Introduction

Checkout the playlist on leafletjs from basic to advance below,

This repo contain all the basic ideas about the leaflet. I added various functionalities about the leaflet.js.

Basic

Inside this folder I added following functionalities.

Adding base map

var map = L.map("map").setView([28.2521, 83.9774], 18);
var OpenStreetMap_Mapnik = L.tileLayer(
  "https://{s}.tile.openstreetmap.org/{z}/{x}/{y}.png",
  {
    maxZoom: 19,
    attribution:
      '&copy; <a href="https://www.openstreetmap.org/copyright">OpenStreetMap</a> contributors',
  }
).addTo(map);

Adding multiple base layers

var baseLayers = {
  "OSM Mapnik": osmMap,
  Landscape: landMap,
};

L.control.layers(baseLayers).addTo(map);

Adding multiple markers

var markers = [
  ["7C6B07", -40.99497, 174.50808],
  ["7C6B38", -41.30269, 173.63696],
  ["C820B6", -41.51285, 173.53274],
];
for (var i = 0; i < markers.length; i++) {
  marker = new L.marker([markers[i][1], markers[i][2]])
    .bindPopup(markers[i][0])
    .addTo(map);
}

Adding lines on leaflet map

var polyline = L.polyline(
  [
    [-40.286, 175.796],
    [-41.281, 176.086],
    [-41.279, 175.776],
    [-41.29, 174.075],
    [-42.292, 174.788],
  ],
  {
    color: "red",
    weight: 10,
    opacity: 0.7,
    dashArray: "20,15",
    lineJoin: "round",
  }
).addTo(map);

GeoJSON

Inside this folder I added following functionalities.

Adding Geojson in map

L.geoJSON(json_data).addTo(map);

Custom Popup in Geojson
Custom style in Geojson

Geolocation

Inside this folder, I write the code to redirect the user location. It takes the user location and shows on map.

Responsive sidebar for leaflet

This is actually a plugin. This plugin can be found at leaflet-sidebar-v2

Animation Routing

Inside this folder, I use leaflet-router-machine plugin. for more information goto leaflet-routing-machine

Draw

This is also a draw plugin. This plugin supports the Drawing feature in map. There are lots of features in this plugin. The user can add the point, line, polygons, edit this layers, delete the layer etc.

Leaflet Routing Machine

This plugin is very useful for the navigation. for more goto leaflet-routing-machine. This plugin can be initiated by using

<link rel="stylesheet" href="https://unpkg.com/leaflet@1.2.0/dist/leaflet.css" />
<link rel="stylesheet" href="https://unpkg.com/leaflet-routing-machine@latest/dist/leaflet-routing-machine.css" />
<script src="https://unpkg.com/leaflet@1.2.0/dist/leaflet.js"></script>
<script src="https://unpkg.com/leaflet-routing-machine@latest/dist/leaflet-routing-machine.js"></script>

mapbox base map

In this code, I use mapbox layer as base layer. The general style for showing the mapbox layer on leaflet is

var map = L.map("map").setView([28.2521, 83.9774], 12);
var mapboxTile = L.tileLayer(
  "https://api.tiles.mapbox.com/styles/v1/{username}/{id}/tiles/{z}/{x}/{y}?access_token={accessToken}",
  {

  }
).addTo(map);

Marker Cluster

The leaflet plugin named as marker-cluster is very useful for the multiple markers. This plugin helps to manage the multiple markers on the map.
