In Nuxt, we can use router-link as well as nuxt-link. What is the advantage of using nuxt-link over router-link?
<nuxt-link to="/about">About</nuxt-link>
instead of
<router-link to="/about">About</router-link>
According to Nuxt Docs, two important points:
This component (
<nuxt-link>) is used to provide navigations between page components and enhance performances with smart prefetching.
In fact,
<nuxt-link>extends<router-link>. That means it takes the same properties and can be used in the same manner.
After that we can read about smart prefetching:
Nuxt.js will automagically prefetch the code-splitted pages linked with when visible in the viewport by default. This hugely improves the end user performances.
Based on that I think you are simply looking at better performance with <nuxt-link>.
