Types of Variables
This documentation is about setting variables on the current tab/frame.
If you need to store data that are accessible to multiple team members, or across page loads, see PixieBrix’s Team Databases feature
Mod Variables are variables that are shared across starter bricks in a mod, and available across runs of the mod during a page session. Reloading a page or navigating to a different page clears the Mod Variables for the tab.
Example situations of when to use Mod Variables are:
Keep track of whether a mod has already run on a page
Making information available on a Sidebar
Pass information between frames or tabs (Advanced)
Advanced: Page State is in-memory storage that persists during a page session. There are 3 Page State namespaces to isolate information:
Private — accessible only for bricks attached to the starter brick
Mod — accessible to all bricks in the mod
Public — accessible to all bricks
PixieBrix stores Mod Variables in the Mod Page State.
