How to get postal code back from search results?

[tbaustin]

I'm not seeing a postal code/zip code coming back from the search results?

That depends on the provider that you're using. For openstreetmap, you might want to include the addressdetails in your response.

Basically, you need to check the additional parameters that your provider supports (in the docs of that provider), and than pass that option to the constructor.

https://smeijer.github.io/leaflet-geosearch/providers/openstreetmap#optional-parameters

const provider = new OpenStreetMapProvider({
  params: {
    'accept-language': 'nl', // render results in Dutch
    countrycodes: 'nl', // limit search results to the Netherlands
    addressdetails: 1, // include additional address detail parts
  },
});
