Page Summary
-
This example demonstrates how to integrate an Autocomplete widget into a Google Map, allowing users to search for and select locations.
-
Upon selection, the map adjusts its view to center on the chosen location and displays an information window with details like name and address.
-
The sample code is provided in both TypeScript and JavaScript, with CSS for styling the map and Autocomplete elements.
-
The example leverages the Google Maps JavaScript API and requires an API key for functionality.
-
Developers can clone the sample code repository and run it locally using Git and Node.js.
This example shows you how to add an Autocomplete widget to a Google map.

Git and Node.js are required to run this sample locally. Follow these instructions to install Node.js and NPM. You will also need a Google Maps API key.
The following commands clone the repository, install dependencies, and copy the environment file.
git clone https://github.com/googlemaps-samples/js-api-samples.gitcd js-api-samplesnpm icp .env.template .env
Once you copy the environment file, make sure to open the .env file and replace <Insert your own development API key here> with your actual API key before starting the sample.
cd samples/place-autocomplete-mapnpm start
