API

Prototir.storage

get(key)
The stored string, or null.
set(key, value)
Stores a string for this prototype and the signed-in player.
remove(key)
Removes a value.

Good to know

  • Keys up to 128 characters, values up to 64 KiB of UTF-8. Store JSON as a string for structured data.
  • Prototypes run in an isolated frame with no reliable localStorage, so this goes through the player.

As JSON: /modules/capability-storage.json. Source: Prototir.storage via Player Shell.
