Navigating Between Routes in Vue Router

In Vue Router, the $router object is used to navigate between routes. This object is automatically injected into every component by Vue Router, allowing you to access its methods and properties to control the navigation flow of your application.

Accessing the $router Object

The $router object is available in every component as this.$router. You can access it in your component's methods, computed properties, or lifecycle hooks.

// Accessing the $router object in a Vue component
export default {
  methods: {
    navigateToRoute() {
      this.$router.push({ name: 'home' });
    }
  }
}

Navigating to a Route

To navigate to a route, you can use the push() or replace() methods of the $router object. The push() method adds a new entry to the browser's history stack, while the replace() method replaces the current entry.

// Navigating to a route using the push() method
this.$router.push({ name: 'home' });

// Navigating to a route using the replace() method
this.$router.replace({ name: 'home' });

Passing Parameters to a Route

You can pass parameters to a route by including them in the object passed to the push() or replace() methods.

// Passing parameters to a route
this.$router.push({ name: 'user', params: { id: 1 } });

Navigating to a Route with Query Parameters

You can navigate to a route with query parameters by including them in the object passed to the push() or replace() methods.

// Navigating to a route with query parameters
this.$router.push({ name: 'search', query: { keyword: 'vue' } });

Programmatic Navigation

In addition to using the push() and replace() methods, you can also use the go() method to navigate programmatically. The go() method takes a single integer argument, which represents the number of steps to move forward or backward in the browser's history stack.

// Navigating forward one step
this.$router.go(1);

// Navigating backward one step
this.$router.go(-1);

Dynamic Route Matching

In some cases, you may need to navigate to a route dynamically based on certain conditions. You can use the $router's match() method to achieve this.

// Dynamic route matching
const route = this.$router.match({ name: 'user', params: { id: 1 } });
if (route) {
  this.$router.push(route);
}

Conclusion

In this article, we explored how to use the $router object to navigate between routes in Vue Router. We covered various methods, including push(), replace(), go(), and match(), and demonstrated how to pass parameters and query parameters to routes. By mastering these techniques, you can create complex navigation flows in your Vue.js applications.
