This is a wrapper for the leaflet-fullscreen control to make it easy to use in Angular 8+.
This wrapper is tested against the @asymmetrik/ngx-leaflet library but it has no dependency on that library so should work without it. It does, obviously, have a dependency that leaflet is loaded.
For more detailed descriptions of how this wrapper was created : Documentation.
For detailed descriptions of how to use and worked examples : Article, Article
For an example of this working in a real site - see trackbash.
Install using npm:
npm install @runette/ngx-leaflet-fullscreen
NOTE - after version 1.0.6 - this library is built using ng-packagr and an Ivy partial comppile. This should allow compatability with any version of Angular.io after >v12.0.0 (according to the Angular docs).
Note : this package currently installs a fork of leaflet-fullscreen : @runette/leaflet-fullscreen.
This is because the root repo has not been updated with several important PRs and has not been changed for 4 years.
This library needs to be imported into the application module:
/// <reference types='@runette/leaflet-fullscreen' />
import {NgxLeafletFullscreenModule} from '@runette/ngx-leaflet-fullscreen'
imports: [
...
NgxLeafletFullscreenModule,
],Then, the control is inserted using the following directive:
<leaflet-fullscreen-control
[map]="..."
[options]="..."
></leaflet-fullscreen-control>Where map is an instance of a leaflet map and options is an object with valid options for the control.
Sometimes, Angular cannot find the correct typings. In this case, add the following directive as the first line of the .ts script:
/// <reference types='@runette/leaflet-fullscreen' />
This library integrates very easily with ngx-leaflet using the onMapReady event:
<div id='map' class="map-container" leaflet
[leafletOptions]="options"
(leafletMapReady)="onMapReady($event)"
></div>
<leaflet-fullscreen-control
[map]="map"
[options]="fullscreenOptions"
></leaflet-fullscreen-control>by adding the following to your map component:
...
import { Map } from 'leaflet';
export class OsmMapComponent implements OnInit, OnDestroy {
public map?: Map;
public fullscreenOptions: FullscreenOptions = {
position: 'topleft'
};
...
onMapReady(map: Map) {
this.map = map;
}Unfortunately - I think because the leaflet map is run outside of Angular by ngx-leaflet - the normal css encapsulation does not work and you have to load the css globally.
Add the following to the styles.css
@import "@runette/leaflet-fullscreen/dist/leaflet.fullscreen.css";For some reason yet to be found - this library does not like being built with "buildOptimizer": true, in the build environment - which is usually the default for the production environment in angular.json.
Always build with "buildOptimizer": false,.
If you want access the control's methods directly from your typescript code - this can be done with @ViewChild
Use ViewChild to access the component, for instance
@ViewChild(FullscreenControlComponent,{static: false}) fullscreenComponent: FullscreenControlComponent;The actual instance of the control can then be accessed directly as this.fullscreenComponent.control

Contributions to this repository are very welcome.
Please fork the repository and create a new branch for your changes. The branch can be built locally using
ng build ngx-leaflet-fullscreen
in the root folder of the repo. This creates an npm package in a folder called dist. This can loaded in a test app using npm install and the FQ path to the dist folder.
When your changes are complete create a Pull Request against the master. It is IMPORTANT that you change the version number in package.json AND the tag number in .github/workflows/build.yaml to the next version before the PR.
When I have accepted and merged the PR, Github actions will automatically build the new package release and loaded it both as a GH release using the version as the tag name and publish the new version on npm.
