Subresource Integrity (SRI) package for Laravel

Latest Version on Packagist Software License Build Status StyleCI

Reference and generate Subresource Integrity (SRI) hashes from your Laravel Elixir asset pipeline.


You can install the package via composer:

composer require sebdesign/laravel-sri

Laravel 5.5 uses Package Auto-Discovery, so doesn't require you to manually add the service provider. If you don't use auto-discovery or you are using an older version, you must add the following:

// config/app.php
'providers' => [


This package is aimed to reference SRI hashes for css and js files from a sri.json file in your /public folder. In order to generate this file, see the laravel-elixir-sri repository.

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.

// Use with elixir() function
    href="{{ elixir('css/app.css') }}"
    integrity="{{ integrity('css/app.css') }}"

// Use with asset() function
    src="{{ asset('js/app.js') }}"
    integrity="{{ integrity('js/app.js') }}" 

If you have set the output folder for the sri.json in a different location in your Gulpfile, you can specify its path on the config/sri.php.

// config/sri.php
'path' => '/public/assets',

You can also override the config options by passing an array as a second argument on the integrity helper function:

// Use different hash algorithm
    href="{{ elixir('css/app.css') }}"
    integrity="{{ integrity('css/app.css', ['algorithms' => ['sha384']]) }}"
