const tileUrl = 'https://{s}.tile.openstreetmap.org/{z}/{x}/{y}.png';
const tiles = L.tileLayer (tileUrl, {attribution});
tiles.addTo (mymap)

export default {
  name: 'AppMap',
  data () {
    return {
      msg: 'Welcome to Your Vue.js App'
    }

<!-- Add "scoped" attribute to limit CSS to this component only -->
<style scoped>
#AppMap {
