Content is a central entity in the Cellmobs platform, representing all file-based data, such as images, documents, and videos. It plays a crucial role in many aspects of the platform and can be associated with various Cellmobs entities, including Products, DealsTerms, Feeds, Channels, and more.

Developers have the flexibility to use Cellmobs to host their static content or connect their Cellmobs App to their own AWS S3 account or other cloud storage locations such as Dropbox, Box, Google Drive, or OneDrive. This versatility allows developers to choose the storage solution that best fits their requirements and preferences.

Content in Cellmobs is always associated with a primary Organization. This association determines which users have access to read and modify the content, ensuring that content management is securely controlled within the platform.

Content Types

Cellmobs supports different Content Types. They are typically derived from the file mimetype during uploads unless they are explictly provided. It is good practive to pass the ContentType parameter along with a configured FileType.

The main content types are:

Content Type Description
IMAGE All public Images Mime Types
VIDEO All public Video files e.g. mp4, mov, mpeg
AUDIO All public Audio files
DOCUMENT All public documents e.g. doc, pdf, ppt, etc
FOLDER Represents the path to a folder. Either on S3 or another supported storage API
SECURE_FILE Files that are uploaded to private AWS bucket that is only accessible to authorized users where file access is proxied through Cellmobs ACL

FileType is a Content sub type and defines the business use case of a given file. Some file types are system types while others can be freely defined by the application developer.

Images settings for IMAGE file types for example are configured using Image Settings.

Secure Files

When a file contains sensitive information or digital assets that are for sale, you can choose to upload it as a SECURE_FILE to ensure the file is uploaded to a secure storage location.

Access to these files is tightly controlled and regulated. They are not accessible to everyone but only to users who have been explicitly authorized. This ensures that sensitive documents, such as contracts or media records, are only viewed by the intended parties. Similarly, digital assets for sale, like an e-book, movie, or music file, are safeguarded from unauthorized access or downloads (see Product for more).

Authorization can be managed at a granular level, meaning you can control exactly who has access to each individual file. This might be based on user roles, permissions, or even specific transactions (like a user who has just purchased a digital product).


In Cellmobs, when an image file is uploaded, the system by default generates multiple renditions of that image base on configured Image Settings. Rendition profiles for other Content Types will be supported soon

For images renditions are different versions of the original image but in various sizes and dimensions. This automatic generation of image renditions allows your application to serve the most appropriate version of an image based on the context, such as the device screen size or network conditions, improving both performance and user experience.

These renditions could be thumbnails for list views, medium-sized images for detail views, and large or full-sized images for close-up views or zooming. This approach ensures that you always have the right size image for any situation, and you don't have to manually create these versions yourself, saving considerable time and effort.

However, there may be cases where you do not want Cellmobs to generate these renditions. For example, you may want to have full control over how images are resized or manipulated, or you may want to minimize storage usage. In these cases, you can pass the render=false parameter during the image upload process. When this parameter is used, Cellmobs will not generate any renditions of the uploaded image, and only the original image will be stored and available for use in your application.

Remember, the decision to generate renditions or not will depend on your specific needs and the requirements of your application. While the automatic generation of renditions can improve performance and user experience, it may not be necessary or desirable in all cases.
