ToDesktop FS

Securely interact with the file system.

Installation

Install @todesktop/client-fs in your client-side application using

npm install @todesktop/client-fs

Installation of the plugin package is also necessary. Using ToDesktop Builder, navigate to Plugins. Click on the Explore button for "File System" and install the package.

Security

For security considerations, usage of this plugin is restricted in the following ways:

• Paths accessed by this library must begin with one of our whitelisted directories:

  • all: All directories (NOTE: This gives access to entire file system so only use it if absolutely necessary for your use case).
  • home: The current user's home directory.
  • userData: Directory for storing your app's configuration files.
  • appData: Per-user application data directory.
  • desktop: The current user's Desktop directory.
  • documents: Directory for a user's 'My Documents'.
  • downloads: Directory for a user's downloads.
  • music: Directory for a user's music.
  • pictures: Directory for a user's pictures.
  • videos: Reads the entire contents of a file.
  • recent: Directory for the user's recent files.
  • temp: Temporary directory.

• FS functionality is enabled on a function-by-function basis via the ToDesktop Builder interface. This means that you can expose the readFile functionality to your client app, but prohibit writeFile.
