Showing a single Feature

[GB11111]

Hello - The code works great for a FeatureCollection, but it apparently doesn't accept a single Feature. E.g. the following is not accepted:

{
"type": "Feature",
"geometry": {
"type": "Point",
"coordinates": [125.6, 10.1]
},
"properties": {
"name": "Dinagat Islands"
}
}

Is this by design?

Regardless, the code can be modified to handle a single Features by doing the following:

In _getGeoJson: function (geojson), change to

        if (geojson.type !== "Feature" && (geojson.type !== "FeatureCollection" || !geojson.features)) {
            console.error("GeoJsonLayer Error: Invalid GeoJSON Feature or FeatureCollection. Check url or data structure.");
            return;
        }

In _addGraphics: function (arcgisJson), change to

       if (arcgisJson.constructor !== Array) {
          graphic = this._createGraphic(arcgisJson);
          this._addGraphicToLayer(graphic);
       } else {
          // Limit size of data that can be drawn
          if (arcgisJson.length > this._maxDraw) {
              this._drawCountTotal = this._maxDraw;
              console.warn("GeoJsonLayer Warning: Large dataset detected. Only drawing the first " + this._maxDraw + " features!");
          } else {
              this._drawCountTotal = arcgisJson.length;
          }
          // Add graphics to the layer with symbols, project if needed
          for (i = 0; i < this._drawCountTotal; i++) {
              feature = arcgisJson[i];
              // Create graphic - magically sets the geometry type!
              graphic = this._createGraphic(feature);
              // Add to layer
              this._addGraphicToLayer(graphic);
          }              
       }

sorry for the delayed reply @GB11111 but its by design that this project expects a GeoJSON feature collection to be supplied.
