File Storage

The file storage module allows you to manage files in your app on a scalable file storage technology (e.g., Amazon S3) without having to write any backend code.


  • Create a folder
  • Upload/download a file
  • List all files/folders within a folder
  • Delete a file/folder

Use caseslink

  • Making a file management app (eg: Google Drive)
  • File sharing in any social media app (eg: Facebook, Instagram)
  • Pictures for product catalogues in e-commerce apps (e.g., Amazon)

Supported file storage technologieslink

You can select one of the following storage technologies for your project in Space Cloud:

  • Amazon S3
  • Google Cloud Storage
  • Local file system

Configuring file storage modulelink

Open your project in Mission Control and head to the File Storage section.

Enable the file storage module.

Select an appropriate file storage technology for your project. The default is Local File Storage.

Then copy-paste the connection string of the selected file storage and hit Save.

This connection string is used by Space Cloud to connect to the selected file storage. In the case of Local File Storage, connection string is the path of the folder where you want to store all your files.

Note: Before you can use the file storage module from the frontend, you should secure the file storage module with security rules too.

How it workslink

The file storage module provides REST APIs for file management.

Whenever the client requests any file operation (e.g., upload), Space Cloud validates whether the request is authorized by applying the security rules provided in the Mission Control.

If the request is authorized, Space Cloud makes a corresponding request to the selected file storage technology and returns the result to the client. Else it returns a 401 or 403 error to the client.
