What Is Route Matching Priority in Vue.js

Route Matching Priority

In Vue.js, route matching priority refers to the order in which the routes are evaluated and matched when navigating within a Vue.js application using the Vue Router. Vue Router allows you to define routes for your application, and when a user navigates to a specific URL, the router needs to determine which route configuration corresponds to that URL.

Route matching priority is important because it determines which route will be used when there are multiple routes that potentially match a given URL. The order in which you define your routes can impact which route gets matched first.

Routes in Vue Router are typically defined using the routes configuration array. When a user navigates to a certain URL, Vue Router iterates through the routes array and tries to match the URL with the path specified in each route definition. The first match it finds is used, and subsequent routes are ignored.

Here's an example of route matching priority.

const routes = [
  { path: '/home', component: Home },
  { path: '/about', component: About },
  { path: '/users/:id', component: User },
  { path: '*', component: NotFound },

const router = new VueRouter({

In this example, if a user navigates to "/home," the first route with the path "/home" will be matched, and the Home component will be rendered. If the order of the routes were different, the matching behavior could change.

It's important to define more specific routes before less specific ones to ensure that the router prioritizes the more specific routes. For example, the route with the path "/users/:id" is more specific than the generic catch-all route with the path "*". If you define the catch-all route first, it will match any URL, and the more specific routes won't have a chance to match.


When working with Vue Router, consider the order in which you define your routes to ensure that the route matching priority aligns with your desired behavior.
