How to Build a Todo List with React Hooks useState

by vsasikalabe Updated: Jan 24, 2023

A To-do list is a list created by users to keep track of their daily tasks. You can add whatever tasks need to be done and arrange them on a priority basis. Once a task is completed, you can mark them as completed.  


A To-do list has three main components that are: 

  • Header: the label of the list 
  • List Items: these will include the tasks 
  • Form: adds a task to the list 


We can create the list simply by following some basic steps. Firstly, you must create a React application, then give the header or whatever name you want to assign to your list. Create mock data to test your application (this can be done by using JSON), then we need to read the list of tasks/test data. For this, we can use the useState hook of react. useState in React can be defined as a hook that will allow you to have local/state variables to functional components (i.e.the, more common components). Then we must toggle the task completion, i.e., once a task is completed, we will switch to another task. Then create a button to delete the completed tasks and add new tasks using a form component. 


Here's an example of how to build a Todo List with React Hooks useState;

Preview of the output that you will get on running this code from your IDE.


Code:

In this solution we use the React library.

Instructions

Follow the steps carefully to get the output easily.

  1. Install the Node.js and React on your IDE(preferable Visual Studio Code).
  2. Create React Application using npx create-react-app foldername.
  3. cd foldername.
  4. Open the folder in IDE.
  5. Copy the code using "copy" button above and paste it in App.js file(remove the earlier code from App.js).
  6. Open the terminal from IDE.
  7. npm start to run the file.


I hope you found this useful. I have added the link to dependent libraries, version information in the following sections.


I found this code snippet by searching for 'Building a Todo list with useState using Reactjs' in kandi. You can try any such use case!

Environment Tested

I tested this solution in the following versions. Be mindful of changes when working with other versions.

  1. The solution is created in VS Code 1.73.1 version.
  2. The solution is tested on Nodejs 16.14.2 version.
  3. react 18.2.0 version.


Using this solution, we are able to create a Todo list with useState using Reactjs with simple steps. This process also facilities an easy way to use, hassle-free method to create a hands-on working version of code which would help us to create a Todo list with useState using Reactjs.
