Building an Effective Navigation Menu in Angular: A Step-by-Step Guide

Creating a Navbar in Angular

In today’s world, web applications are everywhere. As users, we interact with them on a daily basis, and as developers, we work hard to create them.

One essential element of every web application is the navbar. It is the navigation bar that provides users with a way to move around the application.

In this article, we will discuss the importance of the navbar in web applications and how to create and generate navbar components in Angular.

Importance of Navbar in Web Applications

A navbar is one of the essential elements of a web application. It provides a consistent way for users to navigate between different pages or sections of an application.

It enables a user to access the desired content of an application with ease and enhances the user experience. So, a navbar is not just a menu bar; it is an integral part of the navigation UI.

Navigation Methods and Angular’s Router Navigate() Method

There are various methods to navigate between pages in a web application such as clicking a hyperlink, using the browser’s back and forward buttons, typing the URL in the address bar, etc. When it comes to Angular, this framework provides its own Router Service to navigate between pages.

Angular Router helps to navigate from one view to another view in the application. Angular Router has various APIs that are used to navigate from a component to another component for a specific URL.

The Router Service enables the creation of clickable links that navigate to other views and updates the browser URL and history. To use the Angular Router Service, we need to create component routes and register them in the app-routing.module.ts file.

We also need to import the Router service and use the navigate() method to navigate between different pages of the application. The navigate() method takes a URL parameter and navigates to the specified URL.

Generating Navbar Components in Angular

Creating a Navbar is not a difficult task in Angular. We can reuse the logic of the Navbar across different pages in our application.

When we create a Navbar, we must define the Navbar component, which contains the navbar HTML and CSS code. We will use that component in the pages where the navbar is required.

Creating Index, About Us, and Products Components

Now, let’s create a Navbar component that includes the Index, About Us, and Products components. First, we need to create a new component through the Angular CLI.

We do this by running the following command in the terminal:

> ng g c Navbar

Once we run this command, Angular CLI generates the Navbar component with its HTML, CSS, and Typescript files, and it adds the component to the app.module.ts file as well. Next, we create three components- index, about-us, and products- that will be used as links in the Navbar.

We create these files by running the following commands in the terminal:

> ng g c Index

> ng g c AboutUs

> ng g c Products

After running these commands, Angular CLI generates the component files for Index, AboutUs, and Products.

Now that we have created all the components, let’s include them in the Navbar component’s HTML code.

We create a material design navbar and include links to index, About Us, and Products pages.

Conclusion

In conclusion, the Navbar is a vital aspect of web applications as it allows users to navigate between different pages with ease. In Angular, we can use the Router Service to navigate between pages and create navbar components with ease.

By incorporating subheadings, bullet points, and numbered lists, we effectively discussed how to generate navbar components in Angular. It is essential to remember the importance of the navbar in web applications and the advantages it brings to a user’s experience.

Creating Views for the Components

After generating the navbar components in Angular, we can now proceed to create views for these components. A view is the visible part of the component that is displayed to the user.

In Angular, views are created using HTML templates.

To create views for the components, we need to add code to the HTML file of each component.

We can use Angular CLI to generate the HTML files for each component. We can do this by running the following command for each component in the terminal:

> ng g c aboutUs

> ng g c index

> ng g c products

Angular CLI will generate the HTML, CSS, and Typescript files for each component.

We can now open the HTML file for each component and add code to create views for these components as follows:

Adding code to aboutUs.component.html

In the aboutUs.component.html file, we can use the HTML tags to create a view for the about us page. We can add text, images, and other elements as required.

For example, we can add the following code to display the name of the company and a brief description:

Our Company

Welcome, we are a company that provides top quality products to meet your needs. We specialize in producing premium products that are sustainable and eco-friendly.

We can also add links to other pages of our application, such as the index and products pages, using the Angular Router. We will create links in our navbar to navigate to these pages.

Adding code to index.component.html

In the index.component.html file, we can use the HTML tags to create a view for the index page. We can add text, images, and other elements as required.

For example, we can add the following code to display various product categories and their images:

Our Products

We can also add links to other pages of our application, such as the about us and products pages, using the Angular Router. Adding code to products.component.html

In the products.component.html file, we can use the HTML tags to create a view for the products page.

We can add text, images, and other elements as required. For example, we can add the following code to display a list of products and their descriptions:

List of Our Products

  • Apples- Apples are a great source of fiber and antioxidants.

  • Oranges- Oranges are a rich source of vitamin C.
  • Bananas- Bananas are a good source of potassium.
  • Mangos- Mangoes are a good source of vitamin A and antioxidants.

We can also add links to other pages of our application, such as the about us and index pages, using the Angular Router.

Defining Component Routes

Once we have created views for the components, we can now define component routes in the app-routing.module.ts file. The app-routing.module.ts file is the main file where we define the routes of the application.

To define the routes, we first need to import the necessary modules from Angular. We need to import NgModule, Routes, and RouterModule.

We also need to import the components that we want to route. We can do this by adding the following code at the top of the app-routing.module.ts file:

import { NgModule } from ‘@angular/core’;

import { Routes, RouterModule } from ‘@angular/router’;

import { AboutUsComponent } from ‘./about-us/about-us.component’;

import { IndexComponent } from ‘./index/index.component’;

import { ProductsComponent } from ‘./products/products.component’;

We can now define the routes using path and component.

We need to add the following code in the routes constant in the app-routing.module.ts file:

const routes: Routes = [

{ path: ”, redirectTo: ‘/index’, pathMatch: ‘full’ },

{ path: ‘about-us’, component: AboutUsComponent },

{ path: ‘index’, component: IndexComponent },

{ path: ‘products’, component: ProductsComponent }

];

In this code, we have defined the routes for the application. When the application loads, it will redirect to the index page.

We can navigate to the about us, index, or products pages using the routes defined in the constant.

Conclusion

In conclusion, creating views for the components and defining component routes are essential steps in creating a web application. Using Angular, we can generate components, create views using HTML templates and code, and define component routes using the Angular Router.

Incorporating proper HTML elements along with the background API implementation, as defined in the above paragraphs, we can make more interactive and successful web applications.

Creating a Navigation Menu

A Navigation menu is an essential part of a web application as it guides users to different sections or pages of the application. In Angular, we can easily create a navigation menu using app.component.html file and then display components data using router-outlet.

Using app.component.html to create a Navigation Menu with Links

In the app.component.html file, we can create a navigation menu using HTML tags. We can add links to different pages of our application using the Angular Router.

We can create a navigation menu with links by adding the following code to the app.component.html file:

In this code, we have created a navigation menu using the bootstrap framework. We have added links to different pages of our application using the Angular Router.

We set the routerLink attribute of each anchor tag to the corresponding component’s route path. Displaying Component’s Data Using Router-Outlet

After creating a navigation menu with links, we need to display components’ data using the router-outlet tag.

The router-outlet is a directive in Angular that displays the component that corresponds to the active route. To display components’ data using router-outlet, we need to add the following code to the app.component.html file:

This code tells Angular to display the component that corresponds to the active route.

We place this code within the main body of the HTML file so that it displays the content of the components.

Creating Functions to Navigate Between Components

We can create functions to navigate between components using the router.navigate() method and import the Router into the app.component.ts file. Importing Router into app.component.ts

To import the Router into the app.component.ts file, we need to add the following code at the top of the file:

import { Router } from ‘@angular/router’;

We then need to add the Router service to the constructor of the app.component.ts file as follows:

constructor(private router: Router) { }

This code injects the Router service into the app component’s constructor, making it available to the component.

Creating Functions goToIndex(), goToAboutUs(), and goToProducts() to Navigate Between Components Using router.navigate()

Now, let’s create functions that will navigate between components using the router.navigate() method. We can create functions in the app.component.ts file and call them with the click event of anchor tags in the app.component.html file.

We will add functions to the app.component.ts file as follows:

goToIndex() {

this.router.navigate([‘/index’]);

}

goToAboutUs() {

this.router.navigate([‘/about-us’]);

}

goToProducts() {

this.router.navigate([‘/products’]);

}

In these functions, we use the router.navigate() method to navigate to the corresponding component’s route path. We pass the route path as an array of strings to the navigate() method.

We can call these functions using the click event of anchor tags in the app.component.html file as follows:

Index

About Us

Products

In this code, we have added the click event to each anchor tag. When the user clicks on the anchor tag, it will call the corresponding function.

Conclusion

In conclusion, creating a Navigation menu and Navigating between components is easy with Angular. We can create a navigation menu with links using app.component.html file and display components data using router-outlet.

We can also create functions that will navigate between components using the Router.navigate() method and import the Router into the app.component.ts file. These methods are crucial in making navigation more effective, making our web applications more interactive and more comfortable for users to navigate.

In summary, creating and generating navbar components, defining component routes, creating views for components, and creating a navigation menu are essential steps in building a successful and interactive web application using Angular. These features enable efficient navigation and enhance the user experience, making it easier for users to access the content they want.

By utilizing the techniques mentioned in this article, developers can create interactive and engaging web applications that meet user needs. It is essential to keep the navbar and navigation menu easy to use while providing all the necessary information.

Thus, it is essential to create a navigation menu that is easy to understand and use and to ensure that your code is structured in a way that is easy to read and understand.
