so i've successfully started the server and whatnot, my question is: how does the client know to make requests to http://localhost:8080

what piece of config is the client looking at?

because that’s where the page was loaded from

ah, i see, so the untangled data fetch functions all just send EDN queries to whatever URL the page came from?

yep

you can actually specify a number of remotes. The “default” remote is the server you loaded from, at URI /api
