NavigationIn this post, we are going to learn how to use several features of the Angular Router in order to build a navigation system with multiple navigation levels, similar to what you would find in an online learning platform or an online store like Amazon but simpler. We will do this step by step, the goal here is to learn how to configure the Angular Router by example and learn how to implement some of the very common routing scenarios that you will likely find during your everyday development. We want to start by implementing the top menu, which will always be visible no matter where we navigate inside the application. For that we are going to add the top menu at the level of the root component of the application:. If the menu is too big then a good alternative is to put it in a separate top-menu. Notice the routerLink directives, linking to homeabout and courses. Also notice the router-outlet tag: this means the main content of the page below the top menu will be placed there. Also notice that there is no side navigation bar at this stage. The side navigation should only be visible if we click on Courses. Let's now write the router configuration for the top menu. As we can see, the homeabout and courses Url paths currently map to only one component. This is a good start, we have defined the home page, handled invalid URLs and added a couple of common navigation items. As we can see, the main content of the page everything below the top menu was applied in place of the router outlet. But this Courses page will also have other internal routing scenarios as we will see further. In order to create the navigation side menu, we would like the CoursesComponent to contain a couple of router outlets itself:. To implement this scenario we need to first start by going over Child Routes. We can learn more about Child Routes in this previous postor you might want to check this video:. Let's have a look at the CoursesComponent template, to see how we have implemented it:. Notice that there are a couple of router-outlet elements inside the courses component, which is itself being injected in place of a router outlet! This is sometimes referred to as the "nested" route scenario. We will go over the side menu outlet in a moment, but right now we want to configure the router to include the course category cards component in place of the unnamed router outlet. In order to display the courses component and the course categories card inside it, we need the following router configuration:. But how do we display the side menu? For that, we are going to need what is sometimes referred to an auxiliary route. Auxiliary route is a common term to describe this scenario where we have multiple portions of the screen whose content is dependent upon the value of the url. In terms of router configuration, this corresponds to a route with a non-default outlet name.

We'll see how to initialize an Angular 9 project and integrate it with Bootstrap 4. Next, we'll use the various Bootstrap 4 CSS utilities to create a responsive layout with navbars, tables, forms, buttons, cards and jumbotrons. Bootstrap is a free and open-source CSS framework for creating responsive layouts, it's mobile-first and contains ready CSS utilities for typography, forms, buttons, and navigation, etc. There are various ways of integrating Bootstrap 4 with your Angular 9 application. Let's see a possible solution by example. In your terminal, run the following command:. After initializing your Angular 9 project, let's proceed to install Bootstrap 4 and integrate it with Angular. Next, go the angular. After installing and integrating Bootstrap 4 with your Angular 9 project, let's create some components to test various Bootstrap styles. A Bootstrap Jumbotron is a lightweight, flexible component that can optionally extend the entire viewport to showcase key marketing messages on your site. We simply defined two variables employees and selectedEmployee for holding the set of employees and the selected employee. And a selectEmployee method which assigns the selected employee to the selectedEmployee variable. A Bootstrap 4 Card is a flexible and extensible content container. It includes options for headers and footers, a wide variety of content, contextual background colors, and powerful display options. Similar functionality to those components is available as modifier classes for cards. We use the built-in. We make use of the. Head over to your command-line interface, and run the following command from the folder of your project:. As a recap, we have seen how to initialize an Angular 9 project and integrate it with Bootstrap 4. Next, we used various Bootstrap CSS utilities to create a responsive layout with tables, forms, buttons, cards and jumbotrons. In this tutorial, we'll learn how to integrate and use bootstrap 4 with Angular 9. This tutorial works with all recent versions of Angular i. Would you like to add Angular routing?

The Angular 8 Router uses to navigate between views or pages that trigger by the user actions. The navigation or view changes happen when the user clicks on the link, click on the button, or enter the URL from the browser address bar. Every view change can bring the params of data from the previous view to the next view. So, make sure all of those items are installed in your machine and ready to run. We assume you are successfully installing Node. That Node. Next, we have to install Angular CLI by type this command. Next, to sanitize the newly created Angular 8 project go to that project folder then run the Angular application. If you open the project using your IDE or text editor, there is a starting component app. This component is the default view that trigger from the index. The simple Angular 8 Routing will contain a few pages or views that have the same level each other. From that diagram, we need to create the new components by type this command to generate it using Angular Schematics. Now, we have a home, about, privacy, and terms folders inside the app folder. All of those Components routes wrapped inside app. Dynamic views changes inside the router-outlet tag. So, we can use the rest of app. Next, install the ng-bootstrap module using this command. Add this stylesheet reference to the Bootstrap stylesheet in the index. We add the toggleNavbar function to make this Boostrap responsive and the menu working on the thinner width. The navigation works by click on the navigation item and it's done by the Angular [routerLink]. To marked active view in the Boostrap navigation bar, the Angular routerLinkActivate just use inline with the [routerLink]. And here's how it works. From the previous example of the simple Angular Routing you just can navigate to the routing that defines in the app-routing. So, it will look like this. That wildcard route required a PageNotFoundComponent. For that, generate a new component by this command. Let's try by add two new models using these commands. That commands will generate articles and products modules with their own module and routing module files. But, we have to set order of AppRoutingModule to be the last after above-added modules. Next, we will add the list and details views to each module. That commands will automatically be added or registered that components to each module file. So, the structure of the whole Angular application will be like this. Now, we will add a route for each component in each module. The details component route will contain a parameter. To send parameters to that route, we can use the [routerLink] to send data to that params.
