I want to create a route link with a common rule.

[yahao87]

I want to automatically put it in all a tags of the project when accessing the URL only when the following lang is included.
/about
/en/about
/ko/about
/ja/about

Since SvelteKit requires using anchor tags for links, do I have to insert the {lang} value into every anchor tag?
In non-Svelte libraries, I've seen examples where it's automatically created like:
previous /home => <router-link :to="{ name: 'about'}">about</router-link> => /about
previous /en/home => <router-link :to="{ name: 'about'}">about</router-link> => /en/about
previous /ko/home => <router-link :to="{ name: 'about'}">about</router-link> => /ko/about

But I'm not sure how to achieve this in SvelteKit right now. Can you help?
It seems like there are no hooks or anything.
For example, if I want to use a NavBar library, I have to do something like this:

<NavLi href={lang ? `/{lang}/home` : 'home'}>Home</NavLi>

Do I have no choice but to create a separate function to calculate the url value to put into the href?
