I am currently trying to make a website that has multiple pages but all of them will have the exact same navbar. The only solutions I could find are some client-side solutions using the
<template> tag, but I would like to do it server side. Is there any way to do this?
I think you are misunderstanding the template tag. It’s not for server-side rendering.
Your question doesn’t really specify what stack you are using besides NodeJS.
Maybe Pug might be something that would interest you.
