Add some action to your Map apps!

I’ve been experimenting with ways to add small, focused, utility actions to my maps. This could be something like clicking on the map and doing a buffer analysis, or double-click and query some data, and so on, I think you get the idea. I’ve called these behaviors, I’ve seen them referred to as Map Actions…


Animate a drawer in ArcGIS JSAPI 4

Popups, UI, and HAX!

The recent videos have covered an array of topics! Popups I’ve had some interests about working with Popups in the ArcGIS API for JavaScript, so you can check out these videos! The Popup is probably the most widely used widget in applications. It’s the first point of entry to get details about data displayed on…


Yet another application ArcGIS JSAPI starter kit

I know, I know. Lately, I’ve been working on this little starter kit in my spare time. I started it because I’ve gotten a few questions about how to build an app with the ArcGIS API 4 for JavaScript. I’ve used this application in some demos, and I’ve gotten requests to share it. So I…


How to void your ArcGIS API for JavaScript Warranty!

Code coverage in your apps

Ok, so this post isn’t necessarily about geodev, but it’s related in that I’m sure a lot of us don’t write enough tests. I’m working on this, and I recently, for some odd reason, got really into code coverage and tooling. Using it as a tool to help guide me to focus on writing my…
