Before You Start

Before delving into the intricacies of child routes, it’s essential to ensure that you have the necessary tools and prerequisites in place to seamlessly integrate child routes into your Angular application. Here are the key requirements to get started:

Prerequisites

• An integrated development environment (IDE) such as VS Code;
• Node Package Manager version 6.7 or above;
• The latest version of Angular (version 12): ng version.

Ensure that you are using Angular version 12 and update to this version if you are not already. Additionally, having a working knowledge of the Angular Router at a beginner level would be beneficial. If needed, you can review our previous article on Angular routing to refresh your understanding.

What Are Nesting Routes?

Understanding the concept of nesting routes is crucial for comprehending the power and flexibility it brings to Angular applications. Angular, being a component-based framework, organizes applications into components, forming a hierarchical tree structure. This means that sub-components stem from other components, creating a clear and organized architecture within the application.

For instance, in an Angular app, various components are typically found inside the main app component. Similarly, the Angular Router enables the creation of routes that are nested inside already-defined routes, allowing for a structured and organized navigation flow within the application.

Benefits of Nesting Routes

Nesting routes provides a component-like structure for the routes in your application, offering several advantages:

• Modularity: Child routes enable the encapsulation of specific features or sections of the application, promoting modularity and maintainability;
• Enhanced User Experience: By structuring routes hierarchically, you can control access to certain views, ensuring that users can only navigate to specific views when in a particular context;
• Code Reusability: Child routes facilitate the reuse of components and logic across different sections of the application, leading to cleaner and more maintainable code.

What We Will Be Building?

In this section, we will outline the structure of the application we aim to build to demonstrate the implementation of child routes. Our sample application will consist of a parent component with nested child components, showcasing a practical use case for employing child routes within an Angular application.

Application Structure Overview

The application will feature a clear hierarchy, with the ParentComponent acting as the primary container for the ChildComponent, illustrating the seamless integration of child routes within the application.

Setting Up

To begin implementing child routes in Angular, we need to follow a series of steps to define and integrate these routes within our application. The process involves defining parent routes, registering them, setting up templates, generating child components, and adding child routes along with the presentation code.

Defining Parent Routes

The first step is to define the parent routes within the Angular application. These routes will serve as the foundation upon which the child routes will be nested.

Route Definition Process

• Open the app-routing.module.ts file in your Angular project;
• Define the parent route using the RouterModule.forRoot() method, specifying the path and component for the parent route.

const routes: Routes = [

  { path: 'parent', component: ParentComponent }

];

• Save the changes and proceed to the next step.

Registering Them

Once the parent routes have been defined, the next step is to register these routes within the application to ensure their accessibility and functionality.

Route Registration Process

• Open the app.module.ts file in your Angular project;
• Import the RouterModule and Routes from @angular/router;
• Register the defined routes using the RouterModule.forRoot() method within the importsarray of the @NgModule decorator.

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

@NgModule({

  imports: [RouterModule.forRoot(routes)],

  exports: [RouterModule]

})

export class AppModule { }

By following these steps, the parent routes are now successfully defined and registered within the Angular application, laying the groundwork for the integration of child routes.

Template Setup

With the parent routes in place, the next step involves setting up the templates for the parent and child components, establishing the visual structure of the application.

Template Configuration

• Create the template for the ParentComponent, incorporating the necessary HTML and styling to define its layout and appearance;
• Similarly, create the template for the ChildComponent, ensuring that it complements the design and functionality of the ParentComponent.

By configuring the templates for both the parent and child components, you establish the visual foundation for the application, preparing it for the integration of child routes.

Testing It Out

After setting up the templates and registering the parent routes, it’s crucial to test the application to ensure that the parent route is functioning as expected before proceeding to integrate child routes.

Testing Procedure

• Run the Angular application using the ng serve command;
• Navigate to the specified path for the parent route in a web browser to verify that the parent component is rendered correctly.

By testing the parent route, you can confirm that the initial setup has been executed accurately, providing a solid base for integrating child routes seamlessly.

Generate Child Components

The next phase involves generating the child components that will be nested within the parent component, forming the core structure of the child routes.

Component Generation Process

• Use the Angular CLI to generate the child components by running the following command in the terminal:

ng generate component ChildComponent

• Once generated, the child component files will be created, including the necessary TypeScript, HTML, and CSS files.

By generating the child components, you lay the groundwork for integrating child routes within the application, setting the stage for a hierarchical navigation structure.

Adding Child Routes

After generating the child components, the subsequent step is to add child routes to the existing parent route, enabling the nesting of child components within the parent component.

Child Route Integration Process

• Open the app-routing.module.ts file in your Angular project;
• Define the child routes within the parent route using the children property, specifying the path and component for each child route.

const routes: Routes = [

  {

    path: 'parent',

    component: ParentComponent,

    children: [

      { path: 'child', component: ChildComponent }

    ]

  }

];

• Save the changes and proceed to the final step of adding the presentation code.

By adding child routes to the parent route, you establish a nested structure within the application, allowing for a seamless transition between the parent and child components.

Adding the Presentation Code

The final step involves adding the necessary presentation code to render the child components within the parent component, completing the integration of child routes within the application.

Presentation Code Integration

• Open the template file for the ParentComponent (parent.component.html);
• Use the <router-outlet> directive to specify the location where the child components will be rendered within the parent component’s template.

<div>

  <!-- Other content within the parent component -->

  <router-outlet></router-outlet>

</div>

By integrating the presentation code, you enable the seamless rendering of child components within the parent component, finalizing the implementation of child routes within the Angular application.

Angular Get Form Values

Retrieving form values in Angular is a common task when working with user input. Angular offers two main mechanisms for accessing form values: template-driven forms and reactive forms.

Template-Driven Forms

In template-driven forms, form values can be accessed using directives and template reference variables.

Reactive Forms

Reactive forms manage form values programmatically using form controls.

By integrating form value retrieval mechanisms with child routes, you can create dynamic and interactive Angular applications that respond to user input while maintaining a structured routing system.

Wrapping Up

With the completion of the aforementioned steps, you have successfully set up and integrated child routes within your Angular application, creating a hierarchical navigation structure that enhances the modularity and organization of your application’s routing system. By leveraging child routes, you have unlocked the potential to build more complex and feature-rich SPAs while maintaining a structured and maintainable codebase.

Installing ng-bootstrap

The easiest way to add Bootstrap components into our Angular apps is by using the ng-bootstrap library. This library creates Angular components based on the vanilla version of Bootstrap, making it easy for us to add ready-to-use Bootstrap components into our Angular projects.

To install ng-bootstrap, we can use the following command:

ng add @ng-bootstrap/ng-bootstrap

This command utilizes the Angular CLI and can be used with most Angular projects. Once executed, it will automatically add all the necessary dependencies to our Angular modules, allowing us to use the provided components right away.

It’s worth noting that the latest version of ng-bootstrap is based on the latest version of Bootstrap. So, before proceeding with the installation, make sure to have the latest version of Bootstrap installed in your project.

After running the command, we should see something like this in our app.module.ts file:

import { NgModule } from '@angular/core';

import { BrowserModule } from '@angular/platform-browser';

import { AppRoutingModule } from './app-routing.module';

import { AppComponent } from './app.component';

Adding Common Components

Now that we have ng-bootstrap installed, we can start adding some common Bootstrap components into our Angular app. In this section, we will go through some of the most commonly used components and see how we can integrate them into our project.

Alert

The Alert component in Bootstrap is used to display a short, important message to the user. It can be used for various purposes, such as displaying success or error messages. To add an Alert component in our Angular app, we can use the following code:

<ngb-alert [dismissible]="false" type="success">

  This is a success alert!

</ngb-alert>

This will display a green-colored alert with the text “This is a success alert!” inside it. We can also make the alert dismissible by setting the dismissible attribute to true. Additionally, we can change the type of the alert by changing the type attribute to warning, danger, or info.

Date Picker

Date pickers are essential when working with forms that require users to input dates. With ng-bootstrap, we can easily add a date picker component to our Angular app. Here’s an example of how we can do that:

<input type="text" class="form-control" placeholder="yyyy-mm-dd"

       name="dp" [(ngModel)]="model" ngbDatepicker 

# d="ngbDatepicker">

<button (click)="d.toggle()" class="btn btn-outline-secondary calendar-btn">Select a date</button>

In this code, we have a text input field and a button that triggers the date picker when clicked. The [(ngModel)] directive is used to bind the selected date to a variable named model. We can also customize the format of the date by changing the placeholder attribute.

Modal

Modals are used to display content on top of the current page, usually to grab the user’s attention or ask for confirmation. In Bootstrap, modals are created using the ngb-modalcomponent. Here’s an example of how we can use it in our Angular app:

<button class="btn btn-primary" (click)="open(content)">Launch demo modal</button>

<ng-template 

# content let-modal>

  <div class="modal-header">

    <h4 class="modal-title">Modal title</h4>

    <button type="button" class="close" aria-label="Close" (click)="modal.dismiss('Cross click')">

      <span aria-hidden="true">×</span>

    </button>

  </div>

  <div class="modal-body">

    This is the modal body.

  </div>

  <div class="modal-footer">

    <button type="button" class="btn btn-outline-dark" (click)="modal.close('Save click')">Save</button>

  </div>

</ng-template>

In this code, we have a button that triggers the modal when clicked. The `content` template reference variable is used to define the content of the modal. We can also add a header and footer to our modal by using the appropriate Bootstrap classes.

Table

Tables are commonly used to display data in a structured format. ng-bootstrap provides us with a ngb-table component that allows us to create tables in our Angular app easily. Here’s an example of how we can do that:

<table ngbTable 

# table [data]="data" [columns]="columns">

  <tr *ngFor="let row of table.data">

    <td *ngFor="let cell of row.cells">{{ cell }}</td>

  </tr>

</table>

In this code, we have defined the data and columns for our table in the component file. Then, we use the ngbTable directive to bind the data and columns to our table. We can also customize the appearance of our table by adding Bootstrap classes to the table element.

Text Inputs and Dropdowns

Bootstrap provides us with various styles for text inputs and dropdowns, making it easier to create forms in our Angular app. Here’s an example of how we can use these components:

<form>

  <div class="form-group">

    <label for="exampleFormControlInput1">Email address</label>

    <input type="email" class="form-control" id="exampleFormControlInput1" placeholder="name@example.com">

  </div>

  <div class="form-group">

    <label for="exampleFormControlSelect1">Example select</label>

    <select class="form-control" id="exampleFormControlSelect1">

      <option>1</option>

      <option>2</option>

      <option>3</option>

      <option>4</option>

      <option>5</option>

    </select>

  </div>

  <div class="form-group">

    <label for="exampleFormControlTextarea1">Example textarea</label>

    <textarea class="form-control" id="exampleFormControlTextarea1" rows="3"></textarea>

  </div>

</form>

In this code, we have a form with three different input fields – email, select, and textarea. We can also add validation to these fields by using Bootstrap’s built-in validation classes.

Bootstrap Theming

One of the best things about Bootstrap is its ability to be easily customized and themed. With ng-bootstrap, we can also apply custom themes to our Angular app. To do so, we need to import the Bootstrap SCSS files into our project.

First, we need to install the bootstrap package using npm:

npm install bootstrap

Then, we can import the necessary SCSS files in our styles.scss file:

@import "~bootstrap/scss/bootstrap";

@import "~@ng-bootstrap/ng-bootstrap/index";

Now, we can use Bootstrap’s variables and mixins to customize our app’s theme. For example, we can change the primary color of our app by overriding the $primary variable in the variables.scss file.

Angular Child Routes

In addition to integrating Bootstrap elements, Angular also offers the functionality of child routes. This feature allows for the modularization of routes within an Angular application, enhancing its scalability and maintainability. Child routes can be utilized to encapsulate specific features or sections of an application, enabling a more granular approach to routing and navigation.

By incorporating child routes into our Angular application alongside Bootstrap integration, we can construct highly organized and responsive web applications that adhere to modern design standards. This amalgamation empowers developers to create complex yet intuitive user experiences, ensuring the seamless navigation and interaction within the application.

Conclusion

In this article, we have learned how to install and use Bootstrap in Angular using the ng-bootstrap library. We have also explored some of the most commonly used components and seen how we can integrate them into our Angular app. Additionally, we have learned how to apply custom themes to our app using Bootstrap’s SCSS files.

Among various design patterns in JavaScript, the Module Pattern shines in enhancing maintainability and reusability. Establishing a structured environment with public and private access levels, this pattern safeguards data integrity, fostering clean and efficient code.

Implementing the Module Pattern in JavaScript

JavaScript’s absence of native module support has led to inventive solutions, with CommonJS modules taking the lead. Primarily utilized in Node.js, this module pattern features a concise syntax tailored for synchronous loading on the server side.

```javascript

// CommonJS Module Example

const commonJSModule = require('module');

// Utilize module functionality

commonJSModule.method();

```

AMD (Asynchronous Module Definition) Unveiled

In contrast, AMD, represented by RequireJS, introduces a slightly more intricate syntax. Designed for asynchronous loading on the client side, it offers versatility and has gained widespread acceptance in the JavaScript community.

```javascript

// AMD Module Example

define(['dependency'], function(dependency) {

 // Utilize dependency

 dependency.method();

});

```

Securing Privacy: Private Access Levels and Encapsulation

At the core of the Module Pattern is encapsulation, ensuring the privacy of state through closures. By sidestepping exposure to the global scope, the module pattern mitigates potential errors and conflicts, establishing a secure coding environment.

```javascript

// Module Pattern with Private Access

const myModule = (function () {

 let privateVariable = 'I am private';

 return {

  getPrivateVariable: function () {

   return privateVariable;

  },

  setPrivateVariable: function (value) {

   privateVariable = value;

  }

 };

})();

myModule.getPrivateVariable(); // Returns: 'I am private'

myModule.setPrivateVariable('Now exposed');

myModule.getPrivateVariable(); // Returns: 'Now exposed'

```

Sculpting Reusable Code

At the heart of the module pattern lies the ability to craft reusable code. By encapsulating variables within a function and returning an object, developers can structure applications for optimal readability and maintenance.

```javascript

// Creating Reusable Code with Module Pattern

const reusableModule = (function () {

 let privateData = 'I am encapsulated';

 return {

  getData: function () {

   return privateData;

  },

  setData: function (value) {

   privateData = value;

  }

 };

})();

reusableModule.getData(); // Returns: 'I am encapsulated'

reusableModule.setData('Updated data');

reusableModule.getData(); // Returns: 'Updated data'

```

Crafting Private Methods in the Module Pattern

Harnessing the power of closures, the module pattern facilitates the creation of private methods. This circumvents the absence of access modifiers in JavaScript, offering a means to restrict access to specific functionalities.

```javascript

// Creating Private Methods with Module Pattern

const methodModule = (function () {

 const privateMethod = function () {

  return 'I am a private method';

 };

 return {

  publicMethod: function () {

   return privateMethod();

  }

 };

})();

methodModule.publicMethod(); // Returns: 'I am a private method'

```

Evolution: The Revealing Module Pattern

A transformative shift within module patterns, the revealing module pattern optimizes code organization. By exposing specific variables and methods through an object literal, it strikes a balance between encapsulation and functionality.

```javascript

// Revealing Module Pattern Example

const revealingModule = (function () {

 const privateVariable = 'I am private';

 const publicVariable = 'I am exposed';

 const privateMethod = function () {

  return 'I am a private method';

 };

 const publicMethod = function () {

  return 'I am an exposed method';

 };

 return {

  publicVariable,

  publicMethod

 };

})();

revealingModule.publicVariable; // Returns: 'I am exposed'

revealingModule.publicMethod(); // Returns: 'I am an exposed method'

```

The Dynamics of Immediately Invoked Functional Expressions (IIFE)

Within module patterns, Immediately Invoked Function Expressions (IIFE) play a pivotal role. By returning an object within the function, the module pattern ensures the encapsulation of private variables and functions.

```javascript

// IIFE in Module Pattern

const iifeModule = (function () {

 // Private variables and functions

 return {

  // Public variables and functions

 };

})();

```

Embracing Code Encapsulation: Private Methods

Expanding the boundaries of the module pattern, private methods come to the forefront. Leveraging closures, developers can create functions inaccessible outside the module, reinforcing code encapsulation.

```javascript

// Module Pattern with Private Methods

const privateMethodModule = (function () {

 const privateMethod = function () {

  return 'I am a private method';

 };

 return {

  publicMethod: function () {

   return privateMethod();

  }

 };

})();

```

Transformative Strategies: The Revealing Module Pattern

A paradigm shift within module patterns, the revealing module pattern optimizes code organization. By exposing specific variables and methods through an object literal, it strikes a balance between encapsulation and functionality.

```javascript

// Revealing Module Pattern Example

const revealingModule = (function () {

 const privateVariable = 'I am private';

 const publicVariable = 'I am exposed';

 const privateMethod = function () {

  return 'I am a private method';

 };

 const publicMethod = function () {

  return 'I am an exposed method';

 };

 return {  publicVariable,  publicMethod

 };

})();

```

Basic Usage of Ng Generate

The Angular CLI simplifies component creation with the `ng generate component` command. For brevity, it can be shortened to `ng g component`. This command generates not only the component but also the associated test files. By default, the TypeScript compiler and other build tools are automatically added.

Ng Generate Components & Options

The `ng generate component` command supports various options, allowing for customization and flexibility. These include flags like `–change-detection` to set the change detection strategy, `–flat` to create files at the project’s top level, and `–module` to specify the module for component registration.

Using ng g to Generate Component Files

Practical examples illustrate the command’s versatility. For instance, running `ng g component Foo –inline-style –inline-template –selector FooBar –style scss` generates a component named ‘Foo’ with inline styles and templates, a custom selector (‘FooBar’), and uses SCSS as the CSS preprocessor.

Advanced Component Customization

To further enhance your components, Angular CLI provides advanced customization options. Explore flags like `–display-block` to add CSS styling, `–export` to export the component, and `–view-encapsulation` to isolate the component using strategies like Emulated or ShadowDom.

Best Practices and Tips for Component Generation

• Consistent Naming: Maintain a consistent naming convention for components to enhance code readability and organization;
• Selective Generation: Use flags such as `–skip-tests` or `–skip-selector` to skip unnecessary file generation, optimizing the project structure;
• Standalone Components: When applicable, use the `–standalone` flag to generate independent components that can be easily reused across projects.

Distinction Between Angular Components and Modules

Before diving into two-way data binding, it’s crucial to understand the Angular architecture, specifically the roles of components and modules. Components control sections of the screen, while modules group related components, directives, and services, facilitating a modular and cohesive application structure.

Implementing Two-Way Data Binding

Two-way data binding in Angular synchronizes the model and the view, allowing changes in the user interface to directly update the application state and vice versa. This bi-directional flow is achieved using the ngModel directive within the FormsModule.

Demonstrating Two-Way Data Binding with an Example

To illustrate two-way data binding, we will create a simple typing game using the Angular CLI. This game will display user input in real-time, showcasing the immediate reflection of model changes in the view.

1. Create a new Angular project: ng new twoway;
2. Opt for CSS and decline Angular routing when prompted;
3. Navigate to your new project: cd twoway and serve it with ng serve.

Replace the content in app.component.html with a basic input field bound to a component property using ngModel, demonstrating the user’s input in real time.

Integrating ngModel for Simplified Data Binding

Angular’s ngModel directive streamlines the two-way data binding process, encapsulating both the event and property binding in a single syntax. To utilize ngModel, include the FormsModule in your application’s main module.

By integrating ngModel, you simplify the data binding process, enhancing form handling and user interaction within your Angular applications.
