How to handle a 404 Not Found page with Vue Router?
Jul 26, 2025 am 01:28 AM
To handle 404 pages in Vue Router, define a catch-all route using /:pathMatch(.*)* as the last route in the route array to capture any unmatched paths. 2. Create a dedicated NotFound component with a user-friendly message and a link back home. 3. Import and register the NotFound component in the router configuration. 4. Optionally, access the requested URL via this.$route.params.pathMatch in the component for logging or suggestions. 5. Follow best practices by ensuring the 404 route is last, capturing full nested paths, and maintaining design consistency with clear navigation options, which ensures proper user experience and SEO support.
When using Vue Router, handling a 404 Not Found page properly is important for user experience and SEO. Here's how to set it up correctly.
Define a catch-all route for 404 pages
The key is to add a wildcard route at the end of your route list. Vue Router uses the first match, so the 404 route should be the last one.
const routes = [
{ path: '/', component: Home },
{ path: '/about', component: About },
{ path: '/user/:id', component: User },
// Always keep this as the last route
{ path: '/:pathMatch(.*)*', component: NotFound }
]Here, :pathMatch(.*)* is a greedy param that captures any unmatched path. The (.*) part matches any character, and the * means zero or more segments.
Create a dedicated NotFound component
Create a simple component to display when a page isn't found:
<!-- components/NotFound.vue -->
<template>
<div class="not-found">
<h1>404 - Page Not Found</h1>
<p>The page you're looking for doesn't exist.</p>
<router-link to="/">Go Home</router-link>
</div>
</template>
<style scoped>
.not-found {
text-align: center;
margin-top: 50px;
}
</style>Then make sure to import and use it in your router:
import { createRouter } from 'vue-router'
import NotFound from './components/NotFound.vue'
const routes = [
// ... your routes
{ path: '/:pathMatch(.*)*', name: 'NotFound', component: NotFound }
]
const router = createRouter({ /* config */ })Optional: Access the requested URL
You can access the unmatched path in the component via route params:
// In your NotFound component
export default {
mounted() {
console.log(this.$route.params.pathMatch) // e.g., 'nonexistent-page'
}
}This lets you log 404s or even suggest corrections.
Best practices
- Always place the 404 route last in the route array.
- Use
pathMatchto capture full nested paths like/foo/bar/baz. - Consider redirecting programmatically in rare cases (e.g. known legacy URLs).
- Keep the design consistent with your site and offer a clear way back (like a "Go Home" link).
Basically, with Vue Router, 404 handling is just a smart use of dynamic segments — no special error handling needed. Just make sure the catch-all route is registered last.

What is headless UI in Vue?
Jul 08, 2025 am 01:38 AM
HeadlessUIinVue refers to a library of UI components that provide no preset styles and only contains core logic and behavior. Its features include: 1. No style restrictions, developers can customize the design; 2. Focus on barrier-free and interactive logic, such as keyboard navigation, state management, etc.; 3. Support Vue framework integration, exposing the control interface through combinable functions or components. Reasons for use include: maintaining design consistency, built-in accessibility, strong component reusability, and lightweight library size. In practical applications, developers need to write HTML and CSS themselves. For example, when building a drop-down menu, the library handles state and interaction, while developers decide on visual presentation. Mainstream libraries include HeadlessUI and RadixVue for TailwindLabs, suitable for
How to watch nested properties in Vue 3?
Jul 07, 2025 am 12:51 AM
In Vue3, there are three ways to monitor nested properties using the watch function: 1. Use the getter function to accurately monitor specific nested paths, such as watch(()=>someObject.nested.property,callback); 2. Add the {deep:true} option to deeply monitor changes within the entire object, which is suitable for situations where the structure is complex and does not care about which property changes; 3. Return an array in the getter to listen to multiple nested values ??at the same time, which can be used in combination with deep:true; in addition, if ref is used, the nested properties in its .value need to be tracked through getter.
Key differences between Vue 2 and Vue 3?
Jul 09, 2025 am 01:29 AM
Vue3 has improved in many key aspects compared to Vue2. 1.Composition API provides a more flexible logical organization method, allowing centralized management of related logic, while still supporting Vue2's Options API; 2. Better performance and smaller package size, the core library is reduced by about 30%, the rendering speed is faster and supports better tree shake optimization; 3. The responsive system uses ES6Proxy to solve the problem of unable to automatically track attribute addition and deletion in Vue2, making the responsive mechanism more natural and consistent; 4. Built-in better support for TypeScript, support multiple node fragments and custom renderer API, improving flexibility and future adaptability. Overall, Vue3 is a smooth upgrade to Vue2,

Benefits of using ?
Jul 08, 2025 am 12:20 AM
? in regular expressions are used to convert greedy matches to non-greedy, achieving more accurate matches. 1. It makes the content as little as possible to match as little as possible to avoid mismatch across tags or fields; 2. It is often used in scenarios such as HTML parsing, log analysis, URL extraction, etc. that require precise control of the scope; 3. When using it, it is necessary to note that not all quantifiers are applicable. Some tools need to manually enable non-greedy mode, and complex structures need to be combined with grouping and assertions to ensure accuracy. Mastering this technique can significantly improve text processing efficiency.
