Introduction to the structure of a React to-do app

Today you are taking the first step in creating your own to-do app with React. After the previous exercises, it is now time to apply the knowledge you have learned and create a practical project. In this tutorial, you will not only learn about the structure of the to-do app, but also about the components necessary to implement the functionality. So let's dive straight into it!

Key Insights

• You will learn how to create the basic structure of a to-do app.
• The app consists of two main components: ToDoInput for entering new to-dos and ToDoList for displaying the to-dos.
• React states are used to manage the list of to-dos.

Step-by-Step Guide

Step 1: Setting Up the Project

To get started, you will create a new array of components and remove all unnecessary parts from the app.jsx. So delete all previous implementations in these files.

Step 2: Planning the Components

Plan the structure of the to-do app. Identify the two main components: ToDoInput, where new to-dos will be entered, and ToDoList, where the to-dos will be displayed.

Step 3: Creating Components

Create the ToDoInput component. You can start by building the basic structure of the input component. This should include an input field for the to-do text and a button to add it.

Step 4: Adding the ToDoList Component

Now it's time to create the second component: ToDoList. These components that need to be displayed should still remain empty as we will fill them with content later on.

Step 5: Importing Components into app.jsx

In app.jsx, you will import the two new components. Make sure to use the correct names. Then add the two components to the render method.

Step 6: Styling Elements in ToDoInput

Style the ToDoInput by adding a element for the title "New To Do:" and an input field. Set the type of the input field to text to allow users to enter text.

Step 7: Managing State

Create a state for the to-do text. Use useState to manage the input value and set the initial value to an empty string. Also, add an onChange event to update the state with each input.

Step 8: Preparing App Component for To-Do List

Think about how app.jsx can also store the list of to-dos. You will need to create a state for the to-do items to manage them later on.

Step 9: Initializing To-Dos

Initialize your to-do array in the App component with at least one to-do object containing the text and a status (e.g., false for incomplete).

Step 10: Populating ToDoList with Props

Pass the to-do array as props to the ToDoList component. Make sure to define the structure of the props correctly to ensure that ToDoList can access the array.

Step 11: Displaying To-dos

Use the map function to display the to-dos in the ToDoList. For each to-do element, create a
