#01 - Create Map With Esri ArcGIS JS Api

ArcGIS JS Api is a javascript library to develop web mapping application. I will describe how to create a map in website in this first post.

What Will I Learn?

We will learn how to add map in our website.

• How to add Esri ArcGIS JS Library in our project.
• How to create 2D map.

Requirements

You can use any operating system and any ide or editor. I will use "Windows PC" and "Visual Studio Code". And i will use ESRI ArcGIS JS Library from web. But you can install library using bower from github repository.

• Windows 10 Operating System
• Visual Studio Code Editor
• ESRI ArcGIS JS API version 3.23
  -Basic knowledge of HTML
  -Basic knowledge of JS
  -Basic knowledge of CSS
  -Basic knowledge of Dojo Toolkit

Difficulty

• Basic

Contents

1. Creating Files

We will create "index.html" into main folder, "main.js" into "js" folder and "main.css" into "css" folder.

| -- ESRI ArcGIS JS API 3.23
| -- | -- js
| -- | -- | -- main.js
| -- | -- css
| -- | -- | -- main.css
| -- | -- index.html

1.1 index.html

We will create basic html file and add ESRI ArcGIS JS API stylesheet and javascript library into "head" tag.

// ESRI ArcGIS JS API  stylesheet and javascript library.
<link rel="stylesheet" href="https://js.arcgis.com/3.23/esri/css/esri.css">
<script src="https://js.arcgis.com/3.23/"></script>

We are adding files that we created into "head" tag.

<link rel="stylesheet" href="css/main.css">
<script src="js/main.js"></script>

And last,we are adding "div" that has map id, element for map into "body" tag.

<div id="map"></div>

1.2 /js/main.js

We will create basic javascript file using Dojo Toolkit and add map to website.

// Adding map library.
require(["esri/map", "dojo/domReady!"], function (Map) {
    // Creating map instance.
    // First parameter div id for map.
    // Second parameter map options.
    var map = new Map("map", {
        // Adding map center longitude and latitude coordinate.
        center: [28.954472, 41.051835],
        // Adding zoom level.
        zoom: 10,
        // Adding map style.
        basemap: "hybrid"
    });
});

Ok, that is it. We can see map, if we run index.html.

1.3 /css/main.css

We created map but we can want to change our map style. We can use css for this. I will change my map div full screen.

html, body, #map {
    height:100%;
    width:100%;
    margin:0;
    padding:0;
}

2. Result

We learned how to create map with ArcGIS JS API in web.
