Uselocation() may be used only in the context of a component.

Error: uselocation() may be used only in the context of a <router> component.

The error message “uselocation() may be used only in the context of a <router> component” occurs when you try to use the uselocation() function outside of a <router> component in a Vue.js application.

In Vue Router, the <router> component wraps your entire application and allows you to define routes and navigate between them. The uselocation() function is used to access the current route’s location information (i.e., URL, and navigation history). However, it can only be used within the scope of a <router> component or its child components.

To resolve this error, you need to ensure that you are using the uselocation() function within the context of a <router> component. Here’s an example of how to properly use uselocation() within a Vue Router setup:

<template>
  <router>
    <div>
      <p>Current path: {{ route.path }}</p>
      <p>Current query: {{ route.query }}</p>
      <p>Current hash: {{ route.hash }}</p>
    </div>
  </router>
</template>

<script>
import { useLocation } from 'vue-router';

export default {
  setup() {
    const route = useLocation();

    return { route };
  }
}
</script>

In this example, we import the useLocation() function from ‘vue-router’ and use it inside the setup() method to access the current route’s location information. We then bind the route object to the component’s template, which displays the current path, query, and hash values.

By wrapping the entire component with the <router> component, we ensure that the useLocation() function can be used without any errors.
