Download the PHP package rkcreative/aws-image-handler without Composer

AWS Serverless Image Handler Laravel Package

This package provides a Laravel wrapper for the AWS Serverless Image Handler service.

Requirements

• PHP >= 7.3
• Laravel >= 5.0
• An AWS account with Image Handler service installed

Installation

You can install the package via composer:

After installing the package, the AwsImageHandlerServiceProvider and the ImageHandler facade are automatically registered, thanks to Laravel's package discovery feature.

If you're using Laravel 5.5 or later, no further steps are required. You can start using the ImageHandler facade right away:

If you're using a version of Laravel that's earlier than 5.5, you'll need to manually register the service provider and facade. Add the following lines to the providers and aliases arrays in your config/app.php file:

Configuration

After installing the package, you should publish the configuration file:

This command will create a aws-image-handler.php configuration file in your config directory. In this file, you can set your distribution URL and the default S3 bucket:

You should also add the AWS_IMAGE_HANDLER_URL and AWS_IMAGE_HANDLER_S3_BUCKET variables to your .env file:

Usage

Here's a detailed example of how to use the ImageHandler class:

In this example, the resize macro is used to set the desired image dimensions, and then the createUrl method is used to generate the URL for the transformed image. The resulting URL will look something like this:

In this URL, your-cloudfront-url.com is your CloudFront distribution URL, and the long base64 string is the encoded edit options.

Using the Alias

The package also provides an alias, which you can use for even easier access. Here's an example:

In this example, ImageHandler::resize(200, 200) is equivalent to (new Rkcreative\AwsImageHandler\Services\ImageHandler())->resize(200, 200). You can use this alias anywhere in your Laravel application.

Available Macros

The ImageHandler class comes with the following macros:

• smartCrop
• roundCrop
• contentModeration
• crop
• quality
• resize
• setRgba
• rotate

You can use these macros like any other method on the ImageHandler class:

Extending with Custom Macros

You can extend the ImageHandler class with your own macros. The options are from the Sharp Node.js image processing library. Here's how to do it:

1. Create a new service provider:

2. In the boot method of your new service provider, add your macro:

In this example, the blur macro receives a blur value as an argument. The blur value is then added to the image handler options. The macro modifies the state of the ImageHandler instance and then returns the instance itself, allowing for method chaining.

3. Register your new service provider in the providers array in config/app.php:

Now, you can use your macro like any other method on the ImageHandler class:

In this example, the blur macro is used to add a blur effect to the image. The blur value can be any number between 0.3 (low blur) and 1000 (maximum blur).
