How to Fix Route Not Found Error in Vue Router

The route not found error in Vue usually happens when the requested path is not defined in your vue-router routes. To fix it, ensure your routes array includes the correct paths and that your router is properly registered in your Vue app.

Why This Happens

This error occurs because Vue Router cannot find a matching route for the URL you are trying to visit. This often happens if the route path is missing, misspelled, or the router is not properly connected to your Vue app.

javascript

import { createRouter, createWebHistory } from 'vue-router'
import Home from './components/Home.vue'

const routes = [
  { path: '/home', component: Home }
]

const router = createRouter({
  history: createWebHistory(),
  routes
})

export default router

// In main.js
import { createApp } from 'vue'
import App from './App.vue'
import router from './router'

const app = createApp(App)
// router not used here
app.mount('#app')

Output

Error: route not found when navigating to '/' or other paths not defined

The Fix

Make sure your routes array includes the correct paths you want to use, including the root path '/' if needed. Also, register the router with your Vue app using app.use(router) so Vue knows about your routes.

javascript

import { createRouter, createWebHistory } from 'vue-router'
import Home from './components/Home.vue'

const routes = [
  { path: '/', component: Home }
]

const router = createRouter({
  history: createWebHistory(),
  routes
})

export default router

// In main.js
import { createApp } from 'vue'
import App from './App.vue'
import router from './router'

const app = createApp(App)
app.use(router)  // Register router here
app.mount('#app')

Output

Navigating to '/' correctly renders the Home component without errors

Prevention

Always define all routes you plan to use in your routes array, including a fallback or 404 route if needed. Register the router with app.use(router) before mounting the app. Use consistent path naming and test navigation early. Consider enabling strict linting rules for router configuration to catch missing routes.

Related Errors

Other common Vue Router errors include:

• NavigationDuplicated: Happens when trying to navigate to the current route again. Fix by checking current route before navigation.
• Failed to resolve async component: Occurs if a component import fails. Fix by verifying component paths.
• Missing router-view: If your app has routes but no <router-view>, nothing renders. Add <router-view> in your main component.

Key Takeaways

Always define all needed routes in your Vue Router configuration.

Register the router with your Vue app using app.use(router) before mounting.

Include a route for the root path '/' if your app uses it.

Test navigation paths early to catch missing or misspelled routes.

Add a fallback 404 route to handle unknown paths gracefully.
