React Todo App
React Todo App – Complete Beginner Project (2026)
Building a Todo App in React is one of the best ways to understand core concepts like state, events, and component structure. This project helps you apply what you have learned and build a real-world application.
What is a Todo App
A Todo App is a simple application that allows users to add, delete, and manage tasks. It is commonly used as a beginner project in React to understand how dynamic UI works.
Features of Todo App
Add new tasks
Delete tasks
Mark tasks as completed
Display list of tasks
Project Structure
src/
│── components/
│── App.js
│── index.js
You can create a separate component for managing tasks.
Building Todo App Step-by-Step
Step 1: Setup State
function App() {
const [tasks, setTasks] = useState([]);
Step 2: Add Task Function
setTasks([…tasks, task]);
};
Step 3: Delete Task Function
const newTasks = tasks.filter((_, i) => i !== index);
setTasks(newTasks);
};
Step 4: Display Tasks
<div>
{tasks.map((task, index) => (
<div key={index}>
<p>{task}</p>
<button onClick={() => deleteTask(index)}>Delete</button>
</div>
))}
</div>
);
}
How This Project Works
The Todo App uses state to store tasks. When a user adds or deletes a task, the state updates and React re-renders the UI automatically.
