Using the FacilMap client

The FacilMap client makes a connection to the FacilMap server using socket.io and automatically receives updates when markers, lines, the map settings, or any other part of a map is created, changed or removed. When connecting to the map using the writable ID, it it also makes it possible to make any modifications to the map that you could make through the web interface, such as creating/changing/removing markers, lines and views and changing the map settings.

One instance of the Client class represents one connection to one specific collaborative map on one specific FacilMap server. To receive markers and lines, a bbox has to be set, and only the markers and line points within that bbox will be received. The bbox can be changed (for example, if the user drags the map), which causes objects from the new bbox to be received. The Client instance will store all objects that it receives in its properties.

Note that in the methods of the client, a collaborative map will be referred to as pad. This is because the collaborative part of FacilMap used to be a separate software called FacilPad.

Setting it up

Install facilmap-client as a dependency using npm or yarn:

npm install --save facilmap-client

or

yarn add facilmap-client

or load the client directly from facilmap.org:

<script src="https://facilmap.org/client.js"></script>

The file build/client.js contains the Client class and all its dependencies. You can access the class using the global variable FacilMap.Client.

If you are using webpack, you can alternatively require the Client like this:

import Client from 'babel-loader?presets=es2015!facilmap-client';

Development

Make sure you have yarn installed. Run yarn run deps to install the dependencies and yarn run build to create the bundle in build/client.js.

Setting up a connection

let conn = new FacilMap.Client("https://facilmap.org/");
conn.setPadId("myMapId").then(() => {
	console.log(conn.padData);
}).catch((err) => {
	console.error(err.stack);
});

Using it

A detailed description of all the methods and data types can be found in API.

Using with Angular JS

Making sure $apply is called when the asynchronous methods of the Client return is easy:

let Client = require("facilmap-client");
let myAngularApp = angular.module("myAngularApp", []);

angular.factory("facilMapClient", ($q, $rootScope) => {
	// We need to overload two methods to make sure that $rootScope.$apply() is
	// called when asynchronous methods return
	class FacilMapClient extends Client {
		_emit(eventName, data) {
			return $q.resolve(super._emit(...arguments));
		}
	
		_simulateEvent(eventName, data) {
			return $rootScope.$apply(() => {
				return super._simulateEvent(...arguments);
			});
		}
	}
	
	// We can use the overloaded class like the regular one
	return new FacilMapClient("https://facilmap.org/");
});

angular.run((facilMapClient) => {
	facilMapClient.setPadId("myMapId").then(() => {
		console.log(facilMapClient.padData);
	}).catch((err) => {
		console.error(err.stack);
	});
});
