It’s that special holiday we all look forward to this time of year, it’s GIS Day! Now please hold back your excitement. If you are a GIS pro, you are probably lounging around the house enjoying your holiday off. I’ll be hanging out at the LA County GIS Day event most of the day hoping…

10 Things I learned writing ArcGIS Web Dev

So it’s been almost two years now since I took on the challenge of writing the ArcGIS Web Dev book from Manning Publications. Recently I made myself a list of 10 things I learned in the process. I didn’t think I could write Ok, that might be a horrible thing to say considering I have…




Leaflet.Control, transducers and es6

Hacking away I haven’t hacked away at using Leaflet in a while, but I’m looking at doing some pretty extensive Leaflet.Control development down the line so I needed some practice. I also wanted to play around with Transducer.js which is a JavaScript port of Clojure’s Transducers. To learn more about Transducers, go watch this video…




Some fun with Esri JS API and RxJS

What the… So I get pretty bored. For the past year or so I’ve been learning some functional programming stuff, and like most things it has snowballed into tons of little side projects and experiments. A few months ago I attended this online workshop from FrontendMasters and it totally melted my brain. I highly recommend…




Quick Tip: Save last location on map reload

I’d like to… I recently had a need in an ArcGIS JS project to save a maps last location when the user closed the browser so that it would return that location when they returned to the application. After a little trial and error, I think I came up with a pretty good solution. Quick…




Esri ClusterFeatureLayer

Too many damn points If you have ever worked with a somewhat large amount of points in a web mapping application, in particular with the ArcGIS API for JavaScript, you know the pain points it can take to display that much data on a map. It could be five-thousand, fifty-thousand or a one-thousand, depending on…




2014 Goals. Growth and Challenges

2013 turned out to be a pretty interesting year. Looking back at my goals for the year, I think I’ve done a pretty good job. I’ve had some new challenges, took on some new work and sharpened my current skills. What I got done I’ve really picked up the pace in terms of my JavaScript…




Modularized ArcGIS JS, overboard.

I got problems Sometimes I’m not sure what I enjoy doing more, writing code or working with build tools. I recently went on a caffeine fueled bender trying to figure out how to best solve a problem that I run into all too often. Managing changes and fixes in my codebase along all my projects….




Get ArcGIS Web Development Half Off

Today is a pretty sweet deal at Manning Publications where you can get all ebooks for half price using code dotd1216au. This of course will also work for my book, ArcGIS Web Development. Other titles I would recommend are PostGIS In Action 2nd Edition and Location-Aware Apps. Thanks for looking!




RequireJS for single-file builds: revisited.

Someone recently started a github repo using RequireJS to build their ArcGIS JavaScript applications. This piqued my interest as it’s something I had done in the past, but at some point r.js or node didn’t work properly together anymore with my build file. Rather than fuss with it, I moved on to using Grunt to…
