Which theme for future NodeJS versions?
I would like to install NodeJS for a new fresh forum but before doing this, I have a few questions:
Where do I find a style which is modern and stable and compatible with future versions of NodejS?
Is NodeJS faster than forum solutions like Xenforo, IPB?
I do not find some the links to download the themes...
The vanilla, lavender, and persona themes are bundled with NodeBB. The default is Persona.
Additional themes are available for download via the plugins download page in NodeBB. An example of a third-party theme would be nodebb-theme-material by @pichalite
Yes, according to some measures, NodeBB is faster than Xenforo and IPB.
