Ottieni una chiave API e attiva il kit UI di Places
Prima di utilizzare l'UI Kit di Places, devi:
- Crea un progetto Cloud con un account di fatturazione.
- Attiva il kit UI di Places.
- Ottieni una chiave API.
Per scoprire di più, vedi Configurare il progetto Google Cloud.

Carica le librerie richieste
Per caricare le librerie che supportano Places UI Kit, carica prima l'API JavaScript di Maps aggiungendo il caricatore di bootstrap in linea al codice dell'applicazione, come mostrato nello snippet seguente:
<script>
(g=>{var h,a,k,p="The Google Maps JavaScript API",c="google",l="importLibrary",q="__ib__",m=document,b=window;b=b[c]||(b[c]={});var d=b.maps||(b.maps={}),r=new Set,e=new URLSearchParams,u=()=>h||(h=new Promise(async(f,n)=>{await (a=m.createElement("script"));e.set("libraries",[...r]+"");for(k in g)e.set(k.replace(/[A-Z]/g,t=>"_"+t[0].toLowerCase()),g[k]);e.set("callback",c+".maps."+q);a.src=`https://maps.${c}apis.com/maps/api/js?`+e;d[q]=f;a.onerror=()=>h=n(Error(p+" could not load."));a.nonce=m.querySelector("script[nonce]")?.nonce||"";m.head.append(a)}));d[l]?console.warn(p+" only loads once. Ignoring:",g):d[l]=(f,...n)=>r.add(f)&&u().then(()=>d[l](f,...n))})({
key: "YOUR_API_KEY",
v: "weekly",
// Use the 'v' parameter to indicate the version to use (weekly, beta, alpha, etc.).
// Add other bootstrap parameters as needed, using camel case.
});
</script>
Quindi, utilizza l'operatore await
per chiamare importLibrary()
all'interno di una funzione async
, come segue:
// Import the Places Library for PlaceDetailsElement and PlaceSearchElement
const {PlaceDetailsElement, PlaceSearchElement} = await google.maps.importLibrary('places');
// Import the Elevation Library for ElevationElement
const {ElevationElement} = await google.maps.importLibrary('elevation');
