Angular Helps Web App Development

How Angular Helps Web App Development: A Case Study of Onlineplanetapps

Angular is a popular and powerful framework for building web applications. It is based on TypeScript, a superset of JavaScript that adds static typing and other features. Angular provides a component-based architecture, a rich set of libraries, and a suite of developer tools that make web development easier and more productive. In this essay, I will discuss how Angular helps web app development by using onlineplanetapps as a case study.

Onlineplanetapps is a company that develops web apps for various clients. They use Angular as their main framework for creating user interfaces that are scalable, performant, and user-friendly. They also leverage the features and benefits of Angular to improve their development process and quality. Here are some examples of how they do that:

Component-Based Architecture

One of the core features of Angular is its component-based architecture. A component is a reusable piece of UI that has its own logic, template, and style. Components can be nested and composed to create complex user interfaces. Components also communicate with each other through inputs and outputs, which are properties that pass data between components.

Onlineplanetapps uses components to create modular and maintainable user interfaces that are easy to test and reuse. They also use components to implement different features and functionalities for different clients. For example, they have a component that displays a list of products, a component that shows a product detail, a component that handles the shopping cart, etc. They can then combine these components to create different web apps for different e-commerce clients.

Components are defined by using the @ Component () decorator, which specifies the selector, template, and style of the component. For example, the following code defines a simple component that displays a greeting message:

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

selector: ‘app-greeting’,
template: `<h1>Hello {{name}}</h1>`,
style: `h1 { color: blue; }`
export class GreetingComponent {
name = ‘Angular’;

To use this component in another component’s template, we can simply write:


This will render the following HTML:

<h1>Hello Angular</h1>

Components are the building blocks of Angular applications. They allow us to create modular and maintainable user interfaces that are easy to test and reuse.

Rich Set of Libraries

Another feature of Angular is its rich set of libraries that cover a wide variety of features and functionalities. Some of the most commonly used libraries are:

• Angular Router: This library provides a service that enables navigation among views. It also supports features such as lazy loading, guards, resolvers, and route parameters.

• Angular Forms: This library provides two ways to create forms: template-driven and reactive. Template-driven forms rely on directives to bind the form elements to the component’s properties. Reactive forms use a model-driven approach that creates form controls programmatically and synchronizes them with the component’s properties.

• Angular HttpClient: This library provides a service that simplifies making HTTP requests and handling responses. It also supports features such as interceptors, observables, and error handling.

• Angular Material: This library provides a collection of UI components that implement Google’s Material Design guidelines. It includes components such as buttons, cards, dialogs, menus, tables, and more.

• Angular Animations: This library provides a way to animate elements using CSS transitions and keyframes. It also supports features such as triggers, states, transitions, and queries.

Onlineplanetapps uses these libraries to implement common web app features and functionalities without reinventing the wheel. They also use these libraries to create consistent and appealing user interfaces that match their clients’ expectations and requirements. For example, they use Angular Router to handle navigation among different views in their web apps. They use Angular Forms to create forms that validate user input and submit data to their backend services. They use Angular HttpClient to make HTTP requests to their backend services and handle responses accordingly. They use Angular Material to create UI components that follow Google’s Material Design guidelines. They use Angular Animations to add transitions and effects to their UI elements.

These are just some examples of the many libraries that Angular offers. These libraries make it easier to implement common web app features and functionalities without reinventing the wheel.

Suite of Developer Tools
The last feature of Angular that I will discuss is its suite of developer tools that help developers create, build,
