AI-generated Key Takeaways
-
To use the Places UI Kit, you must create a Cloud project, enable the Places UI Kit, and obtain an API key.
-
The Maps JavaScript API needs to be loaded using the inline bootstrap loader, including your API key and desired version.
-
Utilize the
importLibrary()
function to load specific libraries likeplaces
andelevation
for using elements likePlaceDetailsElement
,PlaceListElement
, andElevationElement
.
This page shows you how to get an API key, enable the Places UI Kit, and load the libraries that support it.

Load the required libraries
To load the libraries that support the Places UI Kit, first load the Maps JavaScript API by adding the inline bootstrap loader to your application code, as shown in the following snippet:
<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>
Next, use the await
operator to call importLibrary()
from within an async
function, as follows:
// 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');
