JavaScript Debugging Tips Part II – Google Chrome and the Console Tab

This blog post is the 2nd in a series of JavaScript debugging tips and tricks to help you on your way. See JavaScript Debugging Tips Part I – Google Chrome and the Network Tab for our first segment.


The most enjoyable part of any programming assignment is right near the beginning when you sit down with a pile of tools and resources and start hammering away at raw clumps of code. The more difficult part comes when you attempt to launch the application, only to watch that tightly-written code unravel into multiple late nights staring at a computer screen. However, all is not lost, as we have an excellent recommendation for you, which is the subject of this blog: the Console tab inside your favorite browser’s Developer Tools. Continue reading

Getting Comfortable with JavaScript API 4.0

Now that the ArcGIS API for JavaScript 4.0 has been released for a couple of weeks, this is an excellent opportunity to take a walk through some of the new syntax and functionality. This blog will go through a sample 3D application focusing on the Search widget. You can follow along with the sample code from the Esri Developer Support GitHub repository, and run the hosted sample here: View it Live.

Functionality-wise, the app displays a 3D map with four widgets: Search, Zoom, Compass, and Attribution. By default, the View includes the latter three widgets, as described in the documentation. If you’re not familiar with the 4.x changes, all mapping apps contain a map and a view. The map holds the data, and the view contains the visualization information for that data. In other words, the map is the subject, and the view is the camera; complete with filters, modes, and settings. All 2D apps will have MapViews, and 3D apps will have SceneViews (note: the term ‘scene’ indicates three dimensions across ArcGIS). The same applies for maps from ArcGIS Online and Portal for ArcGIS: a WebMap is 2D, and a WebScene is 3D.

Google Chrome 51 Issues when Logging in to Portal for ArcGIS, ArcGIS Online, or Custom Apps

Update, 2 June 2016: Google Chrome 51.0.2704.79 was just released; it fixes the change that caused a blank screen for ArcGIS Online, Portal for ArcGIS, and applications built with the ArcGIS API for JavaScript. If you are affected by this, please click the Customize and control Google Chrome button and navigate to “Help > About Google Chrome” to force an update check and upgrade to this latest patch level.

The previous version was 51.0.2704.63, and the fixed version is 51.0.2704.79.

Update, 27 May 2016: KB 13156 has been published on the Support website to provide additional information about this issue.

———————

Google released an update to Google Chrome (version 51), which was pushed out to the public on Wednesday, May 25th. Unfortunately, this update included a change that impacts anyone using Google Chrome to access ArcGIS Online or Portal for ArcGIS versions 10.3, 10.3.1, 10.4, or 10.4.1.

This change impacts many apps built on the ArcGIS API for Javascript (versions 3.8 – 3.16), several subsets of custom apps built by users, partners, and Esri Professional Services (for example, any app that uses the feature table or an analysis widget), and, most notably, the “home app” in ArcGIS Online and Portal for ArcGIS.

You may be seeing a screen similar to this after logging in: a blank screen with few or no elements.

What you can do:

If you are using Google Chrome to access ArcGIS Online, the above listed Portal for ArcGIS versions, or apps built with the above-listed versions of the ArcGIS API for JavaScript, please turn off auto-update in your Chrome browser now. If Chrome was updated, you will need to temporarily use another browser (such as Internet Explorer or Mozilla Firefox) until patches have been released.

What Esri is doing:

  • The ArcGIS Online team is preparing fixes that will go live this evening.
  • We are still working on a solution for Portal for ArcGIS.
  • Developers using the hosted version of the JavaScript API are unaffected, as it has already been patched.
  • We are working on a solution for JavaScript API developers that use either a custom build of the API or use it locally.

We will provide updates at the top of this blog post regarding Portal for ArcGIS and ArcGIS API for JavaScript as soon as we have more information. A technical article has been released for this issue, KB 13156, which provides some additional detail about this problem.

If you have run into any problems as a result of this bug that impact your workflows, please contact Esri Support Services at 1-888-377-4575.

Supporting the First Esri Intern Hackathon

On the weekend of August 1st, the Esri summer interns came together to participate in a hackathon hosted in the Esri café. The weekend was designed to encourage innovation through the rapid creation of applications; the event was extremely successful. One of most interesting aspects of the hackathon was watching the diversity within each team harmonize to improve the overall quality of the final products. Each team included at least one developer to write the code and several other members from Marketing, Support Services, Professional Services, and other Esri departments to help with creative design, the use of GIS, and the delivery of the final presentation.

Setting up a Proxy

A proxy page stands between a server and an application. By using a proxy, you allow an application to authenticate on your behalf, bypassing a challenge and accessing secured services inside of an application. While the token is hidden, an application can access secured services with token-based authentication; a proxy handles massive post requests over 2,048 characters. Additionally, you can use a proxy when a resource and an application are on separate domains, as well as when cross-origin resource sharing (CORS) support is unavailable.
