Building a To-Do List App with Angular: A Comprehensive Guide

Task Management Made Easy: Crafting a To-Do List App Using Angular

Introduction

In the fast-paced world we live in, staying organized is crucial. A to-do list app can be a lifesaver, helping us manage tasks efficiently. In this article, we’ll dive into the process of building a To-Do List App using Angular, a popular front-end framework. Follow along for a step-by-step guide, complete with code examples.

Getting Started with Angular

What is Angular?

Angular is a powerful JavaScript framework maintained by Google for building dynamic web applications. It uses TypeScript, a superset of JavaScript, to enhance the development experience with features like static typing.

Setting Up Your Angular Environment

Before we start coding, ensure you have Node.js and npm installed on your machine. Use the following commands to install Angular CLI globally:

npm install -g @angular/cli

Now, create a new Angular project:

ng new todo-list-app
cd todo-list-app

Creating the To-Do List App Components

Component Structure

Angular applications are built using components. Let’s create the necessary components for our To-Do List App:

  1. AppComponent: The main component that holds the overall structure.
  2. TaskListComponent: Displays the list of tasks.
  3. TaskItemComponent: Represents an individual task.
  4. AddTaskComponent: Allows users to add new tasks.

Building the Components

app.component.html

<!-- app.component.html -->
<div>
  <h1>Your To-Do List</h1>
  <app-task-list></app-task-list>
  <app-add-task></app-add-task>
</div>

task-list.component.html

<!-- task-list.component.html -->
<ul>
  <li *ngFor="let task of tasks">
    <app-task-item [task]="task"></app-task-item>
  </li>
</ul>

add-task.component.html

<!-- add-task.component.html -->
<input [(ngModel)]="newTask" placeholder="Enter a new task" />
<button (click)="addTask()">Add Task</button>

Implementing Functionality

Now, let’s add functionality to our components.

task-list.component.ts

// task-list.component.ts
import { Component } from '@angular/core';

@Component({
  selector: 'app-task-list',
  templateUrl: './task-list.component.html',
})
export class TaskListComponent {
  tasks: string[] = ['Task 1', 'Task 2', 'Task 3'];
}

add-task.component.ts

// add-task.component.ts
import { Component } from '@angular/core';

@Component({
  selector: 'app-add-task',
  templateUrl: './add-task.component.html',
})
export class AddTaskComponent {
  newTask = '';
  addTask() {
    if (this.newTask.trim() !== '') {
      this.tasks.push(this.newTask);
      this.newTask = '';
    }
  }
}

Styling Your App

Enhance the visual appeal of your app by adding some simple styles. Create a file styles.css in the src folder and include your styling:

/* styles.css */
body {
  font-family: 'Arial', sans-serif;
  background-color: #f4f4f4;
  margin: 0;
  padding: 0;
}

div {
  max-width: 600px;
  margin: 50px auto;
  background-color: #fff;
  padding: 20px;
  border-radius: 8px;
  box-shadow: 0 4px 8px rgba(0, 0, 0, 0.1);
}

h1 {
  color: #333;
}

Include the stylesheet in your angular.json file:

"styles": [
  "src/styles.css"
],

FAQ Section

Q: How can I enhance the functionality of my To-Do List App?
