hi @reyemtm - we would definitely like to keep moving forward on this plugin; just looking for contributors. You should submit your fix as PR and I will happily review.
BTW, Koop sets CORS wide-open internally, so I am not sure you need the { 'Access-Control-Allow-Origin': '*' }
, but I haven't looked into it.
Sounds good. There are a few other updates I have in mind. I have another issue which might be related to the core...response time is slow to get to the output plugin...not sure how to debug that one.

What provider are you using?
Local file geojson provider. You can check the request received log in the output plugin. I think I am right in that the data file is passed to memory by default?

Yes, that provider has data cached for 10 seconds (geojson.ttl = 10
). After 10 seconds, it will fire getData again and re-read the file.
Oh thanks that explains what I am experiencing. I will look at adjusting the cache timeout.

A couple more thoughts on this cache. Increasing the cache ttl fixed the behavior I was seeing. Any reason to keep this limit low? Is there a fear that keeping the file in cache will lead to high mem usage, or is it that the underlying file could change? Trying to figure out the reasoning so I can better justify my approach.

There's no particular reason the ttl
is to 10 seconds. I use this provider mainly for debugging and testing koop-core, FeatureServer, and Winnow, so I haven't really scrutinize performance details.
Ideally, the ttl
should be set by a provider-namespaced config value, so that it's not hardcoded in the getData
function. Feel free to submit a PR on that repo, or maybe I can squeeze in the change sometime soon.
Is this still in development? I am looking at using Koop to add layers into AGOL using the feature server output from static geojson files. This seems like the simplest method for accomplishing this outside of loading the data into AGOL. If so I will add more issues. If not disregard.
If geojsonVT(data).getTile(z, x, y) is null then the plugin crashes as it calls vtpbf using a null tile. A simple fix would be something like the following:
