Add map layers during runtime ESRI Javascript API

Question

I had a look through the ESRI js API (version:3/4) and examples on ESRI's page but I couldn't find something like an "add map layers from ", where the source is any reachable map service, WMS or ESRI Map service or something else.

If I want one I build it myself?

Answer 1

You can simply use some JavaScript to take in the URL and create the layer and add it to the map. Something like this:

var addLayer = (url) => {
 const layer = new FeatureLayer({
 url: url 
 });
 map.layers.add(layer);
 }

Of course you'll have to ask the user to specify the layer type, or detect it from the pattern. Here's an example for Feature Layer only to get you started.

• David I: Thanks for the example, the answer then is to build one myself rather than there being a "search for/browse and add layers from this predefined/runtimedefined source" widget ready. That's all I wanted to know : ) Also I shall make sure not to write "Friendly regards" anymore.
