How to implement Google Maps API in a WeWeb project?

Preparation Step: Obtain a Google Maps API key

Before you can implement Google Maps API into your WeWeb project, you'll first need a Google Maps API key. This can be obtained from Google Cloud Platform. Here's how to do it:

• Visit the Google Cloud Platform Console at https://console.cloud.google.com/

• If you don't have a Google account, you'll need to create one. If you do have one, sign in.

• After you're signed in, click "Select a project" in the top right, then "NEW PROJECT" in the top right of the modal which appears.

• Give your project a name and click "CREATE".

• Once your project is ready, select "Dashboard" from the left sidebar.

• Click "ENABLE APIS AND SERVICES" at the top.

• In the next screen, type "Maps" into the search bar and select "Maps JavaScript API".

• Click "ENABLE".

• After the API is enabled, click "Credentials" in the left sidebar.

• Click "CREATE CREDENTIALS" at the top, then select "API key".

• Your API key will be created and displayed to you. Make sure to restrict it to HTTP referrers and add the domains on which this API will be used, to prevent unauthorized usage.

Be sure to keep your API key private and secure.

Step One: Start your WeWeb project

If you haven't done so already, start your new WeWeb project or open your existing project where you want to implement Google Maps API.

Step Two: Add an HTML box to your webpage

In WeWeb, navigate to the page where you want to embed the map, and add an HTML box which will hold the map. To do this:

• Click on the "+" button on the toolbar to open the widgets catalog.

• Drag and drop the HTML box onto your page to the desired location.

Step Three: Embed the Google Maps API

In the HTML box, you're going to write the lines of code that call the Google Maps API. Here's how to do that:

• Click on your new HTML box to open the configuration options on the left sidebar.

• In the "CUSTOM HTML" field, enter the following code:

<div id="map"></div>

<script>
      var map;
      function initMap() {
        map = new google.maps.Map(document.getElementById('map'), {
          center: {lat: -34.397, lng: 150.644},
          zoom: 8
        });
      }
</script>

<script async defer src="https://maps.googleapis.com/maps/api/js?key=YOUR_API_KEY&callback=initMap"></script>

Replace 'YOUR_API_KEY' with the API key you obtained from Google Cloud Platform.

The lat and lng values in the code snippet correspond to the latitude and longitude values of the initial location that will be displayed on your map. You can change these to whatever values you need.

Step Four: Style your map

In the same "CUSTOM HTML" field, you can add some CSS to style the size and appearance of your map. For example, you could add the following lines of code to make the map fill the entire width of the screen and set a specific height:

<style>
  #map {
    height: 400px;
    width: 100%;
  }
</style>

Step Five: Save and view your map

Click on the "Preview" button at the top of the screen to save your project and view your map.

The Google Map should now be displayed on your website. You are now free to customize the map according to your needs by using different features and functionalities provided by Google Maps JavaScript API.
