What is the best way to render a feature layer using drawingInfo in Webmap JSON?

[ynunokawa]

I think that feature layers to include a feature collection with drawingInfo should be rendered using Esri Leaflet Renderers in the issue #32 .
The goal of this concept is that all feature layers use the same logic as Esri Leaflet Renderers to render.

There are prospected requirements to perform it.

• Esri Leaflet Renderers can refer original metadata with drawingInfo
• It renders FeatureCollection using renderer modules of Esri Leaflet Renderers (for the present)
• L.esri.FeatureLayer can refer a feature collection

[jgravois]

just to clarify, it sounds like you are proposing:

• that L.esri.featureLayer should accept either a GeoJSON feature collection or a url in its constructor?
• esri-leaflet-renderers is able to interpret drawingInfo passed in the object constructor and skip fetching information about symbology from the service itself entirely?

is that correct?

[ynunokawa]

Yes, that's right.

esri-leaflet-renderers is able to interpret drawingInfo passed in the object constructor and skip fetching information about symbology from the service itself entirely?

I have updated to rewrite drawingInfo from the service with original drawingInfo in esri-leaflet-renderers and created PR.

It use new drawingInfo option of L.esri.FeatureLayer as the below.

L.esri.featureLayer({
  url: 'http://...',
  drawingInfo: webmapJson.***.drawingInfo
});
