Mapbox-gl in a Vue.js single file component (Quasar-Framework)

Question

I would like to implement a Mapbox-gl-js Map within a Quasar Framework (Vue) single file component, but I do not get it working. I found some code on Googlemaps with Vue, and some stuff on Mapbox with React, and try to pull it together from that. With below map initialisation parameters I can get the map showing fine in the index.html (with the mapzen tiles), but want it in the component.

I try to follow this [ https://laracasts.com/discuss/channels/vue/google-maps-and-vue-js](link url) and then adjust it for Mapbox: proj/src/components/maplayout.vue :

<template>
    <quasar-layout>
      <h3>Map</h3>
      <div id='map'></div>
    </quasar-layout>
  </template>

  <script>
  import mapboxgl from '../app'

  export default {
    data () {
      return {}
    },
    create () {
      this.createMap()
    },
    methods: {
      createMap: function () {
        mapboxgl.accessToken = '{{yourmapboxaccestokenkey}}'
        var simple = {
          'version': 8,
          'sources': {
            'osm': {
              'type': 'vector',
              'tiles': ['https://vector.mapzen.com/osm/all/{z}/{x}/{y}.mvt?api_key=vector-tiles-{{yourmapzenapikey}}']
            }
          },
          'layers': [{
            'id': 'background',
            'type': 'background',
            'paint': {
              'background-color': '#adddd2'
            }
          }, {
            'id': 'majorroad',
            'source': 'osm',
            'source-layer': 'roads',
            'type': 'line'
          }, {
            'id': 'buildings',
            'type': 'fill',
            'source': 'osm',
            'source-layer': 'buildings'
          }]
        }

        // initialize the map
        this.map = new mapboxgl.Map({
          container: 'map',
          style: simple,
          center: [-1.83, -78.183],
          zoom: 5.5
        })
      }
    }
  }
  </script>

  <style>
  </style>

By the way, for mapbox with webpack you need certain loaders, see: [ https://mikewilliamson.wordpress.com/2016/02/24/using-mapbox-gl-and-webpack-together/](link url) But as I got Mapbox working with Webpack before (without vue), I think I have that ok. Actually I do not get any errors in the browser console (but obviously no map appears).

In the app.js file I do not know how to deal with the suggested (maybe not necessary as googlemaps needs a callback, dunno about mapbox/mapzen?!):

var App = window.App = new Vue ({
//code
})

As in Quasar initialization is done like this:

Quasar.start(() => {
  Router.start(Vue.extend({}), '#quasar-app')
})

Which I do not really get...

Any suggestions how to get this working are welcome!

I was close. This actually works:

<template>
  <quasar-layout>
  <h3>Map</h3>
  <div id='map'></div>
  </quasar-layout>
</template>

<script>
import mapboxgl from 'mapbox-gl'
console.dir(mapboxgl)

export default {
  data () {
    return {}
  },
  ready () {
    this.createMap()
  },
  methods: {
    createMap: function () {
      mapboxgl.accessToken = '{{yourmapboxaccestokenkey}}'
      var simple = {
        'version': 8,
        'sources': {
          'osm': {
            'type': 'vector',
            'tiles': ['https://vector.mapzen.com/osm/all/{z}/{x}/{y}.mvt?api_key=vector-tiles-{{yourmapzenapikey}}']
          }
        },
        'layers': [{
          'id': 'background',
          'type': 'background',
          'paint': {
            'background-color': '#bbccd2'
          }
        },
          {
            'id': 'majorroad',
            'source': 'osm',
            'source-layer': 'roads',
            'type': 'line'
          },
          {
            'id': 'buildings',
            'type': 'fill',
            'source': 'osm',
            'source-layer': 'buildings'
          }]
      }

      // init the map
      this.map = new mapboxgl.Map({
        container: 'map',
        style: simple,
        minzoom: 1.3,
        center: [-74.0073, 40.7124], // Manhattan
        zoom: 16
      })

      this.map.addControl(new mapboxgl.Navigation())
    }
  }
}
</script>

<style>
</style>

I did not change my Vue initialisation.

<template>
  <div class="hello">
    <div id='map'></div>
  </div>
</template>

<script>
import mapboxgl from 'mapbox-gl';

require('../node_modules/mapbox-gl/dist/mapbox-gl.css');

export default {
  name: 'HelloWorld',
  data() {
    return {
      apiKey: {{ your api key }},
    };
  },
  mounted() {
    this.createMap();
  },
  methods: {
    createMap() {
      mapboxgl.accessToken = this.apiKey;
      // init the map
      this.map = new mapboxgl.Map({
        container: 'map',
        style: 'mapbox://styles/mapbox/streets-v9',
        minzoom: 1.3,
        center: [-74.0073, 40.7124], // Manhattan
        zoom: 16,
      });

      this.map.addControl(new mapboxgl.Navigation());
    },
  },
};
</script>

This might help, I guess!

Answer 3

First thing I noticed: You are initializing the map before DOM is injected into the document. Instead of 'created()' method use 'ready()'.

Answer 4

Quasar is Based on Vue2 version. So ready method is deprecated so instead of that use mounted method.
