Navigating the world of single-page applications (SPAs) often leads to encountering the infamous hashbang (!) in URLs. While once a common solution for client-side routing, the hashbang can create confusion for both users and search engines. If you’re working with Vue.js, a popular JavaScript framework for building SPAs, you might be wondering how to achieve cleaner, more SEO-friendly URLs without the hashbang. This comprehensive guide will walk you through the process, explaining the underlying concepts and providing practical steps to implement a more robust routing solution.
Understanding the Hashbang (!)
Before diving into solutions, let’s clarify the purpose of the hashbang. In the early days of SPAs, it served as a workaround for handling client-side routing without requiring full page reloads. The portion of the URL after the ! is never sent to the server, allowing JavaScript to intercept and interpret it to manage application navigation. However, this approach has several drawbacks, including hindering SEO as search engine crawlers traditionally struggled to interpret hashbang URLs.
Furthermore, hashbangs can be less user-friendly, appearing less intuitive and potentially causing issues with bookmarking and sharing specific application states.
Vue Router: The Key to Removing Hashbangs
Vue Router, the official routing library for Vue.js, provides the necessary tools to eliminate hashbangs and implement a more modern approach to routing. By utilizing the mode option in the router configuration, you can switch from the default hash mode to history mode, which leverages the HTML5 History API.
This shift enables clean URLs without the hashbang, resulting in a more user-friendly and SEO-friendly experience. The History API allows manipulation of the browser history without requiring server-side configuration, creating a seamless experience for the user as they navigate the application.
Implementing History Mode in Vue Router
Switching to history mode is straightforward. First, ensure you have Vue Router installed in your project. Then, within your router configuration file (typically router/index.js), modify the mode option as follows:
javascript import Vue from ‘vue’ import VueRouter from ‘vue-router’ import Home from ‘../views/Home.vue’ Vue.use(VueRouter) const router = new VueRouter({ mode: ‘history’, // Set mode to ‘history’ routes: [ { path: ‘/’, name: ‘Home’, component: Home }, // … other routes ] }) export default router This simple change effectively removes the hashbang from your URLs, creating cleaner paths like /about instead of //about. Remember to adjust any links within your application to reflect these new paths.
Server-Side Configuration for History Mode
While history mode utilizes the client-side History API, some server-side configuration is necessary to handle page refreshes and direct navigation to specific routes. Since the server only receives requests for the base URL, it needs instructions on how to serve the appropriate Vue.js application files. The most common approach involves configuring your server to return the index.html file for any request that doesn’t match a static asset. This ensures that Vue Router can handle the routing on the client-side, regardless of the entry point.
Specific server configurations vary depending on the server you’re using (e.g., Apache, Nginx, Express). Consult your server’s documentation for detailed instructions. For example, in a simple Express setup, you could implement this:
javascript const express = require(’express’); const app = express(); // Serve static files from the ‘dist’ directory app.use(express.static(‘dist’)); // Catch-all route for handling other requests (e.g., page refreshes) app.get(’’, (req, res) => { res.sendFile(__dirname + ‘/dist/index.html’); }); app.listen(3000, () => { console.log(‘Server listening on port 3000’); }); Best Practices and Considerations
- Testing: Thoroughly test your application after implementing history mode to ensure all routes function correctly.
- 404 Handling: Implement appropriate 404 handling on both the client and server sides.
- SEO Implications: While history mode enhances SEO, ensure your application is optimized for other SEO factors like meta descriptions and page titles.
By addressing these points, you can create a robust and SEO-friendly SPA with Vue.js.

Frequently Asked Questions
Q: Does switching to history mode require changing my existing components?
A: No, switching to history mode primarily involves updating the router configuration and server settings. Your components’ logic should remain largely unaffected.

Question & Answer :
How to remove hashbang #! from url?
I found option to disable hashbang in vue router documentation ( http://vuejs.github.io/vue-router/en/options.html ) but this option removes #! and just put #
Is there any way to have clean url?
Example:
NOT: #!/home
BUT: /home
Thanks!
In Vue 3, you’d want to use createWebHistory for the history option.
import { createRouter, createWebHistory } from 'vue-router' const router = createRouter({ history: createWebHistory(), // ... })
In Vue 2, you’d want to set mode to 'history'.
const router = new VueRouter({ mode: 'history', // ... })
Make sure your server is configured to handle these links, though. https://router.vuejs.org/guide/essentials/history-mode.html
