Prerequisites

  • Basic understanding of React JS
  • Node JS

Step 1 - create-react-app

$ npx create-react-app@latest mynoteapp

Step 2 - Creating TextArea

<textarea id="txt" cols="30" rows="10" placeholder="Enter some text!" value={text} onChange={e => setText(e.target.value)} onKeyDown={keySound}></textarea>

Styling ๐ŸŒˆ

*{
  margin: 0;
  padding: 0;
  box-sizing: border-box;
}
body{
  height: 100%;
  overflow: hidden;
}
textarea{
  width: 100%;
  height: 100vh;
  resize: none;
  margin: 5px;
  font-size: 25px;
  outline: none;
  border: none;
}

So, now the Textarea is covered the whole page without outlines and borders

Step 3 - Add Settings Menu using dat.gui

  • Install data.gui using,
    $ npm i dat.gui
    
  • Import it to Textarea.js
    import * as dat from 'dat.gui';
    
  • Initialize dat.gui
    const gui = await new dat.GUI({hideable: false});
    
  • Create objects
    const obj = {
              fontSize : 25,
              fontFamily : 'monospace',
              saveFile: () => {
                  const btn = document.querySelector('#saveBtn')
                  btn.click()
              }
          }
    
  • Add options 1) Font size
    gui.add(obj, 'fontSize').min(8).max(60).step(1).onChange(e => {
              document.querySelector('textarea').style.fontSize = `${e}px`
          })
    
    2) Font family
    gui.add(obj, 'fontFamily', {
              'Monospace': 'monospace',
              'Roboto': 'Roboto',
              'Poppins': 'Poppins',
              'Cursive': 'Cursive',
          }).onChange(e => {
              document.querySelector('textarea').style.fontFamily = e
          })
    
    3) Save button
    gui.add(obj, 'saveFile')
    

This will create a GUI panel on the top-right corner of the page

GUI panel

Step 4 - Setting up database

  • Go to Google Firebase Console
  • Create a new project, give it a name as you wish
  • Create a new web application Web app
  • Install firebase to your react application
    $ npm install firebase
    
  • Copy your credentials and create fireabse.js in the src directory of your React application

firebase.js

import firebase from "firebase/compat/app"
import "firebase/compat/firestore"

const firebaseConfig = {
    apiKey: "YOUR_API_KEY",
    authDomain: "YOUR_AUTH_DOMAIN",
    projectId: "YOUR_PROJECT_ID",
    storageBucket: "YOUR_STORAGE_BUCKET",
    messagingSenderId: "YOUR_MESSAGING_ID",
    appId: "YOUR_APP_ID"
  };


const app = firebase.initializeApp(firebaseConfig);

const db = app.firestore();


export default db
  • Now go back again to your Firebase project
  • Go to Firestore Database Firestore
  • Create a database
  • And choose production mode
  • Choose any location you want
  • After creating the database, go to the rules tab of the dashboard Rules
  • Paste the following code to the rules playground and publish it
    rules_version = '2';
    service cloud.firestore {
    match /databases/{database}/documents {
      match /{document=**} {
        allow read, write: if true;
      }
    }
    }
    
  • Now go back to your React project

  • Go to Textarea.js and import database

    import db from '../firebase'
    
  • Create a save function
    const handleSave = async () => {
          let slug = tinyid.unique()
          keySound()
          let today = new Date();
          const dd = String(today.getDate()).padStart(2, '0');
          const mm = String(today.getMonth() + 1).padStart(2, '0'); //January is 0!
          const yyyy = today.getFullYear();
          today =  dd + '/' + mm + '/' + yyyy
          await db.collection('notes').doc(slug).set({
              text: text,
              date: today,
          })
          navigate(`/${slug}`)
      }
    
    To generate slug, you can use tiny-unique-id
  • Loading created notes
    useEffect(() => {
          const handleLoad = async () => {
              const doc = await db.collection('notes').doc(slug).get()
              setText(doc.data().text)
          }
          handleLoad()
      }, [slug])
