countryCountryCodeVereistStelt het API-pad in

The country to perform address lookups in.

authKeystringAPI-parameter

Your Pro6PP Authorization Key. Optional if using a proxy.

limitnumberAPI-parameter

Number of suggestions to request per batch, at most 1000. 0 uses the default.

Standaard
20
languageLanguageCodeAPI-parameter

Language code for response labels. Affects the language of returned address labels. Only applicable for BE country code.

sortSortOrderAPI-parameter

Sort mixed address and place suggestions by relevance or distance. Distance sorting requires the Infer Extended (infer::location) capability. It measures from lat and lng when provided, otherwise from the approximate location of the request IP, and sorts by relevance when neither is available.

Standaard
'relevance'
latnumberAPI-parameter

Latitude of the origin used for distance sorting, sent only when sort is 'distance'. When provided, lng must also be provided.

lngnumberAPI-parameter

Longitude of the origin used for distance sorting, sent only when sort is 'distance'. When provided, lat must also be provided.

typesInferTypes

Suggestion types to request. Omit this to preserve the address-only default.

apiUrlstring

If provided, this URL is used as the API endpoint. The query params are appended, including country in lowercase.

  • If not provided, the SDK defaults to 'https://api.pro6pp.nl/v2/infer/{country}'.
fetcherFetcher

Custom fetch implementation for network requests.

Standaard
globalThis.fetch
debounceMsnumber

The delay in milliseconds before performing the API search. Note: A lower bound of 50ms is enforced to protect API stability.

Standaard

onStateChange(state: InferState) => void

Callback triggered whenever the internal state (suggestions, loading status, etc.) updates.

onSelect(selection: AddressValue | string | null) => void

Callback triggered when an address selection completes or is cleared. Receives the AddressValue of the selected address, or its label as a string when the selection has no structured value. Receives null when the user edits a completed selection or selects a place after a structured address. Partial selections, such as a city or street, do not trigger it.

onPlaceSelect(selection: PlaceValue | null) => void

Callback triggered when a point of interest is selected, or with null when the user edits the selected place or selects an address instead.

Custom placeholder text for the input field.

inputClassstring

Additional CSS classes to add to the input element.

noResultsTextstring

The text to display when no suggestions are found.

InstantieInferJS, geretourneerd door attach

new InferJS(target, config)

Initializes the Infer logic on a target element.

target string | HTMLElementEither a CSS selector string or a direct HTMLElement.
config InferJSConfigConfiguration options for the API and UI.
valueAddressValue | nullget, set

Retrieves the current selected address value if available.

Programmatically sets the address value.

placePlaceValue | nullalleen lezen

Retrieves the current selected place value if available.

setPlace(place)→ void

Programmatically selects a place value.

place PlaceValue
destroy()→ void

Destroys the InferJS instance, removing its event listeners and added elements and clearing the input value. An input created by the SDK is removed. An existing input keeps the attributes and inputClass classes the SDK added, and the injected theme stays in the document. Attaching to the same element again destroys the previous instance automatically.
