T6030 public-reads-visitor
A screen whose cache states public reads user, or a state kept in the device. A warning.
Details
A screen kept as public may be kept by a cache outside the engine, which hands every visitor the copy that was drawn for nobody. Such a screen reads neither the user nor a state kept in the device in its own view, nor calls useUser. A component it uses may read either where it states personal: true: it is a personal part, which the copy does not hold and the page draws once it has come alive (option.component.personal).
TSX
cache: { for: 60_000, public: true },
view: ({ user }) => <p>{user ? user.id : ''}</p>, // T6030The fix
Take public away from cache, read neither the user nor a state kept in the device, or move what reads them into a component that states personal: true.
