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"

Support us

We invest a lot of resources into creating best in class open source packages. You can support us by buying one of our paid products.

We highly appreciate you sending us a postcard from your hometown, mentioning which of our package(s) you are using. You'll find our address on our contact page. We publish all received postcards on our virtual postcard wall.

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>
