What is Angular Google Maps and How to Install It

Google Maps has become an essential tool for many web applications, allowing users to visualize locations, routes, and a variety of map-based services. When building Angular applications, integrating Google Maps can be done seamlessly with the help of the Angular Google Maps package, which simplifies working with Google Maps by providing native Angular components.

What is Angular Google Maps?

Angular Google Maps is a package developed by the Angular team that enables easy integration of Google Maps within Angular applications. It provides a collection of Angular components, such as <google-map>, <map-marker>, and others, to allow for the easy embedding and manipulation of Google Maps features. These components simplify the complex process of interacting with Google Maps' extensive JavaScript API, making it more intuitive for Angular developers.

With Angular Google Maps, you can:

  • Display interactive maps.
  • Customize the map with markers, info windows, and overlays.
  • Control map properties such as zoom, center location, and map types.
  • Create advanced features such as drawing routes, polygons, or circles.

Why Use Angular Google Maps?

  • Simplified Integration: It abstracts much of the complexity behind the Google Maps API and wraps it in easy-to-use Angular components.
  • Native Angular Support: As an Angular package, it works seamlessly with Angular's data binding, templating, and component structure.
  • Customizable: You have full control over the appearance and functionality of the map, including zoom levels, map type, marker placement, and more.
  • Maintained by Angular Team: It is developed and maintained by the Angular team, ensuring compatibility and regular updates with Angular releases.

How to Install Angular Google Maps

Setting up Angular Google Maps in your project is simple. Follow these steps to get started:

Step 1: Install the Angular Google Maps Package

First, open your terminal and navigate to your Angular project. Then run the following command to install the Angular Google Maps package:


npm install @angular/google-maps


This command will download and install the necessary components and dependencies for integrating Google Maps into your Angular app.

Step 2: Import the GoogleMapsModule

After installation, you need to import the GoogleMapsModule into your app's main module (app.module.ts). This module provides the Google Maps components that you can use in your application.

Here’s how to import it:


import { NgModule } from'@angular/core'; 
import { BrowserModule } from'@angular/platform-browser'; 
import { AppComponent } from'./app.component'; 
import { GoogleMapsModule } from'@angular/google-maps'; 
@NgModule({ declarations: [ AppComponent],
imports: [ BrowserModule, GoogleMapsModule],
providers: [],
bootstrap: [AppComponent] })
exportclassAppModule {}


By importing GoogleMapsModule, you will now be able to use Angular’s Google Maps components across your application.

Step 3: Add the Google Map in Your Template

Next, you can add a Google Map to your Angular component's template by using the <google-map> component. Here’s an example of how you can add it to the HTML template:

<!-- map.component.html -->
<google-map
  height="400px"
  width="100%"
  [center]="center"
  [zoom]="zoom"
></google-map>

This component will render a map with a specified height, width, center location, and zoom level.

Step 4: Configure Your Map in TypeScript

In your component's TypeScript file (map.component.ts), you need to define the center and zoom properties that are bound to the map:

import { Component } from '@angular/core';

@Component({
  selector: 'app-map',
  templateUrl: './map.component.html',
  styleUrls: ['./map.component.scss']
})
export class MapComponent {
  center: google.maps.LatLngLiteral = { lat: 37.7749, lng: -122.4194 };  // Default center (San Francisco)
  zoom = 12;  // Default zoom level

  constructor() {}
}

The map will now display with the specified center and zoom level, and you can further customize it with markers, shapes, or any other features you need.


Step 5: Obtain a Google Maps API Key

To use Google Maps, you need an API key from Google Cloud Platform.


Once you have your API key, add it to the index.html file of your Angular project:

<!-- index.html -->
<script src="https://maps.googleapis.com/maps/api/js?key=YOUR_API_KEY"></script>
