Query Param Hooks

Hooks for reading URL query parameters (query.* namespace).

Every query parameter must be declared in queryParams in your appfunnel.config.ts before it will be captured from the URL. The five UTM parameters (utm_source, utm_medium, utm_campaign, utm_content, utm_term) are included by default — all others must be explicitly declared.

`useQueryParam(key)`

Read a single URL query parameter by name. Read-only.


const utmSource = useQueryParam('utm_source')

Return	Type	Description
`value`	`string`	Query parameter value (empty string if not present)

`useQueryParams()`

Read all URL query parameters as a flat object. Only re-renders when a query.* variable changes.


const params = useQueryParams()
// { utm_source: 'google', ref: 'homepage' }

Return	Type	Description
`params`	`Record<string, string>`	All query parameter key-value pairs
