MERN Comment Reply System Implementation With Redux Toolkit Query | Node Express | MongoDB Part-1 😎
Welcome to the first part of our tutorial series on building a MERN (MongoDB, Express, React, Node.js) Comment Reply System with Redux Toolkit Query. In this part, we will focus on setting up the backend using Node.js, Express, and MongoDB.
Setting up the backend
First, let’s create a new directory for our project and navigate into it:
mkdir mern-comment-reply-system cd mern-comment-reply-system
Now, we will initialize a new Node.js project using npm:
npm init -y
Next, let’s install the required dependencies:
npm install express mongoose
We will also need to install additional packages for development, such as nodemon for automatic server restarts:
npm install nodemon --save-dev
Now, let’s create a new file called server.js and set up our Express server:
const express = require('express'); const mongoose = require('mongoose'); const app = express(); // Connect to MongoDB mongoose.connect('mongodb://localhost:27017/mern-comment-reply-system', { useNewUrlParser: true, useUnifiedTopology: true }) .then(() => { console.log('Connected to MongoDB'); }) .catch((error) => { console.error('Error connecting to MongoDB', error); }); // Start the server const PORT = process.env.PORT || 5000; app.listen(PORT, () => { console.log(`Server is running on port ${PORT}`); });
With the backend setup, we can now move on to implementing the models, routes, and controllers for handling comments and replies in the next part of this series.
Stay tuned for Part-2, where we will delve into building the React frontend and integrating Redux Toolkit Query for data fetching and updating.
Thank you for reading!
thank you Sir
Backend code is not included in the github repo?
great tutorial🔥
Could you maybe please implement notifications with rtk query in the future?
Thanks bro… when will be second part come
