Ecommerce Application In Angular From Scratch

Are you a beginner looking to learn Angular? This tutorial is perfect for you! In this article, we will walk you through the process of creating an Ecommerce application using Angular, step by step.

What is Angular?

Angular is a powerful JavaScript framework that allows developers to build dynamic web applications. It is maintained by Google and provides a structured approach to web development, making it easy to create reusable components and manage application state.

Getting Started

The first step is to set up your development environment. Make sure you have Node.js installed on your machine, as we will be using the Node package manager (npm) to manage dependencies.

To create a new Angular project, open up your terminal and run the following command:

ng new ecommerce-app

This will create a new directory called “ecommerce-app” with the basic structure of an Angular application.

Creating Components

Angular applications are built using components. Components are self-contained units of code that handle a specific part of your application’s logic and user interface. In our Ecommerce application, we will create components for the home page, product listing page, and shopping cart.

To create a new component, navigate to the “src/app” directory in your project and run the following command:

ng generate component home

This will create a new directory called “home” with the necessary files for our home page component. Repeat this process to create components for the product listing page and shopping cart.

Routing

In order to navigate between different pages of our application, we will need to set up routing. Angular provides a built-in router that makes it easy to handle navigation.

To set up routing, open the “app-routing.module.ts” file in the “src/app” directory and define the routes for your application. For example:


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

@NgModule({
imports: [RouterModule.forRoot(routes)],
exports: [RouterModule]
})
export class AppRoutingModule { }


This code defines three routes for our application: the home page, product listing page, and shopping cart. The “path” property is the URL path that will trigger the corresponding component.

Interacting with APIs

In order to display products and handle user actions like adding items to the shopping cart, we will need to interact with APIs. Angular provides the HttpClient module that makes it easy to send HTTP requests and handle responses.

In our product listing component, for example, we can make an HTTP request to fetch a list of products:


import { Component, OnInit } from '@angular/core';
import { HttpClient } from '@angular/common/http';

ngOnInit() {
this.http.get('/api/products').subscribe((response: any[]) => {
this.products = response;
});
}
}


This code fetches the list of products from the API endpoint “/api/products” and stores it in the “products” property of the component.

Conclusion

Congratulations! You have successfully created an Ecommerce application using Angular from scratch. You’ve learned how to set up a development environment, create components, set up routing, and interact with APIs.

Angular is a powerful framework that can be used to build complex web applications. Keep exploring and practicing to further enhance your skills! Happy coding!
