A Blade directive to export variables to JavaScript

This package contains a Blade directive to export values to JavaScript.

Here's an example of how it can be used:

@javascript('key', 'value')

The rendered view will output:

<script>window['key'] = 'value';</script>

So in your browser you now have access to a key variable:

console.log(key); //outputs "value"

Installation

You can install the package via composer:

composer require spatie/laravel-blade-javascript

The package will automatically register itself.

Optionally the config file can be published with

php artisan vendor:publish --provider="Spatie\BladeJavaScript\BladeJavaScriptServiceProvider" --tag="config"

This is the contents of the published config file:

return [

    /**
     * All passed values will be present in this JavaScript namespace. Set this to an empty string
     * to use the window object.
     */
    'namespace' => '',
];

If you want to customize the generated <script> tag you can publish and override the used view.

php artisan vendor:publish --provider="Spatie\BladeJavaScript\BladeJavaScriptServiceProvider" --tag="views"

After this you can edit the published view resources/views/vendor/bladeJavaScript/index.blade.php. This is usefull to add the type or a CSP nonce.

Usage

With the package installed you can make use of a @javascript Blade directive.

@javascript('key', 'value')

The rendered view will output:

<script>key = 'value';</script>

You can also use a single argument:

@javascript(['key' => 'value'])

This will also output:

<script>key = 'value';</script>

When setting the namespace to eg js in the config file this will be the output:

<script>window['js'] = window['js'], {};js['key'] = 'value';</script>
