All I find is nodebb-plugin-write-api which is not enough. It doesn't even have login API.I am not familiar with nodejs.And it is not necessary to handle the problems only existing on browser like CSRF.
Tried on chrome, this is the result
The forum continues to work as normal, but ad doesn't appear
is causing some server side or client side rendering / blocking?
More importantly, I'm not getting an issue like this. The only issue is that the sidebar is empty, for me
It's not possible to do exactly what you say, but it is possible to accomplish a similar thing by creating a NodeBB plugin which implements the API endpoint you want, instead of using the built-in API.
