CartoDB with ArcGIS API for JavaScript

When it comes to storing spatial data in the cloud, you have a handul of options. If you’re using Esri tech, there’s ArcGIS Online. Or maybe you’re rolling your own PostGIS on AWS or OpenShift or elsewhere. If you’re a fan of PostGIS, I’d highly recommend CartoDB. CartoDB is great for storing data in a…

turfjs

Exploring new Turf

TurfJS is a relatively new library that allows you to do spatial analysis in the browser. Turf is great because it works with GeoJSON. This means it’s suited very well to work with Leaflet. So well that it’s even included as a plugin for Mapbox now. I’ve used some of Turfs capabilities in a couple…

EsriJS with ReactJS

I really enjoy experimenting with frameworks and libraries. Even back when I was doing ActionScript dev, I was a big fan of Swiz and Robotlegs. When it comes to JavaScript frameworks, I try to give each one a shot, from Backbone to Knockout and Angular. One library I have really grown to enjoy has been…

PureScript with Leaflet Experiments

Not another damn JavaScript compiler Yeah yeah, I know. For a long time, I really enjoyed using CoffeeScript and I have spent quite a bit of time learning ClojureScript.

Using xstyle with ArcGIS API for JavaScript

arcgis javascript api bootstrap

Dojo Bootstrap with ArcGIS JavaScript API

If you use the ArcGIS JavaScript API, have you tried Bootstrap? It’s a great way for developers to get a decent looking website up and going pretty quickly that doesn’t look like total crap. It has some handy components, however they are dependent on jQuery because everyone uses jQuery, didn’t you know that? Bootstrap Map…



dojo router

dojo router for your Esri JavaScript Maps

Part of the rage in building single page applications is the ability to do all your page routing on the client. Angular has the $routeProvider, Backbone has a solid router, Ember has a great routing system in place, and although React isn’t an all-in-one framework, there is a fantastic routing library available for it. Now,…
