Steps to Create a Backend Server

Preview of Final Output :

Edit, Delete, View Note...

Prerequisites :

NPM & NodeJS ExpressJS MongoDB ReactJS...

Approach to Create Note-Taking App With NodeJS and ExpressJS :

Create a .env file to store the value of PORT on which the backend application will run and also add the mongoDB URL where all data of notes will be stored. The significance of .env file is that it stores all configuration settings for the application and private data that can be accessed in the files but is inaccessible to other people. Create an index.js file where express and node.js will be used to handle servers and routes. Also use CORS Policy (Cross Origin Resource Sharing) that enables the use of other applications on the current one being used. Use a middleware element to parse the request to the body and finally return a response when the server is connected to the backend. Create a function to connect to the database of mongodb using the url specified in the .env file. On successful connection with the database, send a response of a successful message. Create a routes.js file which connects to the Mongoose Model and creates several routes to get, post, delete, update the notes. With each functionality we have also added a response message along with the status code. Create a model.js file and within the file create a Schema model using mongoose and mention the required details you want for the website, such as the topic of the note, the status of the note, the different timestamps, such as when the note was created and when edited, along with the note you would want to phrase. On running the frontend application, the backend successfully connects to the application on creating routes and BrowserRouter in the App.jsx and Main.jsx file respectively. To run the frontend application, you may use Create React Application, or Create Vite Project. In frontend code, we will be creating several components to post, get, delete and update a book using POSTMAN API. We will also give two options to view the notes, one in the table format & the other one in cards format....
