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

The error message “usenavigate() may be used only in the context of a <router> component.” occurs when the navigate function is used outside the scope of a router component.

For example, let’s say you have a Vue.js application that uses Vue Router for managing the application’s routes. In order to use the navigate function, it must be invoked within a router component, such as the root Vue instance, a component rendered by the router, or a child component of a router component.

Here’s an example of how the navigate function can be properly used within a router component:

import { createApp } from 'vue';
import { createRouter, createWebHistory } from 'vue-router';

// Import your components
import Home from './components/Home.vue';
import About from './components/About.vue';

// Create router instance
const router = createRouter({
  history: createWebHistory(),
  routes: [
    { path: '/', component: Home },
    { path: '/about', component: About }
  ]
});

// Create the Vue application instance
const app = createApp({
  // ... your app configuration
});

// Mount the router to the application instance
app.use(router);

// Example usage of the navigate function within a router component
app.component('SomeComponent', {
  methods: {
    goToAboutPage() {
      this.$router.push('/about');
    }
  },
  // ... component configuration
});
  

In the above example, the navigate function is used within the “goToAboutPage” method of the “SomeComponent” component. The “$router” object is accessible within the component because the router has been mounted to the application instance using the “app.use(router)” method.

By ensuring that the navigate function is used within the context of a router component, you can avoid the “usenavigate() may be used only in the context of a <router> component.” error message.
