Full Stack Application Development with Spring Boot and Angular

Introduction

• Speaker: Junior from Amigos Code
• Course Focus: Building a full stack application with Spring Boot (backend) and Angular (frontend).
• Content Overview: Best practices for application structure, backend connection to MySQL, Angular & TypeScript practices.

Application Overview

• Application Type: Server Manager Application.
• Features: Manage servers by filtering, adding, pinging, and deleting servers.

Application Demonstration

1. Manage Servers: App allows filtering by server status (Up/Down).
2. Adding a New Server: Pop-up form to add servers with fields for IP address, name, memory, type, and status.
3. Ping Server: Attempts to open a connection to a server based on IP.
4. Delete Server: Option to remove servers from the list.
5. Generate Report: Option to print a report of current server statuses.

Technologies Used

• Backend: Spring Boot, MySQL.
• Frontend: Angular, TypeScript.

Spring Boot Backend

Project Initialization

• Use Spring Initializr to bootstrap the Spring Boot application with necessary dependencies:
  • Spring Web
  • MySQL Driver
  • Spring JPA
  • Validation
  • Lombok

Application Structure

1. Models: Create a Server class to represent server data.
   • Fields: ID, IP Address, Name, Memory, Type, Status.
   • Use JPA annotations for database mapping.
2. Repository: Create a ServerRepo interface extending JPA Repository for CRUD operations.
3. Service Layer: Define a ServerService interface to declare service methods.
4. Controller: Create a REST controller to expose endpoints for server management.

Angular Frontend

Application Setup

• Install Node.js and Angular CLI.
• Create a new Angular application using ng new server-app.

Application Structure

1. Enum & Interfaces: Create enums for server statuses and interfaces for server models.
2. Service: Create a service to handle HTTP requests to the Spring Boot backend.
3. Components: Implement components to display server information and manage server actions.

UI Features

• Server Management: List of servers with options to add, delete, ping, and filter.
• Notifications: Implement notifications using Angular Notifier for user feedback on actions.

Handling Server Actions

1. Add Server: Use forms to gather user input and submit to backend API.
2. Delete Server: Confirm deletion and update the server list dynamically.
3. Ping Server: Use observable pattern to provide real-time feedback on server status.
4. Filtering: Implement logic to show only servers matching selected criteria.
5. Generate Report: Create functionality to print or download server information.

Performance Optimization

• Use OnPush Change Detection strategy for better performance in larger applications.

Conclusion

• Final Remarks: The session covered building a full stack application using Spring Boot and Angular emphasizing best practices and performance considerations.
• Encouragement: Engage with the course content to enhance development skills and apply learned techniques in practical scenarios.
