Vue Router

Query parameters

https://something.com/user/456?locale=en

<router-link 
	:to="{ name: 'pathName', 
    	   params: { id: $route.params.id }, 
           query: { locale: 'en' } }">
</router-link>

Adding hash fragment

<router-link :to="{ name: pathName, hash: '#text' }">
	Jump to content
</router-link>

Scroll behavior

import { routes } from './routes.js'
const router = new VueRouter({
	routes,
    scrollBehavior(to, from, savedPosition) {
    	if (savedPosition) {
        	return savedPosition;
        }
        if (to.hash) {
        	return { selector: to.hash };
        }
        return { x: 0, y: 0 };
    }
});

Here, routes are all our routes kept in a separate file. The scrollBehavior()function is what manages the scrolling of our routes. It has 3 parameters:

1. to — This represents the new route we will be visiting
2. from — This is the previous route we came from. So if we click on a <router-link> on Home page to visit the About page, then to would be our About page and from is the Home page.
3. savedPosition — This is the important parameter. It represents the previous position before scrolling. It will become clear after I explain what the above function does.
