Vue Router With Vue 3 Raises The Error Uncaught TypeError Object is Not a Function

If you are working with Vue 3 and Vue Router, you may come across the error message "Uncaught TypeError: Object is not a function." This error can be frustrating, but with a little understanding, you can resolve it quickly.

When this error occurs, it typically means that you are trying to use an object as a function in your code. In the context of Vue Router and Vue 3, this often happens when there is a mismatch in the way you are importing or initializing your router instance.

To resolve this error, the first step is to check your code for any instances where you might be incorrectly using an object as a function. Pay close attention to how you are importing and using Vue Router within your Vue 3 project.

One common cause of this error is importing Vue Router incorrectly. Make sure you are importing Vue Router using the correct syntax for Vue 3. In Vue 3, the way you import and create the router instance has changed slightly from previous versions.

Here is an example of how you should import and use Vue Router in a Vue 3 project:

Javascript

import { createRouter, createWebHashHistory } from 'vue-router';

const router = createRouter({
  history: createWebHashHistory(),
  routes: [
    // your routes here
  ],
});

By following this pattern, you ensure that you are importing and creating the router instance in the correct way for Vue 3.

Another common mistake that can lead to the "Uncaught TypeError: Object is not a function" error is initializing the Vue Router instance improperly. When setting up your router, make sure you are passing the correct configuration options and defining your routes correctly.

Additionally, verify that you are registering the router instance with your Vue app appropriately. In Vue 3, you should use the `app.use` method to register the router with your Vue instance:

Javascript

import { createApp } from 'vue';
import App from './App.vue';
import router from './router';

const app = createApp(App);
app.use(router);
app.mount('#app');

By following these steps and ensuring that you are importing, initializing, and registering your Vue Router instance correctly, you can prevent the "Uncaught TypeError: Object is not a function" error from occurring in your Vue 3 project.

In conclusion, while encountering errors in your code can be frustrating, understanding the root cause and following best practices can help you resolve them efficiently. By paying attention to how you import and use Vue Router in Vue 3, you can avoid common pitfalls and keep your project running smoothly.
