Cloudinary Integration - FAL Driver

A TYPO3 extension that connect TYPO3 with Cloudinary services by the means of a Cloudinary Driver for FAL. The extension also provides various View Helpers to render images on the Frontend. Cloudinary is a service provider dealing with images and videos. It offers various services among others:

• CDN for fast images and videos delivering
• Manipulation of images and videos such as cropping, resizing and much more...
• DAM functionalities where images can be tagged and metadata edited

Compatibility and Maintenance

This package is currently maintained for the following versions:

Installation

The extension should be done by Composer

Note that the extension will require the library cloudinary/cloudinary_php and be automatically downloaded into vendor.

Configuration

If it is not already the case, create an account on Cloudinary at first. Once the extension is installed, we should create a file storage.

For a new "file storage" record, then:

• Pick the Cloudinary driver in the driver dropdown menu.
• Fill in the requested fields. Password and secrets can be found from the Cloudinary Console.

Once the record is saved, you should see a message telling the connection could be successfully established. You can now head to the File module list. Notice the first time you click on a folder in the File list module, it will take some time since the images must be fetched and put into the cloudinary cache.

Notice you can also use environment variable to configure the storage. The environment variable should be surrounded by %. Example %env(BUCKET_NAME%)

Cloudinary integration as file picker

The extension is providing an integration with Cloudinary so that the editor can directly interact with the cloudinary library in the backend. When clicking on a button, a modal window will open up displaying the Cloudinary files directly. From there, the files can be inserted directly as file references.

To enable this button, we should first configure the extension settings to display the desired button and storage.

We can even take it a step further by enabling auto-login. A new field called authenticationEmail has been added to the storage configuration. By providing a configured email in Cloudinary, we can automatically log in when clicking on the button. Magic!

Configuration TCEFORM

We can configure the form in the backend to hide the default TYPO3 button, thus limiting backend user interaction with the Cloudinary library. Here is an example of such a configuration:

Logging

For the debug purposes Cloudinary API calls are logged to better track and understand how and when the API is called. It might be useful to check the log file in case of a low response time in the BE.

To decide: we now have log level INFO. We might consider "increasing" the level to "DEBUG".

Caveats and troubleshooting

• Free Cloudinary account allows 500 API request per day
• This cloudinary FAL driver is currently limited to images.

ViewHelpers

The extension provides ViewHelpers that can be used like that:

1. Output an images and its source-set.

This will produces the following output:

2. Generate an array of variants that can be iterated.

CLI Command

Move bunch of images from a local storage to a cloudinary storage.

CAUTIOUS!

1. Moving means: we are "manually" uploading a file (skipping FAL API) to the Cloudinary storage and deleting the one from the local storage (rm -f FILE) Finally we are changing the sys_file.storage value to the cloudinary storage. The file uid will be kept!

After "moving" files you should fix the jpeg extension for the Cloudinary storage by running the command below. It is worth mentioning that Cloudinary stripped the file extension for images. For instance a file image.jpg or image.jpeg uploaded on Cloudinary will be stored as image without the file extension. By inspecting the file, we will see that Cloudinary only consider the "jpg" extension. Consequently image.jpeg will be served as image.jpg. This has an implication for us. Record from table sys_file must be adjusted and occurrences jpeg in file identifier or file name must be changed to jpg for consistency.

Tip: to sync / upload a bunch of files, you can use the Cloudinary CLI which is convenient to upload many resources at once.

The extension provides also a tool to copy a bunch of files (restricted to images) from one storage to another. This can be achieved with this command:

For your information a set of acceptance tests has been implemented to validate the functionnalities of the driver.

Development tools

Type command make at the source of the extension to display utility commands related to code formatting.

Web Hook

Whenever uploading or editing a file in the cloudinary library, you can configure in the cloudinary settings a URL to be called as a web hook. This is recommended to keep the data consistent between Cloudinary and TYPO3. When overriding or moving a file across folders, cloudinary will inform TYPO3 that something has changed.

It will basically:

• invalidate the processed files
• invalidate the page cache where the file is involved.

This, however, will not work out of the box and requires some manual configuration. Refer to the file ext:cloudinary/Configuration/TypoScript/setup.typoscript where we define a custom type. This is an example TypoScript file. Make sure that the file is loaded, and that you have defined a storage UID. Your system may contain multiple Cloudinary storages, and each web hook must refer to its own Cloudinary storage. Eventually you will end up having as many config as you have cloudinary storage.
