Building a Todo App with Angular CLI

This tutorial guides you through building a to-do application using the Angular CLI, a powerful tool for streamlining Angular development. We'll cover key concepts and best practices, culminating in a deployable application on GitHub Pages.

Key Concepts Covered:

• Angular CLI for Project Initialization: Learn how to quickly set up a new Angular project using the ng new command, simplifying the development process.
• TypeScript Class for Todo Items: Define a Todo class to represent individual to-do items, including properties like id, title, and complete status.
• TodoDataService for Data Management: Create a service to handle adding, deleting, updating, and retrieving to-do items, centralizing data logic.
• AppComponent for User Interaction: Implement the main application component to interact with the TodoDataService and manage user input.
• GitHub Pages Deployment: Deploy your completed application to GitHub Pages directly from the Angular CLI.
• Angular Template Syntax: Explore Angular's template syntax for data binding and event handling, creating a dynamic user interface.
• Unit Testing: Write unit tests for the Todo class and TodoDataService to ensure code correctness and reliability.

Getting Started:

1. Install Angular CLI: Use npm install -g @angular/cli to install the Angular CLI globally. Verify the installation with ng version.
2. Create a New Project: Run ng new todo-app to generate a new project directory.
3. Generate Todo Class: Use ng generate class Todo --spec to create the Todo class and its associated test file.
4. Generate TodoDataService: Use ng generate service TodoData to create the data service.
5. Implement Component Logic: Develop the AppComponent to handle user interaction and data binding.
6. Deploy to GitHub Pages: Use ng github-pages:deploy to deploy your app.

This tutorial provides a solid foundation for building Angular applications. The subsequent articles in this series will delve into more advanced topics and refine the application's architecture. Remember to consult the official Angular documentation for detailed information on each concept.
