What does @nodebb location does?

[darkpollo]

I found this:

location @nodebb {
        proxy_pass http://io_nodes;
    }

here https://docs.nodebb.org/configuring/scaling/

But not here:
https://docs.nodebb.org/configuring/proxies/nginx/

My site is working without that location and I am not sure why is needed.
Which one is correct and what is that for?

Thanks

It is used when you run nodebb on multiple ports.

NginX - NodeBB Documentation

Documentation portal for NodeBB Forum Software

(docs.nodebb.org)

That does not appear on the link you pasted.

It is a location not a proxy.

For what I can see in the forum, this is something old from tryfiles and older nginx config:
https://community.nodebb.org/topic/10228/introducing-the-build-system-in-v1-4-x/22

Can someone confirm this is the case and the code:

    location ~ ^/forum/assets/(.*) {
        root /path/to/nodebb/;
        try_files /build/public/$1 /public/$1 @nodebb;
    }

    location ~ ^/forum/plugins/(.*) {
        root /path/to/nodebb/build/public/;
        try_files /plugins/$1 @nodebb;
    }

Is no longer required?
My forum seems to be working fine with the docs nginx file.

Replying to myself, this is required when using additional locations for static files.
