I was able to get it to build and run in docker successfully. Now, how do I get nos2x to work? The local site isn't prompting me for a key or extension like the production site does?

it should prompt you unless you are using private browser. it always prompts me when i run on localhost.
Just re-open or reload the browser. It should then offer to read from plugin.
the local site does not do that for me. 
let me know if you figure this out derek.
thinking about trying to run it locally as well.
can you try using http://localhost:8080/ instead? cantillion effect seemed to say this fixed it.
