org/TR/SRI/) hashes in your Laravel Elixir asset pipeline.
+
+## Install
+
+```
+npm install laravel-elixir-sri --save-dev
+```
+
+or
+
+```
+yarn add laravel-elixir-sri --dev
+```
+
+## Usage within Laravel Elixir
+
+### Example Gulpfile:
+
+```javascript
+var elixir = require('laravel-elixir');
+
+require('laravel-elixir-sri');
+
+elixir(function (mix) {
+    mix.sri([
+        'css/app.css',
+        'js/app.js'
+    ]);
+});
+```
+
+This will generate hashes for the given files stored in your **public folder** and save them to a `/public/sri.json` file.
+
+### Changing the output folder:
+
+You can specify a different output folder in the second argument:
+
+```javascript
+// Save sri.json to /public/assets
+mix.sri('css/app.css', '/public/assets');
+```
+
+### Parameters:
+
+If you wish to customize more options, you can pass them as an object in the third argument:
+
+```javascript
+// Use sha512 algorithm
+mix.sri('js/app.js', null, {
+    algorithms: ['sha512']
+});
+```
+You can find all the available parameters on `gulp-sri`'s [documentation](https://www.npmjs.com/package/gulp-sri#parameters).
+
+## Usage within Laravel views
+
+First, you need to require the [laravel-sri]('https://github.com/sebdesign/laravel-sri') package in your `composer.json`.
+
+To reference the generated hashes from the `sri.json` in your views, you may use the `integrity` helper function with the name of the file you are using in your `elixir` or `asset` function.
+
+As a fallback, if the given file is not found in the `sri.json`, **it will generate the appropriate hashes on the fly** for your convenience. Read more on the [laravel-sri]('https://github.com/sebdesign/laravel-sri') repository.
+
+```php
+{{-- Use with elixir() function --}}
+<link rel="stylesheet" href="{{ elixir('css/app.css') }}" integrity="{{ integrity('css/app.css') }}" crossorigin="anonymous">
+
+{{-- Use with asset() function --}}
+<script src="{{ asset('js/app.js') }}" integrity="{{ integrity('js/app.js') }}" crossorigin="anonymous"></script>
+```
