Data Hooks

Hooks for reading and writing general-purpose state variables (data.* namespace).

Every data variable must be declared in data in your appfunnel.config.ts before it can be used. Undeclared keys will be ignored.

`useData<T>(key)`

Read/write a data.* variable. Auto-prefixes with data..


const [tier, setTier] = useData<string>('selectedPlanTier')
const [seen, setSeen] = useData<boolean>('hasSeenOnboarding')

Return	Type	Description
`[0]`	`T`	Current value
`[1]`	`(value: T) => void`	Setter function
