Dissolve javascript api 4.x

jaykapalczynski

Can you do a dissolve on a Graphics Layer in ArcGIS JavaScript API 4.x.

I see reference to this in 3.x but not 4.x

In JavaScript 4.14 I am selecting a specific number of features from a Feature Layer and writing them to a Graphics Layer.  I now want to dissolve them to a multi-part polygon so I can update a Feature Class Geometry.

Can I do this with the API or do I need to do this with a Python Published GP Tool

Jay,

  In ArcGIS Server Union is similar to  dissolve.

An example code follows:

<SPAN class="keyword token">var</SPAN> Geoms <SPAN class="operator token">=</SPAN> graphicsLayer1<SPAN class="punctuation token">.</SPAN>graphics<SPAN class="punctuation token">.</SPAN><SPAN class="token function">map</SPAN><SPAN class="punctuation token">(</SPAN><SPAN class="keyword token">function</SPAN><SPAN class="punctuation token">(</SPAN>gra<SPAN class="punctuation token">)</SPAN><SPAN class="punctuation token">{</SPAN>
  <SPAN class="keyword token">return</SPAN> gra<SPAN class="punctuation token">.</SPAN>geometry<SPAN class="punctuation token">;</SPAN>
<SPAN class="punctuation token">}</SPAN><SPAN class="punctuation token">)</SPAN><SPAN class="punctuation token">;</SPAN>‍‍‍
<SPAN class="keyword token">var</SPAN> union <SPAN class="operator token">=</SPAN> geometryEngine<SPAN class="punctuation token">.</SPAN><SPAN class="token function">union</SPAN><SPAN class="punctuation token">(</SPAN>Geoms<SPAN class="punctuation token">)</SPAN><SPAN class="punctuation token">;</SPAN>
graphicsLayer2<SPAN class="punctuation token">.</SPAN><SPAN class="token function">add</SPAN><SPAN class="punctuation token">(</SPAN>union<SPAN class="punctuation token">)</SPAN><SPAN class="punctuation token">;</SPAN><SPAN class="line-numbers-rows"><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN></SPAN>
