GSR Usage¶
Currently basic FeatureServer and MapServer functionality work. Each GeoServer workspace is considered an ArcGIS® “service” for the purposes of the API. ArcGIS® URLs look like this in GeoServer:
http://localhost:8080/geoserver/gsr/services/topp/MapServer/ http://localhost:8080/geoserver/gsr/services/topp/FeatureServer/
Where topp is the workspace name.

CORS¶
When using the official JS API, CORS detection does not work correctly. You will need to add your server manually to the list of CORS enabled servers:
require(["esri/config"], function (esriConfig) {
esriConfig.request.corsEnabledServers.push("localhost:9191");
});
CORS support also needs to be enabled on the server. Without these settings, it will attempt to use JSONP, which may not be as well supported.
For information on enabling CORS in GeoServer, see here.
Web Mercator Spatial Reference¶
The official APIs use Spatial Reference 102100 as Web Mercator. In order for this to work, add the following custom projection to your data_dir/user_projections/epsg.properties file:
102100=PROJCS["WGS 84 / Pseudo-Mercator",GEOGCS["Popular Visualisation CRS",
DATUM["Popular_Visualisation_Datum",SPHEROID["Popular Visualisation Sphere",6378137,0,
