Build A To-do list Using React JS Mini Project | useState Hook & Conditionals

React useState is a powerful tool, so for today’s React tutorial, we will get started with building a to-do list using react js . By the end of this tutorial, you will have your first react application by using use state methods and conditional rendering.

useState : returns a stateful value | allows adding of state to a functional component.

The list of functionalities that we will build is as follows:

  1. How to make this form center using react js and styling
  2. How to make use of useState
  3. How to use conditional rendering to build our logic for the to-list application.
  4. How to manipulate use map function to iterate the data.
  5. Reset the value of the input field.
  6. Reset the whole value.

hope you are Build A To-do list Using React JS Mini Project | useState Hook & Conditionals

Prerequisite:

  1. IDE of choice (this tutorial uses VS Code, you can download it here)
  2. npm
  3. create-react-app

Basic Setup: To begin a new project using create-react-app, launch PowerShell or your IDE’s terminal and enter the following command:

You can give your project name like here I m giving β€œmyapp,” but you can change it to something different like β€œmy-first-react-website” for now.

npx create-react-app 

Enter the following command in the terminal to navigate to your react-sidebar-dropdown folder:

	cd my_login

Here is the folder structure for our application.

Here i am writing the code for index.html also so that it would be easy for the user to copy and paste the dependencies or cdn for bootstrap which we are using in our application

index.html

Once the packages and dependencies are finished downloading, start up your IDE and locate your project folder. Let’s start Create our To do app . So here in the first step, we are going to target the App.js first

App.js

import './App.css';
import TodoList from './TodoList';

function App() {
  return (
    <>
      <TodoList/>
    </>
  );
}

export default App;

Lets move to styling part so that we can style app.css

App.css

.container
{
  width: 400px;
  height: 400px;
  background-color: rgb(255, 255, 255);
  border-radius: 25px;
  padding: 25px;
  position: relative;
}

.container_model
{
  width: 400px !important;
  height: auto !important;
  background-color: rgb(255, 255, 255);
  position: relative !important;
}

.vertical-center {
  margin: 0;
  position: absolute;
  top: 80%;
  left: 50%;
  -ms-transform: translate(-50%, -50%);
  transform: translate(-50%, -50%);
}

.btn_area
{
  border: none;
  border-radius: 13px;
  padding: 18px 138px;
  font-weight: 600;
}

.space_betwwn
{
  display: flex;
  justify-content: space-between;

}

#dropdown-basic
{
  background-color: #DDDDDD !important;
    border: none !important;
}

.list-container {
  max-height: calc(100vh - 570px); /* Adjust the height as needed based on your layout */
  overflow-y: auto;
}

::-webkit-scrollbar {
  width: 10px;
}

/* Track */
::-webkit-scrollbar-track {
  background: #f1f1f100;
}

/* Handle */
::-webkit-scrollbar-thumb {
  background: #c6c6c600;
  border-radius: 5px;
}

/* Handle on hover */
::-webkit-scrollbar-thumb:hover {
  background: #c6c6c600;
}

Lets move to Todo logic part where we have to write all the logic and our styling part . First we will start with TodoList.js

TodoList.js

Lets start to write TodoList.js code .

First we have to install bootstrap package because we are using bootstrap

Here is the npm package you can install to use some of its components.

npm install react-bootstrap bootstrap

Lets import some of code from bootstrap

And then after that we have to write all the code for the rest of the list . We have TodoList.js code for the todo List and after that TodoList.css .

import React from 'react'
import { useState } from 'react';
import Button from 'react-bootstrap/Button';

import Dropdown from 'react-bootstrap/Dropdown';

const TodoList = (props) => {
    const [show, setShow] = useState(false);
    const [activiy,setActivity] = useState("");
    const [listData,setlistData] = useState([]);
    const handleClose = () => setShow(false);
    const handleShow = () => setShow(true);

    const addActivity = () =>{
        setlistData(()=>{
            const updatedList = [...listData,activiy]
            console.log(updatedList)
            setActivity('');
            return updatedList
        })
        handleClose();
    }

    const removeActivity = (i) => {
        const updatedListData = listData.filter((elem,id) => {
            return i!=id;
        })
        setlistData(updatedListData);
    }

    const removeAll = () => {

  )
}

export default TodoList

TodoList.css

Lets write our styling part for the todolist to make our tolist look like what we have mention in ui design .

.container {
    display: flex;
    flex-direction: column;
    /* max-height: calc(100vh - 0px); */
  }
  
  .list-container {
    margin-top: 20px;
    flex: 1 1;
    overflow-y: auto;
    border-radius: 10px;
  }
  
  .btn-container {
    margin-top: auto;
    margin-bottom: 20px;
  }
  
  .reset_container
  {
    display: flex;justify-content: space-between;
  }

  #contained-modal-title-vcenter
  {
    font-weight: 700 !important;
  }
  .contained-modal-title-vcenter2
  {
    font-weight: 700 !important;
  }

Let’s write our Index.css code. For the background change and the align the item at the center.

@import url('https://fonts.googleapis.com/css2?family=Inter:wght@100;200;300;400;500;600;700;800;900');
 
html,
body {
  width: 100%;
  height: 100%;
  font-family: 'Inter', sans-serif;
  display: flex;
  align-items: center;
  justify-content: center;
  background: linear-gradient(90deg, #FFFBFB 0%, #FFF4F1 28.65%, #F7F9F1 56.77%, #F7FDF7 99.67%, rgba(255, 255, 255, 0.00) 100%);
}
