How To Reload Current Route In Ember Js

Ember.js is a popular framework used by many developers for creating web applications. One common requirement in web development is the ability to reload the current route dynamically, without refreshing the entire page. In this article, we will walk you through how to accomplish this task in Ember.js.

Before we dive into the code, it's essential to understand the structure of Ember routes. Routes in Ember.js are responsible for loading data and setting up the controller for a specific route. When you navigate within an Ember application, you move between different routes based on the URL.

To reload the current route in Ember.js, we can leverage the Ember service called `router`. The `router` service provides us with methods to interact with the router from within our components or controllers. One of the methods that the router service exposes is `transitionTo`, which allows us to transition to a different route.

To reload the current route, we can simply transition to the same route again. This triggers Ember to re-render the current route, effectively refreshing the content displayed on the page without a full page reload. Let's see how we can achieve this in code:

import { inject as service } from '@ember/service';
import Component from '@ember/component';

export default Component.extend({
  router: service(),

  actions: {
    reloadRoute() {
      this.router.transitionTo(this.router.currentRouteName);
    }
  }
});

In the code snippet above, we create a component that injects the `router` service provided by Ember. Inside the `reloadRoute` action, we call `transitionTo` with `this.router.currentRouteName` as the argument. This instructs Ember to transition to the current route, effectively reloading it.

You can then trigger this `reloadRoute` action from your template or any other component to reload the current route whenever needed. This method gives you a simple and efficient way to refresh the content of your application without disrupting the user experience.

It's important to note that reloading the route in this manner will not re-fetch any data unless explicitly implemented in your route or controller. If you need to fetch fresh data when reloading the route, you can add the necessary logic in the route's `model` hook or controller.

In conclusion, reloading the current route in Ember.js is a straightforward process that can enhance the user experience of your web application. By leveraging the `router` service and transitioning to the current route, you can refresh the content on the page dynamically. Remember to consider any data-fetching requirements when implementing route reloading in your Ember application to ensure your users always see the most up-to-date information.
