Overview of this book

The ArcGIS API for JavaScript enables you to quickly build web and mobile mapping applications that include sophisticated GIS capabilities, yet are easy and intuitive for the user. Aimed at both new and experienced web developers, this practical guide gives you everything you need to get started with the API. After a brief introduction to HTML/CSS/JavaScript, you'll embed maps in a web page, add the tiled, dynamic, and streaming data layers that your users will interact with, and mark up the map with graphics. You will learn how to quickly incorporate a broad range of useful user interface elements and GIS functionality to your application with minimal effort using prebuilt widgets. As the book progresses, you will discover and use the task framework to query layers with spatial and attribute criteria, search for and identify features on the map, geocode addresses, perform network analysis and routing, and add custom geoprocessing operations. Along the way, we cover exciting new features such as the client-side geometry engine, learn how to integrate content from ArcGIS.com, and use your new skills to build mobile web mapping applications. We conclude with a look at version 4 of the ArcGIS API for JavaScript (which is being developed in parallel with version 3.x) and what it means for you as a developer.

Basic steps for creating an application with the ArcGIS API for JavaScript

Now that we've got some of the basics of HTML, CSS, and JavaScript out of the way it's time to actually get to work and learn how to build some great GIS web applications! The material in this chapter will introduce you to some of the fundamental concepts that define how you create a map and add information to the map in the form of layers.

There are several steps that you'll need to follow for creating any GIS web application with the ArcGIS API for JavaScript. These steps will always need to be performed if you intend to have a map as part of your application. And I can't imagine that you wouldn't want to do that, given that you're reading this book! In a nutshell,there are several steps you need to follow:

  • Create the HTML code for the page
  • Reference the ArcGIS API for JavaScript and style sheets
  • Load modules
  • Make sure the DOM is available
  • Create the map
  • Define page content
  • Style the page
  • The entire code
