README

This Laravel package enables you to dynamically create Open Graph images for your website based on a single Blade template with HTML and CSS. In our example we use the Tailwind CDN. So designing a dynamic Open Graph Image as a developer just got very easy using this package!

Just add the meta tag with our url to the head of your page. The package will then generate the image and add it to the page. You can edit the view template which you can find in the resources folder.

Requirements

PHP 8.1+

Installation

You can install the package via composer:

composer require vormkracht10/laravel-open-graph-image

Run the command to install the package:

php artisan open-graph-image:install

Then you should install puppeteer:

npm install puppeteer

And make sure Puppeteer can find the correct node and npm versions on your computer or server. When it can't find node or npm, add the custom paths using these .env variables. You can use which node and which npm to find the correct paths to these binaries:

NODE_PATH="" // fill in output of `which node`
NPM_PATH="" // fill in output of `which npm`

You should also publish the views, to change the design of your Open Graph Images:

php artisan vendor:publish --tag="open-graph-image-views"

This is the content of the published config file (published at config/open-graph-image.php):

return [
    'image' => [
        'extension' => 'jpg',
        'quality' => 100,
        'width' => 1200,
        'height' => 630,
    ],

    // The cache location to use.
    'storage' => [
        'disk' => 'public',
        'path' => 'social/open-graph',
    ],

    // Whether to use the browse URL instead of the HTML input.
    // This is slower, but makes fonts available.
    // Alternative: http
    'method' => 'html',

    'metatags' => [
        'og:title' => 'title',
        'og:description' => 'description',
        'og:type' => 'type',
        'og:url' => 'url',
    ],
];

Usage

Just add this blade component into the head of your page.

<x-open-graph-image::metatags title="Vormkracht10" subtitle="Slimme websites" />

If you don't want to use the blade component you can also use the facade or helper method to generate the url to the image.

// Facade
use Vormkracht10\LaravelOpenGraphImage\Facades\OpenGraphImage;

OpenGraphImage::url(['title' => 'Vormkracht10', 'subtitle' => 'Slimme websites']);

// Helper
og(['title' => 'Vormkracht10', 'subtitle' => 'Slimme websites']);

When you share the page on any platform, the image will automatically be generated, cached and then shown in your post. The image from the default template will look like this:

This component uses the 'template' blade view by default. You can change this template to your needs. It is even possible to pass more attributes than the default ones. You can find the default template in the resources folder.

Passing extra attributes

Want to add more custom attributes to modify the button text for example? Simply pass them down to the blade component, facade or helper method:

<x-open-graph-image::metatags
    title="Vormkracht10"
    subtitle="Slimme websites"
    button="Lees meer"
/>

// Facade
use Vormkracht10\LaravelOpenGraphImage\Facades\OpenGraphImage;

OpenGraphImage::url(['title' => 'Vormkracht10', 'subtitle' => 'Slimme websites', 'button' => 'Lees meer']);

// Helper
og(['title' => 'Vormkracht10', 'subtitle' => 'Slimme websites', 'button' => 'Lees meer']);

You can now access the variable in the template.blade.php by using the {{ $button }} variable.

Generate image without using the blade component

When you need to generate the image without using the blade component, you can use the following method:

OpenGraphImage::createImageFromParams(['title' => 'Vormkracht10', 'subtitle' => 'Slimme websites']);

This will return the actual image from your configured storage. You can use this method to generate the image in your own controller for example.

Clearing cached images

All generated open graph images are cached by default. If you want to remove the cache, you can use the following command:

php artisan open-graph-image:clear-cache
