What is the correct way to instantiate a new LMap and display it or add it to the MapContainer?
I have tried LMap map = new LMap(reg,"my-id"); but can't get this map to display.

Ultimately, I am trying to create a map where I can set the 'id'. Then via js, change properties of the LMap by retrieving the id etc...

What is the correct way to instantiate a new LMap and display it or add it to the MapContainer?

To quote from our usage section:

To get started it's recommended to have a look at the demo, notably the minimalistic example.

I have tried LMap map = new LMap(reg,"my-id"); but can't get this map to display.

Okay I need more info here otherwise I can't help.

The id inside the constructor is used for the component that will display the map. This is also documented in Leaflet.

Thanks for the response. Let me try again.
I want to set the 'zoomDelta' for the LMap. Unfortunately, your implementation in LMapOptions.setZoomDelta takes an Integer as a parameter - unlike Leaflet's zoomDelta property which accepts double values. I want granularity smaller than 1.
My workaround was to try and access the map object directly via js and set the 'zoomDelta' property that way. However, I can't get the LMap id.

Ok that's something completely different as was described in the issue.

Okay so that has a wrong data type, we should fix that.

You could run something like this:

map.invokeSelf(".options.zoomDelta = 0.2");

or extends from LMapOptions and override the datatype with e.g. a Double

Following up on this. Cool that you fixed it in the above commit, thanks. Is there a way to access the map element directly? The above line map.invokeSelf(".options.zoomDelta = 0.2"); does not work for me, in fact nothing with map.invokeSelf seems to. What am I missing? Thanks.

So I had a quick look into this:

The values are written to options as expected however leaflet is not updating the map automatically as the options seem to be only used during Map initialization.

This is a leaflet specific problem and not related to the component.
