How To Create A Todo List App | React JS Project From Scratch

In this tutorial, we will walk through the process of creating a simple todo list app using React JS. React JS is a popular JavaScript library for building user interfaces and is commonly used in web development projects.

Prerequisites

• Basic knowledge of HTML, CSS, and JavaScript
• Node.js and npm installed on your computer
• A text editor like Visual Studio Code or Sublime Text

Setting Up The Project

Start by creating a new directory for your project and navigate into it using the command line. Then, run the following commands to create a new React app:

npx create-react-app todo-list

This will create a new directory called todo-list with a basic React project structure.

Building The Todo List App

Once the project is set up, open it in your text editor and navigate to the src directory. Inside this directory, create a new file called TodoList.js. In this file, we will write the code for our todo list app.

Start by importing the necessary React components:


import React, { useState } from 'react';
import './TodoList.css';


Next, define a functional component called TodoList:


function TodoList() {
const [todos, setTodos] = useState([]);
return (
// TODO: Add JSX for todo list here
);
}


Inside the TodoList component, use the useState hook to create a state variable for storing the todo items. Then, use the map function to display the todo list items on the page.

Styling The Todo List App

Create a new file called TodoList.css in the src directory and add the necessary styles for the todo list app. You can use CSS to customize the appearance of the todo list items, input field, and buttons.

Adding Functionality

Finally, add functionality to the todo list app by adding input fields for entering new todo items and buttons for adding, editing, and deleting todo items. You can use event handlers and state updates to manage the todo list data.

Conclusion

By following these steps, you can create a simple todo list app using React JS. This project will help you understand the basics of React components, state management, and event handling. You can also expand on this project by adding more features such as filtering, sorting, and data persistence.
