The Role of the $route Object in Vue Router

In Vue Router, the $route object plays a crucial role in managing the application's routing. It provides access to the current route and its properties, allowing developers to create dynamic and interactive applications.

What is the $route Object?

The $route object is an instance of the Route class, which is part of the Vue Router library. It is automatically injected into every component in the application, making it accessible via the this.$route syntax.

Properties of the $route Object

The $route object has several properties that provide information about the current route:

• path: The path of the current route.
• params: An object containing the route parameters.
• query: An object containing the query parameters.
• hash: The hash of the current route.
• fullPath: The full path of the current route, including the query and hash.
• matched: An array of route records that matched the current route.
• name: The name of the current route.
• meta: An object containing metadata about the current route.

Using the $route Object in Components

The $route object can be used in components to access the current route and its properties. For example:

<template>
  <div>
    <p>Current path: {{ $route.path }}</p>
    <p>Route parameters: {{ $route.params }}</p>
  </div>
</template>

<script>
export default {
  mounted() {
    console.log(this.$route);
  }
}
</script>

Watching the $route Object

The $route object can be watched using the watch property in the component's options. This allows developers to react to changes in the current route:

<script>
export default {
  watch: {
    $route(to, from) {
      console.log(to, from);
    }
  }
}
</script>

Conclusion

In conclusion, the $route object plays a crucial role in managing the application's routing in Vue Router. It provides access to the current route and its properties, allowing developers to create dynamic and interactive applications.
