NodeBB Plugin and Theme authors

I'm guessing your issue is caused by the URL property in config.json not exactly matching the URL at which you're accessing the site.
@hotteshen glad you solved it! Do you mind sharing your solution for the benefit of others having a similar issue in the future?
There's another option which is to listen on action:ajaxify.start and set payload.url = null if it matches /app
@butteredroll yes serving static assets is a good point. It is much more efficient with nginx.
You might need to set those mime types on your reverse proxy
I think the only option right now, is to embed that HTML in the custom pages html widget.
So essentially what setup does is run you through creating config.json, generates package.json, and sets up the database.
So after running setup once, you can just copy those around between everything else, adjusting the address of the database and whatnot, and running npm install to install the deps, or just copying the node_modules directory for that.
Also you'll probably want to set a custom uploads folder.
Nginx site name should be whatever your load balancer is passing through, which should usually be your site address. If you're using a load balancer already, though, you probably don't need nginx in between. the nodebb url should be the URL that you see in your browser when you visit the forum. (for instance, it's set to https://community.nodebb.org here)
EADDRINUSE means nodebb is already running
@youhosi Thanks for the reminder!
Does anyone have any fake data I can use for testing?
...or is there a generator for this in the form of a plugin?
I've decided to dedicate my time to create a new theme.
