Maps App JavaScipt

This repo provides an example app called Maps App that can be used as as starter for your organizations mapping app built with ArcGIS API 4 for JavaScript. You can use the Maps App as is, or extend it using the ArcGIS API for JavaScript.


  • Dynamically switch basemaps
  • Place search
  • Directions
  • Sign into an ArcGIS account
  • Service Worker
  • AppCache
  • manifest.json - to add as button to home screen
  • default icons

This application takes advantage of numerous technologies for development purposes. It utlizes webpack to compile and bundle the application code and other files. It is written in TypeScript and provides examples on how to create custom widgets using the ArcGIS API 4 for JavaScript.

This application also uses Workbox for Webpack to set up service workers for the application to cache application code and files, as well as uses an appcache fallback for Internet Explorer, Edge, and Safari.

Intern is used for all unit tests and code coverage.

Feel free to use this project as a starting point for your own applications!

Detailed Documentation

Read the docs for a detailed explanation of the application, including its architecture and how it leverages the ArcGIS platform, as well as how you can begin using the app right away.


Clone the repo and run npm install.

  • NOTE FOR WINDOWS USERS - You will need to install the Windows-Build-Tools to compile npm modules for this project. npm install --global --production windows-build-tools

  • npm start - compile application and run it in a local server at http://localhost:8080/.

  • npm run build - compile application for deployment.

  • npm test - run unit tests with local chrome driver.

  • npm run serve - Run a production build of the application, but serve it up locally to see how the built app will behave.

Use npm run serve to full test that Service Workers are working correctly with webpack-dev-server self signed certifcates. Refer to this article on how to run Chrome with proper flags enabled for development purposes.

  • Once you've registered your version of the maps-app, grab a copy of the client id from the registration and set the client id in the applications src/app/config.ts file. You will also want to provide the Portal URL for your Organization, such as "https://<MY-ORGANIZATION>". You can also provide your own WebMap or use the default one provided.
// src/app/config.ts
 * Registered application id.
 * This is needed to be able to use premium
 * services such as routing and directions.
export const appId = "<APP-ID>";

 * Users Portal URL.
export const portalUrl = ""; // default Portal URL

 * WebMap id to use for this application.
 * You can update this WebMap id with your own.
export const webMapItem = {
  portalItem: {
    // shared WebMap with Vector Tile basemap
    id: "1aab2defd7444b6790f439a186cd4a23"
  • As part of the registration process, add a redirect uri for your app. Navigate to the Redirect URIs section at the bottom of the registration page and set the redirect uri as shown for development purposes. You will also want to add a redirect uri for where your application will be deployed. This redirect uri is the default redirect for

For development purposes, you will want to add the following redirects to your Application ID:


When you deploy your application, do not use the same Application ID for development as production. You want your Application ID to only redirect to your production website.
