Response Hooks

Hooks for reading and writing quiz/survey response variables (answers.* namespace).

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

`useResponse<T>(key)`

Read/write a single response variable. This is the primary hook for capturing visitor answers.


const [goal, setGoal] = useResponse<string>('goal')
const [interests, setInterests] = useResponse<string[]>('interests')

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

Returns all response variables as a flat object with the answers. prefix stripped. Only re-renders when an answers.* variable changes.


const responses = useResponses()
// { goal: 'weight_loss', interests: ['yoga', 'running'] }

Return	Type	Description
`responses`	`Record<string, VariableValue>`	All response key-value pairs
