There are a bunch of reasons why this is convoluted, mostly in building the URL to make the request:

1. You have to rely on an AJAX request, this example uses jQuery
2. To make a GetFeatureInfo request, you must provide a BBOX for a image, and the pixel coordinates for the part of the image that you want info from. A couple of squirrely lines of Leaflet code can give you that.
3. Output formats. The info_format parameter in the request. We don't know a priori which will be supported by a WMS that we might make a request to. See Geoserver's docs for what formats are available from Geoserver. That won't be the same from WMS to WMS, however.
4. WMS services return XML docs when there's a mistake in the request or in processing. This sends an HTTP 200, which jQuery doesn't think is an error.

Pre-commit git hook to require Golang formatting and linting

1. Add this file in a local repo at .githooks/pre-commit.
2. git config core.hooksPath .githooks sets up the hook

Satisfactory dedicated server on AWS ECS

A CloudFormation stack that you can run in your AWS account to host up a dedicated Satisfactory server.

Thanks to https://github.com/wolveix/satisfactory-server for the Docker image!

Runs on AWS ECS

The dedicated server application runs on ECS Fargate, so you get a more-or-less "serverless" setup. It uses Fargate Spot, which allows you to get the cheapest possible setup, though AWS may choose to stop and restart your server. FWIW I've never actually observed that happening.

function onEachFeature(feature, layer) {
	/* From the perspective of reading this function, it would be easier if you think about it in a linear fashion
		 What does this function do?
		 1) get a single feature
		 2) parse some specific properties out of the feature
		 3) use those properties to generate a string of HTML
		 4) build a popup from that HTML

		 Right now its a little hard to read because you're jumping around between those steps a bit
