Angular Project From Scratch: A Crash Course in User Management

In this crash course, we will guide you through setting up an Angular project from scratch that focuses on user management functionality. We will also cover the backend setup using MySQL to store user information.

Prerequisites

Before starting, please make sure you have the following prerequisites:

• Node.js and npm installed
• Basic knowledge of HTML, CSS, and JavaScript
• A text editor of your choice (e.g., Visual Studio Code)
• XAMPP or any other similar tool for MySQL setup

Setting Up the Backend with MySQL

Before starting with the Angular project, let’s first set up the backend using MySQL. Follow these steps:

1. Install XAMPP or a similar tool and start the Apache and MySQL services.
2. Open phpMyAdmin through the XAMPP control panel or by visiting http://localhost/phpmyadmin.
3. Create a new database named user_management.
4. Create a table named users with the following columns:

Setting Up the Angular Project

Now that our backend is ready, let’s move on to setting up the Angular project:

1. Create a new folder for your project and navigate to it in the command line.
2. Run the command npm install -g @angular/cli to install the Angular CLI globally on your system.
3. Run the command ng new user-management to create a new Angular project.
4. Navigate to the project folder using cd user-management.
5. Open the project in your text editor.

User Management Functionality

Now let’s add user management functionality to our Angular project:

1. Generate a new component using the command ng generate component user-list.
2. Update the HTML, CSS, and TypeScript files for the component to display a list of users fetched from the backend.
3. Create another component for the user creation form using ng generate component user-form.
4. Update the HTML, CSS, and TypeScript files for the component to handle user creation and sending the data to the backend.

These steps are just a simplified guide, and you can customize your components and functionality according to your requirements.

Connecting Angular with the Backend

To connect our Angular project with the backend, follow these steps:

1. Install the mysql and express packages using npm install mysql express.
2. Create a new file named db.js in the project root.
3. Write code in db.js to establish a connection with the MySQL database and handle CRUD operations.
4. In the Angular component files, import the HttpClientModule and HttpClient from @angular/common/http.
5. Use the HttpClient to make HTTP calls to the backend API and retrieve or send data.

Conclusion

Congratulations! You have set up an Angular project from scratch and implemented user management functionality with a MySQL backend.

This crash course should give you a basic understanding of how to get started with Angular and handle user management. Remember to explore and experiment further to enhance your project according to your requirements.
