Designing Applications using Angular

In this post, we are going to go through Designing Applications using Angular how to design Applications using Angular Material, and Angular Animation.

Designing an Application using Angular is a process that involves several steps to create a functional, responsive, and user-friendly application. Here's a brief overview of some key concepts and practices to consider when designing an Angular application:

Designing the UI: A well-designed UI is critical to the success of an application. You should consider the user experience and make sure that the interface is easy to use and intuitive. Angular provides several UI components that can be used to create responsive and user-friendly interfaces. Angular Material is a popular library that provides a wide range of UI components to choose from.
Architecture and Design Patterns: Design patterns are essential to creating a well-structured and maintainable application. The MVC (Model-View-Controller) and MVVM (Model-View-ViewModel) are some of the most commonly used design patterns in Angular. In addition to these, you can also use other patterns such as the Singleton, Observer, or Decorator pattern to solve specific problems in your application.
Data Binding: Data binding is a powerful feature in Angular that allows you to synchronize data between the view and the model. It provides a convenient way to update the user interface based on changes in the model, and vice versa. There are two types of data binding in Angular - One-way data binding and Two-way data binding.
Services and Dependency Injection: Services are used to provide common functionality across different components in an Angular application. Dependency injection is a design pattern that allows you to inject services into the components that need them. This makes it easier to maintain and test your application.
Routing: Routing is a fundamental part of Angular that allows you to create a single-page application with multiple views. It helps to navigate between different views and components of your application. Angular provides a powerful router that can be used to implement complex routing scenarios.
Testing: Testing is a critical part of Angular application development. It helps to ensure that the application works as intended and reduces the risk of introducing new bugs or errors. Angular provides several testing tools such as Jasmine and Karma that can be used to create and run tests for your application.
Deployment: Deploying an Angular application involves several steps such as optimizing the application, bundling the files, and uploading them to a server. Angular provides several tools such as Angular CLI and Webpack that can be used to automate the deployment process.

Design application using Angular Material

Angular Material is a user interface (UI) component library that developers use in their Angular projects in terms of hastening the development process for a stylish and compatible user interface. Angular Material offers you reusable and beautiful UI components like Cards, Inputs, Data Tables, date pickers, and much more.

Step 1 - Install NodeJS:

Install NodeJS: https://nodejs.org/

Step 2 - Install Angular and create an Angular project:

Using following commands:

# Install Angular using the Node Package Manager:
npm install -g @angular/cli
# Create a new Angular application named "design-app" using the Angular CLI using scss as stylesheet and with Angular routing enabled:
ng new design-app --style=scss --routing
# Change directory into the project directory:
cd design-app
# Run the Angular development server locally:
ng serve

Step 3 - Add Angular Material:

In your Angular project, install Angular Material using the following command:

ng add @angular/material

Import Angular Material modules: In your app.module.ts file, import the necessary Angular Material modules you will use in your application. Here's an example:

import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { BrowserAnimationsModule } from '@angular/platform-browser/animations';

import { MatToolbarModule } from '@angular/material/toolbar';
import { MatIconModule } from '@angular/material/icon';
import { MatButtonModule } from '@angular/material/button';
import { MatMenuModule } from '@angular/material/menu';
import { MatFormFieldModule } from '@angular/material/form-field';
import { MatInputModule } from '@angular/material/input';

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

@NgModule({
  imports: [
    BrowserModule,
    BrowserAnimationsModule,
    MatToolbarModule,
    MatIconModule,
    MatButtonModule,
    MatMenuModule,
    MatFormFieldModule,
    MatInputModule
  ],
  declarations: [
    AppComponent
  ],
  bootstrap: [AppComponent]
})
export class AppModule { }

Use Angular Material components in your application: In your app.component.html file, use Angular Material components to design your application

For adding material toolbar, the following HTML snippet is used:

<p>
  <mat-toolbar>
    <span>My Application</span>
  </mat-toolbar>
</p>

There are different types of material toolbar elements available in the Angular material library.

For adding material card, the following HTML snippet is used:

<mat-card>
  <mat-card-content>Simple card</mat-card-content>
</mat-card>

There are different types of material card elements available in the Angular material library.

For adding material buttons, the following HTML snippet is used:

<button mat-button>
	Basic
</button>

There are different types of material button elements available in the Angular material library.

Design application using Angular Animation

we will add a hover animation to a button that changes its background color and text color when the user hovers over it. Here are the below code:

Import the necessary modules: To use Angular Animation, you need to import the BrowserAnimationsModule module and the trigger, state, style, and animate functions from the '@angular/animations' module. Add the following imports to your component file:

import { BrowserAnimationsModule } from '@angular/platform-browser/animations';
import { trigger, state, style, animate } from '@angular/animations';

Add the animation metadata: Define the animation metadata using the trigger function. In this case, we will define an animation that changes the background color and text color of the button when the user hovers over it. Add the following code to your component file:

animations: [
  trigger('hoverAnimation', [
    state('normal', style({
      backgroundColor: '#007bff',
      color: '#fff'
    })),
    state('hover', style({
      backgroundColor: '#fff',
      color: '#007bff'
    })),
    transition('normal <=> hover', animate(200))
  ])
]

This code defines the 'hover animation' trigger with two states: 'normal' and 'hover'. In the 'normal' state, the background color of the button is set to '#007bff' (blue) and the text color is set to '#fff' (white). In the 'hover' state, the background color is set to '#fff' and the text color is set to '#007bff'. The transition between the states is set to take 200ms.

Apply the animation to the button: Finally, we need to apply the 'hoverAnimation' trigger to the button element using the [@hoverAnimation] directive. Add the following code to your component template:

<button [@hoverAnimation]="'normal'" (mouseover)="hover = 'hover'" (mouseout)="hover = 'normal'">Hover Me</button>

This code adds the [@hoverAnimation] directive to the button element and binds it to the 'hoverAnimation' trigger. The 'normal' state is set as the initial state. The (mouseover) and (mouseout) events are used to set the 'hover' state and 'normal' state, respectively.

When you run this code, you will see that the button changes its background color and text color when the user hovers over it. This simple animation adds a nice touch to the user interface and provides visual feedback to the user.

I hope this example helps you understand how to use Angular Animation.
