Create a custom server using http module and explore the other modules of Node JS like OS, path, event.
Step 1: Set Up the Project
Our first task is to set up the React project. This step involves creating the necessary project structure. Here's how you can do it:
1. Create a React App:
Open your terminal and navigate to your preferred directory. Run the following command to generate a new React app. Replace "todo-app" with your desired project name:
npx create-react-app todo-app
This command will create a directory named "todo-app" with all the initial code required for a React app.
2. Navigate to the Project Directory:
Change your working directory to the "todo-app" folder:
cd todo-app
3. Start the Development Server:
Launch the development server with the following command:
npm start
This will open your React app, and youll see the default React starter page in your web browser at 'http://localhost:3000'.
Step 2: Create the App Component
In this step, we create the App component, which serves as the entry point to our Todo List application.
import React from'react';
import TodoList from'./components/TodoList';
function App() {
return (
<div className="App">
<TodoList />
</div>
);
}
exportdefault App;
Step 3: Create the TodoList
src->Component
Now, let's create the 'TodoList' component, which is responsible for managing the list of tasks and handling task-related functionality.
import React, { useState } from 'react';
import TodoItem from './TodoItem';
function TodoList() {
const [tasks, setTasks] = useState([
{
id: 1,
text: 'Doctor Appointment',
completed: true
},
{
id: 2,
text: 'Meeting at School',
completed: false
}
]);
const [text, setText] = useState('');
function addTask(text) {
const newTask = {
id: Date.now(),
text,
completed: false
};
setTasks([tasks, newTask]);
setText('');
}
function deleteTask(id) {
setTasks(tasks.filter(task => task.id !== id));
}
function toggleCompleted(id) {
setTasks(tasks.map(task => {
if (task.id === id) {
return {task, completed: !task.completed};
} else {
return task;
}
}));
}
return (
<div className="todo-list">
{tasks.map(task => (
<TodoItem
key={task.id}
task={task}
deleteTask={deleteTask}
toggleCompleted={toggleCompleted}
/>
))}
<input
value={text}
onChange={e => setText(e.target.value)}
/>
<button onClick={() => addTask(text)}>Add</button>
</div>
);
}
exportdefault TodoList;
Step 4: Create the place the TodoItem in
src->Component
In this step, we create the 'TodoItem' component, which represents an individual task in our Todo List.
import React from'react';
function TodoItem({ task, deleteTask, toggleCompleted }) {
function handleChange() {
toggleCompleted(task.id);
}
return (
<div className="todo-item">
<input
type="checkbox"
checked={task.completed}
onChange={handleChange}
/>
<p>{task.text}</p>
<button onClick={() => deleteTask(task.id)}>
X
</button>
</div>
);
}
exportdefault TodoItem;
These three components, 'App', 'TodoList', and 'TodoItem', work together to create a functional Todo List application in React. The 'TodoList' component manages the state of the tasks, and the 'TodoItem' component represents and handles individual tasks within the list.
Step 5: Styling
To enhance the visual appeal of your Todo List, you can apply some basic styling. Heres an example of how you can style the todo items. In the `App.css` file, add the following styles:
.todo-item {
display: flex;
justify-content: space-between;
margin-bottom: 8px;
}
.todo-itemp {
color: #888;
text-decoration: line-through;
}
Your output should look like this:
