ngeo is an open-source JavaScript library that aims to ease the development of web GIS applications based on AngularJS and OpenLayers 3. More specifically, ngeo provides Angular components, namely "services" and "directives", that can be combined together in different ways, based on the need of the application. This talk is a general presentation of ngeo. We will present some of the features provided by the library, through concrete examples. We will also present the design choices we have made, and why we have made this design choices. AngularJS, as a very popular framework, has received (severe) criticism lately. We will report on our experience with AngularJS, discuss its "good parts", and how we mitigate its "bad parts". With ngeo we define – what we think – is a good way to use AngularJS. ngeo, for example, includes guidelines for application developers, which have turned out to be key for the development of robust and high-performance applications. This talk is for anyone interested in AngularJS and OpenLayers 3. Come to this talk if you're interested to know how we use ngeo to develop applications combining AngularJS and OpenLayers 3.
