Employee Management System Angular 18 | Angular 18 Project

Science & Technology

Introduction

Welcome back to Learning Partner! If you're new here, please consider subscribing. In today's walkthrough, we'll be building an Employee Management Application using Angular 18. This project is a common task encountered during technical interviews, and completing it will improve your understanding of CRUD operations, as well as API integrations.

Project Overview

We will develop an Employee Management System, which caters to frequent CRUD operations in Angular applications. This application will primarily consist of four main modules:

  1. Login Module: A static login page where users can enter their credentials.
  2. Employee Module: A portal for managing employee CRUD operations. Users can create, edit, list, and delete employees.
  3. Project Module: This will support the creation and management of various projects within the organization.
  4. Project Employee Module: This module will link employees to respective projects.

Lastly, we will have a Dashboard that summarizes key statistics like total employees, total projects, recently hired employees, and the latest projects.

Step-by-Step Development Process

Initial Setup

First, we need to create a new Angular project and set up the necessary packages and configurations. Use the following command to create a new Angular project:

ng new employee-management

Once the project is created, install Bootstrap and Font Awesome for styling:

npm install bootstrap font-awesome

Make sure to include them in your angular.json file under styles.

Creating Components

Next, we'll create several components for each module:

  • Login Component: Handles user authentication.
  • Employee Component: For managing employee records.
  • Project Component: For managing project information.
  • Project Employee Component: To manage associations between projects and employees.
  • Dashboard Component: Displays all the summary information.

You can generate components using the Angular CLI command:

ng generate component <component-name>

Routing Configuration

Setting up routing is crucial for navigation in our application. We'll configure routes to redirect users to various components. Make sure your main routing module (app-routing.module.ts) includes paths for login, employee, project, project employee, and dashboard.

Creating Services and API Integration

To interact with our backend APIs, we will define a service (let's call it MasterService). This service will contain all API calls necessary to interact with employee data, project data, and dashboard data.

Use Angular's HttpClient module to perform GET, POST, PUT, and DELETE operations.

Implementing CRUD Operations

We'll implement the standard CRUD operations for employees, projects, and project employees:

  1. Create: Users can add a new record.
  2. Read: Users can view a list of all records.
  3. Update: Users can edit existing records.
  4. Delete: Users can remove records as necessary.

We’ll also provide visual feedback and validation during these operations.

Building the Dashboard

In the dashboard component, we will summarize the statistics using a separate endpoint. We will show the total count of employees, projects, and recently added information, enhancing the user experience with quick stats.

Final Thoughts

This Employee Management System is an effective way to showcase your Angular skills. As a hands-on project, it reinforces learning key concepts, such as routing, service use, and dynamic data binding. Once you're comfortable with the system, you can extend its functionality by adding advanced features, improving the UI, or even integrating more complex state management systems.
