Trafficmaps

[KirAsh4]

@shgmongohh, I do not. However, Google is your friend. W3Schools is another.

@tyho, there is a huge difference on how you use the Google Maps API to display a map in a browser, compared to how it needs to be done within the core module system of MagicMirror. MagicMirror isn’t simply a browser that displays HTML or JS … it processes the information fed to it, and that information needs to be in a very specific format to be processed successfully. This is why my recommendation to you was to try and understand the core system first, before you try to integrate something as complex as any of the Google APIs, not just the maps one.

in basics i untherstand the concept of node.js. It’s not like a website where you can load a page from a server. node js is basicly the server that creates and push the website when requested.

I will have to learn some more i guess ^^ I always want to go the fast way :P

[tyho]

I have to give up on this one. I found topics where people said its really hard to call the google maps js api in nodejs environment. Even just only displaying a map. That explains why there are no codes of others available to learn from.
I think i just go for the static map (image) url from the google api. But that won’t be a trafficmap couse that’s not possible.
@KirAsh4 Thanks for your motivating words and help. I will expand my notification module for the voicecontrol module from alexyak96, that is working very well!. Maybe i come back later on this one when i got more knowledge or if someone else made a basic map module that i can expand for traffic ^^.

More importantly, It’s not just a Node.js environment. It’s a frontend framework that does most of the UI work for you.

[tyho]

@MichMich yea i noticed that. But it’s still too hard for me to implent a simple javascript like google maps js api. The js code is simple to untherstand but i still need the node-modules that are used by it. And it’s still not as straight forward because node is server sided. I got the idea but not the knowledge.

[tyho]

Does anybody know what modules i have to use to get the maps js api working? Angular? Async? Express? Or somerhing like a google api module?

[MichMich]

@tyho you don’t need no modules. The only thing that is important is that you fully understand the MagicMirror framework. As told, the best way to learn this, is by start building a real simple module.

[KirAsh4]

You could also look at what’s already been done, such as https://github.com/moshen/node-googlemaps …

[tyho]

@KirAsh4 i’ve seen that one ;) but i don’t know where to start. That module uses some different dependeties that are already in magicmirror. As suggested by @MichMich i should first build a simple module. (Well i’ve build one already that works very well but i don’t know if thats the right way of writing code and if it’s fail proof). Anyway i will keep try some stuff. I die got a map on my mirror with static map. But i want this trafficlayer. So i need to use the javascript api.
On the mirror i can already see what i have to wear, where i have to go (appointments), and what happend in the world before i go. Wouldn’t it be cool if we can display traffic info and map before we leave to work. :D

anyone who want to show a google staticmap on there mirror. Here is the code:

/* global Module */

/* Magic Mirror
 * Module: staticmap
 *
 */
  
Module.register("staticmap",{
	defaults: {
		center: "new york",
		zoom: 14,
		mapwidth: 600,
		mapheight: 500,
		highway: "on",
		arterial: "on",
		local: "on"
	},

start: function(){
	Log.info('Starting module: ' + this.name);
},



	getDom: function() {
		var wrapper = document.createElement("div");
		var img = document.createElement("img");
		img.src = "https://maps.googleapis.com/maps/api/staticmap?center=" + this.config.center + 
		"&zoom=" + this.config.zoom +
		"&size=" + this.config.mapwidth + "x" + this.config.mapheight + 
		"&maptype=roadmap" +
		"&style=feature:road.highway|visibility:" + this.config.highway +			  
		"&style=feature:road.arterial|visibility:" + this.config.arterial +	
		"&style=feature:road.local|visibility:" + this.config.local + 
		"&style=feature:road|invert_lightness:true|saturation:-100|weight:1|lightness:1" +
		"&style=feature:administrative|invert_lightness:true|saturation:-100|weight:1|lightness:1|visibility:on" + 
		"&style=feature:poi|invert_lightness:true|weight:1|saturation:-100|lightness:1|visibility:on" +
		"&style=feature:transit|invert_lightness:true|saturation:-100|lightness:1|weight:1|visibility:on" +
		"&style=feature:landscape|invert_lightness:true|weight:1|saturation:-100|lightness:1|visibility:on" +
		"&style=feature:water|invert_lightness:true|weight:1|saturation:-100|lightness:1|visibility:on" +
		"&style=feature:road|element:labels.text.fill|lightness:100" +
		"&style=feature:road|element:labels.text.stroke|lightness:-100";
		img.width = this.config.mapwidth;
		img.height = this.config.mapheight;
		wrapper.appendChild(img);
		return wrapper;
	}
});

Instead of Google, you could also use Microsoft’s Bing service to get a map with accidents:

Good one! i will see if i can get something working.

What i try to do is:

• Get a map with a route to my work.

• Get traffic status along this route.

• Style the maps so it’s nice visable through the mirror. (black/white maps and red lines/triangels for traffic jam.

• Abillity to switch route with @alexyak voicecontrol module. (work me = to amsterdam) (work girlfriend = to utrecht)

This are a few wishes. But i am happy already if i get the first two working ^^ i am not skilled at node and js at all… any help is appreciated.

[tyho]

ok just for the record. if i got the most simple maps js api code:

<!DOCTYPE html>
<html>
  <head>
    <title>Simple Map</title>
    <meta name="viewport" content="initial-scale=1.0">
    <meta charset="utf-8">
    <style>
      html, body {
        height: 100%;
        margin: 0;
        padding: 0;
      }
      #map {
        height: 100%;
      }
    </style>
  </head>
  <body>
    <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 src="https://maps.googleapis.com/maps/api/js?key=YOUR_API_KEY&callback=initMap"
    async defer></script>
  </body>
</html>

can i just create a module with:
var x = document.getElementById("map").id;for the div?
var x = document.createElement("SCRIPT");for the script tags? (w3schools said it supports async and defer)
and then create 2 functions. 1 for the src api url that i can callback within the script tags and 1 for the initMap that i can callback after the scr url?
Is this good thinking or is it not that simple?

[tyho]

i am feeling close but also so far far away ^^ ghehe

Module.register("trafficmaps",{
	defaults: {
	},

	start: function(){
		Log.info('Starting module: ' + this.name);
	},

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


	getDom: function() {
		var wrapper = document.createElement("div");
		var mapdiv = document.getElementById("map");	
		wrapper.appendChild(mapdiv);
		var maps = document.createElement('script');
		maps.type = 'text/javascript'; maps.async = true; maps.defer = true;
		maps.src="https://maps.googleapis.com/maps/api/js?key=YOUR_API_KEY&callback=" + this.initMap;
		wrapper.appendChild(maps);
		return wrapper;
	}
});

This script hangs… and it prevents other modules loading…

[tyho]

I am also trying the bing option seperately but also no result. I’ll keep trying. I am wondering why there arn’t any scripts on the web yet. I think this is for there experts among us ^^

[tyho]

i found a example of bing maps: https://github.com/jwalgran/bing

Anyone who can turn this into a module? I already tried but no succes :(

[alexyak]

@tyho so what exactly you’re trying to implement? What would be a use case here for the MM?

[tyho]

@alexyak What i tried to create is a map view from my home to my work. With on this map the trafficjam/delay. (google can do with the red orange green lines and bing with the triangles). With this map i can see in the morning when i wake up, if i have to leave earlier because of traffic jam. This where my first thoughts for the module. (but with my ms frontpage experience i can’t get this working ^^)

As a second thought i had in mind to use your voice module (or facial recgnition module) to switch between my map and that of my girlfriend. So another map is loaded.

In the google static map that i already created there is no option to add a traffic layer.

In both google maps and bing maps there are style options to make the map black and white for better display. and for example the traffic jam could be red displayed.

[alexyak]

@tyho alright, now I understand your requirements… I can’t promise, but will try to have a look at this over a few coming days.
