ngeo is a JS library that aims to ease the development of applications based on AngularJS and OpenLayers 3.
More specifically, ngeo is a collection of AngularJS Directives and Services useful for developing applications combining AngularJS and OpenLayers 3.
Through the Directives, Services and examples it provides, ngeo defines a specific way to combine Angular and OpenLayers 3 in an application.
ngeo uses Closure Tools: the JavaScript code of ngeo uses Closure Library, and it is checked and compressed using Closure Compiler.
If you use ngeo we recommend that you also use Closure, because this is the way we design and use ngeo at Camptocamp. But using Closure is not mandatory: standalone builds of ngeo can be created.
