StreamServer

Hey guys,

We are currently integrating maps into our web application through the Leaflet API. We've gotten a few questions about supporting "live" layers (turns out they are StreamServers). This functionality seems to have more support through the ArcGIS JS SDK, but wondering if there are any recommendations on usage within Leaflet.

Searching around the web, I see some packages like esri-leaflet-stream which seem like wrappers around WebSockets. We could certainly do something similar, but I suppose I'm wondering if there is more official support, or examples.

Hi @AddisonShaw,

That's right, for everything with the exception of Esri cloud-hosted APIs that's usually the case.

I'm wondering if there is more official support, or examples.

I'm sorry, but as far as I know there is no official support for this and it is not planned to be 😔. But maybe we can get revitalize this plugin with community contributions.

A few years ago I had to do the opposite, convert a websocket to a Stream services to be consumed by the Maps SDK for JS, so we had to build a WebSockets wrapper too (but in this case for Node.js).

Related to this I recently I heard from @RichGwozdz about Koop that:

Output plugins can now use the pullStream method, so long as the linked providers include a getStream method. Docs forthcoming.

I hope this helps,
Raul
