\arguments{
\item{where}{String An optional expression to filter features server side.
String values should be denoted using single quotes ie: where: "FIELDNAME = "field value""; More information about valid SQL syntax can be found at \url{http://resources.arcgis.com/en/help/main/10.2/index.html#/SQL_reference_for_query_expressions_used_in_ArcGIS/00s500000033000000/}.}

\item{minZoom}{Integer Minimum zoom level of the map that features will display.
example: minZoom:0}

\item{maxZoom}{Integer Maximum zoom level of the map that features will
example: maxZoom:19}

\item{cacheLayers}{Boolean Will remove layers from the internal cache when they are removed from the map.}

\item{fields}{Array An array of fieldnames to pull from the service.
Includes all fields by default. You should always specify the name of the unique id for the service. Usually either "FID" or "OBJECTID".}

\item{from}{Date When paired with to defines the time range of features to display.
Requires the Feature Layer to be time enabled.}

\item{to}{Date When paired with from defines the time range of features to display.
Requires the Feature Layer to be time enabled.}

\item{timeField}{false The name of the field to lookup the time of the feature.
Can be an object like {start:"startTime", end:"endTime"} or a string like "created".}

\item{timeFilterMode}{"server" (default) or "client" Determines where features are filtered by time.
By default features will be filtered by the server. If set to "client" all features are requested and filtered by the app before display.}

\item{simplifyFactor}{Integer How much to simplify polygons and polylines.
More means better performance, and less means more accurate representation.}

\item{precision}{Integer How many digits of precision to request from the server.
Wikipedia has a great reference of digit precision to meters at \url{http://en.wikipedia.org/wiki/Decimal_degrees}.}

\item{token}{String If you pass a token in your options it will be included in all requests to the service.}

\item{proxy}{URL of an \href{https://developers.arcgis.com/javascript/jshelp/ags_proxy.html}{ArcGIS API for JavaScript proxy} or \href{https://github.com/Esri/resource-proxy}{ArcGIS Resource Proxy} to use for proxying requests.}

\item{useCors}{Boolean If this service should use CORS when making GET requests.}

\item{renderer}{L.svg or L.canvas The vector renderer to use to draw the service.
Usually L.svg but setting to L.canvas contains performance benefits for large polygon layers.}
