What is the MERN stack?
M in MERN stands for MongoDB. MongoDB is a simple NoSql and object-oriented database technology that is efficient and scalable for large data storage. MongoDB stores data as objects in JSON format, in separate documents instead of storing in rows and columns like in a typical relational database. This increases productivity in the manipulation and retrieval of data in abundance.
E in MERN stack stands for express JS. Express js or express is a node js framework that promotes the rapid development of node-based web and mobile applications. Express supports the MVC framework which helps in building more scalable, structured and dynamic websites. Express focuses more on the back-end or the developer side.
R in MERN stands for React. MERN is similar to MEAN but uses React for the development of front-end web applications rather than using Angular. React is an open-source JavaScript library that allows us to make reusable components for a single-page user interface.
N in MERN stack stands for Node JS. Node JS allows out to write JavaScript on the server or outside of the browser. Node uses an event-driven, non-blocking I/O model that makes it lightweight and effectual, seamless for applications that run across distributed devices.
sudo dnf -y update 
step 2: Install MongoDB
for installing mongoDB you need to first open the file for adding content to your repository.
sudo vi /etc/yum.repos.d/mongodb.repo 
the terminal should give you an ok.
Now install mongoDB by simplifying running
sudo apt install -y mongodb name=MongoDB Repository
baseurl=https://repo.mongodb.org/yum/amazon/2/mongodb-org/4.2/x86_64/
gpgcheck=1
enabled=1
gpgkey=https://www.mongodb.org/static/pgp/server-4.2.asc
sudo dnf install mongodb-org 
sudo systemctl enable mongod.service
sudo systemctl start mongod.service sudo systemctl stop mongod
sudo systemctl restart mongod Step 3: installing Node JS
from fedora 24 and onwards, npm comes in part with node js so you don’t have to install it separately.sudo dnf install nodejs 
dnf module list 
sudo dnf module install nodejs:10 
step 4: install express js
run the following command to get and install express JS in fedora.
First install npm,
npm install -g express 
Now this install express cli to help you in creating the basic web site structure.
Create a new project to test your installation. First create a new folder in which you will get all the dependencies of the project to be created
npm init
mkdir projectName
cd projectName
express
npm install 
Step 5: installing React
you can start by creating a folder and installing all your dependencies in it.
mkdir ReactProject
cd ReactProject npm install -g create-react-app 
npx create-react-app name-of-app 
create-react-app --version
