## Summary

- Mapify Angular - an angular library with components for the Mapify platform

The `@mapify/angular` project contains the Mapify angular components which can be used to ease the visualisation of Mapify maps and data.

## Further Documentation and Blog Posts

You can checkout the following <a href="https://www.mapify.ai/post/creating-an-angular-application-with-mapify">blog post</a> for an example on setting up an Angular App.

## General Setup

You will need to have `nodejs` and `npm` installed.

You will need a Mapify account in order to get an API Key to use when configuring the SDK and other components.

- Get your desired API Key from the Mapify console.

## Mapify Angular Lib

### Angular Lib Setup

Install `@mapify/angular` from npm:

- `npm i @mapify/angular @angular/cdk@13 @angular/material@13 --save`

then add to polyfills.ts:

- `import 'reflect-metadata';`

The Angular library requires:

- A Mapify API Key in order to access the Mapify platform. Get your API Key from the Mapify console.
- A Google Maps API Key in order to use the Google Maps services.

### Angular Lib Configuration

In order to use the Angular components provided by this library, you will need to configure the module when importing it in your app's module.

In your app's module import MapifyAngularModule with the configuration required:

```ts
import { MapifyAngularModule } from '@mapify/angular'
import { MapConfig } from '@mapify/core';

@NgModule({
   imports: [
      MapifyAngularModule.forRoot(new MapConfig(
         // Your API keys
         environment.mapifyApiKey,
         environment.googleMapsApiKey
      ))
   ]
   ...
})
export class YourAppModule { }
```

From this point onward, you will be able to use components provided in the library.

### Using the Map Component from the Mapify Angular Lib

In you component's html add the `mapify-map` component:

```html
<mapify-map [map]="map" #mapifymap> </mapify-map>
```

In your component initialize and use the MapifyClient in order to get your maps:

```ts
import { MapifyClient, Map } from '@mapify/core';

@Component({
	selector: 'app-root',
	templateUrl: './app.component.html',
	styleUrls: ['./app.component.scss'],
})
export class AppComponent implements OnInit {
	@ViewChild('mapifymap') mapifyMap: MapifyMapComponent;
	public map: Map;

	constructor() {
		const clientConfig: ClientConfig = {
			// Your API key
			apiKey: environment.mapifyApiKey,
		};
		this.mapifyClient = MapifyClient.createClient(clientConfig);
	}

	public async ngOnInit(): Promise<void> {
		// Get some maps from Mapify
		const maps = await this.mapifyClient.maps.getAllPaginated();
		if (maps?.items?.length <= 0) {
			return;
		}
		const desiredMap = maps.items[0];
		// Request the map specifically to get the full data needed to display the map
		this.map = await this.mapifyClient.maps.get(desiredMap.mapId);
	}
}
```

By updating the contents of `this.map` the Mapify map component will detect changes and react to them. By using the ViewChild `mapifyMap` we can gain access to further methods that help us manipulate the map we have provided.

For example in order to show the map use:

```ts
this.mapifyMap.showMap();
```

Or to hide the map:

```ts
this.mapifyMap.hideMap();
```

Or to query the map's visibility:

```ts
this.mapifyMap.isMapVisible();
```

In order to center the map use:

```ts
this.mapifyMap.centerMap();
```

> **NOTE:**
> In order to be able to manipulate the map, you will need to wait for the map to be set in the component. For example, you will not be able to toggle the map in the same `ngOnInit` method in which you changed the content of `this.map`. This is because at that point no changes have been detected yet, thus only in the following cycles will the component render the map data provided.

In order to start the map with layers visible/centered there are two approaches you can choose from:

<b>onMapReady</b>

The first approach is to send a handler to the mapReady event emitter, that toggles the map visibility and centers the map once the map is ready.

Example usage:

```ts
export class AppComponent implements OnInit {
   ...

   // Define the method in your component
   public onMapReady() {
      this.mapifyMap.showMap();
      this.mapifyMap.centerMap();
   }
}
```

```html
<mapify-map [map]="map" (mapReady)="onMapReady()" #mapifymap> </mapify-map>
```

### Further Map Configuration

The `mapify-map` component can be further configured. Optional inputs include:

- googleMapsMapOptions
- height
- width

The `googleMapsMapOptions` gives control of the base map and its properties. For more information on this interface check Google's documentation [here](https://developers.google.com/maps/documentation/javascript/reference/map#MapOptions).

The `height` property allows the height of the map container to be defined. By default it is set to `'100%'`. This string should reflect a CSS string's format to apply to the map's container's height style.

The `width` property allows the width of the map container to be defined. By default it is set to `'100%'`. This string should reflect a CSS string's format to apply to the map's container's width style.

#### Example

In you component's html add the `mapify-map` component:

```html
<mapify-map
	#mapifymap
	[map]="map"
	[googleMapsMapOptions]="googleMapsMapOptions"
	height="height"
	width="width"
	(mapReady)="onMapReady()"
>
</mapify-map>
```

In your component initialize and use the configurations:

```ts
...
export class AppComponent implements OnInit {

   @ViewChild('mapifymap') mapifyMap: MapifyMapComponent;
   public map: Map;
   public height: '500px';
   public width: '500px';
   public googleMapsMapOptions: google.maps.MapOptions = {
      backgroundColor: '#2B2B2B',
      zoomControl: false,
      scrollwheel: true,
      disableDoubleClickZoom: true,
      fullscreenControl: false,
      mapTypeControl: false,
      streetViewControl: false,
      maxZoom: 20,
      minZoom: 1,
      zoom: 3,
   }

   constructor() {}
   ...
}
```
