Navigating and refreshing routes within Angular are critical concepts in modern web development. Angular has become a cornerstone in the world of front-end development, due to its extensive functionality, versatity and robustness. Yet, it’s also a complex tool with numerous services, components, and modules which are particularly important for developers to understand. Today, we’re focusing on how to navigate to route and refresh in Angular 6.
import { Component, OnInit } from '@angular/core';
import { Router } from '@angular/router';
@Component({
selector: 'app-example',
templateUrl: './example.component.html',
styleUrls: ['./example.component.css']
})
export class ExampleComponent implements OnInit {
constructor(private router: Router) { }
ngOnInit() {
}
refresh(): void {
this.router.navigate(['/example-component']).then(() => { window.location.reload(); });
}
}

In Angular, we navigate between different routes by using the Router Service’s ‘navigate’ method. This method accepts an array of routes as parameters, and it navigates to the first one that matches the provided paths. In the example code above, ‘/example-component’ is the route we’re directing the user to. If successful, the nested promise uses the window object’s reload method to refresh the page.
This can be done on the click of a button, for instance, which invokes the method by binding it to a ‘click’ event within an HTML template. This event binding is part of Angular’s declarative programming paradigm, which simplifies the way you manage user interactions.
Refreshing a Route in Angular 6
Refreshing a route in Angular is not natively supported, as Angular was designed for single-page applications where full page refreshes contradict the very concept. However, full page refreshes can sometimes be useful, especially when you want to reset all your application data and view, or when you want to reload just the micro frontend.
To refresh a route, we use the window.location.reload() method, which refreshes the current page. Note this isn’t advised in most cases, since it circumvents Angular’s routings.
JavaScript and Angular 6
JavaScript software libraries such as AngularJS have revolutionized the world of web development, simplifying complex code into solutions that are efficient and easy to implement.
In Angular 6, developers can achieve navigation and refreshing of routes, a vital feature for any web application, in a simplified manner using Angular’s powerful Router Service and JavaScript’s window object. This effectively bypasses the tiring process of manually re-rendering or refreshing your pages. While Angular may not directly support this, the simplicity of using these inbuilt methods in JavaScript makes these challenges much more manageable, thereby improving your overall web development process.
In a world where efficient and fast solutions are paramount, understanding these two concepts could become a game changer. By mastering them, developers can build applications that are not just functional and robust, but also scalable. The importance of JavaScript and Angular 6 in modern web development cannot be overstated.
